Insert multiple entries into table using procedure in MySQL - mysql

Question

I have created a procedure in mysql to insert into table as below.
DELIMITER $$
CREATE PROCEDURE createOrderPR ( IN iv_productID INT,
IN iv_orderDate DATE,
IN iv_orderTime TIME,
IN iv_shopID INT,
IN iv_mobileNo varchar(10),
IN iv_quantity smallint,
IN iv_total float(10,2),
IN iv_discount float(10,2),
IN iv_taxable float(10,2),
IN iv_CGST float(10,2),
IN iv_SGST float(10,2)
)
BEGIN
DECLARE availQty smallint default 0;
SELECT stockCount INTO availQty FROM product WHERE productID = iv_productID;
SET availQty = availQty - iv_quantity;
start transaction;
set autocommit =0;
INSERT INTO orders(orderNo,productID,orderDate,orderTime,shopID,mobileNo,quantity,total,discount,taxable,CGST,SGST,orderStatus,deletionMark)
VALUES( null,iv_productID,iv_orderDate,iv_orderTime,iv_shopID,iv_mobileNo,iv_quantity,iv_total,iv_discount,iv_taxable,iv_CGST,iv_SGST,'Open',null);
UPDATE product SET stockCount = availQty WHERE productID = iv_productID;
COMMIT;
SELECT MAX(orderNo) FROM orders WHERE shopID = shopID AND mobileNo = mobileNo;
END
$$
Currently it will only allow single record.now I need to insert multiple records in that case how to define the IN parameter of the procedure. Please suggest.

Solved the issue by using the JSON IN parameter these are the sample code (Note:new column added in the table rest all no change)
DELIMITER $$
CREATE PROCEDURE createOrderMulti ( IN orderJson JSON,
IN length INT )
BEGIN
-- Date Declaration
DECLARE availQty smallint default 0;
DECLARE iv_productID INT;
DECLARE iv_orderDate DATE;
DECLARE iv_orderTime TIME;
DECLARE iv_shopID INT;
DECLARE iv_mobileNo varchar(10);
DECLARE iv_quantity smallint;
DECLARE iv_total float(10,2);
DECLARE iv_discount float(10,2);
DECLARE iv_taxable float(10,2);
DECLARE iv_CGST float(10,2);
DECLARE iv_SGST float(10,2);
DECLARE counter smallint default 0;
DECLARE item INT;
DECLARE orderNo INT DEFAULT null;
start transaction;
set autocommit = 0;
WHILE counter < length DO
-- Extract the JSON value
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].productID')) INTO iv_productID;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].orderDate')) INTO iv_orderDate;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].orderTime')) INTO iv_orderTime;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].shopID')) INTO iv_shopID;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].mobileNo')) INTO iv_mobileNo;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].quantity')) INTO iv_quantity;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].total')) INTO iv_total;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].discount')) INTO iv_discount;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].taxable')) INTO iv_taxable;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].CGST')) INTO iv_CGST;
SELECT JSON_VALUE(orderJson, CONCAT('$[', counter, '].SGST')) INTO iv_SGST;
SELECT stockCount INTO availQty FROM product WHERE productID = iv_productID;
SET availQty = availQty - iv_quantity;
SET item = counter + 1;
INSERT INTO orders(orderNo,item,productID,orderDate,orderTime,shopID,mobileNo,quantity,total,discount,taxable,CGST,SGST,orderStatus,deletionMark)
VALUES( orderNo,item,iv_productID,iv_orderDate,iv_orderTime,iv_shopID,iv_mobileNo,iv_quantity,iv_total,iv_discount,iv_taxable,iv_CGST,iv_SGST,'Open',null);
SET orderNo = LAST_INSERT_ID();
UPDATE product SET stockCount = availQty WHERE productID = iv_productID;
SET counter = counter + 1;
END WHILE;
COMMIT;
--SELECT MAX(orderNo) FROM orders WHERE shopID = shopID AND mobileNo = mobileNo;
SELECT orderNo as orderNo;
END
