Ordering/Ranking based on Character field

Question

Hi All,
I need to ordering/Rank a column based on varchar field.
Here is my input
Create table #InputTmp
CustomerNumber Varchar(10),
AccountNumber Varchar(10)
Insert into #InputTmp
Select '1234','123121'
Union All
Select '1234','4728272'
Union All
Select '3421','3234'
Union All
Select '434','232122'
Expected output:
here because customer number is same (1234) for first records i need assign 1 to 123121 and 2 to 4728272. if the customer number is not repeating then i have populate 1 in ordering field.
I have do it without using WITH clause.
Appreciate your inputs.
Regards,
Eshwar.

Answer 1

Out of curiosity, why without WITH clause?
Create table #InputTmp
CustomerNumber Varchar(10),
AccountNumber Varchar(10)
Insert into #InputTmp
Select '1234','123121'
Union All
Select '1234','4728272'
Union All
Select '3421','3234'
Union All
Select '434','232122'
select t.*
from
(SELECT *, RANK() OVER (PARTITION BY CustomerNumber ORDER BY AccountNumber) as Ordering
FROM #InputTmp t
) t
