Hi,
Lets says I have the following table :
CUSTOMER_ID | ID | COMMENTS |
---|---|---|
12345 | 30 | feadsaf |
12345 | 32 | argaefr |
12345 | 33 | dfasdsa |
11111 | 46 | fdasdfasd |
11111 | 48 | fadsfdas |
34567 | 78 | afsdffsd |
What is the proper sas or sql query to create a table where I would have the customer_id and the comments only for the latest ID?
Thank you for your help and time.
Use a data step and last.
proc sort data=have; by customer_id id;
data want;
set have;
by customer_id;
if last.customer_id;
run;
OR two proc sorts;
proc sort data=have; by customer_id descending id; run;
proc sort data=have out=want nodupkey; by customer_id; run;

Got it to work.
