Data scientists, data analysts, and SAS programmers

  • Use SAS options to evaluate efficiency when accessing database data
  • Tune SAS programs for faster processing
  • Understand how relational database tables are accessed on the SAS Compute Server and in SAS Cloud Analytic Services (CAS)
  • Understand conditions that can prevent SQL pass-through for execution in the database
  • Modify SAS programs to maximize pass-through to the database and minimize execution time

Before attending this course, you should either have at least six months of experience writing SAS programs that include PROC SQL code or have completed the SAS(R) SQL 1: Essentials course and used PROC SQL in SAS for at least one month. The course builds on concepts presented in both the SAS(R) Programming I: Essentials and SAS(R) SQL 1: Essentials courses, and it is not recommended for beginning SAS software users. Specifically, you should be able to:

  • Access existing SAS data libraries using a LIBNAME statement.
  • Write and submit SAS programs to access and manipulate data using the DATA step and PROC SQL.
  • Read and interpret the SAS log.
  • Diagnose and correct syntax errors in SAS.
