You might have a query tool capable of tasks analagous to simple SQL's, but
there is more to a _relational_ database than just SQL. Or so I think Codd &
Date believed :-)

Sigh...

All this stuff is there, the hardest thing is finding the info about how to do
all the difficult things I wanna do that would be trivial to do if I knew how
to do them properly!

(That's a fun sentence- but don't ask me about the grammar, I don't know the
command for checking that)

Like the ghastly shell script formatting stuff I was trying to do 'til some
helpful sod said use printf. How was I supposed to know there was a shell
version? 

So (hint) if you want to output formatted text strings from a script, try
printf. It's not just a C command. :-)
