Split and mark the records

Question

Hi all,
I have the below scenario where i need to mark every 4 records with a number. The count of ids can vary for example i am taking 10 id's. Can any one suggest a sql statement to achieve this. Thanks for looking into it.
id         mark_id
1            1
2            1
3            1
4            1
5            2
6            2
7            2
8            2
9            3
10           3

Answer 1

Hi,
Here's one way:
SELECT       id
,       CEIL ( ROW_NUMBER () OVER (ORDER BY id)
            / 4
            )     AS mark_id
FROM       table_x
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.
