I'm with Mike on this one. The query is fine, as you know from running it on

Sticky, meaning that a variable holds the same value across multiple

all users of that application.

Completely agree with Brad. Also wouldn't hurt to ensure that the

and 'placeholder' as appropriate.

Okay, that makes sense, but I'm thinking that you won't be able to do the

Eventually integers do get too large for the database field. If you're
truly adding a million new IDs / day, that could happen. There's a fairly
modest upper limit to 'int', so definitely look at 'bigint' (SQL Server) to
handle integer IDs if you take that route.
Collation's not the problem, but the Data Type of your columns might be.
Make sure you're using nvarchar ntext (not varchar and text) [SQL Server]
and ensure that both page and form encoding allow Unicode, like using
charset UTF-8.
Better yet, just define the function outside the loop (top of the
template?) and then just call it from inside your loop.

Just looking at the link you sent in a browser, the image is nearly all
black, which makes me think it's a CMYK jpeg, instead of an RGB jpeg.
Browsers and the Adobe image engine can't handle the CMYK ... that's my
guess.
The other benefit of createUUID() is that you can later split / combine
records from different tables if you ever need to, such as pulling
production records down to review in development ... no integer clashes
when you've got fully unique values across the tables and datasources.
Looks like that was fixed in JVM 1.3.1_04 ... and CF 8 is shipped with 1.6.0_4,

I have also had decent luck with the hidden form field. In your form, put
an input type=text in a div that is display: none, so the field isn't
technically hidden, but a human won't see it, and then call the field
something like name=lastName, something that a bot will always fill out.
Assuming you're on CFMX 7 or 8, you no longer need to LOCK on READ, so if
you're concerned about race conditions on the WRITE, just do:
cflock scope=session type=EXCLUSIVE timeout=10
cfset session.foo = application.bar
/cflock
(timeout can be whatever is appropriate)
You could do it better with aggregate functions, but this will work, too.
Just make the completionDate lookup part of your base query (note the LEFT
OUTER JOIN), and then use the GROUP attribute of the CFOUTPUT tag to do the
looping for you in one go:
cfquery name=getCareManagers
That would work, but it's unnecessary overhead unless you're still on CF 5.

Dunno about the raw Java handler, but it appears that a custom CF 404

splendidly *except* that it doesn't pick up the FORM scope at all. Now,
