DatabaseName 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 DatabaseName property represents the name of an existing Microsoft SQL Server database. It constrains SQL Server Agent service alerts or directs execution of SQL Server Agent job steps.
语法

| 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
SQL Server Agent alerts can be fired when a specified system message is generated by an action occurring on an instance of SQL Server. Alerts based on messages can be constrained so the alert is only fired when the action occurs within a single database. For example, system message 1105 is generated if a database is full and can accept no more rows. An Alert object representing this alert for the Northwind database has a MessageID property value of 1105 and a DatabaseName property value of Northwind.
Each step of a SQL Server Agent job can execute in a specified database. Setting the DatabaseName property of a JobStep object directs the execution of the represented step.
