I'm trying to make a diferent worksheet for each company, I don't know ahead of time how many company's it will give. The problem is that the second go around, $sql_query is empty (it says i need to execute it again). The second query takes long enouph that I want to execute it just once and loop through the results several times. (the actual queries are pretty complex I made up simple ones to simplify the post) 
my $query1 = $dbh_bob->prepare(qq{

        SELECT company
    FROM namespace.phonebook 
}

my $sql_query = $dbh_bob->prepare(qq{
        SELECT name, birthdate_date, gender, company
    FROM namespace.directory 
}

$sql_query->execute;
$query1->execute;


while (@data1 = $query1->fetchrow_array())
{ 
    my $cur_company = @data[0]
     $worksheet = $excel->addworksheet($cur_company);
    row = 0;
    while (@data2 = $sql_query->fetchrow_array()){ 
    if (@data2[3] eq $cur_company) 
    {
             $worksheet->write_row($row++, 0, \@data); 
    }
}
