Advanced SAS : Test Content

Accessing Data Using SQL

  • Generate detail reports by working with a single table or joining tables using PROC SQL and the appropriate options
  • Generate summary reports by working with a single table or joining tables using PROC SQL and the appropriate options
  • Construct sub queries within a PROC SQL step
  • Compare solving a problem using the SQL procedure versus using traditional SAS programming techniques
  • Access Dictionary Tables using the SQL procedure
  • Demonstrate advanced PROC SQL skills by creating and updating tables, updating data values, working with indexes using the macro interface/creating macro variables with SQL, defining integrity constraints, SQL views and SET operators

Macro Processing

  • Creating and using user-defined and automatic macro variables within the SAS Macro Language
  • Automate programs by defining and calling macros using the SAS Macro Language
  • Understand the use of macro functions
  • Recognize various system options that are available for macro debugging and displaying values of user-defined and automatic macro variables in the SAS log

Advanced Programming Techniques

  • Demonstrate advanced data set processing techniques such as updating master data sets, transposing data, combining/merging data, sampling data, using generation data sets, integrity constraints and audit trails
  • Reduce the space required to store SAS data sets and numeric variables within SAS data sets by using compression techniques, length statements or DATA step views
  • Develop efficient programs by using advanced programming techniques such as permanent formats and array processing
  • Use SAS System options and SAS data set options for controlling memory usage
  • Control the processing of variables and observations in the DATA step
  • Create sorted or indexed data in order to avoid unnecessary sorts, eliminate duplicate data and to provide more efficient data access and retrieval
  • Use PROC DATASETS to demonstrate advanced programming skills (e.g. renaming columns, displaying metadata, creating indexes, creating integrity constraints, creating audit trails)
