SAS Tip of the Month
May 2013
(for SAS and WPS)

Sometimes we want to add the observation number to a dataset. In the datastep we can easily do

   data dataset;
      set dataset;

However, if you are using SQL, this is not so easy. There is an undocumented function called the MONOTONIC function that will help, as the following code shows:

   proc sql;
      create table dataset as
         select monotonic() as N, *
         from dataset;

Have a safe and happy May.
