T-SQL 合并多行数据显示到一行

思路：

自连接，使用For XML Path(‘‘)和STUFF函数

SELECT * FROM STUDENT

Name                      Team
------------------------- -------------------------
Jack                      Team1
Rose                      Team1
Cindy                     Team1
Richard                   Team2
Jenny                     Team2

SELECT
        T1.Team,
        STUFF((
                SELECT 
                    CONCAT(‘/‘,T2.Name)
                FROM
                        STUDENT T2
                WHERE 
                        T2.Team=T1.Team
                FOR XML PATH(‘‘)
            ),1,1,‘‘)
        AS NAMES
FROM 
        STUDENT T1
GROUP BY 
        T1.Team 

Team                      NAMES
------------------------- ---------------------------------------------------------

Team1                     Jack/Rose/Cindy
Team2                     Richard/Jenny
