蜂巢中的分区排名

Question

我在 table A 中有数据，如下所示，有 3 列属性 id、结束日期和键，键字段必须为每个唯一组合填充一个唯一值属性 id和结束日期如下所示

key property id end date
1   7050    12/31/9999
2   7530    12/31/9999
2   7530    12/31/9999
2   7530    12/31/9999
2   7530    12/31/9999
3   7541    12/31/9999
3   7541    12/31/9999
3   7541    12/31/9999
4   7567    12/31/9999
4   7567    12/31/9999

我试过

select rank() over (partition by property_id,effective_end_date) as key,
       property_id,
       end_date 
 from table A

但它指定 1 作为所有记录的键。请帮助

Answer 1

使用下面的命令，使用命令：

select rank() over (ORDER by property_id,effective_end_date) as key,
   property_id,
   effective_end_date from table A

Answer 2

只需添加 Order by 即可，如下所示：

select rank() over (partition by property_id order by effective_end_date) as key,
       property_id,
       end_date 
 from table A
