FOR XML PATH('') 的簡單使用

select  Name + ','  from  A  FOR XML PATH('')

若 Name不是 varchar類型，先轉

select  CAST(Name AS varchar) + ','  from  A  FOR XML PATH('')

去，號

select left(a,len(a)-1) from  (select  (select  CAST(Name AS varchar) + ','  from A FOR XML PATH('')) a)b

---

 

 接下來我們利用STUFF結合FOR XML PATH來拼接JSON字符串，如下

DECLARE @content VARCHAR(MAX)

SET @content = (SELECT '['+ STUFF((SELECT TOP 5 ',{"ID": "' +  CONVERT(VARCHAR, ID) + '","Years": "' + CONVERT(VARCHAR, Years) + '","Name": "' + CONVERT(VARCHAR, Name) + '","ZipCode": "' + CONVERT(VARCHAR, ZipCode, 105) + '"}' FROM CMS_InfoPublish_N_ServiceObject_Type_People 
 FOR XML PATH('')), 1, 1,''
 ) 
 + ']')

PRINT @content
