属性值

类型：System.Boolean
A Boolean value that specifies whether the check constraint is a system-named check constraint. By default, the value is unspecified.If True, the check constraint is system-named.If False (default), the check constraint is not system-named.

注释

注意注意

For check constraints based on the UserDefinedTableType object this property is always true because the user-defined data type is automatically system-named.
