The following code executes a lengthy (time consuming) stored procedure.

#!perl

use strict;
use DBI;

$|=1;

my %INI;
$INI{DSN} = 'Casinfo-SQL';
$INI{DBuser} = 'sa';
$INI{DBpass} = 'diamond';

my $dbh;                        # database filehandle
my $stmt;

my $userid = 1;

print "before connect\n";
if ( $dbh = DBI->connect("DBI:ODBC:$INI{DSN}",$INI{DBuser},$INI{DBpass
+}) ) {
   $dbh->{AutoCommit} = 0;  # enable transactions, if possible
   $dbh->{RaiseError} = 1;
   print "connected\n";
   eval {
      my $stmt = "exec sp3PTSdrawing $userid";
      print "before |$stmt|\n";
      my $success = sDB_EXEC($stmt,$dbh);
      $dbh->commit;
      print "commited\n";
   };
   if ($@) {
      warn "Transaction aborted because $@";
      eval { $dbh->rollback };
      print "rolled back\n";
   }
   $dbh->disconnect();
   print "disconnecting\n";
} else {
   print "ERROR:Could not connect to database (ODBC DSN) |$INI{DSN}| $
+DBI::errstr \n";
} # end if ( $dbh = DBI->connect("DBI:ODBC:$INI{DSN}",$INI{DBuser},$IN
+I{DBpass}) )

sub sDB_EXEC {

   my $dbh = $_[1];
   my $debugthreshhold = 2;
   my $rc; # record count of lines inserted

      print "IN sDB_EXEC: $stmt RETURNS $rc\n";
   } else {

When

exec sp3PTSdrawing 1
[download]

is executed from the Query Analyzer the procedure takes between 30 seconds and 2 minutes. It completes with lots of records being written to a table.
 
When the perl program is executed from the command prompt it takes about 8 seconds. The output of the program is as follows:

before connect
connected
before |exec sp3PTSdrawing 1|
IN sDB_EXEC: exec sp3drawing 1 RETURNS 1
commited
disconnecting
[download]

However, the resulting set of records is incomplete. It is as if the execution timed out but was still deemed OK. The partial record set is committed to the database.
 
In reading through the DBI there is code to allow the user to abort a transaction, but I don't see code to set maximum timeout limits. I thought it might be an ODBC timeout, but I see no timeouts in the ODBC setup, plus I have long running queries in perl scripts on this server (longer than 30 seconds).
 
Advice would be greatly appreciated.
