Rule Property
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.
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);
Note
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.
Remarks
Setting the Rule property offers an alternate method for binding SQL Server rules to columns.
