Q:

Update the first 10000 rows, then the next 10000 and so on?

My table has close to 8 million rows. Is there a way to update first 10000 records and then the next 10000 records and so on.. till the 8 millionth record separately in Oracle?
I did check here for Select statement. But didn't find any solutions for an Update statement. Can someone please help? Hope this would help someone in need in the future.

A:

This is a simple solution if you know which records has already been updated. At least it will keep your transactions within a reasonable size.
DECLARE
    i number := 1;
BEGIN
    while i > 0 loop
      UPDATE < your table >
         SET col = <value>
         WHERE rownum < 100000
           AND <some statement that exclude already updated records>
      i := sql%rowcount;
      commit;
    end loop;
END;
