Answer 1

SELECT
UserID,
MAX(CASE WHEN IsManagerFeedback = 'FALSE' THEN Level END) AS UserFeedback,
MAX(CASE WHEN IsManagerFeedback = 'TRUE' THEN Level END) AS ManagerFeedback
FROM
Table1
GROUP BY UserID

看到它在sqlfiddle中工作。

更新：

SELECT
Year,
UserID,
MAX(CASE WHEN IsManagerFeedback = 'FALSE' THEN Level END) AS UserFeedback,
MAX(CASE WHEN IsManagerFeedback = 'TRUE' THEN Level END) AS ManagerFeedback
FROM
Table1
GROUP BY Year, UserID
