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 p_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='是'
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='是'
end
备注说明：
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：update、insert、delete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。
