Here’s a command line switch for MySQL that’s both funny and pretty handy:
--i-am-a-dummy Synonym for option --safe-updates, -U.
Yes, there is a MySQL switch called “i-am-a-dummy”. It’s an alias of another switch, which provides more information:
--safe-updates Only allow UPDATE and DELETE that uses keys.
Now, that’s handy. This means you couldn’t accidentally wipe out your table because the system won’t process DELETEs or UPDATEs that don’t specify primary key values. Smart. It strikes me that the alias should be “i-am-not-a-dummy.”
