Select A.*,B.* from A left outer join B on x in (subselectA) and y in (subselectB) Union all Select A.*,B.* from B left outer join A on x in (subselectD) and y in (subselectC)
It seems strange that there is no condition limiting which rows from A and B match, which makes the LEFT OUTER JOIN rather pointless... -----Ursprüngliche Nachricht----- Von: Jean-Christophe Deschamps [mailto:j...@antichoc.net] Gesendet: Montag, 27.

Dear list, I'm trying to find the correct syntaxt for this, but I hit a syntax error each time: either SQLite shokes on outer parenthesis or on union all. ( select * from A where x in (subselectA) left outer join select * from B where y in (subselectB) ) union all ( -- <-- error select * from B where y in (subselectC) left outer join select * from A where x in (subselectD) ) Union [all], except, intersect don't seem to accept parenthesis around the left or right parts. Of course a workaround could be to create two views then union all them, but there must be a way to express this construct in a single statement. I don't want the statement to be interpreted this way: select * from A where x in (subselectA) left outer join ( select * from B where y in (subselectB) union all select * from B where y in (subselectC) ) left outer join select * from A where x in (subselectD) -- jcd _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users -------------------------------------------------------------------------- Gunter Hick Software Engineer Scientific Games International GmbH Klitschgasse 2 – 4, A - 1130 Vienna, Austria FN 157284 a, HG Wien Tel: +43 1 80100 0 E-Mail: h...@scigames.at This e-mail is confidential and may well also be legally privileged.
