    INSERT - Add a new record into the database table.
    UPDATE - If record is available it modifies it.
    MODIFY - If record is available it updates the record otherwise it creates a new record.

    This means MODIFY can do the job for both UPDATE as well as INSERT.

    Whenever you need to create new records in the database table use INSERT. Whenever using INSERT be sure that a duplicate entry having the same values for the primary key fields are not present. Else it may throw a dump.

    When you use MODIFY it makes a check for the matching key field values. If present it modifies the matching record, else it creates a new record in the database table.

    Update WON'T add new record(s), but modify will.
