I assume that the columntype of id_pr_data_feed is something like "unsigned int" or similar ?
If so, numeric that is, then its incorrect to wrap the value around '.
What happends is that mysql is forced to cast all values into stringtype before they then can be evaluated.
So if you change your "WHERE id_pr_data_feed='49'" into "WHERE id_pr_data_feed=49" I think you query will be blazing fast...
