This is a collection of the most common commands I run while administering Mysql databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Mysql has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.
