주의
By default, Microsoft SQL Server creates columns that do not accept NULL when the user does not explicitly declare the ability to accept NULL. Further, SQL Server returns TRUE when evaluating the expression NULL = NULL. These default behaviors are nonstandard.
If AnsiNulls is TRUE, new columns accept NULL by default and any comparison of NULL to any other value, including NULL, returns NULL.
The AnsiNulls property affects the way in which NULLs are handled for the user's connection only and overrides any database-specific settings for column creation and NULL comparison.
