Meet the new FAQ. :-)

You're almost certainly seeing spurious CS_STATUS_RESULT result types. 
Try  perldoc DBD::Sybase, looking for syb_result_type.  

We might have fixed this in current CVS, that is, we might be correctly
suppressing the spurious results.  The fix hasn't been widely tested yet,
though, and slightly broke row buffering in db-lib.
