ROW_NUMBER analytic

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

10 min read • Intermediate

ROW_NUMBER analytic is an atomic Oracle SQL lesson inside Hierarchical & Analytic SQL. 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 ROW_NUMBER analytic rather than on generic Oracle SQL syntax.

Topic-specific example

oraclesql-03-06.sql
sql Try It Live 
SELECT id,total,ROW_NUMBER() OVER(ORDER BY total DESC) rn FROM orders;
Edge case / engineering note

Test ROW_NUMBER analytic 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.
