Re: mysqld, mysqld-nt, mysqld-debug
Steve (n) Martin! if you want apache and mysql (and possibly PHP for scripting) AND you want all 3 to run at once then d/l and implement with XAMP there are alot of XAMP specific bells and whistles that are installed that get in the way of tuning your MySQL and tuning your Apache installations so my advice is if you just want to use Mysql standalone dont use XAMP but start mysql with mysqld as suggested Well, that's your opinion. But I think for beginners is XAMPP the best basis. Everything else you can later still wish to change. Once is a fact, I wanted no discussion on the pros and reignite XAMPP.

Varuna, obviously it doesn't make much sense, to specify the my.ini location in my.ini itself.

Re: Changing the location of my.ini and the order option files are read
Armin I did what you said, now I understand what you say that there is no sence in what I wanted to do.But I gave these commands as follows But it did not work.What I want is to specify a configuration file which is placed in the WINDOWS directory.The commands I ran C:\NET STOP MySQL C:\mysqld-nt --remove C:\mysqld-nt --install MYSQL --defaults-file=\c:\WINDOWS\my.ini\ Service successfully installed. C:\net start mysql System error 2 has occurred. The system cannot find the file specified.

Re: Any easier way to compare mysql schema of 50 databases?!
Hi, I was also going to go down this route some time back, but then when I looked at it, it's pretty simple how it works and you can do the same thing yourself for free. Take a dump of both servers (mysqldump or via MySQL Administrator) of the databases in question, then use WinMerge (for free) to compare the dump files and (optionally) create a 3rd file which is a result of merging the 2 by choosing the changes you want to keep. I've used this method plenty of times to synchronise changes between servers, some that concern 000s of rows of data. Granted you cannot do this with PostgreSQL as those dumps tend to be in binary format, but it works well for MySQL backups. WinMerge: http://www.winmerge.org/ Andy D.

Re: Access Rights ?
Hi Sachin, MySQL is capable of logging all queries to a log file, see http://dev.mysql.com/doc/refman/5.0/en/query-log.html. This includes connections, disconnections and executed SQL statements - no coding needed! If you want this information imported into a database table, a couple of hours and a few cups of coffee will allow you to write a simple PHP script (or C program for the hard-core developers) to read this file and write the details of each record to a database table.

C api - mysql_list_fields
I'm probably being a bit stupid - but I'm trying to determine (in code) the
length of the string in the schema for a given table.
So - for example :
create table a (
blah char(20)
)
I want to return '20', but I'm getting '60' when I use mysql_list_fields..
(Always seems to be 3x longer that I'm expecting)...
Am I missing something ? (or should I just divide by 3!!)
Heres an example :
#include stdio.h
#include stdlib.h
#include mysql.h
MYSQL conn;
int main(int argc,char *argv[]) {
// run with username port as arguments
char *tabname=a;
char *db=test1;
char *u;
char *p;
MYSQL_RES *result;
MYSQL_FIELD *field;
if (argc!=3) {
printf(usage : %s username password\n, argv[0]);exit(2);
}
u=argv[1]; p=argv[2];
mysql_init(conn);
if (!mysql_real_connect(conn, NULL,u,p,db,0,NULL,0) ) {
fprintf(stderr,
Failed to connect to database: Error: %s\n,
mysql_error(conn));
exit(2);
}
result = mysql_list_fields (conn, tabname, NULL);
field = mysql_fetch_field (result);
printf(Field =%s Type=%d Length=%d\n, field-name,
field-type, field-length);
}
Thanks in advance...

Re: Access Rights ?
Hi Sachin, What version of MySQL are you running? I believe --log-output was only added in 5.1 which is why a 5.0 server would fail to start with this option set. I think the relevant option should also be log-output in my.cnf / my.ini (e.g. log-output = FILE, TABLE.) It looks like 5.1 greatly improves on the functionality you're looking for, including the native ability to write the logs to a database table, however it's currently more efficient to write to a file than it is to a table. See http://dev.mysql.com/doc/refman/5.1/en/log-tables.html for more information. Andy Sachin Gaikwad wrote: Alrite guys. I added log=/tmp/logfile in /etc/my.cnf and removed log = FILE, TABLE.

But before that I am not able to find this logfile for general queries. I started my server like this: $/etc/init.d/mysqld start --log=logfile --log-output=/tmp Meaning log file will be in = /tmp/logfile $mysql mysql select * from whowhatwhen; xx xxx x mysql So this query should exist in logfile. But I am not able to see this logfile in /tmp itself. What am I missing ?

Hi all, I am newbie using MySQL. I want to log each client request to database server. I thought when server checks access rights of user(client) will be good place to log all access/read/update requests. If somebody knows where exactly this is done in source code, I will get a real kick start. Right now I am browsing through the source code through cscope to find out this. Any help in this regard is appreciated.

Take a dump of both servers (mysqldump or via MySQL Administrator) of the databases in question, then use WinMerge (for free) to compare the dump files and (optionally) create a 3rd file which is a result of merging the 2 by choosing the changes you want to keep. I've used this method plenty of times to synchronise changes between servers, some that concern 000s of rows of data. Granted you cannot do this with PostgreSQL as those dumps tend to be in binary format, but it works well for MySQL backups. WinMerge: http://www.winmerge.org/ Andy D.

If you can afford to spend a few dollars to get the right tool, you want to get DB Comparer for MySQL from the folks at EMS: http://www.sqlmanager.net/en/products/mysql/dbcomparer This tool will compare the schemas of 2 MySQL Databases and allow you to selectively choose which changes to make in order to synch to the master or the target DB. I've been using the PostgreSQL version of this tool for many years and just recently started using their MySQL one. -- Dante -- D.
