How to flush data from mysql.slow_log table in mysql?

Hi i am working on MySQL version 5.5, can somebody please help me to clear/flush data from mysql.slow_log tables in mysql ?

Solution

  • If you are on linux

    > mysql -uroot -p
> enter your password
> use mysql;
> delete from slow_log;

    It will give you an error that you can't lock log tables. Work around is, run the following queries:

    SET GLOBAL slow_log= 'OFF';
RENAME TABLE slow_log TO general_log_temp;
DELETE FROM `general_log_temp`;
RENAME TABLE general_log_temp TO slow_log ;
SET GLOBAL slow_log = 'ON';

    Taken from "DELETE old rows from Mysql General Log Table"

    Update:

    You can truncate the table like TRUNCATE mysql.slow_log as mentioned by Renato Liibke
