DataSource Property

后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The DataSource property specifies the OLE DB data source part of initialization properties used by a provider to locate a data store.

语法

object.DataSource [=value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    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);
注意注意

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.
