Join Tables in Connect BY

Question

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
Hi, I have the following Example. i am getting the require output if i hardcode the values in START WITH CLAUSE
but instead of hard coading the values how can i join the table .
WITH Current_ids AS (SELECT   100 ID FROM DUAL
                     UNION
                     SELECT   105 ID FROM DUAL),
    Hirerchy AS (SELECT   100 ID, 101 parent_id FROM DUAL
                 UNION ALL
                 SELECT   101 ID, 102 parent_id FROM DUAL
                 UNION ALL
                 SELECT   102 ID, 103 parent_id FROM DUAL
                 UNION ALL
                 SELECT   103 ID, 104 parent_id FROM DUAL
                 UNION ALL
                 SELECT   105 ID, 106 parent_id FROM DUAL
                 UNION ALL
                 SELECT   106 ID, 107 parent_id FROM DUAL
                 UNION ALL
                 SELECT   107 ID, 108 parent_id FROM DUAL)
    SELECT   CONNECT_BY_ROOT (ID) ID,
             TRIM (SYS_CONNECT_BY_PATH (B.id, ' ') || ' ' || B.parent_id) PATH
      FROM   Hirerchy b
     WHERE   CONNECT_BY_ISLEAF = 1
START WITH   b.id IN (101, 105) /******** Change this to get the values from Current_ids ********/
CONNECT BY   PRIOR b.parent_id = b.id
output
ID     PATH
101     101 102 103 104
105     105 106 107 108Thanks Every one for the Support and Help

I'm sorry . is this a trick? :)
WITH Current_ids AS (SELECT   101 ID FROM DUAL
                     UNION
                     SELECT   105 ID FROM DUAL),
    Hirerchy AS (SELECT   100 ID, 101 parent_id FROM DUAL
                 UNION ALL
                 SELECT   101 ID, 102 parent_id FROM DUAL
                 UNION ALL
                 SELECT   102 ID, 103 parent_id FROM DUAL
                 UNION ALL
                 SELECT   103 ID, 104 parent_id FROM DUAL
                 UNION ALL
                 SELECT   105 ID, 106 parent_id FROM DUAL
                 UNION ALL
                 SELECT   106 ID, 107 parent_id FROM DUAL
                 UNION ALL
                 SELECT   107 ID, 108 parent_id FROM DUAL)
    SELECT   CONNECT_BY_ROOT (ID) ID,
             TRIM (SYS_CONNECT_BY_PATH (B.id, ' ') || ' ' || B.parent_id) PATH
      FROM   Hirerchy b
     WHERE   CONNECT_BY_ISLEAF = 1
--START WITH   b.id IN (101, 105) /******** Change this to get the values from Current_ids ********/
START WITH   b.id IN (select id from current_ids)
CONNECT BY   PRIOR b.parent_id = b.idSeems to work for me.
Of course, you had 100 in the Current_ids .. and 101 in your hardcoding .. once I changed that, they matched. shrug
