Question

我找不到查询，但我尝试了波纹管查询，但是它不起作用

SELECT DISTINCT(Salary) FROM table ORDER BY Salary DESC LIMIT n,1

A006 KAP10 900000
A007 APP10 700000

union all select 30 from sysibm.sysdummy1
union all select 30 from sysibm.sysdummy1
union all select 40 from sysibm.sysdummy1
)
select distinct salary
from (
select salary, dense_rank() over (order by salary desc) r_
from mytab
