Thanks. I tried Data::Dumper and here's the output:

<br>
use Data:: Dumper;
<br>
print Dumper $dbh;   <i>###This displays $VAR1 = bless( {}, 'DBI::db' 
+); -does this mean DB connection was established? (do need an answer 
+here)</i>
<br>
print $rows; <i>###This displays ARRAY(0x1ed0ad8)</i>
<br>
print Dumper $rows; <i>### This displays $VAR1 = []; which means the a
+rray reference is empty-but why?</i>
<br>

I also tried fetchrow_hashref():

my $rows=[];
    $sth = $dbh->prepare( $SQL );
    $sth->execute();
    
    push @{$rows}, $_ while $_ = $sth->fetchrow_hashref();
    
    print Dumper $dbh; #Prints $VAR1 = bless( {}, 'DBI::db' ); 
    print Dumper $sth;#Prints $VAR1 = bless( {}, 'DBI::st' ); 
    print Dumper $rows; #Prints $VAR1 = [];

Same problem. Surprisingly, if you look at the code in my previous posts, I used selectcol_arrayref successfully in the retrieveFormData function so the DB connection seems to be fine. What could possibly be wrong?
