结合两个具有不同功能的SELECT查询

Question

I have one table for reports. My first select query is that combines all sales tables

SELECT *, ds_sales.id_sales
FROM ds_sales LEFT JOIN
     ds_payment 
     ON ds_sales.id_sales=ds_payment.id_sales LEFT JOIN 
     customer_info
     ON ds_payment.id_customer=customer_info.id_customer INNER JOIN
     ds_salesdetails
     ON ds_salesdetails.id_sales=ds_sales.id_sales
WHERE customer_info.id_customer = '".$_POST["id_customer"]."'

This is the result of the query

and my second query is this, to filter the same sales serial number, since the ds_salesdetails table have many sales serial number

select ds_salesdetails.id_sales, count(*),
       group_concat(ds_salesdetails.id_product)
from ds_salesdetails
having count(*) >= 1

I need to merge them to create a report for customers sales.

Answer 1

Join with the grouped subquery instead of the whole table.

SELECT *, ds_sales.id_sales
FROM ds_sales LEFT JOIN
     ds_payment 
     ON ds_sales.id_sales=ds_payment.id_sales LEFT JOIN 
     customer_info
     ON ds_payment.id_customer=customer_info.id_customer LEFT JOIN
    (SELECT id_sales, count(*) as product_count,
           group_concat(ds_salesdetails.id_product) AS product_list
    from ds_salesdetails
    GROUP BY id_sales) AS grouped ON grouped.id_sales = ds_sales.id_sales
WHERE customer_info.id_customer = '".$_POST["id_customer"]."'
