将列的每个唯一值分解为多列，然后显示在单行中

Question

In my actual data I have the following query

SELECT Sales Person,
        (CASE WHEN [ProductType] = 'car' THEN [GOAL_VOLUME]
          END) AS 'car Goal'
    , (CASE WHEN [ProductType] = 'boat' THEN [GOAL_VOLUME]
          END) AS 'boat Goal'
    , (CASE WHEN [ProductType] IN ('bike', 'scooter') THEN [GOAL_VOLUME]
          END) AS 'bike/scooter Goal'
FROM PRODUCT_GOALS

My current results are each Sales Person's name broken out 3 times into 3 rows with each row having only one non-NULL value for the Goal_Volume... I need everything on one row... Might need multiple subqueries to join against for each product? See image below.

Thanks for the help

You can use conditional aggregation:

SELECT [Sales Person]
    , MAX(CASE WHEN [ProductType] = 'car' THEN [GOAL_VOLUME]
          END) AS 'car Goal'
    , MAX(CASE WHEN [ProductType] = 'boat' THEN [GOAL_VOLUME]
          END) AS 'boat Goal'
    , MAX(CASE WHEN [ProductType] IN ('bike', 'scooter') THEN [GOAL_VOLUME]
          END) AS 'bike/scooter Goal'
FROM PRODUCT_GOALS
GROUP BY [Sales Person]

Almost the same query as yours, just added MAX and GROUP BY .
