如何在MySQL中按用户选择最后一条记录？

Question

I will like to ask how I could select the last record by user in MySQL?

The following is my query string - which obviously did not work:

SELECT *
FROM (SELECT * FROM team_notes where `username`='$username')
ORDER BY ID DESC LIMIT 1

Answer 1

Not sure why you use sub query for this, if you must use it, try this:

SELECT *
FROM (SELECT * FROM team_notes where `username`='$username') t
ORDER BY ID DESC LIMIT 1

Every sub query must have a table alias.

And I think you also can do it like this:

SELECT * FROM team_notes WHERE `username`='$username' ORDER BY ID DESC LIMIT 1
