Reading the MySQL Manual

I was asked the question today, “How do I show the details of a Stored Procedure in MySQL. The SHOW PROCEDURE ‘name’ didn’t work.”.

The obvious answer was SELECT ROUTINE_NAME,ROUTINE_DEFINITION FROM INFORMATION_SCHEMA.ROUTINES, given I like to use the INFORMATION_SCHEMA whenever possible. This lead me to think was is the corresponding SHOW command. A quick manual search got me to SHOW CREATE PROCEDURE.

What was interesting was not this, but the list of other SHOW commands I didn’t know. I did not know about SHOW MUTEX STATUS, SHOW OPEN TABLES and SHOW PROCEDURE CODE for example.

It pays if you have free time (who ever has that), to re-read the manual, or at least a detailed index regularly. I’m sure there are plenty more helpful tips out there. Now just what does the output of these new commands really do, and does it really help. If only I could get commands to the stuff I really want.

    Yo Ronald! Next version of innotop has a nice feature to make SHOW MUTEX STATUS (and the commands that replace it in later versions) a lot easier to use ;-) SHOW OPEN TABLES is already there of course.
