MYSQL子查询还是左连接？

我正在做一个小的发票申请，我被困在一个查询，以获得我的发票的总未结金额

一点解释：

我在数据库中有两个表，发票和付款在发票id列上有关联。一张发票可以有多笔付款

我想得到的是所有发票的总未结金额

SELECT
  COUNT( * ) AS count,
  SUM( invoice_amount_total ) AS total,
  (SELECT
     SUM( amount ) AS total
   FROM `invoice_payments`
   WHERE `invoice_id` = s.id) AS total_paid
FROM sales_invoices AS s
WHERE s.administration_id = 3
    AND (`invoice_amount_total` <> (SELECT
                      SUM( `amount` ) AS sum
                    FROM `invoice_payments`
                    WHERE `invoice_id` = s.id)
      OR (SELECT
        SUM( amount ) AS sum
          FROM `invoice_payments`
          WHERE `invoice_id` = s.id)IS NULL)

这是我试过的，但不起作用

支付的总金额不正确，它是最后一张发票的总和，而不是所有发票的总和

SELECT
  COUNT( * ) AS count,
  SUM( invoice_amount_total ) AS total,
  (SELECT
     SUM( amount ) AS total
   FROM `invoice_payments`
   WHERE `invoice_id` = s.id) AS total_paid
FROM sales_invoices AS s
WHERE s.administration_id = 3
    AND (`invoice_amount_total` <> (SELECT
                      SUM( `amount` ) AS sum
                    FROM `invoice_payments`
                    WHERE `invoice_id` = s.id)
      OR (SELECT
        SUM( amount ) AS sum
          FROM `invoice_payments`
          WHERE `invoice_id` = s.id)IS NULL)

有什么想法吗？

样本数据和期望的输出在哪里？什么意思，但它不起作用？是否有错误或只是没有输出/不是所需的输出？对不起，输出不正确。支付的总金额不正确，它是最后一张发票的总和，而不是所有发票的总和。
