I am inserting records into a table based on a select statement and it is taking way too much time. I have created indexes of the foreign keys and tried to rearrange the where clause to omit records earlier, but to no avail. The statement looks like this:

Insert into table test

      select part_num, 
             nomenclature, 
 
to_char(requisition_date,'yddd')||lpad(preq.document_serial,4,0),
             2,  /*  '53-Purchase'  */
             PSA.TRANS_date,
             requisition_qty, 
             unit_price,
             4  /*  'ALMD Disapproval'  */
        from part_master_catalogs pmc,
             part_requisitions preq,
             part_price_histories pph,
             part_status_assocs psa
       where preq.pmc_id_fk = pmc.pmc_id
         and preq.preq_id = psa.preq_id_fk
         and psa.req_status_cd_fk = 'D'
         AND PSA.TRANS_DATE <= TO_DATE('&&NEWMEDATE','MM-DD-YYYY')
         AND PSA.TRANS_DATE >  TO_DATE('&&LASTMEDATE','MM-DD-YYYY')
         and pmc.pre_approved_purch_flag = 'N'
         and pmc.company_reimburse_flag = 'Y'
         and pph.pph_id = (select max(pph_id) from part_price_histories
                            where preq.pmc_id_fk = pmc_id_fk
                              and requisition_date >= effective_date)

Any ideas?? Any insight would be appreciated.

Thanks,
Laura
