Not sure how we are supposed to tell from that. Are there observations in the dataset? Its telling you there was nothing to update. The syntax works fine to update all rows in the dataset,
data want; a="hello"; run; proc sql; update want set a="Goodbye"; quit;
So either that dataset has no observations or you don't have permission to change it.

Due to the fact you don't want to use communication I will guess that your post means that there is no observations, hence update has nothing to update. If I was you I would start by learning Base SAS:
These will guide you on how to do all the various things in Base SAS - this is the language you are using so its good to have a thorough knowledge of it before adding additional sub components like SQL. Several of the early videos will show multiple ways of getting data into SAS datasets to work on.
