proc sql

[Prateek1]

hi,

 what should be the code for this  question ?

In the SMB usage data, create another column  to identify churners by using product_ID as key variable (check if the key variable is uniqueID  in this case ).the list of churners is given in the 'Churners and labels' along with churn month .use LEFT JOIN OR Right Join .

First: please use some descriptive subjects than "proc sql". It would help to distinguish between your inquiries.
Second: what are you up to? Since you have severe more or less basic SQL questions I sugest that you take some formal training first, and then return to the forum more specific coding problems, or at least show the code you tried so far.
