从多列值计算百分比

Posted 2021-05-01

我想找到mysql查询来计算基于不同列上的值完成的工作百分比，以前我在Microsoft Excel中使用countif做到了这一点，但现在我想在mysql上创建相同的表。

这是我当前的表格

Parts Already Build : 
------------------------------------------------------------------
| id | Front   |  Rear   |  Left   | Right   |  Up     |  Down   |
__________________________________________________________________

| 01 | Done    |  Done   | Done    | Done    | Done    |  Done   |
------------------------------------------------------------------
| 02 | Done    |  Done   | Done    | Done    | No Need | No Need |
------------------------------------------------------------------
| 03 | Done    | Ongoing | Ongoing | Done    | Done    | Not Yet | 
------------------------------------------------------------------
| 04 | Not Yet | Not Yet | Not Yet | Not Yet | Not Yet | Not Yet |
------------------------------------------------------------------

预期结果

Parts Already Build : 
--------------------------------------------------------------------------------
| id | Front   |  Rear   |  Left   | Right   |  Up     |  Down   |   %   |  Status  |
________________________________________________________________________________

| 01 | Done    |  Done   | Done    | Done    | Done    |  Done   |  100  | Complete |
--------------------------------------------------------------------------------
| 02 | Done    |  Done   | Done    | Done    | No Need | No Need |  100  | Complete |
--------------------------------------------------------------------------------
| 03 | Done    | Ongoing | Ongoing | Done    | Done    | Not Yet |   50  | Ongoing  |
--------------------------------------------------------------------------------
| 04 | Not Yet | Not Yet | Not Yet | Not Yet | Not Yet | Not Yet |    0  | Not Yet  |
--------------------------------------------------------------------------------

注意：

1. 如果完成所有过程，或者在那6列中有6个“完成”值，则％列= 100
2. 如果值为“ No Need”，则将其计为“ Done”。
3. 如果不是所有过程都完成/没有过程完成，则表将仅计算有多少“完成”或“不需要”值，并将其转换为％列中的百分比（3/6进程为“完成” = 50 ％）
4. 如果％= 100％，则“状态”列=完成/如果= 0％=尚未/如果其他（1％-99％=正在进行）

当前查询：

SELECT
front,
rear,
left,
right,
up,
down,
_________________ AS %,
_________________ AS Status
FROM process

答案

SELECT `Front`, `Rear`, `Left`, `Right`, `Up`, `Down`, complete * 100 / 6 AS percent, CASE complete WHEN 6 THEN 'Complete' WHEN 0 THEN 'Not Yet' ELSE 'Ongoing' END AS status FROM (SELECT *, 0 + (Front = 'Done' OR Front = 'No Need') + (Rear = 'Done' OR Rear = 'No Need') + (`Left` = 'Done' OR `Left` = 'No Need') + (`Right` = 'Done' OR `Right` = 'No Need') + (Up = 'Done' OR Up = 'No Need') + (Down = 'Done' OR Down = 'No Need') AS complete FROM process) p
