Rule Property
この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。新規の開発作業ではこの機能を使用しないようにし、現在この機能を使用しているアプリケーションは修正することを検討してください。
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.
構文

.Rule [= value]
Parts
- object

- value

Data Type

Modifiable
Read/write for the Column object. Read-only for the UserDefinedDatatype object.

HRESULT SetRule(SQLDMO_LPCSTR NewValue);
メモ : |
---|
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. |
