Hi,
I have a base table with 10,000 rows.The base table columns will store 8 diff IDs.To display with the description i'm doing outer joining with 8 tables.
In that 8 one table contains nearly 4 lakhs rows & rest of the tables contains some 100 rows.
My query takes nearly 20 min. to execute. HOw to tune that.
As want tune this with in half-day,pls try send some tips & suggestions imm.
Thanks in advance

Please suggest me
please post the explain plan
Is the delay is 'coz of the decodes in select st ?
Is there any other alternatives for that ?
Does this run? Perhaps there's some cut & paste errors:Does it give the right result? The following will NOT give an outer join since deficient rows in fis will have NULL columns:Quote:
--feed_instrm_measr fim, - fin_instrm_measr fim, - (
select fia.secnd_fin_instrm_id, fia.prim_fin_instrm_id,
