select * from tb_cmd   order by OrderNumber asc 

--IsRun ：是否执行语句 0 表示 未执行,1表示已执行
----------------------------------

---解释一下本人的需求 

----通过执行一个 带参数的存储过程  exec  OpreateTB('OpreateUser','IsRun')   -- 更新这张表的数据  （RunTime，RunStatus,BetweenTime,RunLog,IsRun）

--- RunTime 这条语句的执行时间  

-- RunStatus 为执行语句是否成功  1表示执行成功   0 表示异常  NULL 就是还未执行 -1表示回滚

---BetweenTime ：执行这条语句所用时间

--RunLog 执行 返回的消息结果  如（1行影响）

--执行过程如果有错误语句直接回滚 并且 Runlog 都更新为'回滚'

--执行 按照 OrderNumber 升序执行语句

建表语句：

if object_id('tb') is not null 
    drop table tb
go

insert into   tb_CMd (sqlevent,OrderNumber,IsRun,OpreateUser )values('create table tb (id int ,name varchar(10))',1,0,'Tom')
insert into   tb_CMd (sqlevent,OrderNumber,IsRun,OpreateUser  )values('insert into tb select 1,''test1''',2,0,'Tom')
insert into   tb_CMd (sqlevent,OrderNumber,IsRun,OpreateUser  )values('insert into tb select.  2,''test2''',3,0,'Tom')

 

存储过程：

create proc dbo.OpreateTB
--@OpreateUser nvarchar(100),
--@IsRun nvarchar(10)
as

declare @i int
declare @start datetime
declare @sql nvarchar(max)
declare @OrderNumber int
declare @error int
declare @ROWCOUNT int

set @i = 1;

while @i <= (select COUNT(*) from [TB_CMD])
begin

   --按照[OrderNumber]进行了排序，每次取出1条
   ;with t
   as
   (
     select *,
            ROW_NUMBER() over(order by [OrderNumber]) rownum

   select  @sql = [SqlEvent],
           @OrderNumber = [OrderNumber]

   set @start = GETDATE()
   
   exec(@sql);
