备注

In Microsoft SQL Server 2005 Notification Services, you can specify the name of the instance database. This database can be a new or existing database. If the database already exists, Notification Services creates instance objects in the specified schema of the existing database. If the database does not exist, Notification Services creates a new database with the specified name and creates instance objects in the specified schema.

ms145358.note(zh-cn,SQL.90).gif重要提示:
The specified database must be using 90 compatibility mode.

If you specify a database name, you should specify a unique schema using the SchemaName element. All instance objects are created in that schema.

If you do not specify the database name and schema name, Notification Services creates a new database with the name instanceNameNSMain, where instanceName is the value of the InstanceName element, and creates all instance objects in the dbo schema.

When you delete an instance of Notification Services, Notification Services will delete the instance database only if Notification Services created the database. Otherwise, Notification Services only deletes the instance objects and the related application objects from the database.

For more information about database names, see the database_name parameter in CREATE DATABASE (Transact-SQL).

示例

The following example shows how to use the StockInstance database as the instance database. If the StockInstance database exists, Notification Services uses the existing database. If the StockInstance database does not exist, Notification Services creates it.

<DatabaseName>StockInstance</DatabaseName>
