Subquery as another field

Question

I have trying to do a SELECT query....not an UPDATE or INSERT or DELETE.

I have three tables.

• The customers table
• The invoices table
• The invoice_items table

I want to run a query that will show me every invoice. Each invoice can have only ONE customer and MANY items...hence the existence of invoice_items

My current query looks like this

SELECT i.order_date, c.name, thedata.info from invoices i inner join customers c ON (i.customer = c.id) right join ( select x.order, group_concat( concat(x.itemname,' ', x.itemdesc) separator "\n" ) as info from invoice_items x ) thedata on (i.id = thedata.order)

When I run this query, I receive one row that contains, one customer, one invoice, and a list of any an every item regardless of invoice id or customer...???

+---------------------+--------------+---------------------------------------------------------------------------------------------------------------------------------+
| order_date          | name         | info                                                                                                                            |

My goal is to receive this same list but show all customers along with THEIR items. What am I doing wrong?

Here are the schemas, for those that need them.

Answer 1

try the below query, you need to use GROUP BY if you use GROUP_CONCAT().

SELECT i.order_date,
       c.name,
       group_concat( concat(x.itemname,' ', x.itemdesc) separator "\n" ) as info
FROM invoices i 
INNER JOIN customers c ON i.customer = c.id
LEFT JOIN invoice_items x ON i.id = x.order
GROUP BY i.order_date,c.name
