Arrays or Variable

Question

Hi,
I’m trying to get a pass rating from my database, this
information is not in the database but it’s calculated from
information in the database.
I have 1500 user enrolled in my training and each individual
is in pps_principals.name
What I want is the top 10 pass rating. My thoughts on with
would be-
1. Query pulling all the names from the database and saving
them as a variable/array?
2. Query using the variable/array to count each persons
passes and saving them as variables/arrays?
3. Query using the variable/array to count each persons fails
and saving them as variables/arrays?
4. Do the calculations for the pass rate then display the top
10
Will this work and how?
Here’s what I have for 1 user, which gives me a pass
rating.

You are going to want to get all of that logic into a single
query if you want to pull the top 10 from 1500. Otherwise you are
going have to pull all of the records, make all of the
calculations, sort them, then display. Doing this in real-time on a
page loaded by an end user would be punishment, both for them and
for anyone else who may share your installation of CF.
Unfortunately trying to reverse engineer your database based
on these queries would take a little to much time and would likely
be prone to error. If you would like a solid response, I would
recommend creating a database diagram if you haven't already, take
a screen capture, then send us a link to the image.
