I have the tables below and

1. tempaddresstable
2. account
3. premise
4. address

Here is the link of details(id of account = account_fk of premise) (address_fk of premise = id of address)

So only goal is to update all the records info from tempaddresstable to address table

I have tried the below query but I am getting error

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 ));

Error :

**SQL Error: ORA-01427: single-row subquery returns more than one row 01427. 00000 - "single-row subquery returns more than one row" Cause:
