Re: [PHP-DB] Re: record pointer
Hi mysql select id,cat from table where cat=(select cat from table where id=51); +-+--+ | id | cat | +-+--+ | 40 | FLK | | 41 | FLK | | 42 | FLK | | 44 | FLK | | 45 | FLK | | 46 | FLK | | 47 | FLK | | 48 | FLK | | 49 | FLK | | 50 | FLK | | 51 | FLK | | 52 | FLK | | 53 | FLK | | 54 | FLK | | 55 | FLK | | 56 | FLK | | 57 | FLK | | 58 | FLK | | 59 | FLK | | 60 | FLK | +-+--+ 20 rows in set (0.02 sec) now I can select the whole cat when I enter an ID that is fine! but the query should stop at id=$id or in other words in the end it should POINT to id=$id in the above example the last record would be the record with id=51 do I need another SELECT here? If I understand that correctly, you only need to add the extra condition to the WHERE clause of the main query. So: SELECT id, name, cat FROM table WHERE cat = (SELECT cat FROM table WHERE id = $ID) AND id = $ID; This should display all rows, before and including the row with the same 'cat' as 'id' has. For your example of $ID = 51 it should display: +-+--+ | id | cat | +-+--+ | 40 | FLK | | 41 | FLK | | 42 | FLK | | 44 | FLK | | 45 | FLK | | 46 | FLK | | 47 | FLK | | 48 | FLK | | 49 | FLK | | 50 | FLK | | 51 | FLK | +-+--+ Niel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Huh? You want before, after and including? So everything? Maybe give us an example of what you want to get out of the query rather than us guessing. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
