Re: Count massively faster than select on same query, why?!?!

Ok, solved this problem now.

We removed the blob column from the table, creating a new table for this blob alone and inserting a foreign key in the orignal table, and the select now works reliably fast (well, <2 seconds, which is a massive improvement as opposed to 120/240 secs) The blob was a text64

This improvement was achieved without changing the indexes,types or query structure. So maybe mysql can't handle blobs so well.

Thanks for your help.
