复制代码 代码如下:

use master

declare @dbname varchar(60)

declare @backsql varchar(1000)

declare mycursor cursor for

select [name] from sysdatabases

where [name] not in (‘master’,’model’,’msdb’,’tempdb’)

order by [name]

open mycursor

fetch next from mycursor into @dbname

while(@@fetch_status = 0)

begin

if datename(weekday, getdate())=’星期三’ –每周三覆盖上周三的

begin

select @backsql=’backup database [‘+@dbname+’] to disk=”e:\dbbackup\’+@dbname+’星期三.bak” with format’

end

else–每天覆盖上一天的

begin

select @backsql=’backup database [‘+@dbname+’] to disk=”e:\dbbackup\’+@dbname+’autoback.bak” with format’

end

exec(@backsql)

fetch next from mycursor into @dbname

end

close mycursor

deallocate mycursor
