MS SQL JSON类型type

在MS SQL Server 2016，已经支持JSON处理。

执行下面代码，将获取ms sql server对象类型以及其说明:

 

IF OBJECT_ID('tempdb.dbo.#json_type') IS NOT NULL DROP TABLE #json_typeCREATE TABLE #json_type (    [type] TINYINT,[data_type] NVARCHAR(30)
)
INSERT INTO  #json_type ([type],[data_type]) VALUES 
(0,'null'),
(1,'string'),
(2,'int'),
(3,'true/false'),
(4,'array'),
(5,'object')SELECT [type],[data_type] FROM #json_type

 
把它写成一个自定义函数：

 

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
