How do you fix a MySQL “Incorrect key file” error when you can't repair the table?

Question

I\'m trying to run a rather large query that is supposed to run nightly to populate a table. I\'m getting an error saying Incorrect key file for table \'/var/tmp/#sql

Answer 1

REPAIR TABLE tbl_name USE_FRM;

Command only run when MySQL 'Storage Engine' type should be 'MyISAM'

Hope this helps
