-- 示例

-- 测试表

    ,SendTime datetime ,AcceptUnit varchar ( 10 )

create table accepteTab(ID int identity ( 1 , 1 ),Name varchar ( 10 )
    ,SendUnit varchar ( 10 ),AcceptUnit varchar ( 10 ),Content varchar ( 8000 ))

-- 创建处理的存储过程

-- 创建作业步骤
declare @sql varchar ( 800 )

-- 创建调度

-- 添加目标服务器

-- 创建处理的触发器(新增/修改)

while @@fetch_status = 0
begin
    exec p_JobSet @id
    fetch next from tb into @id
end
close tb
deallocate tb

-- 创建处理的触发器(删除)
create trigger tr_delete on sendTab

go

-- 测试

-- 插入数据
insert sendTab
select ' 文书1 ' , ' 2004/5/1 12:00:00 ' , ' UnitA ' , ' UnitB ' , ' txt '
union all select ' 文书2 ' , ' 2004/5/12 12:00:00 ' , ' UnitA ' , ' UnitB ' , ' txt '
union all select ' 文书3 ' , ' 2004/5/21 12:00:00 ' , ' UnitA ' , ' UnitB ' , ' txt '

-- 修改
update sendTab set name = ' 档案1 ' ,SendTime = ' 2004/5/1 15:00:00 '
where id = 1

-- 删除
delete sendtab where id = 3
go
-- 删除测试
drop table sendTab,accepteTab
drop proc p_JobSet
