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++)
