Kinek ajánljuk


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 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 Programming 1: Essentials and SAS 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.

A tanfolyam SAS/ACCESS, Base SAS szoftver használatára épül.

This course uses Base SAS, SAS/ACCESS to Oracle, SAS Viya Cloud Analytic Services, and SAS Viya data connector software. It is appropriate for students who are using either SAS 9 or SAS Viya.
