属性值

类型:System.Boolean
A Boolean value that specifies whether ISO NULL handling is enabled in the DDL trigger. ISO NULL handling requires that any comparison to a NULL value equates to a NULL value.If True, ISO NULL handling is enabled and comparisons to null values equates to False.If False (default), ISO NULL handling is disabled and comparisons to null values equates to True.

注释

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
