this is how my query looks like...
bu t i am nt very clear as to how correlated update would work?Here is a simple example of the workings:
SQL> create table t
  2  as
  3  select rownum id
  4       , rownum + 2 tid
  5    from all_objects
  6   where rownum <= 5
  7  /
Table created.
SQL> create table s
  2  as
  3  select *
  4    from t
  5  /
Table created.
SQL>
SQL> update s
  2     set tid = tid * 2
  3  /
5 rows updated.
SQL>
SQL> select *
  2    from t
  3  /
        ID        TID
         1          3
         2          4
         3          5
         4          6
         5          7
SQL> select *
  2    from s
  3  /
        ID        TID
         1          6
         2          8
         3         10
         4         12
         5         14
SQL>
SQL>
SQL> update t
  2    set (id, tid) = (select s.id, s.tid
  3                   from s
  4                   where s.id = t.id)
  5  ;
5 rows updated.
SQL> select *
  2    from t
  3  /
        ID        TID
         1          6
         2          8
         3         10
         4         12
         5         14As you can see it works as advertised....
