我有一个类似于以下内容的数据库：
+------------+-----------+------------+
| student_id | subject | test score |
+------------+-----------+------------+
| 3 | math | 78 |
| 3 | physics | 66 |
| 3 | english | 98 |
| 2 | math | 76 |
| 2 | physics | 57 |
| 2 | geology | 87 |
| 2 | english | 99 |
| 1 | math | 86 |
| 1 | physics | 85 |
| 1 | astronomy | 89 |
| 1 | history | 77 |
+------------+-----------+------------+
我想将subject_ids分组。第二列中的标签将成为列，新行将成为分数。所以看起来应该是这样的：
+------------+------+---------+---------+---------+-----------+
| student_id | math | physics | english | geology | astronomy |
| 1 | 86 | 85 | | | 89 |
| 2 | 76 | 57 | 99 | 87 | |
| 3 | 78 | 66 | 98 | | |
+------------+------+---------+---------+---------+-----------+
