MySQL中ROLLUP的替代方法_MySQL

bitsCN.com 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 |
+----------+-------------+
