You should be able to repair it. If the repair fails then it's a sign that the table is very corrupted, you have no choice but to restore it from backups. If you have other systems (e.g. non-production with same software versions and schema) with an identical table then you might be able to fix it with some hackery (copying the frm an MYI files, followed by a repair). In essence, the trick is to avoid getting broken tables in the first place. This means always shutting your db down cleanly, never having it crash and never having hardware or power problems. In practice this isn't very likely, so if durability matters you may want to consider a more crash-safe storage engine. share|improve this answer answered Mar 12 '10 at 7:4

When I try to select all records, it exhausts the system's memory and I get an error about memory exhaustion back. When I try to use the MySQL LIMIT and select 1,000 records, the error in the title is returned: General error: 126 incorrect key file Incorrect key file for table '/tmp/#sql_27e6_0.MYI'; try to repair it' What's the best course of action to export all of the data in this table? Why is it returning an error when only trying to pick 1,000 records?

Why would it be eaten up trying to select 1,000 and what are my alternatives? –Noah Matisoff Mar 24 '15 at 20:28 1 You're doing an ORDER BY. It has to sort the entire table of 2 million records before giving you the first 1000.
