如果我有一个类似上面的示例表的表。是否可以运行一个查询，该查询将导致像mysql中的以下示例一样的表？

+---------+---------+----------+
| number  |    A    |     B    |
+---------+---------+----------+
|    1    |   7.00  |   3.00   | 
|    2    |   1.00  |   2.00   | 
|    3    |   6.00  |   9.00   |

Answer 1

select number,
       min(case when `type` = 'A' then price end) as A,
       min(case when `type` = 'B' then price end) as B
from your_table
group by number
