同一张表的不同列的计数总和 [英] sum of counts of different columns of same table

问题描述

在名为table的表下面给出

Given below table called table

+---+---+
| x | y |
+---+---+
| 1 | 2 |
| 1 | 5 |
| 5 | 2 |
| 5 | 1 |
+---+---+

我想对以下结果进行sql查询

I want to have sql query for the following results

+----+-------------+
| id | count_total |
+----+-------------+
|  1 |           3 |
|  2 |           2 |
|  5 |           3 |
+----+-------------+

注意: 我能够分别计算每个ID的行数，但无法获得相同ID的总和. 所以我想在单个查询中合并或获取以下查询的总和.

Note: I was able to count separately the rows per id but I could not get the sum for the same id. so I want to combine or get sum of below queries in a single query.

SELECT x, count(*) as total_x FROM table GROUP BY x
SELECT y, count(*) as total_y FROM table GROUP BY y

推荐答案

尝试:

SELECT
A.ID, SUM(A.COUNTS) AS COUNT_TOTAL
FROM
(
SELECT X AS ID, COUNT(*) AS COUNTS FROM TABLE1 GROUP BY X
UNION ALL
SELECT Y AS ID, COUNT(*) AS COUNTS FROM TABLE1 GROUP BY Y
) A
GROUP BY A.ID
ORDER BY A.ID;
