Question

我有下表和

tempaddresstable
帐户
前提
地址

以下是详细信息的链接（帐户ID =前提的account_fk）（前提的address_fk =地址的id）

所以唯一的目标是将所有记录信息从tempaddresstable更新到地址表

我已尝试过以下查询，但收到错误

UPDATE ADDRESS AD
SET AD.ADDRESS1 =
  (SELECT (B.TEMPADDRESS1)
   FROM tempAddressTable B,
        ADDRESS AD
   WHERE AD.ID =
       (SELECT (P.ADDRESS_FK)
        FROM ACCOUNT A
        LEFT JOIN tempAddressTable B ON A.EXT_REF = B.TEMPEXTREF
        LEFT JOIN PREMISE P ON A.ID = P.ACCOUNT_FK
        LEFT JOIN ADDRESS AD ON AD.ID = P.ADDRESS_FK
        WHERE A.EXT_REF = B.TEMPEXTREF ))
WHERE EXISTS
    (SELECT 1
     FROM tempAddressTable B
     WHERE AD.ID =
         (SELECT DISTINCT max(P.ADDRESS_FK)
          FROM ACCOUNT A
          LEFT JOIN PREMISE P ON A.ID = P.ACCOUNT_FK
          LEFT JOIN tempAddressTable B ON A.EXT_REF = B.TEMPEXTREF
          WHERE A.EXT_REF = B.TEMPEXTREF ));

错误：

它不适合你吗？

drop table tempaddresstable;
create table tempaddresstable (tempextref number, tempaddress1 varchar2(100));
insert into tempaddresstable values (34, '101 DRCSG117432RES RD TEST');
insert into tempaddresstable values (35, '102 DRCSG117');
insert into tempaddresstable values (36, '100 DRCSG117432RES RD');
commit;

drop table accounts;
create table accounts (id number, ext_ref number);
insert into accounts values (1041261 , 34);
insert into accounts values (1041262 , 35);
insert into accounts values (1041263 , 36);
commit;

drop table premise;
create table premise (id number, account_fk number, address_fk number);
insert into premise values (1044610 ,1041261 ,1041502);
insert into premise values (1044611 ,1041262, 1041503);
insert into premise values (1044612 ,1041263, 1041504);
commit;

drop table address;
create table address (id number, address1 varchar2(100));
insert into address values (1041502, 'test');
insert into address values (1041503, 'test');
insert into address values (1041504, 'test');
commit;


update address a set a.address1 = 
(
with results as 
(select p.address_fk,t.tempaddress1
from accounts aa join tempaddresstable t on aa.ext_ref = t.tempextref join 
premise p on p.account_fk = aa.id  )
select tempaddress1 from results r
where r.address_fk = a.id);

commit;

我承诺犯了更多错误，所以请在生产中实施之前测试我的所有解决方案。最诚挚的问候，阿德南。
