UPSERT is a clause added to INSERT that causes the INSERT to behave as an UPDATE or a no-op if the INSERT would violate a uniqueness constraint. UPSERT is not standard SQL. UPSERT in SQLite follows the syntax established by PostgreSQL, with generalizations. https://www.sqlite.org/lang_upsert.html The REPLACE command is not used, since it deletes and inserts: https://www.sqlite.org/lang_replace.html https://www.sqlite.org/lang_conflict.html
