Get affected-rows value from mysql DB using Mule 3.5.x+ - mysql

Question

On attempting to write to a table, I need to know if the row was updated (new row created or existing row updated) or not. I would have got this value from the affected-rows value.
Previously, the solution would have been to build a class like org.mule.transport.jdbc.sqlstrategy.SimpleUpdateSqlStatementStrategy and re-implement it to return the affected-rows value instead of the row itself.
However, it seems like the JDBC transport has been deprecated in favor of the Database connector, and I am finding it hard to track down the code or how to implement the functionality.
SOLUTION :
David's reply got me down the right track! Thanks David.
However, this problem was fixed in the mysql-connector-java in versions 5.1.27 and above.
So, the POM needed to be upgraded.
mysql
mysql-connector-java
5.1.27
I was able to achieve the right results using DBCP2 as follows:
<spring:beans>
<spring:bean id= "jdbcDataSource" class ="org.apache.commons.dbcp.BasicDataSource" name= "Bean">
<spring:property name= "driverClassName" value ="com.mysql.jdbc.Driver" />
<spring:property name= "username" value = "root"/>
<spring:property name= "password" value = "root"/>
<spring:property name="url" value="jdbc:mysql://localhost:3306/local1?useAffectedRows=true"/>
<!-- Following properties added for having auto reconnect mechanism-->
<spring:property name= "testOnBorrow" value = "true"/>
<spring:property name= "validationQuery" value = "select 1"/>
</spring:bean>
</spring:beans> <db:mysql-config name="MySQL_Configuration" dataSource-ref="jdbcDataSource" doc:name="MySQL_Configuration"/>

Answer 1

From the documentation:
target #[payload] The enricher expression used to enrich the current message with the result of the SQL processing.
This should allow you to define an expression that would tell Mule where to store the outcome of the update, which is the number of updated rows.
From the integration test suite:
<db:update config-ref="dbConfig"
target="#[header:OUTBOUND:updateCount]">
<db:parameterized-query>update PLANET set NAME='Mercury' where POSITION=4</db:parameterized-query>
</db:update>
This sets an outbound property named updateCount with the number of updated rows. I'd personally suggest to instead set a flow variable with #[flowVars['updateCount']], but it depends on your use case.
