Pls help me for tuning the querry

Question

Hi Team,
Can any one help me to tune the query below.
The table STG_INT_CASHFLOWS has 20 lahks record with index created for PAYMENTDATE,DEALNUMBER,PAYRECEIVEIND.
Is there any other way like collecting into array and finding the values etc..
SELECT '1'
FROM STG_INT_CASHFLOWS
WHERE PAYMENTDATE < :B4
AND PAYMENTDATE > TO_CHAR (:B3, 'YYYYMMDD')
AND DEALNUMBER = :B2
AND PAYRECEIVEIND = :B1
AND ROWNUM = 1
Thanks.

Answer 1

Logic of my code below.
For test in(
select * from STG_INT_CASHFLOWS ORDER BY dealnumber, payreceiveind, TO_DATE (TRIM (paymentdate), 'yyyymmdd')) Loop
SELECT 0 into Varibale
FROM STG_INT_CASHFLOWS
WHERE PAYMENTDATE < test.PAYMENTDATE
AND PAYMENTDATE > TO_CHAR (sysdate, 'YYYYMMDD')
AND DEALNUMBER = test.dealnumber
AND PAYRECEIVEIND = test.PAYRECEIVEIND
AND ROWNUM = 1
We have some other logice below and select statement used using the cursor values.
End loop;
But we face only performace issue with the main cursor with order by clause. But as per logic order by clause cannot be removed. we will use th select staement mentioned.
