Hi, first post :)
I have an interesting project. I have a basic form passing answers
into mysql. I have a db with multiple tables, each table contains
several fields, but I am only concerned with 16 of these fields
which contain the answers "A" "B" "C" "D" etc., not all
fields
contain the same number of answers (ie; some answers have A-G,
some only have A-D to choose from). My problem is extracting the
number of people that chose "A" for answer1, "B" for answer1, etc.
Here is the layout:
acct2301 (table)
answer1-answer16 are my fields
username answer1 answer2 answer3 answer4 answer16
----------------------------------------------------
joeblow A F A E C
someguy A E B B C
joeuser B A E A D
someone D C D A A
I have everything completed as far as getting the answers into the
tables,I just can't figure out the best way to extract the answers
and determine how many chose a given answer for each question.
I have seen some examples using count(*), and (sum) I am thinking
I need to first determine how many A's, B's etc. then perform a
count on the result of that, but that is as far as I have been able
to get.
Ideally a percentage function would be nice (20% chose A for Answer1,
etc.)
Thanks for any help, I sure need it!
