I use PHP, and I want to get a customer list and transaction times between 2015-01-01 till 2015-01-03
the result should be

2 | B01 | BCD | 1
3 | C01 | CDE | 2
Please help. I want to use Store Procedure on MySQL, and I dont want to loop it in PHP.

Answer 1

To get the info you use a group by statement:
SELECT a.id,a.registration_code,a.full_name, COUNT(*) as n_trans
FROM customers a
INNER JOIN history_transaction b
ON a.id=b.customer_id
WHERE b.transaction_date BETWEEN "{start_date}" AND "{end_date}"
GROUP BY a.id,a.registration_code,a.full_name;
You can set start_date and end_date dynamically using mysqli (a php module for working with MySQL from php).

Answer 2

This is the way to create stored procedure in MySQL:
CREATE PROCEDURE find_transaction_detail()
BEGIN
SELECT a.id,a.registration_code,a.full_name, COUNT(*) as n_trans
FROM customers a
INNER JOIN history_transaction ON a.id=b.customer_id
WHERE b.transaction_date BETWEEN "{start_date}" AND "{end_date}"
GROUP BY a.id,a.registration_code,a.full_name;
END;
Way to find result:
CALL find_transaction_detail ();
