I turned on slow query monitor in MySQL
config.
Below is the query and time:
Time: 160330 20:54:11 User@Host: user[user] @ [xx.xx.xxx.xxx] Query_time: 8.794170 Lock_time: 0.000141 Rows_sent: 3942 Rows_examined: 4742825 SET timestamp=1459371251;
SELECT (SELECT (CASE WHEN ce_type = 'IN' then SUM(payment_amount)
END) as debit
FROM customer_payment_options cpo
WHERE wallet_id=cw.id
AND (cpo.real_account_type='HQ')
AND cpo.source_country_id='40'
GROUP BY cpo.wallet_id)
as debit,
(SELECT SUM(payment_amount)
as credit
FROM customer_payment_options cpo
WHERE wallet_id=cw.id
AND (cpo.real_account_type='HQ')
AND cpo.tran_id IS NOT NULL
AND cpo.source_country_id='40'
GROUP BY cpo.wallet_id)
as credit
FROM customer_wallet cw
WHERE cw.company_id='1'
AND cw.currency='40'
AND cw.is_approved = '1'
AND DATE(cw.date_added) < '2016-03-30';
Indexes on customer_payment_options
:
company_id
tran_id
ce_id
wallet_id
What should I do to improve it's performance?
