Sql server 如何通过TSQL从SQL Server查询生成JSON字符串？

我想知道是否有任何函数或东西可以将SQL select查询结果转换为JSON字符串格式

例如，SQL select查询结果为

current   target
-----------------
  500      1000
  1500     2000

JSON结果：

[{"current":500,"target":1000},{"current":1500,"target":2000}]

任何想法都会有帮助

谢谢。

MS SQL Server 2008架构设置：

DECLARE @TABLE TABLE ([current] INT, [target] INT)
INSERT INTO @TABLE VALUES 
(500   ,   1000),
(1500  ,   2000)


SELECT '[' +  STUFF((SELECT ',{"current":' + CAST([current] AS VARCHAR(30)) 
   + ',"target":' + CAST([target] AS VARCHAR(30)) + '}'
FROM @TABLE
FOR XML PATH(''),TYPE).value('.','NVARCHAR(MAX)'),1,1,'') + ']'

[{"current":500,"target":1000},{"current":1500,"target":2000}] 

查询1：

DECLARE @TABLE TABLE ([current] INT, [target] INT)
INSERT INTO @TABLE VALUES 
(500   ,   1000),
(1500  ,   2000)


SELECT '[' +  STUFF((SELECT ',{"current":' + CAST([current] AS VARCHAR(30)) 
   + ',"target":' + CAST([target] AS VARCHAR(30)) + '}'
FROM @TABLE
FOR XML PATH(''),TYPE).value('.','NVARCHAR(MAX)'),1,1,'') + ']'

[{"current":500,"target":1000},{"current":1500,"target":2000}] 

：

DECLARE @TABLE TABLE ([current] INT, [target] INT)
INSERT INTO @TABLE VALUES 
(500   ,   1000),
(1500  ,   2000)


SELECT '[' +  STUFF((SELECT ',{"current":' + CAST([current] AS VARCHAR(30)) 
   + ',"target":' + CAST([target] AS VARCHAR(30)) + '}'
FROM @TABLE
FOR XML PATH(''),TYPE).value('.','NVARCHAR(MAX)'),1,1,'') + ']'

[{"current":500,"target":1000},{"current":1500,"target":2000}]

您没有指定版本

在SQL Server 2016中，您将能够执行以下操作

SELECT [current], 
       target
FROM YourTable
ORDER BY [current]
FOR JSON AUTO;

还是在副本中？看看这里，我将更新代码以包含内部引号：

+CAST（[target]AS VARCHAR（30））+

到

+'”+CAST（[target]AS VARCHAR（30））+'”
