Rule Property

Diese Funktion wird in zukünftigen Versionen von Microsoft SQL Server nicht mehr bereitgestellt. Verwenden Sie diese Funktion beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.

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.

Syntax

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);
HinweisHinweis

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.

Hinweise

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