SQLite✓ Tested
Divide an ordered result into numbered buckets
SQLite: NTILE distributes rows across buckets; include a unique tie-breaker for deterministic assignment.
SQLite✓ Tested
Enforce a bounded numeric range
SQLite: A named CHECK constraint keeps numeric values inside an inclusive interval.
SQLite✓ Tested
Enforce a relationship between two columns
SQLite: A row-level CHECK can require a start value to be no greater than an end value.
SQLite✓ Tested
Enforce uniqueness with a dedicated index
SQLite: A unique index rejects a duplicate combination independently of query plans.
SQLite✓ Tested
Expose a reusable filtered view
SQLite: A view stores a query definition rather than a snapshot of its rows.
SQLite✓ Tested
Filter by a numeric comparison
SQLite: Keep rows whose quantity exceeds a chosen threshold.
SQLite✓ Tested
Filter groups after aggregation
SQLite: Use HAVING to test a group’s calculated total.
SQLite✓ Tested
