# create a callback subroutine to generate the data to be paged
my $get_data_sub = sub {
my ($offset, $rows) = @_;
my @return_array;
for (my $x = 0; $x < $rows; $x++) {
push(@return_array, [ $row ]);
}
return \@return_array;
}
Now this is just the stub function frrm the example in the documentation. You don't want that to return a few numbers here, but real data from your database.
So you have to change your callback function:
my $get_data_sub = sub {
my ($offset, $rows) = @_;
my @return_array;
# Prepare SQL query:
my $sth = $dbi->prepare("Your SQL here that fetches the data from
+ $offset to $offset+$rows");
$sth->execute($offset, $rows);
while (my $array_ref = $sth->fetchrow_arrayref){
push @return_array, $array_ref;
}
return \@return_array;
}
The only thing that's left for you now is to figure out your SQL (a small hint: use placeholders as explained in the DBI documentation).
