How can I select 10th, 20th, 30th … row of the result of another select query

问题

I have a table with a column to, from and ID. I need to select only rows with every 10th ID which is from A to B.

回答1:

select * from 
(select * from table where from = 'A' and to ='B' order by ID)
where mod(rownum/10,1) = 0

It first takes only those from 'A' to 'B', then giving them rownums, and selecting only those in the 10th 20th ETC places..

回答2:

Or you can just use

select from, to, id 
from table1 
where id like'%0' and from ='A' and to = 'B'
