我不知道如何來自動完成這個任務。我使用的實際表格太大，無法像本例那樣手動進行。任何指導或幫助將不勝感激，謝謝！

Answer 1

MySQL沒有內置功能unpivoting，所以你將不得不使用UNION ALL：

SELECT 'A' AS Country, Date, A As 'Amount' 
FROM yourTable 
UNION ALL 
SELECT 'B' AS Country, Date, B As 'Amount' 
FROM yourTable 
UNION ALL 
SELECT 'C' AS Country, Date, C As 'Amount' 
FROM yourTable 
UNION ALL 
SELECT 'D' AS Country, Date, D As 'Amount' 
FROM yourTable 
UNION ALL 
SELECT 'E' AS Country, Date, E As 'Amount' 
FROM yourTable 

Answer 2

SELECT 'SELECT ''' + [COLUMN_NAME] +''' as Country, Date, Amount 
FROM yourTable 
WHERE Country =''' + [COLUMN_NAME] +''' UNION' 
FROM [INFORMATION_SCHEMA].[COLUMNS] 
WHERE [TABLE_NAME] ='yourTable' 

而且比結果會是你想要的SQL。
