Changing default sorting behavior of mysql

Question

I have a table in my database.

+--------+-------------+------+-----+---------+----------------+
| Field  | Type        | Null | Key | Default | Extra                 


        

Answer 1

select * from students order by rollno asc; will return your results sorted by that column. It should be noted that there is no default sorting behavior as far as data is actually stored in the database (aside from identities and indexes); you should never depend on your results being sorted a certain way unless you explicitly sort them (using order by).
