MySQL從表中選擇列名等於

Question

我有一張簡單的桌子

amps | 120-240 | 120-208 | 277-480
__________________________________

10   |  $99.00  | $149.00 | $344.00

20   | $199.00 | $298.00 | $688

我想要類似這樣的查詢，但無法正常工作...

select * from `table` where amps like '10' and column_name like '120-208';

要么

select * from `table` where amps like '20' and column_name like '277-480';

請幫忙！ 也許我忽略了一種更簡單的設置方法？

謝謝！

像這樣？

SELECT `120-208` FROM table WHERE amps = '10'
