Hi all, I have 2 tables that I need to extract data from, say PORTS and STATS. PORTS contains a list of Sea Ports in PORT i.e. : - PORTS.PORT -------------------- UK FRANCE GERMANY NETHERLANDS SPAIN ITALY STATS contains a few thousand records that with among other things has the elements TO_PORT and AMOUNT. the entries in TO_PORT match the ports in PORT. Now one of the things I want to do is produce a summary of the totals of AMOUNT against the ports in PORTS, including (and this is the important bit that I'm stuck on) the ports in PORTS that do not have a match in STATS.TO_PORT. so that I get a result such as : - UK 300 FRANCE 100 GERMANY 400 NETHERLANDS 0 SPAIN 0 ITALY 300 and NOT :- UK 300 FRANCE 100 GERMANY 400 ITALY 300 Which is all I can get at the moment. the query I am using is : - SELECT PORTS.PORT, SUM(STATS.AMOUNT) FROM PORTS LEFT JOIN STATS ON PORTS.PORT = STATS.TO_PORT GROUP BY PORTS.PORT Basicaly what I want to do is pull out a list of all entries in PORTS.PORT and put a total figure against it from STATS.AMOUNT where the STATS.TO_PORT matches PORTS.PORT and just a zero if theres no entry in STATS. Anyone got any ideas? Thanks Dan -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
