Hiya Tyler As everyone else has suggested, I do too. Read the MySQL-manual. Not from the start to the end, but the parts that you need. I'd look up the syntax for SELECT and then find out what is possible to do with it. I'll also recommend you an article about MySQL/PHP which was the one getting me started (And I'm making a living of it actually!) : http://hotwired.lycos.com/webmonkey/programming/php/tutorials/tutorial4.html A book worth reading would be : "MySQL" by Paul DuBois, which covers almost every aspect of the MySQL-DB ...

Replication question
Hi there, My situation is like this: I have a local server behind a firewall. On the outside I have a webserver. I want the local server to act like a master for replications, and the external server to act like a slave. This way I can make the changes on my database directly on the local server. But the problem is that I can't connect to the local server from the external server because of the firewall. Is there a way where I can have the external server acting as a slave, but where the master a doing the connection stuff? in other words : The local server can do a connection to the external server, but the external server can't open a connection to the local server.

User table problem
Hi, I have a problem with mysql users. I can`t connect to database with any user when I use password. Eg, if from the command line I try to connect like mysql -h myhost -u myuser -p and then on the password line write my password, it gives permission denied... If I try to go in just without password, I can get in, but this I don`t have lots of permissions. The problem exists in all users, including root. The passwords have been set, that`s for sure and it even used to workany ideas what might be wrong?

Okey, now, I have installed it on D:\MySql coz my WINNT4 is installed on this drive, amI in need to install it as recommended the default path on c, or I can freely install it on D? will there be any changes for that if I install it on D while working with mysql ? Second, I wonder about the steps for installing, what shall I type ? mysqld --install? if yes, then I face a problem after typing D:\mysql\bin\mysql, a msg comes up saying : cant connect to host SERVER1? so where will be the problem ? no mysql shell comes and I can't work with mysql... Is there any other things should be done for working properly with mysql ? I noticed the winAdminSql, that sign that comes in the bar looks like the light traffic, is there must something to be done there or not to play with it ???

RE: mysqldump hangs
FYI, I tested MySQL 3.23.36 with the same setup as below.

After about a minute, MyTable.backup stops growing in size (according to ls -l). 'top' shows that mysqld has over 99% of cpu. Note that this box is a dedicated db server, and no other major processes are running. Nothing changes after 10, 20, 30 minutes. After killing mysqldump, mysqld is still at 99% cpu. I then kill -9 mysqld, and cpu % goes to zero. I have similar behavior when I try to create an index on this table. For example, if I type mysql create index MyIndex on MyTable ( MyField ); 'top' shows that mysqld is at 99% cpu, and the index is still not done being built after 30 minutes (the identical data is on a linux box, and the index takes 3 minutes to build.

Re: Need examples of companies using mysql
Unless you're going to have a LOT of users accessing a HUGE database, the system you've outlined below will be overkill (do you have any current usage statistics ? Are you using the system (is it an E450 ?) for any other applications/processes ?). It would be, if it was dedicated to mysql :) One of their concerns is load testing, which we haven't done a lot of yet. I'm confident it'll hold up, I am a little worried it may generate enough load to annoy them, but worse comes to worse we can set up a dedicated box. -- ___ __ ____ _ _ _ _ / __)( )( ) /__\( \/ )( ___) ( \( )( ___)(_ _) \__ \ )(__)( /(__)\\ / )__)) ( )__) )( (___/(__)(__)(__)\/ ()()(_)\_)() (__) I/O, I/O, it's off to work we go... - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Performance question
Hi,
I've got a question 'bout the number of number of writes a MySQLserver can
handle in a second. I've written a program which contains the following
code:
typedef struct {
MYSQL * connection;
char * database;
} con;
int resolvequery(char * vraag, MYSQL_RES toReturn, int affected, int
control) {
MYSQL_RES * result;
MYSQL_ROW row;
int state,counter;
char * query;
char * db;
MYSQL * connect;
int * temporal;
connect = standardcon.connection;
db = standardcon.database;
state = mysql_real_query(connect, vraag, 1024);
if (state != 0) {
printf(mysql_error(connect));
return 1;
}
if((strncmp(vraag,"SEL",3)==0)||(strncmp(vraag,"SHO",3)==0)
||(strncmp(vraag,"DES",3)==0))
{
result = mysql_store_result(connect);
affected = mysql_num_rows(result);
toReturn = *result;
}
else
affected = 0;
return 0;
}
And when I call this procedure 50 times/second (from one client)
or 100 times/second (two clients at the same time) it stores all the data
without generating an error, but immediatly when I start a third client it
crashes with the usual segmentation fault. In case you need it, the calls
are made from this function:
CORBA::Short i_DBM_impl::storeData(const DINA::t_Table table,
const char * e) throw(CORBA::SystemException)
{
int state;
char * mission;
MYSQL_RES temp;
mission = (char *) malloc(256 * sizeof(char));
sprintf(mission, "INSERT DELAYED INTO %s VALUES
('%s',CURRENT_TIMESTAMP())",
(char *) table.name, e);
cout mission endl;
if (resolvequery(mission,temp,state,0)==0)
return 1;
else
return 0;
}
So is it possible that some buffer is full or something when more than 100
inserts in second are requested?? What can I do to adjust the performance or
did I make other mistakes?? I'm using mysql Ver 9.38 Distrib 3.22.32, for
pc-linux-gnu (i586) on Debian Linux machine.
Please can you also mail to me ([EMAIL PROTECTED]) and not only directly
to the list (I'm receiving the index-version and else I've to wait too long
:-)
Greetings,
Raf

Re: MySQL 3.23.36 is relased
Everyone: why did the volume of the source distribution jump from something like 5+ MB to 10+ MB ? This is not likely from a bugfix.

Mirroring/Failover for MySQL (Was Need examples of companies using mysql)
Hi Steve, To achieve mirroring, MySQL can be run in a master/slave replication ring with two servers (look up replication in the manual). That way you can split reads and writes over both servers and get better read performance, and also more resilience. The way to achieve transparent failover is to have a load-balancer such as LVS (http://www.linuxvirtualserver.org). You can have two (again for failover) 1U rackmounts running LVS - the hardware can be something as low as 486 class. The LVS takes connections and redirects them to each of the MySQL servers in round-robin fashion. If one of the MySQL servers dies, it will be taken out of the pool until it is back up again. The way replication works in MySQL, if one of the servers dies, the other server will keep a binary log which is used to catch the downed server up when it comes back online. The only drawback with dual-master configuration is that unique IDs cannot be guaranteed if generated from the database - for instance, if an INSERT is processed at the same time by both masters. Therefore, unique IDs must be generated in the client with the use of mutexes.

Probably because you need to redirect your output into the file AFTER all the options. Rewrite your command like this: mysqldump --flush-logs --add-drop-table -u root -p markloky shuncheong /backup/shuncheong.sql See if that works. The way you had it written, you weren't passing the -u and -p options to mysqldump. So, mysqldump was connecting as an unprivileged user.

daylight savings
I have a problem with my time (now()) in mysql running on WIN98 (also in WIN NT). After the daylight savings, the time on the WIN machines is changed by 1 hour. But still the now() function returns a time as if there is no change for daylight savings. Timezone parameter is currently set to Central Standard Time. Where do I set in mysql configuration for daylight savings switch.

FP exception in sql/sql_select.cc on osf1/4.0f + gcc 2.95.2
Description:
On mysql-3.23.33 on Tru64 4.0f, using gcc 2.95.2 (any optimisation
level), sql_select.cc will raise a FP exception at line 1785 of
sql/sql_select.cc, quoted here:
: if (tmp best_time - records/(double) TIME_FOR_COMPARE)
At the time that the exception occurs, the values are:
tmp = 3
best_time = DBL_MAX
records = 1
This code works properly on virtually all other os's, so after
some amount of digging, it became apparent that it was a compiler
issue of some form. Eventually, I reduced the problem down to
this bit of code:
--
#include stdio.h
#include float.h
int main(void)
{
volatile double a = 1,
b = DBL_MAX;
a = b - 1;
return 0;
}
--
The volatile statement is just to ensure that the variables a and b
are stored in memory rather then being optimised away into
registers.
If you compile this with gcc, a FP exception will occur when you
attempt to subtract 1 from b (=DBL_MAX). This is caused by the fact
that Alpha's FP handling is pretty damn weird, to say the least.
This behaviour can be "fixed" by using the "-mieee" compiler option
in gcc.
How-To-Repeat:
Stuff some non-trivial select statements into a mysql server
compiled in this way, and it will crash very quickly.
Alternatively, try compiling/running the demo code given above.
Fix:
Add "-mieee" to CXXFLAGS and CFLAGS.

Re: Error message: [Incorrect information in file: './ts1/tbl_status.frm']
Might the NFS dependence be a problem?
Yes, it could , particularly if you do not have --skip-locking as
mysqld startup or if some other processes access the files.
Regards,
Sinisa
Hi Sinisa,
What does "some other processes access the files" mean? Are you thinking
like automated system backup software, or my own database client
accesses?
"configure" apparently placed -skip-locking into safe_mysqld, so I have
always been running with this option on Linux.
Since Saturday AM,
- I moved all databases ("/var") onto my /tmp disk,
- forced table operations to occur 12 times a day,
and cannot replicate the original problem, so stability has returned.
So, either:
1. should not be using -skip-locking on NFS,
2. NFS implementation + Linux should not be used (i.e., continue
using a local disk).
Do I really need -skip-locking on a Linux 2.2.12 kernel?
= I rolled up a fcntl() test fragment, and it seems to work with
2 unrelated processes:
stuff
lk.l_type = F_WRLCK; /* advisory lock on entire file. */
fcntl(fd, F_SETLK, lk)
stuff
lk.l_type = F_UNLCK;
fcntl(fd, F_SETLK, lk)
I assume "configure" knows best about my system's fcntl() lock
implementation and that it would do the correct thing? Should I
try an NFS usage mode w/o -skip-locking, or will this create
other more serious errors on Linux?
Thanks for the pointers.
Silvio

Re: backup mysql using crontab
Probably because you need to redirect your output into the file AFTER all the options. Rewrite your command like this: In which shell? In SunOS /bin/sh, or in bash, the shell strips out the redirection, and the program sees what's left. It doesn't matter where the redirection is; it can even be before the call to mysqldump. --Pete mysqldump --flush-logs --add-drop-table -u root -p markloky shuncheong /backup/shuncheong.sql See if that works. The way you had it written, you weren't passing the -u and -p options to mysqldump. So, mysqldump was connecting as an unprivileged user.

Help!! New Win32 mySQL User
I am a newbie to the mySQL world and am having some difficulties with it. I am running a Win2K network (Win2K Pro, Win2K Adv. Server) using TCP/IP. I loaded mySQL on both a server and a workstation. I was able to get the server going (mysqld-nt --install, net start mysql), and was able to log into the server from my workstation (mysql.exe -h webserver -u administrator). I was able to see the databases (show databases;). I went out to the web and started poking around for a GUI client program. I loaded and tested a whole bunch of them, but my favorite was mySQL Front. I was able to load it, log in to the "Test" database, create tables, and everything else. I loaded a couple of others, but didn't find anything I liked better. I decided to go with mySQL Front. When I retried mySQL Front, I could no longer access the database. I was still able to access it, however, from mysql.exe (mysql.exe -h webserver -u administrator). I bought the Paul DuBois book, and started combing through it. I found something that sounded like it made sense - permissions. I tried shutting down the server, and then restarting it using "mysqladmin --skip-grant-tables", but the NT Command Processor just hangs when I issue this command. Now I have this thing so messed up, that I cannot log into the server at all except locally. What am I doing wrong??? Thanks!

mysqld silently quits on date-related query
Description:
We just upgraded our Sun Ultra 60's to Solaris 8, and in so doing,
We upgraded MySQL from 3.22.32 to 3.23.36 (installed from source package).
The new version of the server quits with status 1, and no error log
output, when we do the following query:
select * from foo where fooDate = '2001/1/2'
(or any date). It also happens with "... = '2001/1/2'", ie., any query
on a date.
Here's a dump of the simple table:
# MySQL dump 8.13
#
# Host: localhostDatabase: allenhdb
#
# Server version3.23.36-log
#
# Table structure for table 'foo'
#
CREATE TABLE foo (
fooDate date default NULL
) TYPE=MyISAM;
#
# Dumping data for table 'foo'
#
INSERT INTO foo VALUES ('2001-01-02');
We re-installed 3.22.32, and it works fine. This problem also existed
with 3.23.35 when I tried that.
It's hard to believe that this is a bug in MySQL, more likely some
configuration problem or OS compatibility issue (?). Either way, it's
pretty serious for us. Maybe we just did something wrong.
How-To-Repeat:
The Description section pretty well describes how to duplicate the
problem, at least on our machines. Hopefully you'll see the same thing.

Importing
I'm tring to import a text file to mysql. The problem I am having is that the mysql database is located on a seperate server from the web site. I can do query's and inserts but I can not get the mysql server to grab a txt file from the web server and load it into the database. I have been using the following code: $query = "LOAD DATA LOCAL INFILE '$tmp\\$file1_name' "; $query .= "INTO TABLE usr FIELDS "; $query .= "TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' (name,email,login,active,defaultpw)"; The site is located on an NT server and the database is on a UNIX server. Not sure if that matters or not. Any help would be great.. Ian

About the upper limit of data storage...
Hi all, Some one told me that the upper limit of MySql data storage is 1 Gb of data. As I am new so I am not sure of this. If any gurus of MySql can please tell me about it, it would be great. Regards Dp Balcom Systems Technologies, Inc. (408)468-6608
after changing master-host in my.cnf, slave remained committed to old master.info
i initially had a master-host=A defined in my.cnf.
later i changed that to master-host=B.
i was mystified when i got a connection error:
Slave thread: error connecting to master:Host 'dumbo.pobox.com' is not allowed to
connect to this MySQL server(0), retry in 60 sec
i spent much time prodding and poking before i realized that
due to the preexisting master.info, the slave was trying to
connect to the old master A, not the new master B.
i propose the following patch to make the error string more
verbose: it indicates what host, user, and password are in
use.
it may need to be edited to be NULL-safe --- if password is null, etc.

Re: Converting Access to MySQL
Luis, This is an easy one. Go here ftp://ftp.informate.co.nz/pub/ and download one of the scripts, the instructions are in the script. It will create a text file that has the sql commands needed to create and fill your mySQL tables with your Access info. You can exec the script from the mySQL prompt. -bryce on 4/2/01 3:52 PM, Luis at [EMAIL PROTECTED] wrote: Hello to all, I was wondering if anyone could help me out with a little project i have going.

Selecting certain fields
Hi all, I suppose this is more of a feature request for the mysql developers. I have a user who only has read access to a few columns of one table. This table is very large so that it means that the columns, this user has access to, is still quite large. If I do a SELECT * FROM... returns an access denied error. Is it possible to change it so that it returns all the columns that this user has access to, rather then the error. Stating 50 or so columns in a SELECT statement each time, is rather time consuming.

SQL : multiple SELECT and missing rows.
Hello Guys, I have a (very simple?) SQL question. I'm more then sure the answer to it is whether "just do this..." or "It's impossible man, how could you even get that into your mind..." I have this database design: (it's more complex of course, but you get an idea) Table 'accounts': +---+--++ | ID| type | since | +---+--++ | 1 | P| 1999-08-01 | | 2 | F| 1999-11-06 | | 3 | S| 2000-07-05 | | 4 | P| 2001-01-01 | +---+--++ Table 'addresses': +---+--+--+-+ | ID| city | pref | country | +---+--+--+-+ | 1 | Shibuya-ku | 13 | JP | | 2 | Nakano-ku| 13 | JP | | 4 | Toyonaka-shi | 27 | JP | +---+--+--+-+ As you can see, the main data is in 'accounts', the 'addresses.ID' is UNIQUE and corresponds to 'accounts.ID'. The fact is that not every account has an address registered with it. I need to list ALL the accounts in this order: +---+--+-++---+ | ID | Type | City | Country | Since | +---+--+-++---+ Therefore I am trying to do it with the following query: SELECT accounts.ID AS ID, accounts.type AS Type, addresses.city AS City, addresses.country AS Country, accounts.since AS Since FROM accounts, addresses WHERE addresses.ID=accounts.ID ORDER BY accounts.ID ASC LIMIT 10 ; And, this selects me IDs 1, 2 and 4. 3, obviously, is not here because there's no such address.ID as stated in my WHERE clause. Can anyone suggest me how do I SELECT ALL of the accounts having simply NULL on 'addresses.*' when there's no such row, instead of 'loosing' the whole 'account' row? I sure know how to do it using two queries, still, I wonder if one single query can do this job. Where do I miss the logic?

But, perhaps (gasping) that causes instead of a single scan through the indeks table, 1,264 seeks from the index file to the data file to the index file... etc? Still, your data set is surely small enough to fit all in disk cache. But perhaps there's also a thousandfold increase in the work done by mysqld at some point during this query? (Grasping again.) In terms of query-optimization, it seems (logically, not necessarily the same as SQLese :) that you really want to join indeks with itself to find indeks.foto_id's which have a word='foo' and a word='bar', and then join that result set with f. Perhaps there's a better way to optimize the query / indexes to reflect that? -- Hank Leininger [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: SQL : multiple SELECT and missing rows.
You want to use the "LEFT JOIN" syntax. A general outline would be: SELECT [your fields] FROM accounts LEFT JOIN addresses ON addresses.ID = accounts.ID WHERE ... ORDER ... LIMIT ... This would select all addresses.ID's, including those where accounts.ID is NULL. -Kevin --On Tuesday, April 03, 2001 10:41 AM +0900 Maxim Maletsky [EMAIL PROTECTED] wrote: Hello Guys, I have a (very simple?) SQL question. I'm more then sure the answer to it is whether "just do this..." or "It's impossible man, how could you even get that into your mind..." I have this database design: (it's more complex of course, but you get an idea) Table 'accounts': +---+--++ | ID| type | since | +---+--++ | 1 | P| 1999-08-01 | | 2 | F| 1999-11-06 | | 3 | S| 2000-07-05 | | 4 | P| 2001-01-01 | +---+--++ Table 'addresses': +---+--+--+-+ | ID| city | pref | country | +---+--+--+-+ | 1 | Shibuya-ku | 13 | JP | | 2 | Nakano-ku| 13 | JP | | 4 | Toyonaka-shi | 27 | JP | +---+--+--+-+ As you can see, the main data is in 'accounts', the 'addresses.ID' is UNIQUE and corresponds to 'accounts.ID'. The fact is that not every account has an address registered with it. I need to list ALL the accounts in this order: +---+--+-++---+ | ID | Type | City | Country | Since | +---+--+-++---+ Therefore I am trying to do it with the following query: SELECT accounts.IDAS ID, accounts.type AS Type, addresses.city AS City, addresses.country AS Country, accounts.since AS Since FROM accounts, addresses WHERE addresses.ID=accounts.ID ORDER BY accounts.ID ASC LIMIT 10 ; And, this selects me IDs 1, 2 and 4. 3, obviously, is not here because there's no such address.ID as stated in my WHERE clause. Can anyone suggest me how do I SELECT ALL of the accounts having simply NULL on 'addresses.*' when there's no such row, instead of 'loosing' the whole 'account' row? I sure know how to do it using two queries, still, I wonder if one single query can do this job. Where do I miss the logic?

NEW MAKE BUG? sigcontext.h
Doing a "make" on the newest MySQL stable 3.23.36 source tarball - on a stock Cobalt RaQ3 (Linux 386) which I've installed MySQL on many times before.

MySQL Security
Dear sir or madam
MySQL user's account is not related to user's account on Linux System, so they can
be different.
My problem is that I use perl DBI to interact MySQL server as belows:
--
use DBI;
$dbh = DBI-connect("DBI:mysql:DatabaseName","$user","$password");
---
So $user and $password can be known by any users in Linux system because they are
written in text format and DataBase can be changed or updated by other users in Linux
system easily by using Perl DBI. Is there any way to prevent Database from being
changed? Millon of thanks

Re: Importing
I believe the problem is with your use of "LOCAL". This is telling the server to try to load the file on the computer it is running on. If this is not where the file is on the computer running mysqld this could explain why it cant read it. Try removing the "LOCAL" part, you also might want to enable compression depending on how fast the link between the two computers are. ryan I'm tring to import a text file to mysql. The problem I am having is that the mysql database is located on a seperate server from the web site. I can do query's and inserts but I can not get the mysql server to grab a txt file from the web server and load it into the database. I have been using the following code: $query = "LOAD DATA LOCAL INFILE '$tmp\\$file1_name' "; $query .= "INTO TABLE usr FIELDS "; $query .= "TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' (name,email,login,active,defaultpw)"; The site is located on an NT server and the database is on a UNIX server. Not sure if that matters or not. Any help would be great..

Taing:
I use php3 to do my apps for web applications and chown the /www/ files to
www.www and chmod them to 0750 with the server running as user www.
This prevents any users from viewing the source code: i.e. the /www/ files that
contain your perl scripts. This might be an option for you if the perl user can
run as www.www and you can run those perl scripts as user www within the web
context.
This is just how I do it, but, others might have different implementations.
Best Regards,
Van

How to recover from accidental 'drop database mysql'
Greetings: I accidently dropped (my thunderous stupidity!!!) our mysql database. There were a few usernames and other databases. I expected hell to break loose (it may still happen!), but strangely enough, I noticed that I was still able to login, probably because mysql server caches usernames, passwords, etc ?? I quickly backed up the remaining databases using mysqldump. I did a make install to update the database and everything still seems ok. Now, anyone know if there is any way to create or repair my existing mysql database with the information that is currently cached in the server ? For example, if I do "show databases", I see all the databases that should exist, but when I do a "select * from mysql.db", I only see the "test" database!. Any ideas will be gratefully appreciated and accepted ! --== Sent via Deja.com ==-- http://www.deja.com/ - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
