  I'm sure that you have some ID for each person that would work as a primary key. That's the reason I added it to the example.

  You just need to unpivot the data and one way to do it is by using the APPLY operator.

  Check this and ask questions that you might have.

  CREATE TABLE #TEST (SomeoneID int, OptinEMAILCitadium INT,OptinSMSCitadium INT)

  INSERT INTO #TEST

  SELECT 1,1,0

  UNION ALL

  SELECT 2,0,1

  UNION ALL

  SELECT 3,1,1

  UNION ALL

  SELECT 4,0,0

  UNION ALL

  SELECT 5,1,0

  SELECT SomeoneID,

  OptinEMAILCitadium,

  OptinSMSCitadium,

  ISNULL( [Type], 'None') AS [Type]

  FROM #TEST

  OUTER APPLY(SELECT 'Email' AS [Type]

  WHERE OptinEMAILCitadium = 1

  UNION ALL

  SELECT 'SMS'

  WHERE OptinSMSCitadium = 1) AS unpiv

  --ORDER BY SomeoneID;

  GO

  DROP TABLE #TEST

  Perfect Luis, Many Thanks.

  We do have a memberID key column.

  Can you please explain about Apply operator how does it works? Just in a simple words.

  Thnx again.
