Question

I have a table called table_one. (7 Mil) rows

I want to insert 0 – 1 Mil on a new table (table_two) and then insert 1Mil one – 2mil to the same table.

SET ROWCOUNT 1000000

How can this be achieved? Is there a way to specify range of rows to be inserted?

Answer 1

You can use row_number:

;with cte as (
   select 
      *, 
      row_number() over(order by some_field ) as rn
   from table_one
)
insert into table_two ( fields )
  select fields from cte
   where rn < 1000000
