Transpose or Pivot without using PIVOT or UNPIVOT SQL Editor in Metabase

问题

我正在尝试转置我的表格列和行,但是转置功能还没有包含在Metabase的功能中。现在我正在尝试在其SQL编辑器中手动执行,但是由于某种原因,PIVOT不是已知的功能。

我有一个包含列Interval、Count和Percentage的表格

Interval Count Percentage
0 - 60 50 .78
61 - 120 10 .16
120 > 4 .06

我想将它转换成这样

0 - 60 61 - 120 120 >
50 10 4
.78 .16 .06

我尝试过以下作为一种尝试。

  1. select
  2. max(case when Interval = '0 - 60' then Count end) as "0 - 60"
  3. max(case when Interval = '0 - 60' then Count end) as "0 - 60"
  4. max(case when Interval = '0 - 60' then Count end) as "0 - 60"
  5. from t
  6. union
  7. select
  8. max(case when Interval = '0 - 60' then Percentage end) as "0 - 60"
  9. max(case when Interval = '0 - 60' then Percentage end) as "0 - 60"
  10. max(case when Interval = '0 - 60' then Percentage end) as "0 - 60"
  11. from t

但是生成的查询结果总是将百分比放在顶部,即使我更改select的顺序也是如此。

0 - 60 61 - 120 120 >
.78 .16 .06
50 10 4

I am trying to transpose my table columns and rows however transpose is not yet included in the functionality of Metabase. Now I am trying to manually do it in its SQL Editor however PIVOT is not a known functionality for some reason.

I have a table with columns Interval, Count, Percentage

Interval Count Percentage
0 - 60 50 .78
61 - 120 10 .16
120 > 4 .06

And I am trying to convert it like this

0 - 60 61 - 120 120 >
50 10 4
.78 .16 .06

What I have tried is using as a trial.

  1. select
  2. max(case when Interval = '0 - 60' then Count end) as "0 - 60"
  3. max(case when Interval = '0 - 60' then Count end) as "0 - 60"
  4. max(case when Interval = '0 - 60' then Count end) as "0 - 60"
  5. from t
  6. union
  7. select
  8. max(case when Interval = '0 - 60' then Percentage end) as "0 - 60"
  9. max(case when Interval = '0 - 60' then Percentage end) as "0 - 60"
  10. max(case when Interval = '0 - 60' then Percentage end) as "0 - 60"
  11. from t

But the resulting query will always put percentage at the top first even if I change the order of select

0 - 60 61 - 120 120 >
.78 .16 .06
50 10 4

得分: 0

使用以下代码:

  1. SELECT *
  2. FROM
  3. (
  4. SELECT
  5. max(CASE WHEN Interval = '0 - 60' THEN Percentage END) AS '0 - 60',
  6. max(CASE WHEN Interval = '61 - 120' THEN Percentage END) AS '61 - 120',
  7. max(CASE WHEN Interval = '120 >' THEN Percentage END) AS '120 >',
  8. 2 as sort_order
  9. FROM #TESTS
  10. UNION
  11. SELECT
  12. max(CASE WHEN Interval = '0 - 60' THEN Count END) AS '0 - 60',
  13. max(CASE WHEN Interval = '61 - 120' THEN Count END) AS '61 - 120',
  14. max(CASE WHEN Interval = '120 >' THEN Count END) AS '120 >',
  15. 1 as sort_order
  16. FROM #TESTS
  17. ) t
  18. ORDER BY sort_order;

祝好运!

英文:

Use following Code

  1. SELECT *
  2. FROM

  4. SELECT
  5. max(CASE WHEN Interval = '0 - 60' THEN Percentage END) AS ' 0 - 60',
  6. max(CASE WHEN Interval = '61 - 120' THEN Percentage END) AS ' 61 - 120',
  7. max(CASE WHEN Interval = '120 >' THEN Percentage END) AS ' 120 >',
  8. 2 as sort_order
  9. FROM #TESTS
  10. UNION
  11. SELECT
  12. max(CASE WHEN Interval = '0 - 60' THEN Count END) AS ' 0 - 60',
  13. max(CASE WHEN Interval = '61 - 120' THEN Count END) AS ' 61 - 120',
  14. max(CASE WHEN Interval = '120 >' THEN Count END) AS ' 120 >',
  15. 1 as sort_order
  16. FROM #TESTS
  17. ) t
  18. ORDER BY sort_order ;

Good Luck;
