Rule Property
Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The Rule property 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

.Rule [= value]
Parts

Hinweis: |
---|
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. |
