MySQL 行的小计与总计

2022-01-15 00:00:00 sql mariadb mysql

我需要创建一个 MariaDB SQL，它允许我对两列(借方和贷方列)求和以获得差异，并返回每种不同账户类型的小计.表格如下:

I need to create a MariaDB SQL that will allow me to sum two columns (Debit & Credit Columns) to get the difference, as well as return the subtotal of every different account type. The table is as follows:

 Account     | Debit  | Credit
 acc1        |   1    |   2 
 acc1        |   1    |   4
 acc2        |   3    |   2
 acc2        |   2    |   1
 acc2        |   2    |   1
 acc3        |   5    |   2
 acc3        |   5    |   1
 acc3        |   5    |   2

我想返回以下内容:

 Account     | Balance(debit-credit)
 acc1        |   -1    
 acc1        |   -3 
 -------------------------------
 Total acc1  |   -4 
 -------------------------------
 acc2        |   1
 acc2        |   1
 acc2        |   1
 -------------------------------
 Total acc2  |   3 
 -------------------------------
 acc3        |   3
 acc3        |   4
 acc3        |   3
 -------------------------------
 Total acc3  |   10 
 -------------------------------
 GrandTotal  |   9 
 -------------------------------

 Grandtotal is Totals of acc1 + acc2 + acc3

这是我到目前为止所尝试的，但我只得到总计而没有小计

This is what I have tried so far, how ever all I am only getting the grandtotal and no subtotals

SELECT * FROM (
 SELECT COALESCE(account,'TOTAL') AS Account, CASE
        WHEN account LIKE 'INC%' 
            THEN sum((gl.credit - gl.debit))
        ELSE sum((gl.debit - gl.credit))
    END AS Balance
 FROM `tabGL Entry` gl
 WHERE (NOT (account LIKE 'CASS%')
     AND NOT (account LIKE 'CLIA%')
     AND NOT (account LIKE 'FASS%'))
 GROUP BY account WITH ROLLUP
) AS gl
 ORDER BY CASE
     WHEN account LIKE 'INC%' THEN 1
     WHEN account LIKE 'DCOI%' THEN 2
     WHEN account LIKE 'DMC%' THEN 3
     WHEN account LIKE 'INFC%' THEN 4
     WHEN account LIKE 'IDEX%' THEN 5
     ELSE 6
 END

推荐答案

你可以试试UNION，比如:

SELECT * 
  FROM (SELECT COALESCE('TOTAL ', account) AS Account
               , SUM(CASE WHEN account LIKE 'INC%' 
                          THEN (gl.credit - gl.debit)
                          ELSE (gl.debit - gl.credit)
                      END) AS Balance
          FROM `tabGL Entry` gl
         WHERE (NOT (account LIKE 'CASS%')
           AND NOT (account LIKE 'CLIA%')
           AND NOT (account LIKE 'FASS%'))
         GROUP BY account WITH ROLLUP
  -- UNION SELECT account
  --              , CASE WHEN account LIKE 'INC%' 
  --                     THEN (gl.credit - gl.debit)
  --                     ELSE (gl.debit - gl.credit)
  --                 END AS Balance
  --         FROM `tabGL Entry` gl
  --        WHERE (NOT (account LIKE 'CASS%')
  --          AND NOT (account LIKE 'CLIA%')
  --          AND NOT (account LIKE 'FASS%'))
) AS gl
 ORDER BY CASE
 WHEN account LIKE 'INC%' THEN 1
 WHEN account LIKE 'DCOI%' THEN 2
 WHEN account LIKE 'DMC%' THEN 3
 WHEN account LIKE 'INFC%' THEN 4
 WHEN account LIKE 'IDEX%' THEN 5
 ELSE 6
END

我认为这应该做你想做的事

I think this should do what you want

注释掉的部分是单行，上半部分是小计

The commented-out part is for the single rows, the upper part for subtotals

现在在此处的最后一条评论之后，为您提供小计和总计的查询

Now after the last comment here the query that gives you the subtotals and the grandtotal

按 COALESCE 分组似乎是个问题，所以现在由 LEFT(account,3) 完成，ORDER 语句必须修改为 3 个字符

grouping by COALESCE seemed to be the Problem so now it's done by LEFT(account,3) and the ORDER Statement had to be modified to 3 Chars

SELECT * 
  FROM (SELECT LEFT(account,3) AS Account
           , SUM(CASE WHEN account LIKE 'INC%' 
                      THEN (credit - debit)
                      ELSE (debit - credit)
                  END) AS Balance
          FROM acc
         GROUP BY LEFT(account,3) WITH ROLLUP
) AS ac
 ORDER BY CASE
 WHEN account LIKE 'INC%' THEN 1
 WHEN account LIKE 'DCO%' THEN 2
 WHEN account LIKE 'DMC%' THEN 3
 WHEN account LIKE 'INF%' THEN 4
 WHEN account LIKE 'IDE%' THEN 5
 ELSE 6
END
