Actually if you think about it, it makes sense. At least from the
example you provide.
insert into x values(5) is a integer insertion, and it just inserts into
the first column but
the second example insert into x values() specifies a blank value. A
blank is a string
(versus a NULL which is nothing) and the parser barfs on it with an
integer. Although
you will get a different error, insert into x values ('') will also fail.
Sincerely,
Joshua Drake
