SQLServer删除数据库

删除时提示：

网上找了一段：

USE MASTER
GO      

DECLARE @dbname SYSNAME
SET @dbname = 'shujk' --这个是要删除的数据库库名      

DECLARE @s NVARCHAR(1000)
DECLARE tb CURSOR LOCAL
FOR
    SELECT s = 'kill   ' + CAST(spid AS VARCHAR)
    FROM   MASTER..sysprocesses
    WHERE  dbid = DB_ID(@dbname)      

OPEN   tb
FETCH   NEXT   FROM   tb   INTO   @s
WHILE @@fetch_status = 0
BEGIN
    EXEC (@s)
    FETCH NEXT FROM tb INTO @s
END
CLOSE   tb
DEALLOCATE   tb      

EXEC ('drop   database   [' + @dbname + ']')
