Hi,

I have some code which should return ~5000 rows (2 columns) (as a reference to an array) from an Oracle database. To execute this PLSQL query takes ~1 second in TOAD or SQLDeveloper however in Perl, using the DBI and DBD::Oracle drivers, it takes just over half an hour. As far as I know, bind_columns is the most efficient way of retrieving data, but maybe you guys could suggest other ideas?

my $plsql=<<ENDPLSQL;
    DECLARE
  l_header pacProject.data_header_cur;
  l_data   pacProject.data_cur;
  l_project_id NUMBER;
  l_design_set_id NUMBER;
  l_layout_id NUMBER;
BEGIN
  l_design_set_id := NULL;
  l_layout_id := 1;
  pacProject.get_data(
    :l_project_id,
    l_design_set_id, 
    l_layout_id,
    l_header,
    :l_data);
END;
ENDPLSQL
    my $sth_ideas = $dbh_ideas->prepare($plsql);
    my $sth2;
    my @row;
    $sth_ideas->bind_param(":l_project_id",$self->{project_id});
    $sth_ideas->bind_param_inout(":l_data",\$sth2,0,{ora_type => ORA_R
+SET});
    $sth_ideas->execute;
    my $raRow;
    my $raResults = [];
    my ($id, $valreal, $valtext, $colorder);
    $sth2->bind_columns(\($id, $valreal, $valtext, $colorder));
    while( $sth2->fetch )
    {
        
        push @$raResults, [ $id,$valtext ];
    }
    return $raResults;

Thanks.
