在 MySQL 报告中格式化漏斗报告的数据

Question

我正在寻找一种方法来为漏斗可视化创建 MySQL 报告。

所以我的输入是一个询问项目的查询。像项目 ID 123456

FROM projects WHERE ID = 123456

结果：

+---------+--------+-----+----------+------+
| Project | Income | Tax | Payments | Rent |
+---------+--------+-----+----------+------+
|  123456 |   2500 |  50 |      250 |  350 |
+---------+--------+-----+----------+------+

对于漏斗，我需要这样的报告：

+------+----------+-------+
| Step |   Name   | Value |
+------+----------+-------+
|    1 | Income   |  2500 |
|    2 | Tax      |    50 |
|    3 | Payments |   250 |
|    4 | Rent     |   350 |
+------+----------+-------+

是否有 SQL 方法将我的查询内容放入新列（步骤、名称、值）。

谢谢

Answer 1

您可以使用 union all 来反转您的 table:

select *
fom (
    select 1 step, 'Income' name, Income value from projects where project = 123456
    union all select 2, 'Tax', Tax from projects where project = 123456
    union all select 3, 'Payments', Payments from projects where project = 123456
    union all select 4, 'Rent', Rent from projects where project = 123456
)
order by step
