Property Value

Type: System.Boolean
A Boolean value that specifies whether the ANSI_NULL_DEFAULT database option is active.
If True, user-defined data types default to allowing NULL values.
If False (default), user-defined data types default to not allowing NULL values.

Remarks

This option lets the user control the database default nullability at a database level.

This option can also be changed by using the Transact-SQL ALTER DATABASE statement.
