Hi,
I'm working on a database program and I noticed that when I'm doing queries with tables that have TEXT/BLOB columns, MySQL will use temp tables and use filesort. I'm not entirely sure when and how this happens, but are there cases where MySQL does not use filesort when there are BLOB/TEXT columns? Like if the sort column is type of VARCHAR() with an index?
