BindRule 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 BindRule method implements Microsoft SQL Server rule binding and unbinding for columns and user-defined data types.

语法

object.BindRule(RuleOwner,RuleName,Bind [,bFutureOnly])

Parts

• object
  Expression that evaluates to an object in the Applies To list.

• RuleOwner
  String identifying the database user owning the bound rule.

• RuleName
  String identifying the bound rule by name.

• Bind
  TRUE or FALSE as described in Settings.

• bFutureOnly
  TRUE or FALSE. This is an optional parameter that applies only to the UserDefinedDatatype object.

Prototype (C/C++)

HRESULT BindRule(SQLDMO_LPCSTR RuleOwner,
SQLDMO_LPCSTR RuleName, BOOL Bind, BOOL bFutureOnly);

Settings

When Bind is TRUE, the rule named is bound to the column or user-defined data type referenced.

When Bind is FALSE, any rule is unbound from the referenced column or user-defined data type. The RuleOwner and RuleName properties are ignored.

注意
When you use the UserDefinedDatatype object, the bFutureOnly parameter is available in C/C++ applications.

注释

The BindRule method of the Column or UserDefinedDatatype objects, and the BindToColumn and BindToDatatype methods of the Rule object, associate a SQL Server rule with a user-defined data type or column.

The BindDefault method does not cause a check of existing values when a new rule is indicated for a column or user-defined data type.

Applies to:

Column Object

UserDefinedDatatype Object
