ober Posted May 22, 2006 Share Posted May 22, 2006 The "AS" part creates an alias.So when you echo a field, you want to use the alias name instead of the actual field name (the part after the "as").echo $album['Picture']; Link to comment https://forums.phpfreaks.com/topic/10202-sql-question/#findComment-38016 Share on other sites More sharing options...
mojito Posted May 22, 2006 Author Share Posted May 22, 2006 Thanks ober, thats really useful, butI can see that "a" is later said to be album and "p" is said to be pictures but the bit I also dont get is the "l" or "1" here..[code]pictures l where a.aid = p.aid and a.pid = p.pid and a.aid = l.aid group by a.aid[/code]thanks for sharing your knowledge with us.
