在mySQL中的反向計數

Question

id one two thr fou five 
1 37 84 1 68 10 
2 72 50 87 41 67 
3 66 30 89 57 48 
4 29 27 35 75 36 
5 2 72 9 1 55 
6 33 89 17 40 64 
7 70 90 63 26 54 
8 36 19 51 43 61 
9 10 61 20 44 84 
10 2 41 43 65 87 

我需要反轉計數上表中的每個數字。

例子：

61=>1 because if you count from the bottom to the first 61 there's 1 row 
26=>3 because if you count from the bottom to the first 26 there are 3 rows 
9=>5 because if you count from the bottom to the first 9 there are 5 rows 
and so on... 

查詢應輸出類似於所有數字如下表：

Number Rows count 
61 1 
26 3 
9 5 

這裏的問題是：如何扭轉計數的MySQL？有特殊功能嗎？ 謝謝

Answer 1

如果您通過id命令應該這樣做，您可以使用（Count（*） - id）獲得您想要的計數。

如果沒有，我相信你可以使用@curRow標籤，如果id不正確。看看這些問題：

MySQL get row position in ORDER BY

With MySQL, how can I generate a column containing the record index in a table?

Answer 2

select COUNT(*) from TestTbl 
where id > (select max(id) from TestTbl 
where one='9' or two ='9' or three='9' or four='9' or five='9') 

select COUNT(*) from TestTbl 
where id > (select max(id) from TestTbl 
where one='26' or two ='26' or three='26' or four='26' or five='26') 

select COUNT(*) from TestTbl 
where id > (select max(id) from TestTbl 
where one='61' or two ='61' or three='61' or four='61' or five='61') 

Answer 3

這裏是我想出了。它很醜。

select num, t1.max - t2.id as reverse_count from 
(select max(id) as max from testtable) as t1, 
(select id, row1 as num from testtable union all select id, 
row2 as num from testtable union all select id, 
row3 as num from testtable union all select id, 
row4 as num from testtable) as t2; 

編輯使用正確的命名方案

select num as Number, t1.max - t2.id as RowsCount from 
(select max(id) as max from testtable) as t1, 
(select id, one as num from testtable union all select id, 
two as num from testtable union all select id, 
thr as num from testtable union all select id, 
fou as num from testtable union all select id, 
five as num from testtable) as t2; 

Answer 4

這將是清潔如果MySQL有一個UNPIVOT功能：

SELECT x.num, co.co - count(x.id) FROM 
    (SELECT count(id) as co FROM tab) as co, 
    (SELECT t.num, max(t.id) as 'id' FROM 
     (SELECT id, one as 'num' FROM tab 
     UNION 
     SELECT id, two as 'num' FROM tab 
     UNION 
     SELECT id, thr as 'num' FROM tab 
     UNION 
     SELECT id, fou as 'num' FROM tab 
     UNION 
     SELECT id, fiv as 'num' FROM tab) as t 
    GROUP BY t.num) as x 
    INNER JOIN 
    (SELECT id FROM tab) as y on x.id >= y.id 
GROUP BY x.num, co.co
