Ok, I need some sleep, now I see what it does, which is probably not
what the user wanted, but I have fixed the driver to it doesn't throw an
exception.

As I said, I have no idea how the backend handles it when it is quoted.
You mention that it's not a column reference, but it does get data from
the id column?

Uh ... when you put single quotes around it, it's a literal, not a
column reference ... and whatever one might think about 'id', it's
certainly not an integer.
