PROC SQL Continued – Basic Text Analytics Using Song Titles

hi,

what should be the code ?

In the SMB usage data create another column to identify churners by using Product_ID as key variable (check if the key variable is unique ID in this case ).The list of churners is given in the 'Churners and labels' along with churn month .Use left join or Right Join?

Hi Prateek1,

Looking at your data on the "Churners" sheet, I see that for each unique PRODUCT_ID there is only one unique value of churn_month, is that correct? To shorten your list and get a list of unique PRODUCT_IDs with their associated churn_month values,

proc sql;

     select distinct(PRODUCT_ID), churn_month from Churners;

quit;
