Tunning of below query

Question

Hi,
Please help in tunning of the below.
(SELECT T1.TRANSACTIONID, T1.NARRATION, T1.DEBITCREDITFLAG,
T1.ACCOUNTPRODUCT_ACCPRODID ACCOUNTID, T1.POSTINGDATE, T1.VALUEDATE,T1.AMOUNT from wasadmin.transaction t1 where t1.transactionid in (
select t.transactionid
from wasadmin.transaction t
where T.POSTINGDATE BETWEEN (SELECT BFLASTFREEZETIME FROM bankfusion.BFTB_PERSISTENTTAG)
AND(SELECT BFCURRENTFREEZETIME FROM bankfusion.BFTB_PERSISTENTTAG)
group by t.transactionid
having sum(t.amount) != 0))
Transaction table is huge table with lot of records. it taking 30 min fetch the data.

Answer 1

It looks like the table bankfusion.BFTB_PERSISTENTTAG has only one row. Is this true?
How about this:
SELECT t1.TRANSACTIONID, t1.NARRATION, t1.DEBITCREDITFLAG, t1.ACCOUNTPRODUCT_ACCPRODID ACCOUNTID,
       t1.POSTINGDATE, t1.VALUEDATE, t1.AMOUNT
from wasadmin.transaction t1,     
     (select transactionid, sum(amount) amount
        from wasadmin.transaction
       where POSTINGDATE BETWEEN (SELECT BFLASTFREEZETIME FROM bankfusion.BFTB_PERSISTENTTAG)
                             AND (SELECT BFCURRENTFREEZETIME FROM bankfusion.BFTB_PERSISTENTTAG)
    group by transactionid
      having sum(amount) != 0) t2
where t1.transactionid = t2.transactionid
  and t1.POSTINGDATE BETWEEN (SELECT BFLASTFREEZETIME FROM bankfusion.BFTB_PERSISTENTTAG)
                         AND (SELECT BFCURRENTFREEZETIME FROM bankfusion.BFTB_PERSISTENTTAG)I would actually prefer to see the BFTB_PERSISTENTTAG values obtained beforehand and then plugged into the main query with bind variables:
select BFLASTFREEZETIME, BFCURRENTFREEZETIME
into v_last_freeze_time, v_curr_freeze_time
from  bankfusion.BFTB_PERSISTENTTAG;
SELECT t1.TRANSACTIONID, t1.NARRATION, t1.DEBITCREDITFLAG, t1.ACCOUNTPRODUCT_ACCPRODID ACCOUNTID,
       t1.POSTINGDATE, t1.VALUEDATE, t1.AMOUNT
from wasadmin.transaction t1,     
     (select transactionid, sum(amount) amount
        from wasadmin.transaction
       where POSTINGDATE BETWEEN v_last_freeze_time AND v_curr_freeze_time
    group by transactionid
      having sum(amount) != 0) t2
where t1.transactionid = t2.transactionid
  and t1.POSTINGDATE BETWEEN v_last_freeze_time AND v_curr_freeze_time
