Adding Incremental SQL to relevant IDs

Question

See more:

Hi there, what I am trying to do is pull out data, and group by a relevant ID then add incremental dependant on the IDs, so for each of those ID rows I want to add 1 2 3 4 5 6 etc.

so for example

ID     -           Value
333     -          1
333      -         2
333       -        3
333        -       4
333         -      5

456          -     1
456           -    2
456            -   3

I have tried several scenarios but all failed... any ideas?

SQL

SELECT table1.choice1a, Sum(table1.choice1b) AS SumOchoice1b
FROM table1
GROUP BY table1.choice1a
HAVING (((table1.choice1a) Is Not Null));

Solution 2

Use ROW_NUMBER() if you are using SQL 2005 or more..
Example:

SQL

SELECT table1.choice1a, table1.choice1b AS SumOchoice1b, row_number() over(partition by table1.choice1b order by table1.choice1b) as myrank 
FROM table1

check the following link for an example:

Depending on the version of your SQL Server, you can do the following:

SQL 2000
For SQL 2000, I believe there should be a unique ID for you to be able to do it. Not sure if there are solutions that does not require you to have a unique ID.

SQL

SELECT 
tbl2.PKID, -- this is your unique ID
tbl2.ID, 
(select count(1) from table1 where PKID <= tbl2.PKID and ID = tbl2.ID) AS RowNumber
from table1 tbl2
order by ID, RowNumber

SQL 2005

SQL

SELECT
tbl1.ID,
ROW_NUMBER() OVER(PARTITION BY ID ORDER BY ID) AS RowNumber
from table1 tbl1
