Re: Selects are slow when blob field?

OK I'll look into combining indexed fields, depending on my queries.

I didn't do anything about the default storage engine, so I gather it's MyISAM. Your explanation matches what I thought is happening, thus accounting for the long queries. Is there a different storage engine that is more efficient with blobs? My example is contrived because in reality all queries need the blob data, so moving the blob to a join table would not bring me any benefits. I'm looking for quicker handling of the blob data.

Thanks,

Normand
