Hello i work on one project using JS, PHP & Mysql. I have 2 tables which are :
invoice (inv_id,date,total,paid,due)
invoice_infos (id, product_name,product_price,inv_id)
invoice_infos contains informations about all products of a invoice.
The column date
of table invoice
contains the date of the invoice, the column product_name
of invoice_details
contains name of product.
I want do a query which allow me view product selled in defined date.
You seem to be looking for a simple JOIN
between both tables, using field inv_id
. The FROM
clause of your queries should look like :
FROM invoices iv
INNER JOIN invoice_infos if ON if.inv_id = id.inv_id
Starting from there, say you want to pull out all available information in invoice_infos
and invoices
for a specific date of sale :
SELECT iv.*, if.*
FROM invoices iv
INNER JOIN invoice_infos if ON if.inv_id = id.inv_id
WHERE iv.date = ?
Another typical use case is to aggregate date. For example let's compute the total price for each product sold on a given date :
SELECT if.product_name, SUM(if.product_price) sum_product_price
FROM invoices iv
INNER JOIN invoice_infos if ON if.inv_id = id.inv_id
WHERE iv.date = ?
GROUP BY if.product_name
