SQL Server 2016 introduced the support of JSON and added many new functions in the recent CTP3 version of SQL Server 2016.

Now, we have OPENJSON() to extract JSON data into a tabular format. If you are passing JSON document as an input parameter in Stored Procedure, you can use OPENJSON() to extract the value of JSON parameter.
