Hi All,

I try to use the DBD-ODBC GetPrimaryKeys function. But I don't understand what is 
the $Catalog, $Schema stands for ? And How do I use them ?

Please give me a hand.


    sub GetPrimaryKeys {
                        my ($dbh, $Catalog, $Schema, $Table) = @_;
                        # create a "blank" statement handle
                        my $sth = DBI::_new_sth($dbh, { 'Statement' => 
"SQLPrimaryKeys" });
                        _GetPrimaryKeys($dbh, $sth, $Catalog, $Schema, $Table) or 
return undef;
                        $sth;
    }
