下面的两个脚本(用于改变表)是否会产生差异.. ??

脚本1:

alter table ACNT_MGR_HSTRY add DM_BTNUMBER DATA_TYPE ;
alter table ACNT_MGR_HSTRY add DM_BTID DATA_TYPE ;
alter table ACNT_MGR_HSTRY add DM_USERID DATA_TYPE ;
alter table ACNT_MGR_HSTRY add DM_WSID DATA_TYPE ;

脚本2:

alter table  ACNT_MGR_HSTRY
add
(
DM_BTNUMBER DATA_TYPE,  
DM_BTID DATA_TYPE,
DM_USERID DATA_TYPE,
DM_WSID DATA_TYPE
);

将更新使差异.. ???

update OPERATIONAL_UNIT
 set ( BANK_ID=
 ENTY_CODE_ID=
 TIME_ZONE=
 DM_BTNUMBER=
 DM_BTID=
 DM_USERID=
 DM_WSID=
 );

 update OPERATIONAL_UNIT set BANK_ID=;
 update OPERATIONAL_UNIT set ENTY_CODE_ID=;
 update OPERATIONAL_UNIT set TIME_ZONE=;
 update OPERATIONAL_UNIT set DM_BTNUMBER=;
 update OPERATIONAL_UNIT set …
