ReferencedKey Property
未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能,並計劃修改目前使用此功能的應用程式。
The ReferencedKey property returns the name of the PRIMARY KEY or UNIQUE key constraint implementing the primary key referenced by a foreign key.

---|
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.
