Nobody's kicking you out of any group. Someone requested themselves to be removed, with a typo that made it ambiguous.
The original question had nothing to do with INT, it was behavior of CHAR and trailing spaces.

> Is it expected behavior that all 3 rows would be returned (because the space isn’t an INT?)
Yes. Or more precisely, it is because when a string is cast to an int, leading and trailing spaces are ignored. The
alternativewould be to raise an error, as 'an integer plus some spaces' is not an integer...

> -- 1 rows returned.
Yes, for TEXT column, which behaves the same as VARCHAR. Also 1 row for:
select c2 from matt_test2 where c2 = '123 '
But 2 rows returned for CHAR column, as inserting '123' and '123 ' into CHAR(n) results in the same value being
inserted.And also 2 rows returned for:
select c2 from matt_test2 where c2 = '123 '
^^^ which was the original question
