The problem with REPLACE is: " the REPLACE algorithm deletes pre-existing rows that are causing the constraint violation prior to inserting or updating the current row"
When using REPLACE with a table containing a?foreign key clause ON DELETE CASCADE causes data in other tables to be deleted. Postgres recently implemented the UPSERT command in 9.5. I was just wondering if SQLite will decide to implement it or not, or if there is some reason they have chosen not to.
