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 DataSource property provides a value for the OLE DB initialization property DBPROP_INIT_DATASOURCE. Initialization properties are set for the provider when an attempt is made to connect to the OLE DB data source referenced by the LinkedServer object. For more information about values for the DataSource property, see the OLE DB provider documentation.
