SAS Query

[Toffeeman]

My original code:

%let customer = ('ABC','CDE');

data cust;

set cust;

if customer in &customer then discount = discount*0.1;

run;

Question:

I have put the customer info in dataset to avoid input manually into the program

dataset (dataset name: CUST)

customer

ABC

CDE

May i know how to read the customer name from the dataset? and work get the similar result as my original code.

Anyone can help? Please advise.  Thanks.

Assuming you put your list of special customers in dataset specialCust, you can adjust their discount in dataset CUST with:

proc sql;
update cust
set discount = discount*0.1
where customer in (select customer from specialCust);
quit;
