Window ROW_NUMBER
Learn Window ROW_NUMBER in SQLite through the exact construct, a dedicated example, a boundary case, and a mastery check.
Window ROW_NUMBER is an atomic SQLite lesson inside Advanced SQLite. 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 Window ROW_NUMBER rather than on generic SQLite syntax.
Topic-specific example
SELECT id,ROW_NUMBER() OVER (ORDER BY total DESC) rn FROM orders;
Test Window ROW_NUMBER 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.
