How to create a derived query?

[Mactacs]

Hi. I'm struggling in creating a query that needs a derivation. Here is my SQLite query :

SELECT * FROM (SELECT * FROM messages AS a ORDER BY a.date_sent DESC,a.time_sent DESC) as c GROUP BY c.client_user_id, c.client_student_id

I converted this query using this dependency and it produces different result compare above query. I don't know what I was lacking. Please help thanks.

Here is my query :

let query1 = (Messages.messagesTable.select(*).order(Messages.messagesTable[Messages.date_sent].desc).order(Messages.messagesTable[Messages.time_sent].desc)).select(*).group(Messages.messagesTable[Messages.client_user_id]).group(Messages.messagesTable[Messages.client_student_id])
