-REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted.
+REPLACE delete the old rows when the new row conflict with the old row which contains PRIMARY KEY or a UNIQUE index, and then insert the new row.
