SQLite strict tables best practice, directly actionable for data engineering.

Summary

SQLite's strict tables enforce rigid typing for columns, preventing insertion of mismatched types like text into INTEGER columns and rejecting bogus column types such as DATETIME or JSON. Only INT, INTEGER, REAL, TEXT, BLOB, and ANY are permitted, and existing tables cannot be altered to strict—requiring a manual data migration. This feature brings SQLite closer to traditional SQL database type safety without sacrificing its lightweight footprint.
