I'm having problems joining 3 tables to provide a 4th table in the correct format. I believe I need a FULL OUTER JOIN but does not give the result that I require.See below: Example 1 Table: Names Table: Friend Name Tel email PostCode Name friend email Jim 1 aa I Dave yes cc Ted 2 bb J Will yes dd Dave 3 cc K Zac yes ff Will 4 dd L Byron yes gg Table: Details Name email Town PostCode John ee A M Zac ff B N Byron gg C O Will dd D L Gary hh E P Ted bb F J Combined table: Result Name Tel email Town PostCode friend Jim 1 aa I Ted 2 bb F J Dave 3 cc K yes Will 4 dd D L yes John ee A M Zac ff B N yes Byron gg C O yes Gary hh E P Example 2 Table: Names Table: Friend Name Tel email PostCode Name friend email Jim 1 aa I Gareth yes ii Ted 2 bb J Tony yes jj Dave 3 cc K Ken yes kk Will 4 dd L Lloyd yes ll Table: Details Name email Town PostCode John ee A M Zac ff B N Byron gg C O Gary hh E P Combined table: Result Name Tel email Town PostCode friend Jim 1 aa I Ted 2 bb J Dave 3 cc K Will 4 dd L John ee A M Zac ff B N Byron gg C O Gary hh E P Gareth ii yes Tony jj yes Ken kk yes Lloyd ll yes -- Sent from: https://www.postgresql-archive.org/PostgreSQL-pgadmin-support-f2191615.html
