Objective   Details
Accessing Data Using SQL
Generate detail reports by working with a single table, joining tables, or using set operators in SQL – Use PROC SQL to perform SQL queries.
– Select columns in a table with a SELECT statement and FROM clause.
– Create a table from a query result set.
– Create new calculated columns.
– Assign an alias with the AS keyword.
– Use case logic to select values for a column.
– Retrieve rows that satisfy a condition with a WHERE clause.
– Subset data by calculated columns with the CALCULATED keyword.
– Join tables – inner joins, full joins (coalesce function), right joins, left joins, cross joins.
– Combine tables using set operators – union, outer join, except, intersect.
– Sort data with an ORDER BY clause.
– Assign labels and formats to columns.
Generate summary reports by working with a single table, joining tables, or using set operators in the SQL. – Summarize data across and down columns using summary functions (AVG, COUNT, MAX, MIN, SUM).
– Group data using GROUP BY clause.
– Filter grouped data using HAVING clause.
– Eliminate duplicate values with the DISTINCT keyword.
Construct sub-queries and in-line views within an SQL procedure step. – Subset data by using non-correlated subqueries.
– Reference an in-line view with other views or tables (multiple tables).
Use special features of the SQL procedure. – Use SAS data set options with PROC SQL (KEEP=, DROP=, RENAME=, OBS=).
– Use PROC SQL invocation options (INOBS=, OUTOBS=. NOPRINT, NUMBER)
– Use PROC SQL with the SAS Macro Facility to create macro variables with the INTO keyword.
– Use SAS functions (SCAN, SUBSTR, LENGTH).
– Access SAS system information by using DICTIONARY tables (members, tables, columns)
Macro Processing
Create and use user-defined and automatic macro variables within the SAS Macro Language. – Define and use macro variables.
– Use macro variable name delimiter. (.)
– Use INTO clause of the SELECT statement in SQL.
– Use the SYMPUTX routine in a DATA Step.
– Control variable scope with:
%GLOBAL statement
%LOCAL statement
SYMPUTX scope parameter
Automate programs by defining and calling macros using the SAS Macro Language. – Define a macro using the %MACRO and %MEND statements.
– Insert comments into macros.
– Pass Information into a macro using parameters.
– Generate SAS Code conditionally by using the %IF-%THEN-%ELSE macro statements or iterative %DO statements.
Use macro functions. – Use macro character functions. (%SCAN, %SUBSTR, %INDEX, %UPCASE)
– Use macro quoting functions. (%NRSTR, %STR)
– Use macro evaluation functions. (%EVAL)
– Use %SYSFUNC to execute DATA step functions within the SAS Macro Language.
Debug macros. – Trace the flow of execution with the MLOGIC option.
– Examine the generated SAS statements with the MPRINT option.
– Examine macro variable resolution with the SYMBOLGEN option.
– Use the %PUT statement to print information to the log.
Create data-driven programs using SAS Macro Language. – Create a series of macro variables.
– Create a macro variable containing a delimited list of values using PROC SQL.
– Use indirect reference to macro variables. (&&, etc)
– Generate repetitive macro calls using:
the %DO loop,
SQL query with SELECT INTO
DATA Step with DOSUBL or the EXECUTE routine function.
Advanced Techniques
Process data using 1 and 2 dimensional arrays. – Define and use character arrays.
– Define and use numeric arrays.
– Create variables with arrays.
– Reference arrays within a DO loop.
– Specify the array dimension with the DIM function.
– Define arrays as temporary arrays.
– Load initial values for an array from a SAS data set.
Process data using hash objects – Declare hash and hash iterator objects
Dataset argument
Ordered argument
Multidata argument
– Use hash object methods
definekey()
definedata()
definedone()
find()
add()
output()
– Use hash iterator object methods
first()
next()
last()
prev()
– Use hash objects as lookup tables.
– Use hash objects to create sorted data sets.
– Use hash iterator objects to access data in forward or reverse key order.
Use SAS utility procedures – Specify a template using the PICTURE statement within the FORMAT Procedure
Specify templates for date, time, and datetime values using directives.
Specify templates for numeric values using digit selectors.
– Create custom functions with the FCMP procedure
Create character and numeric custom functions with single or multiple arguments.
Create custom functions based on conditional processing.
Use custom functions with the global option CMPLIB=.
