mysql> SELECT billing_amount, billing_currency_code, source_amount, source_currency FROM visa_record;
+----------------+-----------------------+---------------+-----------------+
| billing_amount | billing_currency_code | source_amount | source_currency |
+----------------+-----------------------+---------------+-----------------+
| 31651 | EUR | 48563 | USD |
+----------------+-----------------------+---------------+-----------------+
但我想是這樣的:
Visa Record Information
+----------------+-----------------------+---------------+-----------------+
| billing_amount | billing_currency_code | source_amount | source_currency |
+----------------+-----------------------+---------------+-----------------+
| 31651 | EUR | 48563 | USD |
+----------------+-----------------------+---------------+-----------------+
不,那不是mysql的意思,這應該在應用程序級別上完成。 –
