Have you tried using Google?

• DBI
• fetchall_arrayref

Or just go and read the DBI documentation directly:

DBI or type perldoc DBI at your command prompt.

Thanks for that insight. Refering back to my post above, "will fetchall_arrayref affect clobs?".... I have tried the following code:

sub get_all_data{
    my $max_rows = 5000;

    while (my $aref = $sth2->fetchall_arrayref(undef, $max_rows))
    {
        $struct = $dbh_ideas->ora_lob_read(@$aref[1],1,65536);
        push @$raResults, [ $aref[0],$struct ];
    };

return $raResults;
}
[download]

Then later:

  $p = Project->new_project($id);
  $cursor = $p->get_all_data;

foreach my $row (@$cursor){
    print OUTPUT do{
        local $" = qq{\t};
        qq{$row->[1]\$\$\$\$\n};
        } if defined $row->[1];
}
[download]


My output file doesnt get written, but equally doesnt die either. I get a "locator is not of type OCILobLocatorPtr at Project.pm line 146." error message. It is something to do with ora_lob_read - does anyone know the syntax for this situation? Thanks

Curiously enough, this exact error message is mentioned in DBD::Oracle. As I don't have Oracle myself, I can't be of much more assistance, but maybe Google can help you better, if the documentation doesn't.

While I do lack knowledge with Oracle and obviously your system/implementation - I don't get it why don't you just do something like:

sub get_all_data{
    return $sth2->fetchall_arrayref();
}

$p = Project->new_project($id);
$cursor = $p->get_all_data();

$| = 1; # to turn on autoflush (turn off print/output cashing)

foreach my $row (@$cursor){
    print OUTPUT do{
        local $" = qq{\t};
        qq{$row->[1]\$\$\$\$\n};
        } if defined $row->[1];
}
[download]

The part inside do{} is something I see for the first time, so I'm not sure if you are trying to output a TAB separated file? In particular I'm not sure what does "qq{$row->[1]\$\$\$\$\n};" do?

Also speaking in general - mixing OOP (Project.pm ...etc) and non-OOP (global $sth2 value) is usually not a good thing. IMHO you should keep consistency - pick one and stick with it.
