1. Accessing Data Using SQL

Generate detail reports by working with a single table, joining tables, or using set operators in the SQL procedure.

• Retrieve rows that satisfy a condition.
• Use the SELECT statement.
• Validate a query.
• Join tables - inner joins, full joins, right joins, left joins.

• Sort data.
• Select columns in a table.

Generate summary reports by working with a single table, joining tables, or using set operators in the SQL procedure.

• Group data.
• Summarize data.
• Filter grouped data.

Construct sub-queries and in-line views within an SQL procedure step.

• Subset data by using non-correlated subqueries (HAVING clause).
• Subset data by using correlated subqueries.
• Reference an in-line view with other views or tables (multiple tables).

• Alter columns attributes.
• Use SAS data set options with PROC SQL.
• Delete rows.

Access Dictionary Tables using the SQL procedure.

• Use the DESCRIBE TABLE statement.
• Access SAS system information by using DICTIONARY tables.

2. Macro Processing

Create user-defined and automatic macro variables within the SAS Macro Language.

• Use %INPUT statement.
• Use INTO clause of the SELECT statement in SQL.
• Use %LOCAL statement.
• Use %GLOBAL statement.
• Use the SYMPUT and SYMPUTX routine in the DATA Step.
• Use the SYMGET function to return the value of a macro variable to the DATA step during DATA step execution.
• Define Macro variables.

Automate programs by defining and calling macros using the SAS Macro Language.

• Use the %MACRO statement.
• Generate SAS Code conditionally by using the %IF-%THEN-%ELSE macro statements or iterative %DO statements.
• Pass information into a macro using parameters.
• Define a macro.
• Insert comments into macros.

Understand the use of macro functions.

• Use the %MACRO statement.

• Pass information into a macro using parameters.
• Define a macro.
• Insert comments into macros.

Use various system options that are available for macro debugging and displaying values of user-defined and automatic macro variables in the SAS log.

• Examine macro variable resolution with SYMBOLGEN.
• Examine the generated SAS statements with MPRINT.
• Trace the flow of execution with MLOGIC.
• Use the %PUT statement to track problems.
• Use system options to track problems.

Create data-driven programs using SAS Macro Language.

• Generate repetitive macro calls using the %DO loop, macro variable, and the EXECUTE routine.
• Use indirect reference to macro variables.
• Create macro variables with a list of values.

3. Advanced Programming Techniques

Demonstrate the use of advanced data look-up techniques such as array processing, hash objects, formats, and merging.

• Combine multiple data sets using FILEVAR= option.
