我不知道如何自动完成此操作。我使用的实际表格太大了，不能像这个例子那样手动操作。任何指导或帮助将不胜感激，谢谢！

Answer 1

MySQL没有内置函数进行解包，因此您必须使用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'

结果将是你想要的SQL。
