I have a 117 different pages. What I'm trying to do is call icons from a separate table which will be the same for all 117 pages, that's why I've stored them in a different table. But I need to call the icons among the data from the other table.

Answer 1

even if you get this working this many hits on your database is a bad idea and will be very slow I would re engineer this to only hit the database once or at most twice to get all the values you need

Possible ideas

OPT A write view that contains everything you need joint originally from the icons table then to the champions table either duplicating the champions for each icon then just create a couple of loops

OPT B get all the icons then and pop them in a class structure to then retrieve as you need them from memory rather than per record.
