sql server 2008 使用 for xml path 实现类似 oracle 的 concat 函数

1. 列出所有数据

select * from test



2. 合并，带有多余的逗号

SELECT name,

(SELECT value+',' FROM test

WHERE name=A.name

FOR XML PATH('')) AS StuList

FROM test A

GROUP BY name



3. 最终效果

SELECT B.sName,LEFT(StuList,LEN(StuList)-1) as hobby FROM (

SELECT sName,

(SELECT hobby+',' FROM student

WHERE sName=A.sName

FOR XML PATH('')) AS StuList

FROM student A

GROUP BY sName

) B
