我最初尝试使用占用过多资源的单个查询来获取数据，因此我尝试组合查询以减少所花费的时间。第一个选择本身可以正常工作，但我想与第二个选择结合使用以减少花费的时间。

当前错误：#1241 - 操作数应包含 1 列

SELECT (SELECT sc.description AS description, 
           sc.maincode, 
           sc.controlcode, 
           sc.subcode, 
           ( ob.debitbalance - ob.creditbalance ) AS mainbalance 
    FROM   subcode AS sc 
           LEFT JOIN openingbalance AS ob 
                  ON ( sc.maincode = ob.maincode 
                       AND sc.controlcode = ob.controlcode 
                       AND sc.subcode = ob.subcode ) 
    GROUP  BY sc.maincode, 
              sc.controlcode, 
              sc.subcode 
    ORDER  BY sc.maincode, 
              sc.controlcode, 
              sc.subcode ASC) AS test, 
   (SELECT Sum(v.debit)                               AS totaldebit, 
           Sum(v.credit)                              AS totalcredit, 
           ( mainbalance + totaldebit - totalcredit ) AS openingbalance 
    FROM   subcode AS sc 
           LEFT JOIN voucher AS v 
                  ON ( sc.maincode = v.maincode 
                       AND sc.controlcode = v.controlcode 
                       AND sc.subcode = v.subcode ) 
    WHERE  Substring(v.voucherdate, 1, 7) < '07-2019' 
    GROUP  BY sc.maincode, 
              sc.controlcode, 
              sc.subcode 
    ORDER  BY sc.maincode, 
              sc.controlcode, 
              sc.subcode ASC) AS test2

表结构如下：

 Subcode Table
    +----------+-------------+---------+--------------+
    | Maincode | Controlcode | Subcode | Description  |
    +----------+-------------+---------+--------------+
    |       01 |          01 |     123 | Test Account |
    |       01 |          02 |     124 | Test Account |
    +----------+-------------+---------+--------------+

    Voucher Table
    +-------------+--------------+---------------+----------+-------------+---------+----------------+-------+--------+
    | Voucherdate | Vouchertype  | Vouchernumber | Maincode | Controlcode | Subcode |  Description   | Debit | Credit |
    +-------------+--------------+---------------+----------+-------------+---------+----------------+-------+--------+
    | 2019-07-13  | BV           |            01 |       01 |          01 |     123 | Entering Test  |   100 |      0 |
    | 2019-07-13  | BV           |            01 |       01 |          02 |     124 | Enterting Test |     0 |    100 |
    +-------------+--------------+---------------+----------+-------------+---------+----------------+-------+--------+

    OpeningBalance Table
    +----------+-------------+---------+--------------+---------------+
    | Maincode | Controlcode | Subcode | Debitbalance | Creditbalance |
    +----------+-------------+---------+--------------+---------------+
    |       01 |          01 |     123 |          100 |             0 |
    |       01 |          02 |     124 |          100 |             0 |
    +----------+-------------+---------+--------------+---------------+

期待接下来的结果

+--------------+----------+-------------+---------+-------------+------------+-------------+----------------+

简单的内部连接和一点数学应该可以解决问题

CREATE TABLE Subcode
    (`Maincode` int, `Controlcode` int, `Subcode` int, `Description` varchar(12))
;
    
INSERT INTO Subcode
    (`Maincode`, `Controlcode`, `Subcode`, `Description`)
VALUES
    (01, 01, 123, 'Test Account'),
    (01, 02, 124, 'Test Account')

| 2019-07 |

db<>在这里摆弄
