EXPLAIN QUERY PLAN
Learn EXPLAIN QUERY PLAN in SQLite through the exact construct, a dedicated example, a boundary case, and a mastery check.
EXPLAIN QUERY PLAN is an atomic SQLite lesson inside Indexes & Query Planner. 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 EXPLAIN QUERY PLAN rather than on generic SQLite syntax.
Topic-specific example
EXPLAIN QUERY PLAN SELECT * FROM users WHERE email='a@example.com';
Test EXPLAIN QUERY PLAN 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.
