SQL Server DISTINCT

Question

SELECT dbo.CLIENTREP.ref, dbo.REP2.ref
  FROM dbo.CLIENTREP 
  FULL OUTER JOIN dbo.REP2 ON (dbo.REP2.ref = dbo.CLIENTREP.ref)
    WHERE dbo.REP2.ref is null OR dbo.CLIENTREP.ref IS NULL;

Как указать, что возвращаются только DISTINCT dbo.CLIENTREP.ref и dbo.REP2.ref?

Answer 1

Просто напишите SELECT DISTINCT ...

SELECT distinct dbo.CLIENTREP.ref, dbo.REP2.ref
FROM dbo.CLIENTREP 
FULL OUTER JOIN dbo.REP2 ON (dbo.REP2.ref = dbo.CLIENTREP.ref)
WHERE dbo.REP2.ref is null OR dbo.CLIENTREP.ref IS NULL;
