Hi,

I am using MAX function in my query, which takes more cost (around 1,90,0000)
SELECT * FROM (SELECT Balance, product_id,
MAX(Balance) OVER(PARITION BY a.link_id,a.exp_value, a.party_id) as Max_balance
key,
range
from table_a a , table_b b
where a.id = b.id )X
where Balance = Max_balance

Is there any way to reduce execution time of this query?

How could someone tune a query just by looking at it? No test case, no information. You did not follow even the minimal forum rules in order to help you.
