Hello, I am using PostgreSQL 6.3 and PHP. I am trying to build a query that
only returns 20 results at a time, with a "next" link at the bottom of the
query results for the next 20. Someone suggested to me that I use the below
block of code (pg_Exec ($conn, "set QUERY_LIMIT='20'");). How would I use
this in the below code I'm already using to connect to and query the DB? And
does anyone maybe have any better ideas of going about this task?
CODE I WAS GIVEN TO USE
---------------------------------------------------------------------
pg_Exec ($conn, "set QUERY_LIMIT='20'");
---------------------------------------------------------------------
THE CODE I AM USING NOW
---------------------------------------------------------------------
<SCRIPT language="PHP">
$conn = pg_Connect("Localhost", "5432", "", "", "contacts");
if (!$conn) {
echo "An error occurred.\n";
exit;
}
$result = pg_Exec($conn, "SELECT* FROM contacts_list");
if (!$result) {
echo "An error occurred.\n";
exit;
}
$num = pg_NumRows($result);
$i = 0;
while ($i < $num) {
echo "<TR><TD><font>";
echo pg_Result($result, $i, "personal_id");
echo "</font></TD><TD><font>";
echo pg_Result($result, $i, "name");
echo "</font></TD><TD><font>";
echo pg_Result($result, $i, "address");
echo "</font></TD><TD><font>";
echo pg_Result($result, $i, "city");
echo "</font></TD><TD><font>";
echo pg_Result($result, $i, "state");
echo "</font></TD><TD><font>";
echo pg_Result($result, $i, "zip_code");
echo "</font></center></TD><TD><center><font>";
echo pg_Result($result, $i, "phone_number");
echo "</font></center></TD></TR>";
$i++;
}
pg_FreeResult($result);
pg_Close($conn);
</script>

Thank you everyone for your help
