If SET ANSI_NULLS is OFF than Null = Null evaluates to True. I don't know about any settings that could make Null = '' to evaluate to true. Aanyway it has nothing to do with Sql Server version (7 or 2000) but with it default or otherwise settings/configuration.

>>Here's how you query for nulls and empty string

* Null
>>SELECT * FROM MyTableName WHERE MyFieldName IS NULL
>>* Empty varchar filed
>>SELECT * FROM MyTableName WHERE LEN(MyFieldName)=0
