如何在mysql中使用折扣计算产品的价格？

我有一个products表，存储原价和折扣百分比：

mysql> select * from products;
+---------------+--------+-----------+--------+
| concept       | price  | discount  | currency |
+---------------+--------+-----------+--------+
| yyy           |      1 |      0.00 | usd    |
| xxx           |     10 |     50.00 | usd    |
+---------------+--------+-----------+--------+

如何使用“价格和折扣”列计算SELECT stament中每个项目的总价，以便获得以下信息

mysql> select ???????
+---------------+--------+--------+
| concepto      | total  | currency |
+---------------+--------+--------+
| yyy           |     1  | usd    |
| xxx           |     5  | usd    |
+---------------+--------+--------+

这是简单的算术：

select 
    concept,
    price * (1 - discount / 100) total,
    currency
from products
