MySQL中ROLLUP的替代方法

今天从MySQL中提取数据，使用ROLLUP统计后，想在数据左边列中加入项目名称，使用SQL
Sql代码 
SELECT (CASE WHEN ISNULL(PLAYERNO) THEN PLAYERNO=TOTAL ELSE PLAYERNO END) AS PLAYERNO,SUM(AMOUNT) FROM penalties 
GROUP BY PLAYERNO WITH ROLLUP 
 结果是：
这样
+----------+-------------+
| PLAYERNO | SUM(AMOUNT) |
+----------+-------------+
|        6   |      100.00 |
|        8   |        25.00 |
|       27  |      175.00 |
|       44  |      130.00 |
|      104 |        50.00 |
|     NULL|      480.00 |
+----------+-------------+
6 rows in set, 1 warning (0.00 sec)
 
显示为空值，修改如下：
Sql代码 
SELECT PLAYERNO,SUM(AMOUNT) FROM penalties 
GROUP BY PLAYERNO 
UNION 
SELECT TOTAL,SUM(AMOUNT) 
FROM penalties 
 
显示结果：
+----------+-------------+
| PLAYERNO | SUM(AMOUNT) |
+----------+-------------+
| 6          |      100.00 |
| 8          |        25.00 |
| 27        |      175.00 |
| 44        |      130.00 |
| 104      |        50.00 |
| TOTAL  |      480.00 |
+----------+-------------+
6 rows in set (0.00 sec)
