in reply to DBD::Sybase prepare statement returns empty query hash but no errstr

OT, not even Sybase cares about newlines so there's no need to bend over backwards with all those quotes and dots.

 my $query = $db->{dbh}->prepare( "
declare \@skiprows int, \@getrows int;
select \@skiprows = $skiprows;
select \@getrows = $getrows;

set rowcount \@skiprows;
select * into #debt from debt
order by debt_id, debt_no asc;

set rowcount \@getrows;
select * from debt where
(debt_id NOT IN ( select * from #debt ) )
ORDER BY debt_id, debt_no ASC" );

    I use a similar syntax for lining up my source code:

    my $st = $dbh->prepare
  (q[SELECT foo, bar, baz FROM whatever]
  .q[    WHERE foo = xyz AND bar IS NOT NULL AND ...]);

      The thing is there's no need to close and reopen the string literal. You are working too hard and if you then need to copy&paste the SQL elsewhere you have to work again.

      my $st = $dbh->prepare(q[
  SELECT foo, bar, baz
    FROM whatever
   WHERE foo = xyz AND bar IS NOT NULL AND ...
]);

        You do have to close and reopen the literal if you want Emacs to indent your code properly. Emacs indentation commands will not change multi-line string constants.
