Sliding Window Syntax - response (1) by dnoeth

Hi John,
LEAD and LAG are just shortcuts for a basic OLAP function:

select id, yr, value,
  min(yr) 
  over (partition by id 
        order by yr
        rows between 1 following and 1 following) as next_yr, -- Oracle's LAG
  min(value) 
  over (partition by id 
        order by yr.
        rows between 1 following and 1 following) as next_value
from test1
qualify next_value is not null -- not the last row
order by id, yr
