Question

I have a table with the following fields

ID, date, user

now I want to return the ID of the entry with the latest date per user.

I have a solution where I query for the latest date per user and then get the id based on the date and user.

But I want to get the ID directly in one query because I think its wrong to have a JOIN query identify the ID based on date and user.
Doesn’t it defeat the whole concept of the ID? What if I have 2 people editing the same user in the same second?

Anyone knows how to do that?

Answer 1

Are your IDs sequential and increasing?

If so

SELECT User, Max(ID), Max(date)
FROM table
GROUP BY user

Otherwise, nothing wrong with the join.
