Valeur de propriété

A Boolean value that specifies the whether newly created columns allow nulls by default or not. If True, new columns created allow null values by default. If False (default), new columns create do not allow null values by default.

Notes

This property is mutually exclusive of the AnsiNullDefaultOff property. An exception occurs if you attempt to set both properties to True simultaneously. In SQL Server Management Objects (SMO) the default nullability of a new column can be overridden by setting the Nullable property of the Column object. In Transact-SQL the default nullability of a new column can be overridden by adding the NULL or NOT NULL clause to the CREATE or ALTER TABLE statement.
