对于以下查询输出，我有 2 个问题：


    COALESCE(Division,'Grand Total') Divi,
    COALESCE(Section,'DivTotal') Sec,
    COALESCE(m.Department,'SecTotal') Dept,
    COALESCE(Assortment,'DeptTotal') Assort,
    COALESCE(Promo,'') Prom,
    COALESCE(Range_Details,'') Range_,
    SUM(`WH STK`) WH_STK,
    SUM(`AL STK QTY`) AL_STK,
    SUM(`AL SAL QTY`) AL_SAL,
    SUM(`AL LYa`) LY_a,
    SUM(`AL LYb`) LY_b,
    SUM(`AL MIN`) AL_MIN,
    b.LYa_tot,
    b.LYb_tot,
    COALESCE(ROUND(((SELECT b.LYb_tot)/(SELECT b.LYa_tot))* COALESCE(SUM(`AL SAL QTY`),0),0),0) 'upcoming',
    COALESCE((ROUND(((SELECT b.LYb_tot)/(SELECT b.LYa_tot))*SUM(`AL SAL QTY`),0) +  SUM(`AL MIN`)) - SUM(`AL STK QTY`),0) 'Dispatch'

FROM
(.....I have removed rest of the query part to make it short....) m
GROUP BY
    m.Division,
    m.Section,
    m.Department,
    m.Assortment,
    m.Promo,
    m.Range_Details WITH ROLLUP HAVING
(Division IS NOT NULL AND Section IS NOT NULL AND Department IS NULL AND Assortment IS NULL AND Promo IS NULL AND Range_Details IS NULL )
OR (Division IS NOT NULL AND Section IS NOT NULL and Section NOT IN  ('OTHERS','W_ACCESSORIES','W_BOTTOMWEAR','W_INNERWEAR','W_UPPERWEAR') AND Department IS NOT NULL AND Assortment IS NULL AND Promo IS NULL AND Range_Details IS NULL )
OR (Division IS NOT NULL AND Section NOT IN  ('OTHERS','W_ACCESSORIES','W_BOTTOMWEAR','W_INNERWEAR','W_UPPERWEAR') AND Department IS NOT NULL and Department NOT IN ('GLOVE','RAINCOAT','SWIM SUIT','CORD TROUSERS','COTTON TROUSERS','FORMAL TROUSERS') AND Assortment IS NOT NULL AND Promo IS not NULL AND Range_Details IS not NULL )
OR (Division IS NULL AND Section IS NULL AND Department IS NULL AND Assortment IS NULL AND Promo IS NULL AND Range_Details IS NULL )

在此处输入图像描述 1.) 如何在最后一行仅保留“总计”并删除“DivTotal”、“SecTotal”、“DeptTotal”。

2.) 有没有更好的选择来使用“WITH ROLLUP”，这样我就可以只选择需要小计的列，而不是 GROUP BY 子句中所有列的小计？

注意：我已经在使用多个 UNION，所以如果可能，请给出没有联合的解决方案。无法嵌入图片，给您带来的不便深表歉意。

我认为 CTE 和摘要可能是一种更简单的方法：

with cte as (
      select m.Division, m.Section, m.Department, m.Assortment,  m.Promo, m.Range_Details,
             . . . 
      from . . .
      group by m.Division, m.Section, m.Department, m.Assortment,  m.Promo, m.Range_Details
     )
select *
from cte
union all
select 'Grand Total', null, null, null, null, null,
       sum(WH_STK), . . . 
from cte;

我以这种方式解决了这个问题，灵感来自 stackoverflow 本身的答案：

COALESCE(Division,'Grand Total') Divi,
(CASE WHEN Division IS NOT NULL THEN COALESCE(Section,'DivTotal') ELSE '' END) Sec,
(CASE WHEN Section IS NOT NULL THEN COALESCE(m.Department,'SecTotal') ELSE '' END) Dept,
(CASE WHEN m.Department IS NOT NULL THEN COALESCE(Assortment,' Total') ELSE '' END) Assort,
COALESCE(Promo,'') Prom,
(CASE WHEN Division IS NULL  THEN COALESCE(Range_Details,'Grand Total') ELSE COALESCE(Range_Details,'') END) Range_

感谢大家抽出时间。
