BindToDatatype Method
后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。
The BindToDatatype method enables a default or rule on the user-defined data type specified.
语法
object.BindToDatatype(DatatypeName, [ FutureOnly ] )
Parts
object
Expression that evaluates to an object in the Applies To list.DatatypeName
String specifying an existing user-defined data type by name.FutureOnly
When TRUE, binding does not cause a check of columns existing and defined using the data type. When FALSE (default), existing values are checked for agreement with the rule.
Prototype (C/C++)
HRESULT BindToDatatype(
SQLDMO_LPCSTR DatatypeName,
BOOL bFutureOnly = FALSE);
