Hello all,
I have a question about perhaps using an array. Below is an example of a dataset I have that records sales from 5 different cities on 3 different dates.
Currently, information is stored in single columns. But what I want to do is to have each city be its own column with the sales under it. The code below does accomplish this:
However, I'm curious if this can be accomplished using an array so that 1 row represents only 1 date. I know I could use several methods like PROC SQL for fix this (since as it stands each date appears on 5 rows:
[CODE]proc sql;
create table test2 as
select distinct date, sum(A) as A, sum(B) as B, sum(C) as C, sum(D) as D, sum(E) as E
from test1
group by date;
run; quit;[CODE]
but would like to know if an easier method (like an array) can be used so that each city is its own variable. Thanks for any help!
