Below is a simple example of pivot query in tsql and I am curious how this can be done efficiently in Qlik (I am using Sense but I don't think that is relevant). In the example below the column only contains 4 values but I would like a solution that could easily scale to values > 10. I searched the help and came up with a bunch of articles related to pivot tables. Are some solutions just better implemented in SQL or is that just the perception of a newbie?
createtable #t(v varchar(50), i int)
insertinto #t(v, i)values ('A,B,C,D',1)
,('E,F,G,H',2),('I,J,K,L', 3),('M,N,O', 4)
--Inorder to get into same row -pivoting the data
select*from #t t crossapply(select RowN=Row_Number()over (Orderby (SELECTNULL)),valuefromstring_split(t.v,',')) d) src
pivot(max(value)for src.RowN in(,,,)) p
