Syntax options:

    FOR EACH ROW | FOR EACH STATEMENT

    Specifies whether the triggered action is evaluated once per
    triggering statement, or for each row of the subject table that
    is affected by the triggering statement.

    If you specify FOR EACH STATEMENT, then the triggered action
    is evaluated only once, and row values are not available to the
    triggered action.

    The FOR EACH STATEMENT clause is the default.
