Valeur de propriété
Type : System.Boolean
A Boolean value that specifies whether the ANSI_NULLS_ENABLED database option is active. If True, comparisons to null values equate to false.If False (default), comparisons to null values equate to true.
Notes
This property specifies whether any comparison to a null value equates to a NULL value. For example, A SELECT statement using WHERE column_name <> NULL returns zero rows even if there are non-null values in column_name
Cette option peut aussi être modifiée à l'aide de l'instruction Transact-SQL ALTER DATABASE.
