You can do it with a sub-query   SELECT   FROM       SELECT   FROM table ORDER BY id DESC LIMIT 50   sub ORDER BY id ASC   This will select the last 50 rows from table  and then order them in ascending order

SELECT   FROM table ORDER BY id DESC datechat desc LIMIT 50   If you have a date field that is storing the date and time  on which the chat was sent or any field that is filled with incrementally order by DESC  or desinscrementally  order by ASC  data per row put it as second column on which the data should be order   That s what worked for me     hope it will help
