SHOW GLOBAL STATUS LIKE ‘Created_tmp_disk_tables’.
Everytime I run that query through phpmyadmin another disk based temp table is created.
Is there a way to prevent it?
Edit : Looks like doing anything in phpmyadmin is creating temp disk tables.
I don’t think it is so… I have now tested on 3 servers (2 of them MySQL 5.1, one is 5.0), I have run the command several times and number of temp tables did not increase. Which MySQL version do you have? On which platform? Anyway, if it would be true, I would say it is a bug, because showing a variable should not need to create a temp table.
So it seems that some other queries which are running on your server are creating those disk temp tables and increasing your count.
