ListBoundDatatypes Method
未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能,並規劃修改目前使用這項功能的應用程式。
The ListBoundDatatypes method returns a SQLObjectList object that enumerates the user-defined data types to which a rule, or default, is bound.
語法
object.ListBoundDatatypes()asSQLObjectList
Parts
- object
Expression that evaluates to an object in the Applies To list.
Prototype (C/C++)
HRESULT ListBoundDatatypes(
LPSQLDMOUSERDEFINEDDATATYPELIST* ppList);
Returns
A SQLObjectList object that contains 0 or more UserDefinedDatatype objects.
備註
A SQL Server default or rule cannot be dropped when bound to a SQL Server object.
For the Default or Rule object, you can use the ListBoundDatatypes method to enumerate user-defined data type bound, and then use the Name property of UserDefinedDatatype objects returned and the UnbindFromDatatype method of the object to remove bindings.
A SQL Server default or rule can be bound to a column. Use the ListBoundColumns and UnbindFromColumn method to remove bindings on a column.
