MySQL incorrect key file for tmp table when making multiple joins

Question

I don\'t come here for help often but I am pretty frustrated by this and I am hoping someone has encountered it before.

Whenever I try to fetch records from a table

Answer 1

Only increase the file tmp, because mysql doesn't have space in it, for queries...

mount -o remount,size=[NEW MAX SIZE HERE] tmpfs /tmp
