Spring Integration - JDBC channel adaptar without query result

I have a problem when my query return null or cero result inside resultset.

I have a int-jdbc:inbound-channel-adapter with a rowMapper

<int-jdbc:inbound-channel-adapter query="SELECT * FROM ENGINE_LOGS WHERE COUNTRY_ID = 2 AND BUSINESS_ID = 100 and rownum &lt; 10"   
    channel="oracle.db.resultSet.engineLogs"
    update="" 
    row-mapper="engineLogsRowMapper"
    data-source="jdbcTemplate">
    <!-- Cron Time -->
    <int:poller fixed-rate="5" time-unit="SECONDS"></int:poller>
</int-jdbc:inbound-channel-adapter>`

When the query return null o cero (0) result, the row mapper class or the transformer (with input-channel: oracle.db.resultSet.engineLogs) never call.

I need execute an update in a auxiliary database if the query not find records in database, is it possible add a router or something to fix my problem?
