SQL查询以获取列中的最大单词数

Question

I have a table with 3 columns. How do I query the column to get the words that appear the most in the column alone?

ID  Name   Age

#A  Gersh   9
#A  Marn    9  
#A  Drake   9 
#A  Hayford 2

My query should return the first 3 rows since 9 appears the most.

SQL

Select * from table group by age

Answer 1

use max()

select * from t where age= ( select max(age) from t)

or use rank() which sopported by most dbms

 select ID Name  Age from 
(
 select *,rank()over(order by age desc) rn from t
) a where rn=1

or you can use below if you need the most similar age occurred rows need

with cte as
(
select 'A' as n ,9 as age
union all
select 'B',9
union all
select 'C',9
union all
select 'D',2
)
 select n as name ,age from (
 select *,
 count(*) over(partition by age order by age) as cnt
 from cte
 ) t where cnt= ( select max(cnt) from
   (
   select *,
  count(*) over(partition by age order by age) as cnt
  from cte
   )a

      )
