Where can I find the MySQL transaction log?
Solution 1
If you turned on - mysql can track binary log, which contains all the modifications (to be clear - it contains the queries that had changed something).
But anyway, it is useless if you do not have the initial dump, which precedes the binlog turning on. Also i suppose if you made the dump and turned on binlog - you would not ask such question :-S
Solution 2
Short answer: not by default.
In order to have accurate logging results, you need to have started the server in binary logging mode first, using the parameter --log-bin=your-file-name
. It then creates a binary log file {your-file-name.seq} where seq
is a sequence number for subsequent log files (recommended to put your file name there, with explicit directory location).
More information on the MySQL site explaining all the details: https://dev.mysql.com/doc/refman/5.7/en/binary-log.html
Solution 3
If you're using MySql on Windows, there's a file located in C:\Program Files\MySQL\MySQL Server 5.0\data
(assuming a C: drive for the installation target and MySql version 5.0), that is called %COMPUTERNAME%.log that contains the commands that have been executed.

Does MySQL keep a transaction log and if so where could I find it?
A number of rows have mysteriously been deleted from a table and I want to try and see how and when it occurred.

php-b-grader almost 14 yearsI've checked PHPMyAdmin and there are statistics for binary logs which look like they've been running for over 1 week... Is there a config that will point me to the file location (on a linux system)

zerkms almost 14 yearslog-bin=mysql-bin -- it is the sample line from my home server config file. so i have mysql-bin* files within my data directory. btw, as i said, if you have no the dump that has been taken just before you turned on binlog - then binlogs are useless. also - you should look at query log (if you have them) as Amber offered.
