Re: Weird join needs
Currently I have a query that is able to return (doing a left join): 'A', 'B', 'E' 'A', 'B', 'F' 'C', 'D', NULL But I need this: 'A', 'B', 'E,F' 'C', 'D', NULL Can SQL help me in any way here ? or do I have to do it by programming ? If you use MySQL 4.1 or later take a look at http://dev.mysql.com/doc/mysql/en/group-by-functions.html and read the part about GROUP_CONCAT()...

Weird join needs
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm in need of doing the following. I have a table, let's say, with a record like this: 1, 'A', 'B'. 2, 'C', 'D' And then I have another table with records like this: 1, 'E' 1, 'F'. Currently I have a query that is able to return (doing a left join): 'A', 'B', 'E' 'A', 'B', 'F' 'C', 'D', NULL But I need this: 'A', 'B', 'E,F' 'C', 'D', NULL Can SQL help me in any way here ? or do I have to do it by programming ?
