Home -> Community -> Mailing Lists -> Oracle-L -> RE: alternative rows
For even numbered rows .....
select col_1, col_2
from (select col_1, col_2, rownum rnum
from my_table)
where mod(rnum, 2) = 0
For odd numbered rows ...
select col_1, col_2
from (select col_1, col_2, rownum rnum
from my_table)
where mod(rnum, 2) <> 0
A from clause select is useful because you can perform your ORDER BY etc in the from clause query and then use the rownum.
