Sample SAS Advanced Programming Practice Questions

Try these sample questions to test your SAS Advanced Programming exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the basic syntax for creating a table with PROC SQL in SAS?
A.CREATE DATA table
B.PROC SQL; CREATE TABLE name AS SELECT columns FROM source; QUIT;
C.MAKE TABLE name FROM source
D.BUILD TABLE name USING SELECT
Explanation: PROC SQL uses standard SQL syntax. CREATE TABLE creates a new SAS dataset from query results. The SELECT clause specifies columns, FROM identifies the source, and WHERE filters rows. QUIT terminates PROC SQL.
2How do you perform an inner join using PROC SQL?
A.MERGE a b; BY key;
B.SELECT * FROM t1 INNER JOIN t2 ON t1.key = t2.key
C.SELECT * FROM t1, t2 WHERE t1.key MATCHES t2.key
D.PROC JOIN t1 t2 ON key
Explanation: INNER JOIN returns only rows with matching keys in both tables. The ON clause specifies the join condition.
3What does the GROUP BY clause do in PROC SQL?
A.Groups related tables
B.Groups rows sharing common values, enabling aggregate functions to compute per-group results
C.Sorts the output
D.Groups variables by type
Explanation: GROUP BY partitions rows into groups based on column values. Aggregate functions (SUM, AVG, COUNT, MIN, MAX) then compute results for each group.
4How do you use a subquery in PROC SQL?
A.Subqueries are not supported
B.Use a SELECT within WHERE: WHERE col IN (SELECT col FROM other_table)
C.Use a nested DATA step
D.Use PROC SUBQUERY
Explanation: Subqueries in PROC SQL filter data based on another query. Non-correlated subqueries are independent of the outer query. Correlated subqueries reference the outer query.
5What is the HAVING clause used for in PROC SQL?
A.Having a condition on SELECT
B.Filtering groups after GROUP BY aggregation, unlike WHERE which filters rows before grouping
C.Identical to WHERE
D.Having output to a file
Explanation: HAVING filters aggregated groups. WHERE filters rows before grouping. Example: HAVING AVG(salary) > 50000 returns only groups whose average exceeds the threshold.
6How do you use DICTIONARY tables in PROC SQL?
A.Import a dictionary file
B.Query DICTIONARY.TABLES, DICTIONARY.COLUMNS, etc. to access SAS metadata
C.Create a DICTIONARY dataset manually
D.Use PROC DICTIONARY
Explanation: DICTIONARY tables are read-only virtual tables providing metadata about SAS libraries, datasets, variables, macros, and system options. They enable dynamic, data-driven programming.
7What does SELECT DISTINCT do in PROC SQL?
A.Selects all rows
B.Eliminates duplicate rows, returning only unique combinations of selected columns
C.Distinguishes character from numeric columns
D.Creates distinct datasets
Explanation: DISTINCT removes duplicate rows from results. It considers all columns in SELECT when determining uniqueness.
8What is the difference between UNION and UNION ALL in PROC SQL?
A.They are identical
B.UNION removes duplicate rows from the combined result; UNION ALL keeps all rows including duplicates and is faster
C.UNION ALL removes duplicates; UNION keeps them
D.UNION combines columns; UNION ALL combines rows
Explanation: UNION combines results and removes duplicates (slower). UNION ALL stacks all rows without duplicate removal (faster). Use UNION ALL when duplicates are acceptable or impossible.
9How do you use the CALCULATED keyword in PROC SQL?
A.To perform database-level calculations
B.To reference a column alias defined earlier in the same SELECT clause without repeating the expression
C.To use a calculator function
D.To calculate row counts
Explanation: CALCULATED allows referencing aliases in the same SELECT: SELECT price*qty AS total, CALCULATED total*0.1 AS tax. Without it, you would need to repeat the full expression.
10How do you create an index using PROC SQL?
A.PROC INDEX
B.CREATE INDEX index_name ON table(column)
C.ADD INDEX column TO table
D.INDEX table BY column
Explanation: CREATE INDEX index_name ON table(column); creates a simple index. CREATE UNIQUE INDEX creates a unique index. Indexes improve query performance for WHERE conditions and joins on indexed columns.
