Rehash command in MySQL

Question

What is the command in MySQL to auto-complete the keywords (like the working of tab in Ubuntu Terminal). I use the rehash command, sometimes it works, but sometimes it does not.

Is there any possible alternative for it?

Answer 1

The shortcut for REHASH; is \#. Interestingly, I have also discovered on one server (CentOS 6.x, MySQL 5.1) that REHASH does not work yet \# does.
