经常需要查一些信息， 想写视图来返回数据以提高效率，但是用试视图不能传参，只好想到改存储过程。记录一下语法，方便以后做项目时候想不起来了用。
1：传字段返回datatable
2： 传字段回一串字符
3: 传字符串返回datable
4：存储过程调用存储过程
--加半个小时
(select dateadd(MINUTE,30,GETDATE() ))--UnLockTime 往后加半个小时 CONVERT(varchar(100), @UnLockTime, 20)
--转成可以拼接字符串的格式
set @strOutput='0~由于您最近输错5次密码已被锁定，请在'+CONVERT(varchar(100), @UnLockTime, 20) +'之后再尝试登录~'+CAST(@Id AS NVARCHAR(10))
1：传字段返回datatable
