·         Replacing the statements

The action of replacing the item is performed in a row. The action of replacement is more dependent on the id as in order to REPLACE effectively one has to add the column of PRIMARY. Once the primary column has been set as id the system will be familiar as to which row the necessary action has to be performed.  Consequently if the id is not specified system will have no information of which row one has intended to bring changes.

In the statements where id is not specified to the system it will act more like an INSERT action. In simple words if the primary row is specified the changes will be made only in concerned row.
