Dear Monks, I get this error: 


DBD::mysql::st fetchrow_array failed: fetch() without execute() at que
+ry_B_testing_changes.pl line 35.

For this bit of my Perl code: 


    $dbh=DBI->connect('DBI:mysql:genome', 'u', 'p');
    $sth = $dbh->prepare ("SELECT P.gene_name_M 
            FROM para_n P 
            WHERE P.number_genes_group = 4"); 

    $sth->execute ()

        
    while (@ary = $sth->fetchrow_array ())
    {
    
    foreach (@ary)
    {
#...........rest of code

Can any monks kindly explain why?
