ReferencedKey Property
未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。
The ReferencedKey property returns the name of the PRIMARY KEY or UNIQUE key constraint implementing the primary key referenced by a foreign key.
語法

Parts
- object
An expression that evaluates to an object in the Applies To list
Data Type

Read-only
Prototype (C/C++)
HRESULT GetReferencedKey(SQLDMO_LPBSTR pRetVal);
[!附註]
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.
備註
The ReferencedKey property returns a value for Key objects referencing foreign key definitions only. If the Type property of the Key object is SQLDMOKey_Foreign, the Key object references a foreign key definition.
