Copying to tmp table on disk (1 reply)

Dear All,

I am using MySQL 5.1.47 (64bit) on CentOS 5.5. I have INNODB tables and one table has got more than 10 million records in it. When I query the table on the index column then I can see something "Copying to tmp table and Copying to tmp table on disk" in show full processlist; Please let me know how to avoid these temp tables manipulations?

Regards,
Asad.
