concatenate value of multiple rows into one Single row - response (3) by mensssanvi

 
I am trying to create a group of ranking as shown in below table. I've used the row () over partition function it is just doing a row numbering. In fact, I want the min row number in column "clust_n" to be allocated when rows in column wh_no match. (e.g. when 7923 come 3 times I would like clust_n to show 4,4,4 not 4,5,6
