Rule Property
The Rule property identifies a data integrity constraint, implemented by a Microsoft® SQL Server™ 2000 database rule and bound to the referenced column or user-defined data type.
Applies To
| Column Object | UserDefinedDatatype Object |
Syntax
object.Rule [= value]
Parts
object
Expression that evaluates to an object in the Applies To list
value
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);
Note 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.
Remarks
Setting the Rule property offers an alternate method for binding SQL Server rules to columns.
