我试图做一个SELECT查询....不是更新或INSERT或DELETE。子查询作为另一个字段
我有三张桌子。
- Customers表
- 发票表
- 的invoice_items表
我想运行一个查询会告诉我每张发票。每张发票只能有一个客户和许多项目...。因此invoice_items
我当前的查询看起来像这样
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)
当我运行此查询,我收到一封包含一个行,一个客户存在,一张发票,以及任何每件商品的清单,无论发票编号或客户... ???

我的目标是收到这个相同的列表,但显示所有客户以及他们的项目。 我在做什么错?
这里是模式,为那些需要他们。

非常感谢!这工作完美无瑕。它只需要一个HAVING子句'HAVING info IS NOT NULL'。现在我可以继续这个项目。 – dockeryZ
