Question

好的，我已经解决了一半的问题，并且我相信我需要帮助来解决另一半。我能够从一列（TEAMS）中填充几行数据并将其连接成一列，但是，似乎我需要对同一数据集中的另一列执行相同的操作。

这是当前数据集示例：

FIRST | LAST      | YEAR  | ID  | TEAMS
-- -- -- -- -- -- -- -- -- -- -- -- -- 
Chris | Anderson  | 2015  | 176 | 05 White (B)
Chris | Anderson  | 2016  | 176 | 05 Royal (B)
Chris | Anderson  | 2017  | 176 | 05 Royal (B), '08 Gray (B)
Chris | Anderson  | 2018  | 176 | 05 Royal (B), 08 (B)

我需要的是将年份VALUE作为列名，将车队数据作为VALUE，像这样：

FIRST | LAST     | 2015         | 2016         | 2017
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
Chris | Anderson | 05 White (B) | 05 Royal (B) | 05 Royal (B), '08 Gray (B)

这是我现有的产生当前（第一个）数据集的SQL语句。

SELECT DISTINCT TOP 100 PERCENT dbo.Coaches.FirstName, dbo.Coaches.LastName, dbo.Teams.clubYear, dbo.Coaches.CoachID,
STUFF ((   SELECT  ', '+ SUBSTRING(TeamName,14,len(TeamName)) + ' ('+LEFT(gender,1)+')'
         FROM     dbo.Teams ST
         WHERE    ST.CoachID = dbo.Coaches.CoachID AND ST.clubYear = dbo.Teams.clubYear
         ORDER BY clubYear, CoachID
         FOR XML PATH('')), 1, 1, '') AS Teams FROM    dbo.Coaches INNER JOIN
    dbo.Teams  ON dbo.Coaches.CoachID = dbo.Teams.CoachID
WHERE   dbo.teams.teamTypeID = 3
GROUP BY dbo.Coaches.FirstName, dbo.Coaches.LastName, dbo.Teams.clubYear, dbo.Teams.TeamName, dbo.Coaches.CoachID
ORDER BY dbo.Coaches.LastName, dbo.Coaches.FirstName, dbo.Teams.clubYear

如果当前数据集示例是您声明的结果，那么这应该很容易。我将通过在声明的表变量中创建类似的数据集来模拟您的查询。只需将SELECT * FROM @tbl替换为您的声明即可。

DECLARE @tbl TABLE ([FIRST] VARCHAR(100),[YEAR] INT,TEAMS VARCHAR(100));
INSERT INTO @tbl VALUES
 ('Chris',2015,'White (B)')
,('Chris',2016,'05 Royal (B)')
,('Chris',2017,'05 Royal (B), 08 Gray (B)');

-查询将使用您的数据集并将其发送到PIVOT

SELECT p.*
FROM
(
    SELECT * FROM @tbl
) t
PIVOT
(
    MAX(TEAMS) FOR [YEAR] IN([2015],[2016],[2017])
) p;

结果

FIRST   2015        2016            2017
Chris   White (B)   05 Royal (B)    05 Royal (B), 08 Gray (B)
