Rule Property

この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。

The Ruleproperty identifies a data integrity constraint, implemented by a Microsoft SQL Server database rule and bound to the referenced column or user-defined data type.

構文

object.Rule [= value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    A string that identifies a SQL Server rule by name

Data Type

String

Modifiable

Read/write for the Column object. Read-only for the UserDefinedDatatype object.

Prototype (C/C++)

HRESULT GetRule(SQLDMO_LPBSTR pRetVal);
HRESULT SetRule(SQLDMO_LPCSTR NewValue);
注意注

SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

説明

Setting the Rule property offers an alternate method for binding SQL Server rules to columns.
