I have a database where I store all transactions made in a game. (Picture of DB) Now I want to get the value of the last transaction for each player.
I already tried
SELECT MAX(timestamp), value, account_id FROM transactions GROUP BY account_id;
. Here I get the right time and account_id, but not the right value.
Is it possible to solve this problem only with SQL?
CodePudding user response:
In MySQL 8 or later you can use window functions for this:
with cte as (
select *, row_number() over (partition by account_id order by timestamp desc) as rn
from transactions
)
select *
from cte
where rn = 1
CodePudding user response:
select * from table
where id in (select MAX(id) from table group by account_id)
