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

this issue is because of low storage space availability of a particular drive(c:\ or d:\ etc.,), release some memory then it will work.
