UnbindFromDatatype Method

  • 發行項

未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能，並計劃修改目前使用此功能的應用程式。

The UnbindFromDatatype method breaks the binding between a Microsoft SQL Server default or rule and a user-defined data type.

語法

object
.UnbindFromDatatype(
Datatype
, [ FutureOnly ] )

Parts

  • object
