title: Keep the show_compatibility_56 always ON in MySQL
body: <p>I needed to set up the system variable "show_compatibility_56" to ON in MySQL. So, I run the command <code>set global show_compatibility_56 = on;</code>, and it worked However, I noticed that whenever I stop and then start the MySQL server, this variable goes back to OFF. Any hints on how to keep it <strong>always ON</strong> even if I restart the server?</p>
