Please Help, I'm a rookie...
I'm developing a chart to track cycle time for each month. If the closed date is 05/10/07, at the end of May we will subtract 05/01/07 from 05/10/07 and cycle time will be 9 days. I have this part working. How do I sum the cycle time for each month and get an average?

This
WHERE '#May07#' LIKE '#ChartQuery.mmyycldte#'
is backwards plus you need wildcards.

I've used the DateDiff function but it doesn't work with SELECT. I started working with a Q of Q and it selects the correct criteria; however, it's giving me a sum of all the entries and I can't figure out how to get it to sum for just the entries that meet the correct criteria. Here's my current code: Thanks!
<cfquery name="ChartQuery" datasource="#Datasource#">
SELECT rcscid, to_char(rcsccontactdte, 'mm/yyyy')"mmyycdte", rcscname, rcscorg, rcscclosedte, to_char(rcscclosedte, 'mm/yyyy')"mmyycldte", to_char(rcscclosedte, 'mm/dd/yyyy')"cldte", rcscaction, rcscsolution, to_char(rcscmgmtdte, 'mm/dd/yyyy')"mdte", rcscbuy, rcscship, rcscfail, rcscycletime
FROM reccusser
ORDER BY rcscid
</cfquery>

Pretty well all dbs allow you to select sums and averages. Even query of queries supports it. Looping is probably unnecessary.

Most databases have a DateDiff() function you can use. In MS SQL, the syntax would be:

SELECT DateDiff(d, startDate, endDate) as 'cycleTime'
FROM myTable

the above example builds it into your Query results, then its just a matter of performing a little math while you loop.

If you need to dynamically the start date (1st of the month) for a given closed date, you can extract the month and year from the closed date using you database's DatePart() function.
