DB column "grouping" is an xmldb reserved word: cannot add questiosn to activequiz

[moodleulpgc]

Hi:
Active Quiz has a DB table named "activequiz", with a column named "grouping".
But in versions of moodle > 3.5 "grouping" is a reserved word, cannot be used for table or columns names in the DB.
The result is that when trying to use the module and adding a question from bank to a quiz instance, a Fatal error is generated due to to failure tor write to DB in thar field 'grouping'

I have renamed the column to "teamsgrouping", and changed the code in the few scripts that actually contains references to ->grouping (writing ->teamsgrouping) and it works fine.

For 4.x, some renaming of calls to qbank classes is needed, but woks.
