This comprehensive course teaches professionals how to leverage Structured Query Language (SQL) for processing and managing SAS data efficiently. You will gain hands-on expertise in querying, subsetting, and analyzing data while mastering advanced database operations.
Core Learning Objectives:
- Query and subset data using SQL syntax within SAS environments
- Summarize and present data through sophisticated reporting techniques
- Combine multiple tables using various join methods and set operators
- Create and modify tables and views for data organization
- Generate data-driven macro variables directly from query results
- Access external DBMS data seamlessly with SAS/ACCESS technology
Ideal Audience:
This course is designed for SAS programmers, database administrators, and business analysts who need to work with SQL within the SAS environment. It is particularly valuable for those transitioning from SQL-only workflows to integrated SAS programming.
