I can't do it because the first dbh is not closed. I come up with a not so bright way to do it using fetchrow_array(), so now I have two arrays. One will hold an array of colleges while I query each department in the college. It doesn't look gracious, so I will take suggestions for improvement. Thanks a bunch.

my(@colleges)=();
while (my @ary = $mysth->fetchrow_array()){
push(@colleges, @ary); # @ary is a reference
}
$mysth->finish();

$i = 0;
$j = 0;
foreach(@college){
print "colleges: ", @{colleges->$i}, "\n"; $myQuery = "select d.departmentName from Colleges c join Departments d on c.college_id=d.college_id where c.id=$j";
$j++;
$deptsth = &exeQuery($mydbh, $myQuery);
while (my @ary = $deptsth->fetchrow_array())
{ push(@departments, @ary); # @ary is a reference
print "departments: ", @{departments->$j}, "\n";
$i++; }
}
