This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
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.
HRESULT GetRule(SQLDMO_LPBSTR pRetVal); HRESULT SetRule(SQLDMO_LPCSTR NewValue);
|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.|
