Abstract

PROC SQL is a powerful Base SAS® PROC combining the functionality of the DATA and PROC Steps into a single procedure. PROC SQL in some cases is a more efficient alternative to traditional SAS code. PROC SQL can be used to retrieve, update, and report on information from SAS data sets or other database products. This course will not discuss the use of PROC SQL as an interface tool to other database products, but rather it will concentrate on SQL syntax and how to access information from existing SAS data sets.
