不正确的小计和＆amp;在mysql中选择总计

Question

我设法将负面与负面分开了。在sql选择下面的正面，我试图得到小计＆amp;总表示如表格中所示，第三列是正确的结果。

下面是sql select我已经使用但是它将结果返回到上表的第2列并且它不正确。如何获得小计和＆amp;第3栏的总结果

谢谢＆amp;此致

SELECT * FROM
(SELECT
      party AS "Account",
      sum(debit-credit) AS "Balance"
 FROM `tabGL Entry`
 WHERE party_type ="Customer" AND MONTH(posting_date) = MONTH(Now()) -1
 GROUP BY party WITH ROLLUP
 HAVING sum(debit-credit) < 0
 UNION ALL
 SELECT
      party AS "Account",
      sum(debit-credit) AS "Balance"
 FROM `tabGL Entry`
 WHERE party_type ="Customer" AND MONTH(posting_date) = MONTH(Now()) -1
 GROUP BY party WITH ROLLUP
 HAVING sum(debit-credit) > 0
) rec

 UNION ALL

 SELECT NULL AS party, sum(dep) AS Balance 
 FROM (
 SELECT SUM(credit-debit) AS dep
 FROM `tabGL Entry`
 UNION ALL 
 SELECT SUM(credit-debit) AS nodep
 FROM `tabGL Entry`
) AS recb
 GROUP BY party WITH ROLLUP

Answer 1

使用此语法可以防止错误地附加GROUP BY：

( SELECT ... GROUP BY ... )
UNION ALL
( SELECT ... GROUP BY ... )

Versus

( SELECT ...  )
UNION ALL
( SELECT ...  )
GROUP BY ...

“小计”这个词来自哪里？我在查询中没有看到它。

我怀疑内心WITH ROLLUP被抛出。如果删除它们会发生什么？
