列總計行和調換（SQL服務器）

Question

，我有以下數據集：

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

我怎樣才能通過每一列的總一行首先：

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

，然後轉置它看起來像這樣：

Can 5 
Fra 20 
Scl 1 

Answer 1

此查詢應該會對您有所幫助。這將避免不必要的中間步驟。您可以直接得到最終結果下面的查詢

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

如果你想獲得總每一列的，那麼你可以使用：

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
