So this is the final code I've got, but it doesn't read into college_id as it should be. Thanks! my (@colleges) = ();
while (my @ary = $mysth->fetchrow_array()){
push(@colleges, @ary); # @ary is a reference
$i++;
}
$mysth->finish();
$college_id;
$i = 0;
foreach(@colleges){
# print "colleges: ", @{colleges->$i},"\n";
$college_id=@{colleges->$i};
$i++;
print "college id: ", $college_id, "\n";
$myQuery = "select d.departmentName from Colleges c join Departments d on c.college_id=d.college_id where c.college_id='$college_id'";
$deptsth = &exeQuery($mydbh, $myQuery);
$j=0;
while (my @ary = $deptsth->fetchrow_array()){
push(@departments, @ary); # @ary is a reference
print "departments: ", @{departments->$j}, "\n";
$j++;
}
}
