Would we have to do a DBMS query on this, or can it be done in the
Search action?

I would do it in the query
SELECT question_text, RAND() as random FROM questions ORDER BY
random LIMIT 7

Hi fellow members of the Tango programming community!
I am actually kind of stuck on this and am wondering if you guys
could get me some insight. I'm attempting to get x number of
random questions from y which happens to the be total number of
records.
This is for a online testing engine.
The steps below explain the logic.
1) Find total number questions needing to be randomized (assigned
in an <@ARG>) - let's say in this case we're looking at a total
number of 7
2) Search database with all questions and store in all_questions
array.
3) Create a blank array called create_test_questions with initial
value to be "0"
4) Create a blank array called empty array called random_question
with initial value to be "0"
5) Create a loop while the <@NUMROWS of create_test_questions> is
less than the total questions needing to be randomized (7)
5a. While in this loop, do the following:
<@ASSIGN name="random_question" value="<@RANDOM low='1'
high='7'> The high is being passed in argument form...I'm
hardcoding here for savings
<@ROWS array="create_test_questions" step="1">
<@IFEQUAL value1="@@request$create_test_questions[1,1]"
value2="@@request$random_question[1,1]>
<@ASSIGN name="already_there" scope="request"
value="Y">
</@IF>
<@IFEMPTY @@request$already_there>
<@ADDROWS array="create_test_questions" value="@@request
$random_question">
</@IF>
</@ROWS>
This created an infinite loop. I changed the loop to be a for loop
where the counter var is less than 7 and it's executing correctly,
but it's not adding to the create_test_questions array...
I might be kind of retarded here...but I don't really see what I'm
doing wrong...
any guidance would be much appreciated :)
