MySQL Basics In Pictures
Remove a user
  1. Type:

    DELETE FROM user WHERE (user='marty' OR user='mary');

    then press ENTER.

    The command string DELETE FROM user deletes a record from the table user. Like mysql, user is a table that's included in the MySQL Server database.

    WHERE (user='marty' OR user='mary') means that a record is deleted from the table user WHERE the user is 'marty' or 'mary'.
