Database 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 Database property identifies a Microsoft SQL Server database.

语法

object
.Database [=value]

Parts

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

• value
  A string that specifies a SQL Server database by name

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetDatabase(SQLDMO_LPBSTR pRetVal);
HRESULT SetDatabase(SQLDMO_LPCSTR NewValue);

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.

备注

For a Login object, the Database property identifies the default database for the SQL Server login referenced.

For a Backup or Restore object, the Database property identifies the source or target database for a Transact-SQL BACKUP or RESTORE statement. The property is a required element and must be set before the SQLBackup method of the Backup object or the SQLRestore method of the Restore object is called.

Applies To:

Backup Object	Restore Object
Login Object
