Hi all,
While creaing a new database, how to assign username and password? Can we create different usernames and passwords for same database ?
Yes. Is the short answer. You can also set different access privileges for each user: eg. user can read all tables but only update some, and cannot change table schemas etc. See the MySQL manual for full details:
