Hi
I have this query for inserts and it never ends. I need some suggestions , can some one please help ? It will be much appreciated

Hello,
Seem you have partitioned table, try the query without insert statement and then instead of insert use create table as (for test purpose). you should collect stats on all the table involved in this query. How many rows you have in this followign table BENE_SEC_TSKTYPES ? Next time when you post output enclose it in between \ tag to preserve formatting for better readibility.
You can also try using append hint and see if this speeds upINSERT /*+APPEND */  INTO pimitek.bene_sec_pcptnt_final ....
create table mytest_table as
SELECT p.part_id, MAX (th.tskid || tt.tskdesc)
FROM pimitek.bene_sec_pcptnt p
LEFT JOIN
tskident ti
ON SUBSTR (p.part_id, 1, 9) = SUBSTR (ti.fieldvalue, 1, 9)
AND ti.idcode = 18
AND ti.fieldnbr = 1
AND SUBSTR (ti.fieldvalue, 10, 1) = ' '
LEFT JOIN
comptskident ct
ON SUBSTR (p.part_id, 1, 9) = SUBSTR (ct.fieldvalue, 1, 9)
AND ct.idcode = 18
AND ct.fieldnbr = 1
AND SUBSTR (ct.fieldvalue, 10, 1) = ' '
JOIN
tskhist th
ON (ti.tskid = th.tskid OR ct.tskid = th.tskid)
AND th.tskcode IN (SELECT tskcode
FROM tsktype
JOIN
pimitek.bene_sec_tsktypes
ON tskdesc = task_type)
JOIN
tsktype tt
ON th.tskcode = tt.tskcode
WHERE p.part_id NOT IN (SELECT p2.part_id
FROM pimitek.bene_sec_pcptnt_final p2)
GROUP BY p.part_id;
