Hi,

Lets says I have the following table :

CUSTOMER_IDIDCOMMENTS
1234530feadsaf
1234532argaefr
1234533dfasdsa
1111146fdasdfasd
1111148fadsfdas
3456778afsdffsd

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;
