Question

我的SQL Server框上有许多以前缀zzz开头的数据库。

有没有办法执行删除和删除数据文件的DROP DATABASE（或其他方法）？如果打开了连接，我希望它关闭。

基本上我只是希望他们消失。

Answer 1

生成放置脚本，复制/粘贴＆amp;运行：

exec master.sys.sp_msforeachdb 'if ''?'' like ''ZZZ%'' print ''drop database [?]'''

如果勇敢的话，直接删除SQL字符串。

Answer 2

您可以编写动态SQL来执行此操作：

use master
go
declare @dbnames nvarchar(max)
declare @statement nvarchar(max)
declare @closeconnection nvarchar(max)
set @dbnames = ''
set @statement = ''
select @dbnames = @dbnames + ',[' + name + ']' from sys.databases where name like 'zzz%'
if len(@dbnames) = 0
    begin
    print 'no databases to drop'
    end
else
    BEGIN
    SET @closeconnection = 'alter database ' + substring(@dbnames, 2, len(@dbnames))
                            + ' SET SINGLE_USER WITH ROLLBACK IMMEDIATE'
    set @statement = 'drop database ' + substring(@dbnames, 2, len(@dbnames))
    print @statement
    EXEC sp_executesql @closeconnection;
    exec sp_executesql @statement;
    end

通常，关闭与数据库的所有活动连接的语法是：

  --set it to single user to disable any other connections
 ALTER DATABASE YourDatabase SET SINGLE_USER WITH ROLLBACK IMMEDIATE  

 --do your stuff here

 --set it back to multiple users
 ALTER DATABASE YourDatabase SET MULTI_USER

或者，您也可以生成一个动态选择列表，用于填充drop数据库语句以及如下所示的紧密连接语句：

USE master;
Go
SELECT 'DROP DATABASE '+ name, 
       'alter database ' + name + ' SET SINGLE_USER WITH ROLLBACK IMMEDIATE'
FROM sys.databases WHERE name like 'zzz%';
GO

Answer 3

use master;
go

- 这会丢弃所有以t5开头的dbs ....

declare @strsql varchar(500)
declare @curname sysname
select @curname = name from sys.databases
where name like 't5%'

while( @@rowcount> 0)
begin 
set @strsql ='ALTER DATABASE ' +@curname +' SET OFFLINE WITH ROLLBACK IMMEDIATE'
exec (@strsql)
set @strsql ='drop database '+@curname
exec (@strsql)
select @curname = name from sys.databases
where name like 't5%'
end

Answer 4

我修改了benjamin的脚本，所以你只需要声明一次前缀。

use master;
declare @dbPrefix varchar(10)
set @dbPrefix = 'zzz_%';

declare @strsql varchar(500)
declare @curname sysname
select @curname = name from sys.databases
where name like @dbPrefix

while( @@rowcount> 0)
    begin 
        set @strsql ='ALTER DATABASE ' +@curname +' SET SINGLE_USER WITH ROLLBACK IMMEDIATE'
        exec (@strsql)
        set @strsql ='drop database '+@curname
        exec (@strsql)
        select @curname = name from sys.databases
        where name like @dbPrefix
    end
