    Execute SQL satatements in perl using DBI execute method

    hi i am new in perl and i am trying to query a table in oracle db. I would like for help in debgging my script. I've tried executing the same SQL statement in TOAD and it works just fine, but when I try to execute it using perl no rows are being returned. Below is the code

    $SQL = "SELECT $columns FROM $tbl WHERE $col_cond $val_cond AND $date_col <= SYSDATE - NUMTODSINTERVAL($ll,'HOUR') AND $date_col >= SYSDATE - NUMTODSINTERVAL($ul,'HOUR')";

    my $sth = $dbh->prepare($SQL) or die "prepare failed: ". $dbh->errstr();
    $sth->execute;

    while (row = $sth->fetchrow())
    {
    $line = join(",", row), "\n";
    print "$line\n";
    }
    $sth->finish();


    Thank you in advance for the help
