ETA on 4.1
Hi List Is there any way to get an estimate of the release date of the next stable version of MySQL? The reason I'm asking; I am currently busy configuring new webservers, but it is not crucial as to the exact time I deploy them ( they will replace currently running servers), so if I knew 4.1 would be released in a week or 2 ( or 3 or 4 ...), I could maybe wait for it before I deploy the new servers ( will just save me one migration), and I'd hate to deploy the servers and have 4.1 stable release come out the next day Thanks -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Be careful with that last if() statement. I would either change the

read '$flag = true' or 'if( isset($flag) )'
It's quite possible that I'm mistaken, but I believe that 'if($flag)'
would
evaluate to false if '$flag = false'.
The constant FALSE (or false) will never evaluate as a TRUE condition.
if ($flag = true) // this assigns TRUE to $flag and then the
// value of $flag will be evaluated.
if (isset($flag)) // will evaluate as TRUE because $flag has a value
// assigned. It's not NULL.
// -- regardless of what the value is.
if ($flag) {
-- or (assuming $flag is initialized) --
if ($flag === TRUE) {
... so either would be the correct construct here.

RE: RAID hardware suggestions/experience
RE: SCSI needed for best performance - While this is true in some cases, if you are using striping or any RAID level (RAID 5 for example) that splits reads and writes across drives, then there will be several IDE channels feeding data to the RAID card at a time. Two ATA100 IDE channels will accept and provide data faster than the PCI bus that the card is plugged into can. The result is that you can use cheap IDE drives and get the same performance as the very fastest SCSI drives. I don't think this is generally true. For database-type applications, even with multiple drives, throughput is usually limited by seeks rather than data transfer rate. One of the capacity that Scsi drives have that IDE drives don't is the ability to send multiple overlapping transfers to the drive, which can then execute them out of order. Firstly, it can do escalator seeking - sort into position on the disk so as to minimise the number of end-to-end seeks. Secondly, it can trade off short seeks against rotational latency, because it knows tha angular position of the disk at any time. I found that the second feature alone added about 25% to net performance.

inserting unicode into 4.1.0.alpha - again a slightly absurd solution
hi! i had some trouble inserting utf-8 unicode into a table in mysql 4.1.0.alpha. i creat the table with CREATE TABLE chartab ( . ) TYPE=MyISAM CHARSET=utf8; then I tried to insert utf-8 data, using a file with sql statements: mysql --default-character-set=utf8 test test-insert.sql but all i ever got was latin1 in my table. specifying --default-character-set on the comman line didn't help, using SET CHARACTER SET utf8 and/or SET NAMES utf8 as the first sql-command did not help. The only way I got it to work correctly is using the CONVERT function for every utf8 string: INSERT INTO chartab VALUES (...

The new inserted records will not be seen by any of the clients that have a READ lock until they release their read locks But in Section 6.7.2 Lock Tables/Unlock Tables Syntax If a thread obtains a READ lock on a table, that thread (and all other threads) can only read from the table. If a thread obtains a WRITE lock on a table, then only the thread holding the lock can READ from or WRITE to the table. What am I missing pls? Can I, with a READ Lock, still write to the table? Is the following assumption correct? READ Lock - Thread/Client with Lock, can write to locked Table, and is ONLY ONE who can until Lock released.

Re: Apstrophee Errors
Actually, I think the more appropriate fix for this problem, would be to do what a call to mysql_escape_string does. The problem occuring is common, the characters being used are taken literally as part of the string, rather than as quotes what you want them as. MySQL's C library has the function mysql_escape_string which takes various characters like single and double quotes, and turns them into their binary equivilents, so they are interpreted correctly, and not as part of the string termination. Example: SELECT * FROM Users WHERE Username='%s'; Where %s is Test's, without quotes, will produce an error. The single quote in Test's will end the string which is matching against Username, which in effect has just botched your SQL statement. The mysql_escape_string will turn the string Test's into something like Test\027s which will be parsed correctly in the SQL statement itself.

RE: Triggers
[snip] The argument usually used by people looking for - triggers - functions + procedures - foriegn keys is the persuit of data integrity, and encapsulating business logic within the database. Whilst this goal is noble, it can be fully achieved within the application code, and not in the database. Having this functionality within the application has the following advantages - database design is simpler - database load is lower - fewer locking problems - testing data at application level is cleaner and more efficent than at the database. Any argument that implementing the implementing business logic ONCE at this database is more efficient ignores the use of 3GL libraries. I have worked on many projects with Oracle and MySQL, and I have always found implmenting business logic within the application more efficient. This does not mean triggers and procedures where not used, but complicating business logic that might cause a cascade of updates, inserts and deletes from many sources is always problematic. As MySQL stands now, I would recommend running a daemon process, written in Perl (or other language), that could process new data. This has the advantage of being future proof, and eliminates the potential problems that triggers cause due to data inserts from multiple sources. Simple create two table sets, one for loading data, and one for processed data. Have a perl daemon scan the load tables every 30s and process the data accordingly.

RE: Arithmetic Bug in 4.0.12/13-max
OK, I have been working on this for the last day. I read the manual sections that were recommended on floating point calculations and I am still seeing some weird things. I simply want to see if the average value of two columns named upper and lower (both are decimal(20,8) unsigned) is within the range of two decimal numbers I pass to the statement. The manual says in BIG CAPITAL LETTERS that you should NOT round and the only precise way of getting this to go is to do use the abs(a - b) some tolerance, such as .1. Having read that, I changed my code so that as follows: and ( ( abs(upper - 0.039) 0.1 ) or ( abs(lower - 0.037) 0.1 ) or ( ( (upper + lower) / 2 ) between 0.039 and 0.037 ) ) Which I assume would find anything where the upper column is .039, the lower column is .037 or the average between the columns is between .039 and .037. However, all I am returned is one record where the average ((upper + lower)/2) = 0.040 !!! I have plenty of records where the average is 0.038. Why is it not finding them?? Also, when my range is 0.038 - 0.038 so that the query looks like: and ( ( abs(upper - 0.038) 0.1 ) or ( abs(lower - 0.038) 0.1 ) or ( ( (upper + lower) / 2 ) between 0.038 and 0.038 ) ) It brings back ALL columns were the average is 0.038 AND it brings back records where the average is .040 and .036. In short, I am seeing exactly the OPPOSITE behavior I would expect from this. Any help would be much appreciated!

Possible way to do above comparison is to use ROUND() function on one or both columns. select (0.04 + 0.04)/2 = 0.040, round((0.04 + 0.04)/2, 3) = 0.040; You will get trues in right column for obvious reason. However most precise way is to do convert = to as a Range comparison 0.400+/- tolerance select (0.04 + 0.04)/2 BETWEEN 0.040 - 0.01 AND 0.040 + 0.01; This is well docummented in Manual: A.5.6 Solving Problems with No Matching Rows ... # If you are comparing FLOAT or DOUBLE columns with numbers that have decimals, you can't use '='. This problem is common in most computer languages because floating-point values are not exact values. In most cases, changing the FLOAT to a DOUBLE will fix this. See section A.5.7 Problems with Floating-Point Comparison. Read also whole A.5.7 Problems with Floating-Point Comparison I have worked around this by modifying my select statement to multiply each number by 1000, essential making each a whole number. When this is done, it work as it should. Yes as then MySQL uses integer arithmetics which is precise. Anyone have any ideas?

insert hang problem on Solaris 8
Hey there everyone.
I'm having a problem on a MySQL installation (vsn 4.0.12-standard) on
Solaris 8. I've got a few tables that get inserted into maybe 1000-1500
times a day. It seems to be pretty random, but I've seen three or four
times that the database just hangs on the insert.
SHOW PROCESSLIST shows this for the offending process:
| 77 | cpms | localhost | cpms | Query | 8076 | update | INSERT INTO
cpms_orders (order_id, add_timestamp) VALUES ('20030618-3', now()) |
I've still got it running, if anyone has any suggestions for a way to
get more debug data. The mysql software was built with gcc 3.2.2,
again, on solaris 8. If anyone's got any suggestions let me know!
Thanks! Unfortunately I'm gonna have to restart this sooner than later.
:/

RE: Triggers
Thanks to all. Simon's response outlines the direction I will be headed. KC [snip] The argument usually used by people looking for - triggers - functions + procedures - foriegn keys is the persuit of data integrity, and encapsulating business logic within the database. Whilst this goal is noble, it can be fully achieved within the application code, and not in the database. Having this functionality within the application has the following advantages - database design is simpler - database load is lower - fewer locking problems - testing data at application level is cleaner and more efficent than at the database. Any argument that implementing the implementing business logic ONCE at this database is more efficient ignores the use of 3GL libraries. I have worked on many projects with Oracle and MySQL, and I have always found implmenting business logic within the application more efficient. This does not mean triggers and procedures where not used, but complicating business logic that might cause a cascade of updates, inserts and deletes from many sources is always problematic. As MySQL stands now, I would recommend running a daemon process, written in Perl (or other language), that could process new data. This has the advantage of being future proof, and eliminates the potential problems that triggers cause due to data inserts from multiple sources. Simple create two table sets, one for loading data, and one for processed data. Have a perl daemon scan the load tables every 30s and process the data accordingly. [/snip] Much applause for your statements here Simon! It also makes the applications much more portable. Well said.

Loss of connection???
Hey gang... In my dbMove application I have the following. Ask SQL how many records I am moving- OK Display that amount - OK Delete all from corresponding MySQL table - OK Long pause, get a coffee, take a nap java.sql.SQLException: Communication link failure: java.io.IOException I read in a few places that this is thrown by MySQL. The question is, can this be corrected by changing the timeout? This would be odd since it seems that the error happens somewhere in the call AND I don't get a connection closed exception. The table in question has 44 million records in it. I have increased my timeout for this connection to over six hours. And the error occurs happens around 3-5mins later. We never return from the delete call...(i.e. It fails in the delete) and we never get a 'X number of rows affected' response. If this is being tracked by a transaction... how can we fix this?... I need transactions for other operations... so INNODB is critical... Anybody have any ideas?

Connection problems
Hi All, I hope someone can help with this connection problem. We have MySQL 4.0.12 installed on a W2K server and we are using the Connector/J version 3.0.7 driver to connect our Java applet to the database. The applet and the database are both on the same machine. mysql-connector-java-3.0.7-stable-bin.jar is in Java\j2re1.4.1_01\lib\ext The applet starts and makes the connection to the mysql database when running on localhost and everything works OK. Using a PC on the intranet or internet the applet starts but fails to make the database connection. The root user has been granted: grant all on dbname.* to [EMAIL PROTECTED] identified by 'password'; grant all on dbname.* to [EMAIL PROTECTED] identified by 'password'; and another user GRANT ALL ON dbname.* TO [EMAIL PROTECTED] IDENTIFIED BY 'userpassword'; but neither can connect to the database over the network. The user and root can access the database using mysql -u username (or root) -p and then entering the password. When attempting to connect from the PC on the intranet the trace gives the following: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at sun.applet.AppletClassLoader.findClass(Unknown Source) at sun.plugin.security.PluginClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at Database.connect(Database.java:666) at Database.testExists(Database.java:305) snip Attempting to connect over the internet the trace gives: java.sql.SQLException: Unable to connect to any hosts due to exception: java.security.AccessControlException: access denied (java.net.SocketPermission 192.168.1.90:3306 connect,resolve) at com.mysql.jdbc.Connection.createNewIO(Connection.java:1592) at com.mysql.jdbc.Connection.init(Connection.java:486) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:326) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at Database.connect(Database.java:667) snip Thanks in advance for any help on solving this problem.

segfault on startup after kernel change?
I recently changed my kernel (as noted in another message) to one that supports ACPI (for my laptop running RH9) and a couple other patches (I don't know all of them, one may have been the preemptive kernel patch). I've installed MySQL 4.0.12 from RPM's on the myslq.com site. When I start mysql using /etc/init.d/mysql start, I now get a 1024 segmentation fault: # /etc/init.d/mysql start # Starting mysqld daemon with databases from /var/lib/mysql /usr/bin/mysqld_safe: line 320: 1024 Segmentation fault $NOHUP_NICENESS $ledir/$MYSQLD $defaults --basedir=$MY_BASEDIR_VERSION --datadir=$DATADIR $USER_OPTION --pid-file=$pid_file --skip-locking $err_log 21 030618 08:00:57 mysqld ended I've checked the mysql log /var/lib/mysql/hostname.err but all it shows is this: 030618 08:00:57 mysqld started 030618 08:00:57 mysqld ended no realy information at all.

Database Design Question...
Hello... I am currently working on a User Account Management system. I am actually a Unix SA who is moonlighting at work as a MySQL DBA and web developer. I am learning a lot and enjoying the work, but I am severely lacking in database design fundamentals. I have created a couple very simple databases, but my two newest projects are getting more sophisticated. I was hoping for some DB design help with the following example... Let's say that I have users Mary, Joe, Frank, and Dan. I also have servers panther, cheetah, jaguar and lion. The data for each account that I want to maintain is UID, GID, home directory, and default shell. In designing a table or tables to handle this example what can I make as a primary key? My idea was to have a table named mary, with a row for each server, and each column would hold the data such as UID, GID, etc. This would mean that the primary key for each row would simply be the server name. By holding all of the data, including server name, in a single table, I am not sure how I would define a primary key. I couldn't use the user name or server name as there would be duplication. I suppose I could use a dummy numeric field that is auto-incrementing, but I am not sure how good an idea this is. I think I have read somewhere that you can actually use a combination of multiple columns as a primary key or index, but this is something I am obviously not familiar with. One other concern I have is regarding performance. The database work I have done so far has been dealing with relatively miniscule amounts of data. This database table however is going to contain information for about 80 servers with somewhere around 300 users per server on average. This is quite a large number of rows from my very limited experience. I don't want to come up with a poor table design that ends up causing problems down the line. Well, that's about all I can think of at the moment. I am sure that I will have plenty more questions as this progresses. Thanks again for the feedback.

RE: RAID hardware suggestions/experience
After testing a lot of different configurations (which was quite a headache), I came up with the following. First of all, for both speed and reliability, you will want SCSI. The list of reasons are quite long for SCSI, and as you are doing research on the subject, it is an obvious choice and I don't need to list them here. Get drives with 15K RPM, since disk seek time is a killer in database applications. U160 or U320 SCSI 3. With lots of cache on the drive (should be standard). I've found U160 to be sufficient, but U320 might be better for backups, etc. We do have U320 controllers now, to be ready for the future. Next, I found RAID 10 to be the best combination of redundancy and speed. It is not cheaper though. I have not tested hardware RAID (which is a shame -- it is a big hole in my experience), but use software RAID. Either way, position all the sets of mirrors such that each mirror set (2 drives) are on separate channels. This way, if your SCSI controller (or RAID controller) has a channel die, the whole array can still function (even with half of the drives down). Then stripe your (3-4) mirrors. Don't stripe too many. More sets to stripe increase performance, but syncing the rotations of many drives degrades performance. So there are diminishing returns. For our calculations, 3-4 mirrors were sufficient. Most of our RAID sets are six drives (3 stripe of 2 mirror). For one, we wanted more space and it has 8 drives (4x2). Don't forget to install spares at the same time. I like using external SCSI disk enclosures, so you can swap servers with less headache. -steve- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: Arithmetic Bug in 4.0.12/13-max
I figured it out. The between clause needs lower then upper, and I had upper then lower. The extraneous values I found must have been artifacts from the abs comparison, which was clearly not working anyway. I am just going to use the between clause. It seems to return the results I expect.

I read the manual sections that were recommended on floating point calculations and I am still seeing some weird things. I simply want to see if the average value of two columns named upper and lower (both are decimal(20,8) unsigned) is within the range of two decimal numbers I pass to the statement. The manual says in BIG CAPITAL LETTERS that you should NOT round and the only precise way of getting this to go is to do use the abs(a - b) some tolerance, such as .1. Having read that, I changed my code so that as follows: and ( ( abs(upper - 0.039) 0.1 ) or ( abs(lower - 0.037) 0.1 ) or ( ( (upper + lower) / 2 ) between 0.039 and 0.037 ) ) Which I assume would find anything where the upper column is .039, the lower column is .037 or the average between the columns is between .039 and .037. However, all I am returned is one record where the average ((upper + lower)/2) = 0.040 !!! I have plenty of records where the average is 0.038. Why is it not finding them?? Also, when my range is 0.038 - 0.038 so that the query looks like: and ( ( abs(upper - 0.038) 0.1 ) or ( abs(lower - 0.038) 0.1 ) or ( ( (upper + lower) / 2 ) between 0.038 and 0.038 ) ) It brings back ALL columns were the average is 0.038 AND it brings back records where the average is .040 and .036. In short, I am seeing exactly the OPPOSITE behavior I would expect from this. Any help would be much appreciated!

Re: transactions with php
If you're using a non-persistent connection, PHP will close the connection when the script terminates, and the MySQL server will roll back implicitly. For a non-persistent connection, the connection remains open and you may not see the rollback behavior your expect. I thought this was fixable now. A while back Monty said that changing users on a connection would reset the connection automatically. He was talking about the next version (which was several versions back of the 4 series). Resetting the connection (according to this theory) would set all the per connection variables to their default and rollback any non-committed transactions. My PHP Mysql extension is a bit hacked up (and I have more to do!), so I can't remember the default now. But I think it should add a 'change user' command when the page ends on any persistent connection. Change to a blank user. So in theory then, web pages would be safe for transactions. A really ugly hack (assuming a Mysql server version as described above) would be (in PHP) to connect persistently to mysql then change the user to a dummy, and then change the user to the one you want again. Doing this at the start of every page should then make it transaction safe. Can someone from MySQL confirm that changing users will reset the connection and rollback unfinished transactions? And starting in what version? -steve- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Database Design Question...
[snip] Let's say that I have users Mary, Joe, Frank, and Dan. I also have servers panther, cheetah, jaguar and lion. The data for each account that I want to maintain is UID, GID, home directory, and default shell. In designing a table or tables to handle this example what can I make as a primary key? My idea was to have a table named mary, with a row With the name mary, are you implying a separate table for each user? If so, that doesn't sound right. I think you should have three tables: (1) A table of users, with properties that depend on the user but not those that might vary with server; (2) A table of servers, with properties that are indepedent of users; (3) A table with primary key formed by a pair of foreign keys, one pointing at the user table, one at the server table. This table would have properties that depend on the user/server combination. (An example would be the shell, since presumably a user could have different shells on different servers.) for each server, and each column would hold the data such as UID, GID, etc. This would mean that the primary key for each row would simply be the server name. By holding all of the data, including server name, in a single table, I am not sure how I would define a primary key. I couldn't use the user name or server name as there would be duplication. I suppose I could use a dummy numeric field that is auto-incrementing, but I am not sure how good an idea this is. I think I have read somewhere that you can actually use a combination of multiple columns as a primary key or index, but this is something I am obviously not familiar with. One other concern I have is regarding performance. The database work I have done so far has been dealing with relatively miniscule amounts of data. This database table however is going to contain information for about 80 servers with somewhere around 300 users per server on average. This is quite a large number of rows from my very limited experience. I Nah, doesn't sound like much data to me. don't want to come up with a poor table design that ends up causing problems down the line.

Large Table Woes
Hey gang... sorry, I duped the subject of someone elses message... so I'm going to send this again In my dbMove application I have the following. Ask SQL how many records I am moving- OK Display that amount - OK Delete all from corresponding MySQL table - OK Long pause, get a coffee, take a nap java.sql.SQLException: Communication link failure: java.io.IOException I read in a few places that this is thrown by MySQL. The question is, can this be corrected by changing the timeout? This would be odd since it seems that the error happens somewhere in the call AND I don't get a connection closed exception. The table in question has 44 million records in it. I have increased my timeout for this connection to over six hours. And the error occurs happens around 3-5mins later. We never return from the delete call...(i.e. It fails in the delete) and we never get a 'X number of rows affected' response. If this is being tracked by a transaction... how can we fix this?... I need transactions for other operations... so INNODB is critical... Anybody have any ideas?

RE: Triggers
Just a couple of quick notes: 1. While I use PHP CLI for a lot of things (can we say cron?), it is not a sufficient replacement for triggers. What happens when someone is using the Mysql command prompt to alter data? Or using a non-PHP application? 2. While I agree that having application code rather than stored procedures is a much better bet for code management, it is only true if you are dealing with a **very simple system** such as a web site. There are whole new levels of complexity when the system includes a web site, in-house VB and Java applications, software from other providers (CRM, whatever), etc., all accessing the same data repository. In these cases, stored procedures, triggers, views, etc., are necessary for data integrity, and code management. Just a note: while the website this email is attached to is a complex web application, it is still a simple system. I don't mean to imply that websites are simple. Just the system (webserver database) is simple. -steve- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

What sort of throughput are you seeing in that setup? God, I can't remember anymore. I can run a test again though. If you have one you want me to run, just send it. We don't have other people's money to spend, so all our disks are U160 18GB 15K IBM. They were less than $100 each when we got them. They work great! We only care about throughput when we do a clean backup. Application performance is our measuring stick. Nothing like an FTS query on a big ass table to do a test of both simultaneously.

Segmentation fault using the C API
This is a rather long message but I am stuck and am really in a bind so I wanted anyone who might be willing to point me in the right direction to have the full picture. I recently installed MySql 4.0.13 on a Intel Linux box running Red Hat 9. I used the RPM that I found on the MySQL site. I had to remove the existing MySQL 3.23 installation prior to installing 4.0.13, which was kind of a pain but I got it to work, although it ended up in /usr/bin instead of /usr/local, as the MySQL manual suggests to put it. I then created a database, created some tables and populated them manually using sql statements. I am able perform all db operations as expected. Prior to installing MySQL using the provided RPM for my system, I also downloaded, unziped and untarred a binary distribution in /usr/local, as per the MySQL reference manual. Once I got the RPM install to work I never removed this. I thought this turned out to be a good thing as I could not locate the lib directory to link against from the RPM install so I used /usr/local/mysql-4.0.13-pc-linux-i686/lib to link against instead. In a separate directory I installed a copy of the source distribution so that I could mess around with the C API w/i affecting the good version of 4.0.13 that I installed using the RPM and already have populated manually with data. I proceeded to write a short '*.c' program that would accept command line args (database, user password) and then connect to the database using mysql_real_connect(), print a message to the console indicating it had connected successfully, then exit using mysql_close(). I saved the source file in the same directory that the example programs that came with the source distribution (../mysql-4.0.13/client) are stored. I compiled this program using the following (note I used the library that came with the RPM that I installed earlier: gcc -g -o mysql_connect_test mysql_connect_test.c -I ../include -L /usr/local/mysql-standard-4.0.13-pc-linux-i686/lib -lmysqlclient -lnsl -lz The program compiled fine but when I ran it I get a segmentation fault. Thought it might have been programmer's error so I reviewed my code and it is not. I then compiled 'insert_test.c', a program that came with the source distribution and it to compiled fine using the above make line. When I ran this executable it also seg faults. Is there something I am missing. Is it not OK to use the libraries from the standard RPM install? Thanks for anyone help in advance.

Re: Database Design Question...
On 18-Jun-2003 NIPP, SCOTT V (SBCSI) wrote: Hello... I am currently working on a User Account Management system. I am actually a Unix SA who is moonlighting at work as a MySQL DBA and web developer. I am learning a lot and enjoying the work, but I am severely lacking in database design fundamentals. I have created a couple very simple databases, but my two newest projects are getting more sophisticated. I was hoping for some DB design help with the following example... Let's say that I have users Mary, Joe, Frank, and Dan. I also have servers panther, cheetah, jaguar and lion. The data for each account that I want to maintain is UID, GID, home directory, and default shell. In designing a table or tables to handle this example what can I make as a primary key? My idea was to have a table named mary, with a row for each server, and each column would hold the data such as UID, GID, etc. This would mean that the primary key for each row would simply be the server name. By holding all of the data, including server name, in a single table, I am not sure how I would define a primary key. I couldn't use the user name or server name as there would be duplication. I suppose I could use a dummy numeric field that is auto-incrementing, but I am not sure how good an idea this is. I think I have read somewhere that you can actually use a combination of multiple columns as a primary key or index, but this is something I am obviously not familiar with. One other concern I have is regarding performance. The database work I have done so far has been dealing with relatively miniscule amounts of data. This database table however is going to contain information for about 80 servers with somewhere around 300 users per server on average. This is quite a large number of rows from my very limited experience. I don't want to come up with a poor table design that ends up causing problems down the line. Well, that's about all I can think of at the moment. I am sure that I will have plenty more questions as this progresses. Thanks again for the feedback. 300 * 80 =24,000 rows --this is _NOT_ a lot. At first, I'd use just one table: srvr varchar(32) NOT NULL, login varchar(32) NOT NULL, uid smallint unsigned NOT NULL DEFAULT 1000, gid smallint unsigned NOT NULL DEFAULT 1000, gecos varchar(128), sh varchar(32) NOT NULL DEFAULT '/bin/sh', home varchar(64), ... more fields ... primary key (login,srvr)) A next refinement would change the 'srvr' field to: srvr tinyint unsigned and create a 'server' table: id tinyint unsigned AUTO_INCREMENT, // last octet of ip ? name varchar(64) NOT NULL, primary key (id)) That'll make it easy to rename servers. The table(s) could be populated very easily with a couple of shell, Perl, and/or awk scripts. YP/NIS would come in handy as well. You'd loop on each distinct server name --request a ypxfer of the passwd map, then suck it into your table. Regards, -- Don Read [EMAIL PROTECTED] -- It's always darkest before the dawn.

That is an unsupported use of an AUTO_INCREMENT column, which is intended to hold only positive integer values. Not negative values, and not zero. Hmm, the manual is not very consistent with that: AUTO_INCREMENT will not work with negative numbers.; Its possible to create a row where the AUTO_INCREMENT column is 0 by explicitly setting the column to 0 with an UPDATE statement); and some examples using UNSIGNED. (You will find, for example, that if you run CHECK TABLE on your table, it will complain about 0 values in an AUTO_INCREMENT column. Also, dumping and restoring the table will change your zero values.) Damn! Glad you told me that! I had missed it in the manual. By dumping, you mean BACKUP, mysqldump, SELECT * INTO OUTFILE or all of them? The manual is also not explicit on that. I've to say (not to complain) this looks wrong. Definitely unexpected.

Hi all, Is it possible to crypt the passwords on MySQL. If yes, how does it work, and how is it to be implemented. Any link would be great. Thank you.

RE: How to have AUTO_INCREMENT ignoring 0?

(without messing with the code, of course) No. Using NULL to get the next sequence number is good enough for me and I use quite a lot 0 for special purposes (default record values,...) That is an unsupported use of an AUTO_INCREMENT column, which is intended to hold only positive integer values. Not negative values, and not zero. Hmm, the manual is not very consistent with that: AUTO_INCREMENT will not work with negative numbers.; Its possible to create a row where the AUTO_INCREMENT column is 0 by explicitly setting the column to 0 with an UPDATE statement); and some examples using UNSIGNED. (You will find, for example, that if you run CHECK TABLE on your table, it will complain about 0 values in an AUTO_INCREMENT column. Also, dumping and restoring the table will change your zero values.) Damn! Glad you told me that! I had missed it in the manual. By dumping, you mean BACKUP, mysqldump, SELECT * INTO OUTFILE or all of them? The manual is also not explicit on that. I'm not sure what happens with BACKUP TABLE, but I suspect that it doesn't alter the values in an AUTO_INCREMENT column because it operates using direct file copy operations. Any method that dumps table contents and them reloads them record by record certainly will change 0 values in an AUTO_INCREMENT columns. This includes reloading output produced by mysqldump or SELECT ... INTO OUTFILE. I've to say (not to complain) this looks wrong. Definitely unexpected. (A dump/restore modifying data) The manual recomends using NULL over 0 as the magic value to use to get the sequence number. I had some hopes this could mean some way to cancel the magic effect of 0 (hence my post) or some future plans to drop it. Any chances? I don't know, but I'd say it's unlikely. You're probably better off using another column to indicate whether or not records are special.

RE: Can we crypt passwords on MySQL
There is a PASSWORD('your_clear_text_password_here') function you can use
wherever you define a new password. See the manual for more.

Re: Can we crypt passwords on MySQL
Hi,
Using PASSWORD function to crypt password is not recommended, it's mainly
used for internal mysql password encryption.
Prefer using MD5/SHA1 functions to encrypt a password.
Regards,
Jocelyn

RE: RAID hardware suggestions/experience
A lot of table scans do to bitmasked column values. So SELECT * FROM search_table where AND colN 4; Such that the above query will not utilize a key. I was told at the last convention that mySQL had some good ideas on allowing indexes for bitwise (arithmetic) columns but they are not quite there yet. It's a hard problem I can only think of a way by having every possible bit in an index but then that makes the index useless. ---Original Message- --From: Steven Roussey [mailto:[EMAIL PROTECTED] --Sent: Wednesday, June 18, 2003 12:59 PM --To: 'Mysql' --Subject: RE: RAID hardware suggestions/experience -- -- --2 x 2.8 GHZ Xeon --4 GB of RAM --5 15K SCSI Drives --ICP SCSCI RAID control card with 1 Gb of ram on it. --I just bought 30 of these boxes to build out my mysql farm for close to --400-600 queries a second with 60 connections a second of mix read / --writes. -- -- --What kind of queries are you doing?

Upgrade from mm to Connector/J under tomcat
I've googled, but haven't got a hit, so please excuse if this has been covered many times before. System: linux, (debian for what it matters) tomcat 4.0 java 1.3.1 mysql 2.23.x Curently we are using the older org.gjt.mm.mysql.Driver drivers. We support many different sites which use .jsp pages and bean. If we move the org.gjt.mm.mysql.Driver drivers into the local lib directories WEB-INF/lib/.. and compile the beans with the driver. Can we upgrade one context at a time to Connector/J or must we shut down the server and upgrade them all at the same time? Anyone done this? William R.

Re: Innodb error
John,
what Linux kernel version you are running? Did the first crash occur because
of the same assertion failure?
The InnoDB tablespace is probably corrupt and it asserts in purge or insert
buffer merge.
You can try starting with
innodb_force_recovery=4
in the [mysqld] section of your my.cnf. You can try to determine how
widespread the corruption is by running CHECK TABLE ... on your tables.
Then dump your tables and recreate the whole tablespace.
MySQL-4.0.14 will have the page checksum fixed. Then we will get more
information whether this kind of corruption originates in the file system.
It might also be an ordinary bug in InnoDB. It asserts in copying of records
to another page because a record does not fit though we have calculated it
should fit.
I have now added diagnostic code to 4.0.14 which will print hex dumps of the
pages if the assertion fails again.

This could be because you hit a bug. It is also
possible that this binary
or one of the libraries it was linked against is
corrupt, improperly built,
or misconfigured. This error can also be caused by
malfunctioning hardware.
We will try our best to scrape up some info that will
hopefully help diagnose
the problem, but since we have already crashed,
something is definitely wrong
and this may fail.

Prior to this, I was doing 'mysqldump -A ...' and
mysql crashed. After rebooting the server I can get
mysql running again, but most queries show 'connection

the queries work after the client automatically
reconnects. 'mysqlcheck [-r] ...' dies with
'connection lost'.
Please help!
