SQLite “INSERT OR REPLACE INTO” vs. “UPDATE … WHERE”

Question

I\'ve never seen the syntax INSERT OR REPLACE INTO names (id, name) VALUES (1, \"John\") used in SQL before, and I was wondering why it\'s better than UPD

Answer 1

I'm currently working on such a statement and figured out another fact to notice: INSERT OR REPLACE will replace any values not supplied in the statement. For instance if your table contains a column "lastname" which you didn't supply a value for, INSERT OR REPLACE will nullify the "lastname" if possible (constraints allow it) or fail.
