I have a flow something like this
A 'Database inbound endpoint' which polls(for every 5 mins) to mySQL Database-Server and get result-set by a select-query (automatically this becomes the current payload i.e #[message.payload])
'For each' component and a 'Logger' component in it using a expression as #[message.payload]
Now flow has one more 'Database-out-bound-endpoint' component which executes another select-query and obtains result-set.
'For each' component with a 'Logger' component in it using a expression as #[message.payload]
Note: in the loggers result-set of first DB is printing. I mean second logger is also showing result-set of first query itself.Because the result-set is storing as payload
so, my questions are
what is the MEL to read the result-set of second database-query in the above scenario.
is there any another way to read result-set in the flow
Here is the configuration XML
<jdbc-ee:connector name="oracle_database" dataSource-ref="Oracle_Data_Source" validateConnections="true" queryTimeout="-1" pollingFrequency="0" doc:name="Database"/>
<flow name="testFileSaveFlow3" doc:name="testFileSaveFlow3">
<poll frequency="1000" doc:name="Poll">
<jdbc-ee:outbound-endpoint exchange-pattern="one-way" queryKey="selectTable1" queryTimeout="-1" connector-ref="oracle_database" doc:name="get data from table 1">
<jdbc-ee:query key="selectTable1" value="SELECT * FROM TABLE1"/>
</jdbc-ee:outbound-endpoint>
</poll>
<foreach doc:name="For Each">
<logger message="#[message.payload]" level="INFO" doc:name="prints result-set of table1"/>
</foreach>
<jdbc-ee:outbound-endpoint exchange-pattern="one-way" queryKey="selectTable2" queryTimeout="-1" connector-ref="oracle_database" doc:name="get data from table 2">
<jdbc-ee:query key="selectTable2" value="SELECT * FROM TABLE2"/>
</jdbc-ee:outbound-endpoint>
<foreach doc:name="For Each">
<logger message="#[message.payload]" level="INFO" doc:name="prints result-set of table2"/>
</foreach>
</flow>
thanks in advance.
