["Claus Ibsen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAMEL-4350?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Claus Ibsen updated CAMEL-4350:
-------------------------------

    Component/s: camel-sql
                 camel-jdbc
        Summary: Camel-jdbc with List<Map> has arbitrary column order  (was: Camel-csv with List<Map> has arbitrary column order)

Assuming its the camel-jdbc component, which is shown above.
The same issue could apply for camel-sql

> 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>
