Join to an oracle table valued function

Is is possible to join to an Oracle table valued function?

SELECT 
   *
FROM 
  SOME_TABLE a
INNER JOIN 
  TABLE(GET_TABLE_L开发者_StackOverflowIST()) b ON = a.COL_A = b.COL_A

You can, yes. Since I don't have your get_TrfrmEngMachineInfoT function, I'll create my own collection and join it to the EMP table in the SCOTT schema

SQL> create or replace type typ_person
  2      as object (
  3        person_id number,
  4        person_name varchar2(30)
  5      );
  6  /

Type created.

SQL> create or replace type tbl_person
  2    as table of typ_person;
  3  /

Type created.

  1  create or replace function get_person_list
  2    return tbl_person
  3  is
  4    l_people tbl_person;
  5  begin
  6    select typ_person( empno, ename )
  7      bulk collect into l_people
  8      from emp;
  9    return l_people;
 10* end;
SQL> /

Function created.

SQL> select p.*
  2    from emp e
  3         join table( get_person_list() ) p on (p.person_id = e.empno);

SELECT a.*, b.*
from table_name a cross join table ( myFunc(a.id) ) b

Maybe this can work for you...

SELECT table_name.*, myFunc(table_name.OBJID) as new_field_name from table_name

That will select everything from the table_name table and add the result of the function in to the new set.

myFunc uses table_name.OBJID field to match some records and do whatever...
