Ask the Expert Webinar Series

How Many Ways Can You Join SAS® Tables?

On-Demand • Cost: Complimentary

About the webinar

Why join data?

IT systems seldom store all data in one massive table, because it would result in extreme maintenance costs for the IT department. That’s why tables tend to be split up into smaller entities.

Enter the business need for joins, which are a means to access two or more tables to help answer business questions.

This presentation will describe various join algorithms and attempt to address comparisons between them.

You will learn about:

  • PROC SQL join with pass-through-implicit and explicit.
  • PROC FEDSQL join in SAS® Viya®.
  • Data step hash join.
  • Data step merge.
