the point was not to remove something but to take into consideration that there has to be a JOIN on the TestIDs (in this case results doesn't differ because you only have 123 as SomeValue) - and because it's too late/early here is my assumed last correction (see the USING I forgot, if you forget this you will get a Cartesian Product) SELECT DISTINCT t.Year, b.Name, (SELECT SomeValue FROM Test INNER JOIN Test2 USING(TestID) WHERE Year = t.Year AND Name = b.Name) AS SomeValue FROM Test t CROSS JOIN (SELECT DISTINCT Name FROM Test) b ; > possible to remove the rest? > > Again, thanks! > > > > To: sqlite-us...@... > > From: oliver....@... > > Date: Sat, 25 Sep 2010 00:05:11 +0000 > > Subject: Re: [sqlite] Need help with self-join (I think) > > > > sry, > > > > a little mistake - here's the correction: > > > > SELECT DISTINCT t.Year, b.Name, > > (SELECT SomeValue FROM Test INNER JOIN Test2 WHERE Year = t.Year AND Name = > > b.Name) AS SomeValue > > FROM Test t > > CROSS JOIN (SELECT DISTINCT Name FROM Test) b > > ; > > > > > > (results don't differ - in this case!) > > > > Oliver > > > > _______________________________________________ > > sqlite-users mailing list > > sqlite-us...@... > > http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users > > _______________________________________________ > sqlite-users mailing list > sqlite-us...@... > http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users > > _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
