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);
