I think what you need is qResults["val" & loopCount][1] to get just the first row's "val1" value (even if the query only returns 1 row). It's just an educated guess, but it's worth a shot.

Dynamic variable names in QuerySetCell
I'm trying to avoid Evaluate and have hit a wall. I am trying to dynamically call column names from qResults and set the values in a QuerySetCell - val1, val2, val3, val4, etc...

RE: Dynamic Variable Names
evaluate is the least of your problems. lets start with the database. it is
not normalized. read : http://www.swynk.com/friends/putnam/normarticle.asp
for a better explanation. basically, whenever you find yourself making
column names that end with a number, you have a non-normalized table
structure.
regardless... if you were to do say :
the submit would look like this:
value1,value2,value3,value4
you could then treat form.myselect as a list and loop over it to do the
inserts.

Re: Dynamic Variable Names
The problem you are having is because of the database structure. Those
materials fields need to be in a different table with another field that
relates to the project. Any time you have a 1 to Many relationship like
these 20 materials to 1 project, it cries out for two tables.
Here is some example sql, on how you would get the records, if the table was
split into the two parts.
SELECT Projects.ProjectID, Projects.Description, Materials.Material
FROM Projects, Materials
WHERE Projects.ProjectID = #projectID#
AND Projects.ProjectID = Materials.ProjectID
This way all you have to do is insert into the Materials table a new entry
with the projectid and the material, that's it.
I hope that makes sense...
If it's too late to redesign the database, why not just cfparam all of the
form variables on the action page?

Re: Dynamic Variable Names
I know you said you tried evaluate but in this case it would seem to be the way to go.
What was the output? Did you get the syntax wrong? Why is it that evaluate didn't
work for you?
Assuming there will always be at least one material
[psuedocode - you fill in the cf tags]
sql = "insert into mytable (material1"
if number_of_materials > 1
for counter=2 to number of materials
sql += " ,material" & counter
sql += ") values ('" & mat_value1 & "'"
if number_of_materials > 1
for counter=2 to number of materials
temp = "mat_value" & counter
sql += " ,'" & evaluate(temp) & "'"
sql += ")"
cfquery sql
[beware the double and single quotes above. They're hard to see but crucial. You
might also want to parse the values to remove single quotes and escape backslash
before entering them into the database]

Re: Dynamic Variable Names
I havent tried this but according to Michael Dinowitz it should be like
this:
Dynamic Variables
The Variable portion of a CFSET can be set dynamically by placing the text
portion within double quotes (") and surrounding the dynamic portion with
pound signs (#).
The Variable part of a CFSET does not need pound signs unless you're setting
a dynamic variable name, in which case it should be inside double quotes (")
as well.
Wrong:
Right:
When setting a dynamic Variable in a CFSET, remember to place the entire
Variable within double quotes (").

First I set up a couple of strings: Where q is a number from 1-37 passed via url variable. Let's say that url.q is 7. Then qn is 'q7'. So I query the database like this: SELECT #qn# FROM database And it correctly pulls all the results from the 'q7' column. So far so good. But now I want to be able to manipulate the query results and refer to the q7's from the database query. If I refer to #qn# I only get q7 as the result. So how do I have it refer to the variable q7 and not the string q7? Thanks! Jenny ~~ Structure your ColdFusion code with Fusebox.

RE: Dynamic Variable Names
You're trouble is you're not using the evaluate() function (and you're
using # gratuitously :).
This will now be the value of from.id1 instead of the string "form.id1"
(through whatever). There are other ways to handle this as well.
One thing of note is instead of using the for style cfloop, use a while
(conditional) loop and you won't have to pass the number along, just add a
counter.
This will now run from x to the first break in the ints up from it; so 1
until whatever you decide w/o you having to pass a number.
Alternately, if it's all logic you might want to use cfscript.
x = 1;
while (isDefined("form.id" & x)) {
field = evaluate("form.id" & x) ;
if (field eq "Custom") {
// do this is custom
} else {
// do this if not
}
x = x + 1 ;
}

Subject: Dynamic Variable Names
Hi,
In this example I have two pages...with a form post inbetween.
The first page has a lot of text boxes called ID1 to ID16 (so, 16 in total
;) ).these boxes are in a database loop (thus the number to
differentiate them). Also over time the number may change from 16 to 18
etc..so there may be more text boxes.
I also pass this total number (16) to the second page in a hidden field.
On the second page I want to evaluate the value for each one..but as the
total number is not a constant I need to do a loop.
The following code is what I have come up with :
#I#
#varname# = Custom
..end code.
What this is SUPPOSED to be doing is checking if the passed VALUE for
Form.ID1 (through 16) equals "Custom", and if so it does something, else
something else...
.but what it is doing is a literal comparison, so there are NEVER any
true
results to the if statement, when infact with my current code 11 out of 12
should return true.
Can someone help me with this...it may be trivial to some of you..but I need
to get around this ASAP.
Thanks heaps!!!

Re: Dynamic Variable Names in a CFSET
Dave, you're real close. Just do There's also the SetVariable() function that can be used to do the same thing (check the docs). I'm not sure there's much of an advantage to either way of doing it. I believe the above example only works with CF4 and up, while the SetVariable function has been around longer.
