Oracle sql使用Soundex查找类似的字符串

Question

我有表HumanNames

输入是

|HumanName      |
|-------------  |
|Kamil          |
|Azer           |
|John           |
|Elmir          |
|Kamal          |
|Elmar          |
|Orxan          |
|Elnar          |

我需要写查询,它会给出与其他名称相同的结果名称.期望的输出是

|NamesWhichLikes  |
|-------------    |
|Kamil,Kamal      |
|Elmir,Elmar,Elnar|
|                 |

Answer 1

试试这个使用listagg和group by对soundex命名的:

with your_table (HumanName) as (
select 'Kamil' from dual union all 
select 'Azer'  from dual union all 
select 'John'  from dual union all 
select 'Elmir' from dual union all 
select 'Kamal' from dual union all 
select 'Elmar' from dual union all 
select 'Orxan' from dual union all 
select 'Elnar' from dual
)
------ Test data setup ends here ------


select
    listagg(humanname,',') within group (order by humanname) nameswhichlikes
from your_table
group by soundex(humanname)
having count(*) > 1;

生产:

+---------------------------+
| NAMESWHICHLIKES           |
+---------------------------+
| Elmar,Elmir,Elnar         |
+---------------------------+
| Kamal,Kamil               |
+---------------------------+

如果名称重复:

select
    listagg(humanname,',') within group (order by humanname) nameswhichlikes
from (select distinct humanname from your_table)
group by soundex(humanname)
having count(*) > 1;
