行和行转置总数（SQL服务器）

Question

我有以下数据集：

Account|Can|Fra|scl|
1012    0    10   1
1011    5    10   0

如何首先获得连续每列的总数：

Account|Can|Fra|scl|
1012    0    10   1
1011    5    10   0
Total   5    20   1

然后转置它，看起来像这样：

Can 5
Fra 20
Scl 1

Answer 1

此查询可以帮助您。它将避免不必要的中间步骤。您可以使用以下查询直接获得最终结果

SELECT 'CAN' AS COUNTRY, SUM(CAN) AS COUNTVAL FROM MY_TABLE
UNION ALL
SELECT 'FRA' AS COUNTRY, SUM(FRA) AS COUNTVAL FROM MY_TABLE
UNION ALL
SELECT 'SCL' AS COUNTRY, SUM(SCL) AS COUNTVAL FROM MY_TABLE

如果您想获得每列的总数，那么您可以使用：

SELECT ACCOUNT, CAN, FRA,SCL FROM MY_TABLE
UNION ALL
SELECT 'TOTAL' AS ACCOUNT, SUM(CAN) AS CAN, SUM(FRA) AS FRA, SUM(SCL) AS SCL 
       FROM MY_TABLE
