Re: Paging results

Paging with PostgreSQL is super easy!
select * from table where (x=y) offset 0 limit 30;
Gives you the first 30 matches, then do
select * from table where (x=y) offset 30 limit 30;
This will give the next 30, super easy!

Here's a sample of how I use it in a script

// Collect offset
$offset = isset($_GET['offset'])?$_GET['offset']:0;
// Now the links for Prev/Next
if ($offset >= 30) echo "|<a
href='/contents.php?".$qs."offset=".($offset-30)."'>Back 30</a>";
echo "|<a href='/contents.php?".$qs."offset=".($offset+30)."'>Next 30</a>";
// Query
$rs = pg_exec($db,"select id,name from stuff order by name offset $offset
limit 30;");
