As David said, don't let the input format dictate your data model. That
format will give you a headache somewhere on the line, and I'm telling
you the earlier you handle it in the process, the less headache you will
get.
For this case, I would unpack the string with a list-to-table function,
see http://www.sommarskog.se/arrays-in-sql.html#iter-list-of-integers
for such a function. For your case you would have handle listpos 1, 2
and 3 individually, and then the answers would be everything above 4.
You could use the function as is, but you could also adapt it so it
directly unpacks into the format you need.
