删除根据变量确定表的存储过程
我要实现的功能是删除某个用户的某个表.
用户名和表名都是变量
create   procedure   delete_all
@username   varchar(50),
@delete_table   varchar(50)
as
execute( '
delete   *
from   '   +@delete_table+ '
where   userID=(selecte   userID   from   blog_users   where   username= '+@username)

我写的这个好像是错误的?

应该怎么写呢?谢了!

------解决方案--------------------
try


create procedure delete_all
@username varchar(50),
@delete_table varchar(50)
as
execute( '
delete *
from ' +@delete_table+ '
where userID=(selecte userID from blog_users where username= ' ' '+@username + ' ' ') ')
GO
------解决方案--------------------
1 delete from而不是delete * from
2 单引号之中引用单引号,需要把 '变成 ' '

create procedure delete_all
@username varchar(50),
@delete_table varchar(50)
as
execute( '
delete
from '+@delete_table+ '
where userID=(selecte userID from blog_users where username= ' ' '+@username + ' ' ')
')
GO
