Why I'm doing:

The documentation seemed to show that the table name is optional even when the FROM clause was used. I think that's an error. When the FROM clause is used, I think the table name is required. The database name is optional.

What I'm doing:

Changing the line that shows the syntax of the SHOW DATA command.
Its a minor change.
