Select 来自 table 的试算表显示报表，只有一个金额栏和借方贷方栏

Question

我正在尝试使用来自 MySQL/MariaDB 的 SQL 查询来填充数据 table，以将其显示为 试算表 一个报告。

我的数据库引擎是 MariaDB 10.4.19

对于这个例子..我有 2 tables.

日记帐（包含交易）和

| id | date       | debit | credit| amount    |
|----|------------|-------|-------|-----------|
| 1  | 2021-09-01 | 8     | 2     | 5000.000  |
| 6  | 2021-09-22 | 22    | 17    | 4750.000  |
| 8  | 2021-09-05 | 8     | 3     | 1485.000  |
| 9  | 2021-08-10 | 8     | 6     | 108.000   |
| 10 | 2021-07-07 | 8     | 23    | 98756.000 |

分类帐帐户名称

| id | name                              | desc                              | status |
|----|-----------------------------------|-----------------------------------|--------|
| 1  | Assets                            | Current Assets                    | 1      |
| 2  | Stockholders equity               | Stockholders or Owners equity     | 1      |
| 3  | Liability                         | Liabilities related accounts      | 1      |
| 4  | Operating Revenues                | Operating Revenues                | 1      |
| 5  | Operating Expenses                | Operating Expenses                | 1      |
| 6  | Non-operating revenues and gains  | Non-operating revenues and gains  | 1      |
| 7  | Non-operating expenses and losses | Non-operating expenses and losses | 1      |
| 8  | Cash                              | For cash transaction              | 1      |

现在 从我的程序中，如果我 select 一个帐户（从分类账中填充）并提交它，它将发送它的 ID。使用该帐户 ID，我已经根据该帐户 ID 填充了所有交易。

例如：如果我选择现金账户，它会发送让我们说它会发送 8 作为 id。

现在

SQL 查询必须从日记帐中填充日期和金额，以及从分类帐中填充帐户名称 - 交易中 ID 为 8 的帐户名称。例如，如果它是 2，那么它将 return“股东权益”作为名称。
如果给定的 id 8 在借方中，金额应在 credit 列中，或者如果给定的 id 为 8，则金额应在 debit 列中id 8 已入账

如上几点，从程序中，如果帐户 ID 作为 8 传递（即“现金”）然后 DESIRED OUPUT SQL SELECT 查询结果应该如下所示...

| Date       | Account                          |    Debit |    Credit |
|------------|----------------------------------|---------:|----------:|

中的示例数据

你能告诉我如何使用连接 and/or 并集 SQL 查询来填充此结果 table 还是我应该使用其他方式...

请帮忙解答！

没有Total:

SELECT journal.date `Date`,
       ledger.name Account,
       CASE WHEN journal.dracc = 8 
            THEN 0.000
            ELSE amount
            END Debit,
       CASE WHEN journal.dracc = 8
            THEN amount
            ELSE 0.000
            END Credit
FROM journal
JOIN ledger ON (ledger.id, 8) IN ((dracc, cracc), (cracc, dracc));

与Total:

SELECT CASE WHEN NOT GROUPING(journal.id) 
            THEN MAX(journal.date) 
            END `Date`,
       CASE WHEN NOT GROUPING(journal.id) 
            THEN MAX(ledger.name) 
            ELSE 'Total'
            END Account,
       SUM(CASE WHEN journal.dracc = 8 
                THEN 0
                ELSE amount
                END) Debit,
       SUM(CASE WHEN journal.dracc = 8
                THEN amount
                ELSE 0
                END) Credit
FROM journal
JOIN ledger ON (ledger.id, 8) IN ((dracc, cracc), (cracc, dracc))
GROUP BY journal.id WITH ROLLUP;

与 Total 和 Balance:

WITH 
cte AS (
SELECT CASE WHEN NOT GROUPING(journal.id) 
            THEN MAX(journal.date) 
            END `Date`,
       CASE WHEN NOT GROUPING(journal.id) 
            THEN MAX(ledger.name) 
            ELSE 'Total'
            END Account,
       SUM(CASE WHEN journal.dracc = 8 
                THEN 0
                ELSE amount
                END) Debit,
       SUM(CASE WHEN journal.dracc = 8
                THEN amount
                ELSE 0
                END) Credit
FROM journal
JOIN ledger ON (ledger.id, 8) IN ((dracc, cracc), (cracc, dracc))
GROUP BY journal.id WITH ROLLUP
)
SELECT * 
FROM cte 
UNION ALL
SELECT NULL, 'Balance', NULL, Credit - Debit
FROM cte
WHERE `Date` IS NULL;

如果您的 MySQL 版本是 5.x 那么：

将WHEN NOT GROUPING(journal.id)替换为WHEN journal.id IS NOT NULL
将 CTE 转换为子查询
