> The following route works but the order of the columns is dependent on the natural ordering of the hashmap. Target systems will have an expectation of the order of the data. 
> <route>
>   <from uri="jetty:http://0.0.0.0:16081/css/mes"/>
>   <setBody>
>     <constant>SELECT id, value1, value2 FROM mytable</constant> 
>   </setBody>
>   <to uri="jdbc:mydb"/>
>   <marshal>
>     <csv/>
>   </marshal>
>  </route>
> Either there needs to be a property for csv that allows hash key ordering to be specified, or an option to sort the keys, e.g.
> <route>
>   <from uri="jetty:http://0.0.0.0:16081/css/mes"/>
>   <setBody>
>     <constant>SELECT id as col1, value1 as col2, value2 as col3 FROM mytable</constant> 
>   </setBody>
>   <to uri="jdbc:mydb"/>
>   <marshal>
>     <csv sortFields="true" />
>   </marshal>
>  </route>
