DataSource Property
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The DataSource property specifies the OLE DB data source part of initialization properties used by a provider to locate a data store.
Sintassi
object.DataSource [=value]
Parts
object
An expression that evaluates to an object in the Applies To listvalue
An OLE DB provider-defined string
Data Type
String
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetDataSource(SQLDMO_LPBSTR pRetVal);
HRESULT SetDataSource(SQLDMO_LPCSTR NewValue);
[!NOTA]
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.
Osservazioni
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.
