Im running  Windows7 / Mysql5.1
According to various pages the error log should be in: /usr/local/mysql/bin/mysql
However, this partial path name is flawed. When I use "search everyting", I dont even have a folder name usr... Can someone provide a complete and working path to the MySql ERROR log?

That's a Unix/Linux path to the mysql binary ;)

You done have /usr on a windows platform, that is for  a unix based OS..

Do a search for my.cnf or my.ini in there it will tell you that file the  location of the log files, they are normally in the data directory...

You are looking for sothing similar to :
datadir="D:/xampp/mysql/data"
log_error="mysql_error.log"

Open in new window



Or use :

SHOW VARIABLES LIKE '%log_file%';

Open in new window

That's why I pasted a link to the MySQL 5.1 Installation Layout on Microsoft Windows.

You should have a file in the /data directory mysql_error.log

The error i can see, but i need to know the exact MYSQL code that generated the error. Im using Mydac from Devart to send Mysql code from Delphi and in this case I cant see exactly what code is sent - so i want to solve this from the "other side" and see exactly what code Mysql receives.
