SQL with Manoj

In my [previous post] I discussed on how to format/convert any Query/Table data to a string in JSON format. JSON in SQL Server was limited to this feature only till the CTP 2 version.

But now with the CTP 3 release you can do reverse of it also, means now you can read back JSON data and convert it to tabular or row & column format.
 

Let’s check this by taking same sample data from our previous JSON-Export post.

DECLARE @json NVARCHAR(1000)
SELECT @json = N'{"StudList":
[  
   {  
      "ID":1,
      "FirstName":"Manoj",
      "LastName":"Pandey",
      "Class":10,
      "Marks":80.5
   },
   {  
      "ID":2,
      "FirstName":"Saurabh",
      "LastName":"Sharma",
      "Class":11,
      "Marks":82.7
   },
   {  
      "ID":3,
      "FirstName":"Kanchan",
      "LastName":"Pandey",
      "Class":10,
      "Marks":90.5
   },
   {  
      "ID":4,
      "FirstName":"Rajesh",
      "LastName":"Shah",
      "Class":11,
      "Marks":70.3
   },
   {  
      "ID":5,
      "FirstName":"Kunal",
      "LastName":"Joshi",
      "Class":12,
      "Marks":64.7
   }
]'

SELECT ID, FirstName, LastName, Class, Marks
FROM OPENJSON (@json, '$.StudList')
WITH (
	ID INT, 
	FirstName VARCHAR(255), 
	LastName VARCHAR(255), 
	Class INT,
	Marks DECIMAL(3,1)
) AS StudList

– Output:

Well, that was simple, isn’t it!!!
 

In my [next post] I’ll talk about Nested Properties in a JSON string with single and multiple elements.
