MySQL in a Nutshell, 2nd Edition

Name

HELP

Synopsis

HELP [{'command | reserve_word'}]

You can use this statement to access built-in documentation. Enter HELP alone to display a list of MySQL commands for which you may display documentation. Typing HELP contents displays a table of contents for this internal documentation. For quick reference, you can also give an SQL statement or clause:

HELP SELECT;

This displays the syntax for the SELECT statement along with a brief description of some of the clauses. Similarly, entering HELP SHOW gives you a list of SQL statements beginning with SHOW.
