Hi,
I am facing problems with the GROUP BY clause. It takes a lot of time to
return with the values.
I am trying the following:
SELECT COUNT(1) FROM VW_INSERT_RIP WHERE USER_KEY = '8888'
This query takes 214 seconds to return the value - 785,000 records from
60,000,000 records.
The view internally joins 3 tables. It has index on the FUND_PRICE table
(with 60,000,000 odd records) but not on the other lighter tables.
Please help.
Regards,
Hemant.
