Setting that affects "NOT IN" predicate?

    I had a co-worker mention there was a setting in SQL Server 2000 that would affect the results of a NOT IN subquery. I have looked through all the BOL and the internet but have not found anything. The only thing that I have found is related to results dealing with a NULL.

    Does anyone know of a setting, database or server or sql statement, that would change how SQL returns the results?

    Thanks,

    Maybe the are referring to potentially use NOT EXISTS instead of NOT IN ?

    They mentioned that this setting would affect whether the "NOT IN" would return the correct results or not. I will have to determine if they might have been talking about the NOT EXISTS.
