To save JSON array data supplied as a parameter in a stored procedure and insert it into a table, you'll need to write stored procedures in a programming language supported by your database. I'll use SQL Server's T-SQL language as an example, but the concept may be applied to other database systems with minor changes.
Assume you have a table named MyTable with three columns: ID, Name, and Data. You wish to use a stored procedure to pass a JSON array as a parameter and insert each element of the JSON array into the MyTable table.
Here's an example of how to do this in SQL Server using a stored procedure.
-- 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
Create a table MyTable to store the data.
Create a stored procedure InsertJsonData that takes @jsonData as a parameter, which should be a JSON array.
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.
