    detect increase in table size

    Hi,

    I'm currently learning about mirth. I've gone through a few simple examples and now I want to do the following use case.

    - use a database reader to get the size of a table (using select count(*) from mytable)
    - check if that table increased in size (filter count against previous count saved in as a global var)
    - if there is a new record in the database, notify a web service.

    Problem is, I'm in fact stuck on step one!
    select * from mytable works, but count(*) doesn't.

    I get the following error in the System Events window:
    org.mule.umo.routing.RoutingException: Failed to transform message before applying the filter. Failed to route event via endpoint: ImmutableMuleEndpoint{connector=com.webreach.mirth [email protected], endpointUri=jdbc://query, transformer=Transformer{name='ResultMapToXML', returnClass=false, returnClass=false, sourceTypes=[class java.util.HashMap]}, name='_jdbcEndpoint#70137697', type='receiver', properties={}, transactionConfig=org.mule.impl.MuleTransactionCon [email protected], filter=null, deleteUnacceptedMessages=false, initialised=true, securityFilter=null, synchronous=true, initialState=started, createConnector=0}.

    Re:detect increase in table size

    When I do the query from javascript in my database reader, I get the following exception:

    What I'm having now is a very basic channel.
    database reader and file writer. No filters, no transformation.
    Just select count(*) from patients as the SQL statement.

    I must be doing something wrong, because this is so basic, can't imagine where I could have made a mistake.

    Any ideas?

    Kristof.

    PS: mirth config is in attachement

      Try with a column name like,

      SELECT Count(*) AS CurRecCount FROM Patients

      Hope it helps!
