SQL-Abfrage für Datenbank auf Microsoft SQL-Server

Question

Meine Abfrage funktioniert überhaupt nicht und arbeitete, um zu sehen, was falsch ist, aber nicht finden kann. sagt, dass zwei Werte haben, die gleich sind, aber ehrlich meinen Code Ich tue mein Bestes, um korrekturgelesen:

Wie Sie alle Tabellen sehen und Werte beziehen und verbunden mit inneren und äußeren verbindet die Ergänzung Tabellen. Es ist für einen Bericht

Answer 1

Ihre Abfrage hat mehrere Probleme.

1) Problem with parenthese (too '(') 
2) You use left outer join on table and you test a zone of this table -> null will be excluded like it 
3) Multiples Zones in your select with same name 
4) Quotes for zones and alias for tables are not necessary
