我的表格看起来像这样：
ProductList
+------+----------------+--------------+----------+--------+-------+
| id | product_number | product_type | location | status | price |
+------+----------------+--------------+----------+--------+-------+
| 1 | A-01 | A001 | Nevada | READY | 5000 |
| 2 | B-02 | A002 | Texas | STORED | 6000 |
| 3 | A-01 | A002 | Utah | READY | 6000 |
| 4 | A-02 | B003 | Utah | READY | 8000 |
| 5 | B-01 | A001 | Nevada | STORED | 5000 |
+------+----------------+--------------+----------+--------+-------+
id是主键。
Supervisor
+------+-------+--------------+----------+-----------+--------+
| id | month | product_type | location | unit_sold | income |
+------+-------+--------------+----------+-----------+--------+
| 1 | 1 | A001 | Nevada | 5 | 25000 |
| 2 | 3 | A002 | Texas | 6 | 36000 |
| 3 | 1 | A002 | Utah | NULL | NULL |
| 4 | 4 | B003 | Utah | 4 | 32000 |
| 5 | 2 | A001 | Nevada | 6 | 30000 |
+------+-------+--------------+----------+-----------+--------+
我被问到结果应该像这张表（这实际上是我的估计）：
SalesTarget table
Location : Nevada
+------+----------------+--------+--------+---------------+---------------+
| | STATUS | TOTAL | 1st MONTH | 2nd MONTH |
| TYPE | READY | STORED | UNIT | PRICE | UNIT | INCOME | UNIT | INCOME |
+------+-------+--------+--------+--------+------+--------+------+--------+
| A001 | 6 | 8 | 14 | 70000 | 5 | 25000 | 6 | 30000 |
| A002 | 7 | 4 | 11 | 66000 | 3 | 39000 | 0 | 0 |
| B001 | 3 | 6 | 19 | 95000 | 0 | 0 | 0 | 0 |
| B002 | 5 | 5 | 10 | 100000 | 4 | 40000 | 6 | 60000 |
+------+-------+--------+--------+--------+------+--------+------+--------+
该表仅显示来自特定location的数据。 STATUS READY是具有 READY 状态的相同类型和位置的单位累积，因此STATUS STORED也是如此。 TOTAL是Location中相同类型的总单位/价格。
SalesTarget表中的单位和收入可以为NULL，并且将由用户输入，但它们按Supervisor.month分类（并且也是第12个月）。
我通过product_type加入了表（ProductList和Supervisor）。
我尝试使用这样的预处理语句查询命令，但它没有给出我想要的确切结果。
SELECT
pl.product_type AS TYPE,
SUM(IF(pl.status = ? , 1, 0)) AS READY,
SUM(IF(pl.status = ? , 1, 0)) AS STORED,
SUM((IF((pl.status = ? OR pl.status = ? ), 1, 0))) AS UNIT_TOTAL,
SUM((IF((pl.status = ? OR pl.status = ? ), pl.price, 0))) AS PRICE_TOTAL,
IF(sv.month=1, sv.unit_sold, 0) AS UNIT1,
IF(sv.month=1, sv.income, 0) AS INCOME1,
IF(sv.month=2, sv.unit_sold, 0) AS UNIT2,
IF(sv.month=2, sv.income, 0) AS INCOME2
FROM ProductList pl
LEFT OUTER JOIN Supervisor sv ON pl.product_type = sv.product_type
WHERE pl.location = ?
GROUP BY pl.product_type
ORDER BY TYPE DESC
我该怎么做？
