Agreed - but the kicker is, I seem to be the first person in the
known (== Google :-) ) world to have stumbled across this. Is it
due to some sort of setting in the Sybase server (which I don't
control, I'm not the DBA) that causes it to return this long
float answer which fails the matching test?
I'll try your test code to see if I can massage exec.t into
playing nice so I can get DBD-Sybase to install - I've got
other fish to fry with this new Perl 5.8.7 setup I'm trying
to add DBD-Sybase and DBD-Oracle to.
(Ravikumar, good suggestion - I'm just nervous that if this
one test fails, then something else might be broken in actual
DBD-Sybase usage. So I'm trying to get to the bottom of this.)
