Why can a SQLite INTEGER column contain text?
KitForma editorial guide. Ordinary SQLite tables use type affinity rather than the rigid typing behavior many developers expect from other databases. Affinity attempts conversion but is not a universal type rejection rule.
Step-by-step guidance
Ordinary SQLite tables use type affinity rather than the rigid typing behavior many developers expect from other databases. Affinity attempts conversion but is not a universal type rejection rule.
For stricter contracts, evaluate STRICT tables in a supported SQLite version and add appropriate constraints. Test numeric text, nonnumeric text, NULL and out-of-range values. Verify the stored value using
typeof, not only a UI column label. Existing permissive data needs migration validation before changing the schema. Strict typing still does not establish business rules such as positive quantities or valid date formats.Sources and verification
