需求说明:培训记录处录入“外出培训”记录,保存后同步外出培训合同至“合同模块”


培训记录表PX_Record创建触发器

步骤一、新建触发器:[insert_htandAL]

步骤二、当PeiXun_Record表有INSERT,DELETE,UPDATE操作,则在触发器中执行INSERT,DELETE,UPDATE 操作将相关改变同步至合同表Emp_HT,必须用PX_Record表中Pxr_ID字段做唯一标识过滤

执行代码如下:

 

USE [XXXXX]

GO

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

ALTER TRIGGER [dbo].[insert_htandAL]

   ON  [dbo].[PX_Record]

   for INSERT,DELETE,UPDATE

AS

BEGIN

--01新增操作

if(exists(select 1 from inserted) and not exists(select 1 from deleted))

insert into Emp_HT (Comp_Code,Ht_code,Ht_empid,Ht_class,Ht_StartDate,Ht_EndDate,Ht_OldID,Ht_Num,Ht_Status,Ht_IsZhiXing,Ht_ContinueDesc,Ht_StopDesc

,Ht_EndDesc,Ht_desc,Ht_memo,createby,createtime,updateby,updatetime,Ht_Company,Ht_Year,G_htzdr,Ht_DocPath,Ht_Template,Ht_TemplatePath,G_pxid)

select a.Comp_Code,Emp_code,Pxr_empid,'02',G_sxDate,G_shxDate,null,1,0,1,null,null

,null,null,Pxr_memo,a.createby,a.createtime,a.updateby,a.updatetime,null,G_qdnx,null,null,null,null,Pxr_ID

from inserted a

inner join Emp_Base b on a.Pxr_empid=b.Emp_id

where isnull(pxr_class,0)=1 and G_ifpxxy=''

END

 

--02删除操作

if(not exists(select 1 from inserted) and exists(select 1 from deleted))

 begin

delete from Emp_HT

 where G_pxid in(select Pxr_ID from deleted)

end

 

 --03更新操作

 if(exists(select 1 from inserted) and exists(select 1 from deleted))

 begin

update Emp_HT set

 Ht_StartDate=a.G_sxDate ,

 Ht_EndDate=a.G_shxDate,

 Ht_Year=a.G_qdnx,

 updateby=a.updateby,

 updatetime=a.updatetime

 from inserted a

 where G_pxid=a.Pxr_ID and isnull(a.pxr_class,0)=1 and a.G_ifpxxy=''

end

触发器简介:

触发器是一种特殊的存储过程,它的执行不是由程序调用,也不是手动执行,而是由事件来触发。触发器是当对某一个表进行操作。例如:updateinsertdelete这些操作的时候,系统会自动调用执行该表上对应的触发器。



-- 查询已存在的触发器
select * from sys.triggers;
select * from sys.objects where type = 'TR';
select * from sysobjects where xtype='TR'


 -- 查看触发器触发事件对象
 select a.type_desc,b.* from sys.trigger_events a
 inner join sys.triggers b on a.object_id = b.object_id
 where b.name = 'insert_hetongandAskLeave';
 
 -- 查询触发器的 T-SQL 文本
  exec sp_helptext 'insert_hetongandAskLeave';
 
 
--禁用触发器
disable trigger trigger_Stu_InsteadOf on Student;    -- trigger_Stu_InsteadOf 触发器名称
--启用触发器
enable trigger trigger_Stu_InsteadOf on Student;    -- trigger_Stu_InsteadOf 触发器名称
