在SQL Server中更新现有值时，将现有列值插入到新表中

Question

我是SQL Server的新手。

我需要一个答案，我有一个表tblemployee ，列是

empid,
name,
paddr1,
paddr2,
pcity,
pstate,
pzip,
caddr1,
caddr2,
ccity,
cstate,
czip

我有另一个表tblpaddresshistory并且列是

paddrlistid,
paddr1,
paddr2,
pcity,
pstate,
pzip

我还有另一个表tblcaddresshistory与这些列

caddrlistid,
caddr1,
caddr2,
ccity,
cstate,
czip

这里是我的问题：当我更新tblemployee列值的paddr1, paddr2, pcity, pstate, pzip, caddr1, caddr2, ccity, cstate, czip ，旧的值应该插入tblpaddresshistory和tblcaddresshistory和新的价值观应该是在tblemployee更新。

Try with this trigger

CREATE TRIGGER dbo.tr_tblemployee
ON dbo.tblemployee
AFTER UPDATE
AS
  BEGIN
      IF ( UPDATE(paddr1)
            OR UPDATE(paddr2)
            OR UPDATE (pcity)
            OR UPDATE(pstate)
            OR UPDATE(pzip) )
        BEGIN
            INSERT INTO dbo.tblpaddresshistory
                        (paddr1,
                         paddr2,
                         pcity,
                         pstate,
                         pzip)
            SELECT paddr1,
                   paddr2,
                   pcity,
                   pstate,
                   pzip
            FROM   deleted;
        END

      IF ( UPDATE(caddr1)
            OR UPDATE(caddr2)
            OR UPDATE (ccity)
            OR UPDATE(cstate)
            OR UPDATE(czip) )
        BEGIN
            INSERT INTO dbo.tblcaddresshistory
                        (caddr1,
                         caddr2,
                         ccity,
                         cstate,
                         czip)
            SELECT caddr1,
                   caddr2,
                   ccity,
                   cstate,
                   czip
            FROM   deleted;
        END
  END;
