One shouldn't reply from work when you don't take the time to read the
request completely... I obviously got this wrong the first time around.

Anyway - here's what happens:

When $sth->execute() sees the error it cancels the batch because the result
set that causes the error isn't a result set that returns any rows.
You can verify this with a DBI->trace():

    DBI 1.46-ithread default trace level set to 0x0/4 (pid 18035)
    Note: perl is running without the recommended perl -w option
    -> execute for DBD::Sybase::st (DBI::st=HASH(0x8200c20)~0x8200c08) thr#804bd00
    servermsg_cb -> number=208 severity=16 state=1 line=1 server=DBA_SQL procedure=test1 text=#temp not found. Specify owner.objectname or use sp_help
 to check whether the object exists (sp_help may produce lots of output).

    st_next_result() -> ct_results(4043) == 1
    ct_res_info() returns 1 columns
    ct_describe(0): type = 8, maxlen = 4
    describe() -> col 0, type 8, realtype 8
describe() retcode = 1
    st_next_result() -> lasterr = 208, lastsev = 16
    st_next_result() -> restype is not data result or syb_cancel_request_on_error is TRUE, force failFlag
    st_next_result() -> failFlag set - clear request
    clear_sth_flags() -> resetting ACTIVE, moreResults, dyn_execed, exec_done
    clear_sth_flags() -> reset inUse flag
    st_next_result() -> force CS_CMD_FAIL return
    st_next_result() -> got CS_CMD_FAIL: resetting ACTIVE, moreResults, dyn_execed, exec_done
    clear_sth_flags() -> resetting ACTIVE, moreResults, dyn_execed, exec_done
    clear_sth_flags() -> reset inUse flag
    !! ERROR: 208 'Server message number=208 severity=16 state=1 line=1 server=DBA_SQL procedure=test1 text=#temp not found. Specify owner.objectname
or use sp_help to check whether the object exists (sp_help may produce lots of output).
' (err#0)

All this means that the status code is never returned in this situation.

I suppose it might be argued that this isn't the right behavior...

Subject:    stored procedure and return values


hi all

i have some trouble to get the return value from a stored procedure..
hopefully someone of you is able to help me. the procedure i used for
testing:


create table #test
(
 test int
)
go
create proc proctest
as
begin
  select * from #test
end
go
drop table #test
go
exec proctest


when i run the procedure proctest with isql the return status is -6.

i try to catch this in perl but i can't get it.. i used different ways
and this is the latest one - based on the documentation:

#!/usr/bin/perl

$ENV{SYBASE}="/apps/sybase/current";
$ENV{SYBASE_SYSAM}="SYSAM-1_0";
$ENV{SYBASE_FTS}="EFTS-12_5";
$ENV{SYBASE_JRE}="/apps/sybase/current/shared-1_0/jre1.2.2";
$ENV{SYBASE_ASE}="ASE-12_5";
$ENV{SYBASE_OCS}="OCS-12_5";

use DBI;
use DBD::Sybase;

my $dbuser = "user";
my $dbpass = "password";

$dbh_dst = DBI->connect("dbi:Sybase:server=SERVER",
                          $dbuser, $dbpass, {
                                   RaiseError => 0,
                                   PrintError => 1,
                                   AutoCommit => 1
                                 })        or die "Can't connect to
database: ", $DBI::errstr, "\n";


$sth_dst = $dbh_dst->prepare("exec dwh_trash..proctest") or die "ERR";

$sth_dst->execute();# or die "ERR";

do
{
  while($data = $sth_dst->fetch)
  {
    if($sth_dst->{syb_result_type} == CS_STATUS_RESULT)
    {
      $status = $data->[0];
      print "if @$data\n";
    }
    else
    {
      print "else @$data\n";
    }
  }
}
while($sth_dst->{syb_more_results});


print "end\n";


it seems that i don't get any data for the result type CS_STATUS_RESULT
as the output is only:

../test.pl
DBD::Sybase::st execute failed: Server message number=208 severity=16
state=1 line=4 server=SERVER procedure=proctest text=#test not found.
Specify owner.objectname or use sp_help to check whether the object
exists (sp_help may produce lots of output).
end of proc


has someone an idea what i do wrong? it seems i'm going mad..


thanks a lot in advance
