In this answer, we have shared how to retrieving the last record in each group using MySQL. MySQL 8.0 now supports windowing functions, like almost all popular SQL implementations. With this standard syntax, we can write greatest-n-per-group queries:

FROM messages AS m
SELECT * FROM ranked_messages WHERE rn = 1;
