How can I clear the screen in the MySQL console? [duplicate]
Another possibility is to issue a system command.
For Linux:
mysql> system clear;
For Windows (I'd guess. For Linux I'm sure though):
mysql> system cls;
Try your terminal application's screen clear. There is no such thing as a command to clean the MySQL shell.
On a Mac, you can go to menu Edit → Clear Screen or use the keyboard shortcut ⌥ + Cmd + L.
