I have a table similar to this: Id int identity primary key ImageData image OtherField varchar(20) etc If I execute this against a record with a null imagedata: SELECT Id FROM MyTable WHERE Id=12345 AND ImageData IS NULL then the query more or less times out however SELECT * FROM MyTable WHERE Id=12345 returns a result immediately. This query has been in place for a long time prior to moving to 2005. Can anyone suggest a reason why including an image or text column in the query criteria does not work in 2005 (it is happening in other tables also). DBCC CheckTable returns no errors.
