📄️ Join Introduction
Understand why joins matter and how SQLite combines related rows from multiple tables.
📄️ INNER JOIN
Use INNER JOIN in SQLite to return only rows that have matching keys in both joined tables.
📄️ LEFT JOIN
Use LEFT JOIN in SQLite to keep all rows from the left table even when no matching row exists on the right.
📄️ CROSS JOIN
Use CROSS JOIN in SQLite to generate all combinations between two tables when Cartesian products are intentional.
📄️ SELF JOIN
Join a table to itself in SQLite to model relationships like manager-employee hierarchies.
📄️ Join Best Practices
Apply practical SQLite join guidelines for correctness, readability, and performance as queries become more complex.
