How to optimize a very slow query?
I have this table structure. id is primary key:
id post_id email telegram twitter address refer_link referrer
Table is now relatively big. When I run this query (it has around 9k rows) it takes more than 30 seconds to execute:
select o.email, telegram, twitter, address, IFNULL( (select email from wpkx_airdrop_claim where o.referrer = refer_link ),'') as refer_email, (select count(referrer) from wpkx_airdrop_claim where referrer = o.refer_link ) as refer_count from wpkx_airdrop_claim as o WHERE post_id=8037 order by refer_count DESC
Any idea how to optimize this query to execute it faster?
Thank you.
