Question

I have a register and login site where people can click save progress on a form and it inserts a new row with their session id in column 2 as (user_id).

I also have an admin login where I can see their entries but it shows a list all their saves.

I wonder if you could help me figure out a query to list all the latest save progresses of each unique person? like (id,user_id,name,score): (3,3,bob, score 5) (6,4,sam, score 30) without showing all saves of a user’s past saves like:
(1,3,bob, score 5) (2,4,sam, score 30) (3,3,bob, score 5) (4,4,sam, score 30)
I need the latest save of each user.

Like the latest id of a distinct list of user_id. Hope this makes sense. Thanks!

Answer 1

select user_id,name,score from your_table where (user_id,id) in (select user_id,max(id) from your_table group by user_id)
