Question

Can someone give example how to pass JSON type as parameter to SQL Server 2016 stored procedure using ADO.Net in C# ASP.Net Core Web Api project ? I want to see example of SQL

Answer 1

There is no json data type in sql sever you can simply send your json as varchar to stored procedure.

If you want to map your json to table you can use use OPENJSON to convert data to rows and columns.

CREATE PROCEDURE SaveJSON
@pID int,
@pJson nvarchar(max)

AS
BEGIN

INSERT INTO [YourTable]
       ([ID]
       ,[JSONData])
 VALUES
       (@pID
       ,@pJson)
END

If you want to map json objects with table you can do this

//json would be something like this
[
 { "id" : 2,"name": "John"},
 { "id" : 5,"name": "John"}
]

INSERT INTO YourTable (id,Name)
SELECT id, name
FROM OPENJSON(@pJson)
WITH (id int,
name nvarchar(max))

Here is a very good and detailed article which will give you detailed idea to deal with json data
