/**
|
|
* This script fixes use of id instead of iid for the exercises
|
|
* The main issue fixed by this script is that c_quiz.id, c_quiz_question.id
|
|
* and c_quiz_answer.id used to be different from the iid field in those same
|
|
* tables, but has been the same since about 2016.
|
|
* This script goes through the tables that potentially use this old id as
|
|
* a reference rather than the new iid, and replaces those records with the
|
|
* new iid.
