I have a service CFC that calls my dao CFC a lot. Currently, I just pass
in an object of the dao to the service's init() method and save it to the
variables scope to be used throughout the service. But, I'm wondering if I
would be better off having my service CFCs extend their dao's instead.
A service object is a service object and a DAO is a DAO. They are two very
different objects that serve two very different purposes in an application.
Prefer composition over inheritance. In other words, keep doing what
you're doing there (injecting the DAO).

As usual, Matt Quack is spot on.
I just wanted to add that extending is an IS-A relationship. If your
service extended a DAO, you would say your service is a DAO. That's why
Matt said they are very different objects. Is your service an object that
talks directly to a database? No, it probably
I have two separate queries, basically a table of NEW stuff, and then a
table of OLD stuff that's not been converted to new yet. Not all fields
in the two tables match.
So, first query finds all the matching NEW things
Second query finds all the OLD things that aren't present in the NEW
You need to alias the columns in the original queries to they both match,
and you must have same number of colums, so exclude the ones that don't
exist in both tables.

Is there a way around this?
Just create empty columns when they are missing, ie:
*SELECT*
first_name,
last_name,
off1_name,
off2_name,
off3_name,
atty_id,
email
FROM newstuff
UNION
SELECT
first_name,
last_name,

Ahhh - that works! Didn't know you could do that!

Hi all!
At my company we're once again talking about setting up source control for our
CF.
I've been googling and reading for quite a while now and so far I've gathered,
that we first of all need a SVN server of some sort on a central server, so
that the entire team can access it.
I've
I have a few blog posts on setting up a Subversion server with a few web based
tools. And a good post on the Subversive plugin for CFBuilder.

You are correct in that you need a server for the team to access.
P1: You need to use an SVN
you also wont really be able to have them all working on the same codebase,
this is potential for lots of problems and really defeats the point of
using SVN as your devs will be able to overwrite each others changes. Each
dev would have to log into the server to commit to the repository, which is
