Question

Hi I’ve got some SQL …

SELECT  
    AdviceNo,
    Registration
FROM tblSalesDetail

that produces something like …

ADV00001, ABC123
ADV00001, CDE564
ADV00002, FGE432
ADV00003, HUY789
ADV00003, MJS532
ADV00003, JFY428

Can anyone tell me how I’d adjust it to see the following please?

ADV00001, ABC123, 1
ADV00001, CDE564, 2
ADV00002, FGE432, 1
ADV00003, HUY789, 1
ADV00003, MJS532, 2
ADV00003, JFY428, 3

How’s about Oracle Analytical Functions?

This is a classical example in which RANK is useful 😉

SELECT AdviceNo,
       Registration,
       RANK () OVER (PARTITION BY AdviceNo ORDER BY Registration ASC) MY_RANK
  FROM tblSalesDetail;
