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. |
注释
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.
