Re: MySQL on Linux
Just to be complete, linux does have limitations depending upon limitations of the file-system, and the kernel. All modern filesystems (XFS, EXT3, ...) all allow files over a terabyte is size.

Displaying string including Kanji characters
When I use multi-byte code (especially UTF-8) with data including Kanji (Japanese kanji character) and execute SELECT from mysql client command, the vertical lines(|) of output table aren't aligned as straight lines and the output doesn't look like a table. When I use SJIS code, the problem of sheared line doesn't occur. This is because the display width and the byte number of data always match. To display multi-byte code, not only the count of character and byte, but the display width is also very important. The width of Kanji in EUC-JP, SJIS, and UTF-8 is double the width of alphanumeric characters. As far as I could see, the result of functions involving display, such as LPAD and RPAD, doesn't seem to take the display width of Kanji into account.

mysqld_multi kills socket from previous Daemon
Hello all, I would like to run diverent MySQL-Daemons on the same Linux machine, so I use mysqld_multi to start the different processes. The Config looks right to me, I have different Database Directorys, Pid-Files, Ports, IDs usw. and different Socket-Files and all over it seems to work. But! as soon as I start the sekond Daemon my Socket-'File' from the first one, who ist started at the boot time (like RedHat Config), disappears! Both Daemons are running still fine, but the first one without a Socket. I have to connect over the TCP Port. The same happens if i stop the first Daemon and then start it with mysqld_multi. The Socket is here, untill I start the next Daemon with mysqld_multi. Has anybody a Idee where I can look and find a way to keep my Sockets ??? Before I say good by, I would like to apologies about the bat sentens construction and the writing mistakes in English!

GMT-DST time conversion in (My)SQL ?
Hello, i have a table that contains datetime entries which are stored in GMT. Now I would like to convert these datetime values in a select statement to local time. I first thought of someting like this (in germany DST starts at 2004-03-29 02:00:00 and ends 2004-10-31 03:00:00 this year. The difference from GMT to local time is 1h and from GMT to local DST time 2h): SELECT if(datetime between 2004-03-29 02:00:00 AND 2004-10-31 03:00:00, DATE_ADD(datetime, INTERVAl 2 HOUR), DATE_ADD(datetime, INTERVAL 1 HOUR) ) FROM table ... ... This basically works but of course only if the select statement return rows with datetime entries in the year 2004. Eg if there are rows with a datetime field of 2003-xx-xx then the statement from above will fail. Is there any more general way to do such a timezone conversion or is the only solution to let the application to this work that reads the MYSQL output?

One immediate question I have is regarding getting aggregate information. For example, the SHOW DATABASES command would be an example of something I would get from the SQL Server data dictionary table, sysdatabases. It appears that MySQL has no such mechanisms, and that you must rely on many of the SHOW commands. In the case of databases, it works great, but what about other objects? For example, if I want to see all indexes in my sales database? Or do I have to loop through each table with the SHOW INDEXES command? That's one example of what I'm talking about.

Re: Connecting 2 MySQL databases: how?
* Steijn, B.S. I would like to make a connection between 2 databases in MySQL that are on the same server. If you by connection mean to join tables from the two databases on the same server, you can do that. The purpose is that a class X in database A uses a class Y in database B by a foreign key. Thus, the table in B can be re-used by other databases which will make my databases more efficient. Right. I've already thought of a solution like FOREIGN KEY c_id REFERENCES A.customer(c_id)ON DELETE CASCADE but I think this will not work. Is there any other solution to do this? Right, this will not work. But this is a foreign key constraint, you don't need a constraint to make a join work. -- Roger -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

4.0.12 to 4.0.18
I upgraded from MySQL 4.0.12 to MySQL 4.0.18 last night and found some oddities this morning. Apparently some of the varchar data being input into certain tables had carriage returns: \n in the data. This was an accidental thing, but on 4.0.12, the \n was ignored when matching on that record. However, now in 4.0.18 it seems to include that when determining matches. For example: select * from table where record='abc'; used to match both 'abc' and 'abc\n' but now only matches 'abc'. Did I miss something in the change history that said this should now happen or is this an undocumented difference? Thanks, Brian Stanton Systems Administrator, Belo Interactive

RE: Corrupted relay log
Here's what I did to fix it... Excert from MySql Manual... When you back up your slave's data, you should back up these two small files as well, along with the relay log files. They are needed to resume replication after you restore the slave's data. If you lose the relay logs but still have the `relay-log.info' file, you can check it to determine how far the SQL thread has executed in the master binary logs. Then you can use CHANGE MASTER TO with the MASTER_RELAY_LOG and MASTER_RELAY_POS options to tell the slave to re-read the binary logs from that point. This requires that the binary logs still exist on the master server. I performed these steps... Read info form relay-log.info file. Mysql: Slave Stop; Mysql: Change master to master_host = '192.168.1.10', Master_User = 'name', Master_Password = 'pass', Master_log_File = 'get this from relay-log.info', Master_log_pos = get this from relay-log.info; Mysql: Slave Start; Does anyone see a problem with this method?

Re: Why can't I use an AS value in the WHERE clause.
Good point. I was focused on the question of using the alias to restrict results, so I left the function in the SELECT part. As you say, in this query, that would just give a useless column of '1's, so you might as well leave it out. In that case, though, the alias question is moot. That is, it doesn't really make any difference whether you put the condition in the WHERE or HAVING clause. On the other hand, we can imagine a query where we want to see a calculated result and use it to screen which rows are returned. Then using the alias in the HAVING clause is the way to go. For example, something like SELECT *, unix_timestamp()-unix_timestamp(last_seen) AS Last_Active FROM wifi_table HAVING Last_Active 600; Michael Adam wrote: Mike, I see what you're saying `active` was the alias name not an actual column. Ironically I was using a HAVING clause because I agree with that last post. Mike, why keep the `IF` statement? You're really saying give me all the records where this expression is true. Why not just move the expression in the `IF` to the HAVING clause? So take my old statement and ditch the where clause. You'll get: SELECT * FROM wifi_table HAVING unix_timestamp()-unix_timestamp(last_seen) 600; A little easier on the eyes no? Cheers, Adam On Apr 6, 2004, at 9:42 PM, Michael Stassen wrote: Adam, That won't work. Daevid doesn't have a column named active. Nor does he have to do the math twice.

If you can type 'mysql_config' at the command line and get an answer like: Usage: /usr/local/bin/mysql_config [OPTIONS] Options: etc The perl DBD module should be able to find and use this program to configure itself.

Its call rewinding the replication thread. -- DVP -Original Message- From: Jeff McKeon [mailto:[EMAIL PROTECTED] Sent: Thursday, April 08, 2004 10:43 AM To: [EMAIL PROTECTED] Subject: RE: Corrupted relay log Here's what I did to fix it... Excert from MySql Manual... When you back up your slave's data, you should back up these two small files as well, along with the relay log files. They are needed to resume replication after you restore the slave's data. If you lose the relay logs but still have the `relay-log.info' file, you can check it to determine how far the SQL thread has executed in the master binary logs. Then you can use CHANGE MASTER TO with the MASTER_RELAY_LOG and MASTER_RELAY_POS options to tell the slave to re-read the binary logs from that point. This requires that the binary logs still exist on the master server. I performed these steps... Read info form relay-log.info file. Mysql: Slave Stop; Mysql: Change master to master_host = '192.168.1.10', Master_User = 'name', Master_Password = 'pass', Master_log_File = 'get this from relay-log.info', Master_log_pos = get this from relay-log.info; Mysql: Slave Start; Does anyone see a problem with this method?

Re: Corruption and my.cnf
I've experienced more corruption lately on my main site since I moved to my
own server running 4.0.17max. The site is very busy (60GB a month) and the
tables are large. I didn't have this level of problems on the rental server.
What are the variables to look into regarding why my tables are getting
corrupt? Is this a my.cnf issue? Is this a memory issue? Is this a hard
drive issue? Is this a too many connections issue?
Looking at my dmesg output..
end_request: I/O error, dev 03:42 (hdb), sector 52228450
hdb: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
hdb: read_intr: error=0x40 { UncorrectableError }, LBAsect=56276830, high=3,
low=5945182, sector=52228450
Is it possible this is related to my MySQL table corruption issues? There
are more of these in the file.

disabling backslash as an escape character in strings
Is there a way to disable the use of the backslash as an escape
character in strings? I need to use an application that's designed to
work on any database server supporting ANSI SQL. When it generates SQL
insert/update queries, it doesn't escape backslashes in strings, because
the ANSI SQL standard doesn't require backslashes to be escaped.
So to insert the value \, the application generates the following query:
INSERT INTO (test) VALUES('\');
Which causes an error in MySQL because it thinks the \ is an escape
character and the string is not closed.
If I modify the application to escape backslashes by replacing \ by \\,
it works with MySQL, but with other databases that don't interpret the
backslash as an escape character, it inserts two backslashes instead of one.
What could I do to tell MySQL it should interpret strings in the
standard way?
I tried starting mysqld in ANSI mode (mysqld-max-nt --ansi) but it
doesn't solve the problem.
I would also prefer a per-connection way to fix this, is there an option
I can set when connecting that won't affect other connections? I also
have other applications using the same MySQL server, some of which are
designed specifically for MySQL, so they may escape backslashes in the
MySQL way and switching the whole server to ANSI mode would break them.
I'm using MySQL 3.23 but I'm willing to upgrade to the latest 4.0x if it
can solve this problem.

Re: disabling backslash as an escape character in strings
Are you using a high level library such as Perl::DBI? If so, you should run
all your strings the quote method. That will quote it properly for each
database you connect to. If you are connecting to all the databases yourself
using custom code, I would recommend you find some database neutral libraries
and go from there.

You need to add the directory which contains mysql_config to your path. Adding to your PATH isn't difficult, but the method depends on your shell. You can find your shell with echo $SHELL I noticed that on my installation the 'mysql_config' is in '/usr/local/mysql/bin' directory whereas you have indicated that it should be in '/usr/local/bin' directory! Please clarify!! /usr/local/mysql/bin is fine. With tcsh, you can add this to your path with set path=($PATH /usr/local/mysql/bin) With sh or bash, you should be able to add this to your path with export PATH=$PATH:/usr/local/mysql/bin Either way, you should probably also add this to the appropriate shell startup file, so mysql is always in your path. You can check your path with echo $PATH Two more questions: (1) Since I have done partial installation, would it hurt if I re-do the entire Perl instalation or start from the command where the errors were encountered? You didn't break anything, you just didn't succeed in adding the module. Just go back into CPAN and try again. I'd suggest perl -MCPAN -eshell install Bundle::DBI install Bundle::DBD::mysql Installing the bundles will make sure you have everything you need. As you've already installed DBI, you'll already have most of what the bundles contain, and CPAN is smart enough not to reinstall what you already have. (2) I also have two Client MySQL servers (which connect to master MySQL server for data). Do I also need to install Perl on these Client MySQL Servers? I'm not sure what you mean by Client MySQL servers. Do you mean machines which need the mysql client to connect to the machine running the mysql server, or do you mean machines which will run the mysql server as slaves to the master server? In any case, you can run the mysql server and client without perl. On the other hand, a number of the helper apps in /usr/local/mysql/bin are perl scripts. Of course, you will need to install perl on any machine where you want to use perl to connect/manipulate your mysql data, and perl is handy to have around in general.
