I can do it in PHP but how with CF?

Question

I have a sizable database that keeps track of profit per job
that goes back several years. What I need to do is create a table
layout of:
1) Customer's ID
2) Total $ from 2004
3) Total $ from 2005
3) Total $ from 2006
In PHP I do a fair amount of query sorting with arrays, but
since CF doesn't support testing an empty array element that seems
to be out.
The process I'm using is basically this: (in PHP)
SELECT SysID, ProfitAmount, Year
FROM Table
WHERE year = '2004' or year = '2005' or year = '2006'
while($row = mysql_fetch_assoc($query){
$job[$row[SysID]][$row['Year']] += $row['ProfitAmount'];
It's possibIe that a client didn't do business one year, so
potentially this can cause empty elements:
$job[1234][2004] = 100.00
$job[1234][2005] = NULL
$job[1234][2006] = 300.00
I've tried using GROUP BY in SQL as well as QofQ but I'm not
having much luck. I really want to give CF a fair shot, it seems
like it can do some impressive things, but something so simple to
do in PHP seems almost impossible to do here outside of running 4
queries, 4 QofQ (to join results) and a bunch of cfcatches so an
empty array elements won't crash the whole thing. What am I missing
here?

Quotes around the year? That's scary. In any event, if this
query:
SELECT SysID, ProfitAmount, Year as TheYear
FROM Table
WHERE year = '2004' or year = '2005' or year = '2006'
returned rows for 2004 and 2006 but not 2005, but you want to
display all 3 years, here is one way to do it. Let's call that
query q1.
<cfscript>
YearsIWant = "2004,2005,2006";
for (i = 1; i lte ListLen(YearsIWant); i = 1 + 1) {
ThisYear = ListGetAt(YearsIWant, i);
// if ThisYear is not in the query, add it.
if (ListFind(ValueList, q1.TheYear) is 0) {
x = QueryAddRow(q1, 1);
x = QuerySetCell(q1, "TheYear", ThisYear);
x= QuerySetCell(q1, "ProfitAmount", 0);
x = QuerySetCell(q1, "SysId", "something");
} // end if
} // end loop
</cfscript>
<cfquery name ="q2" dbtype = "Query">
select SysId, ProfitAmount, TheYear
from q1
order by TheYear
</cfqyuery>
Then output q2 as you see fit.
