[Zope-DB] Database Data

[Lindstrom Greg - glinds]

Greetings-
I am using Zope 2.6, mySQL 3.23 with the eGenix myODBC DB adaptor (which I
love!) on Windows 98 and have the following questions.

1.  How can I retrieve data from a database query when I know there is only
1 row to be returned (for example, I have a "users" table)?  Currently, I am
using a <dtml-in...> loop and I feel a little silly.

2.  Can I use the <dtml-sqlgroup> with joins?  For example

	SELECT n.name, a.city FROM Names n, Addresses a <dtml-sqlgroup
where>
	<dtml-sqltest myKey col=n.myKey op=eq type=string>
	<dtml-and>
	   n.myKey = a.myKey
	</dtml-sqlgroup>

	I can't figure out how to do the n.myKey = a.myKey, and I will be
doing a lot of joins.  In fact, I'm going nuts learning all that SQL will do
for me; I've pulled out over 100 lines of python script from my application,
and am looking forward to yanking out even more this weekend.

Thanks for your help.
