ROLLUP

Learn ROLLUP in Oracle SQL through the exact construct, a dedicated example, a boundary case, and a mastery check.

10 min read • Intermediate

ROLLUP is an atomic Oracle SQL lesson inside Aggregation & Sets. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.

Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on ROLLUP rather than on generic Oracle SQL syntax.

Topic-specific example

oraclesql-04-03.sql
sql Try It Live
SELECT region,channel,SUM(total) FROM sales GROUP BY ROLLUP(region,channel);
Edge case / engineering note

Test ROLLUP with an empty result, NULL/missing value, duplicate key, or concurrent operation where relevant; database behavior should be verified at the boundary shown by this example.
