        Oracle uses DATE/TIME format, maybe your DATE record isn't exactly '21-aug-96 00:00' but '21-aug-96 00:01' for example ?

        When you use the '=' operator ORACLE translates '21-aug-96' as you query, '21-aug-96 00:00' which doesn't match using '=' but match with LIKE.

        I hope it'll help you !
