SQL Server 行转列 列转行操作

1.多行转成一行(并以','分开)

表数据如下图:

查询结果如下图:

 SQL查询脚本:

SELECT addPer, house_code = (STUFF((SELECT ',' + house_code FROM my_demo WHERE addPer = T.addPer FOR XML PATH('')), 1, 1, ''))
FROM my_demo AS T
GROUP BY addPer

　　

 2.一行转为一列

SELECT STUFF((SELECT  ',' + CAST(id AS VARCHAR(10))  FROM(SELECT id FROM myDemo WHERE del = 0 ) a  FOR  XML PATH('')  ), 1,0, '') AS Name
