Insert JSON Array into Table with Stored Procedure Parameter

Introduction

In order to save JSON array data passed as a parameter in a stored procedure and insert it into a table, you'll need to use a programming language that your database supports for writing stored procedures. I'll provide an example using SQL Server's T-SQL language, but the concept can be adapted to other database systems with slight variations.

Let's assume you have a table called MyTable with columns ID, Name, and Data. You want to pass a JSON array as a parameter to a stored procedure and insert each element of the JSON array into the MyTable table.

Here's an example of how you can create a stored procedure to achieve this in SQL Server.

-- Create a table to store the data
CREATE TABLE MyTable (
    ID INT IDENTITY(1,1) PRIMARY KEY,
    Name NVARCHAR(255),
    Data NVARCHAR(MAX)
);

-- Create a stored procedure to insert JSON array data
CREATE PROCEDURE InsertJsonData
    @jsonData NVARCHAR(MAX)
AS
BEGIN
    -- Use OPENJSON to parse the JSON array
    INSERT INTO MyTable (Name, Data)
    SELECT 'ItemName', [value]  -- You can replace 'ItemName' with a specific name or retrieve it from JSON
    FROM OPENJSON(@jsonData)
END;

In this example

  1. Create a table MyTable to store the data.
  2. Create a stored procedure InsertJsonData that takes @jsonData as a parameter, which should be a JSON array.
  3. Inside the stored procedure, we use the OPENJSON function to parse the JSON array and insert each element into the MyTable table.

You can call this stored procedure and pass your JSON array as a parameter like this.

DECLARE @json NVARCHAR(MAX);
SET @json = '[{"value": "Value1"}, {"value": "Value2"}, {"value": "Value3"}]';

EXEC InsertJsonData @jsonData = @json;

Replace the JSON array (@json) with your actual JSON data, and the stored procedure will insert each element into the MyTable table.

Keep in mind that the actual implementation may vary depending on your database system, but the general idea of parsing the JSON array and inserting its elements into a table should be similar across different database systems with JSON support.
