  • Reset 'count' every time the channel starts.

    Hi

    I've created a channel at Mirth 1.7 that uses a database connection at source and a file writer at destination, creating a Worklist DICOM file per message.

    This channel starts by time polling, running once every day.

    The SQL at the source sections retrieves a lot of records that become the same amount of messages.

    I need to put a counter in the destination files name that began from "1" and ends at number of messages by every time the channel starts.

    I can do something like this with "Count" variable in Destination Mappings, but i don't know how to reset this counter to "1" by the next time the channel starts.

    Please, could you give me some advice?

    I wonder if the pre/post processor scripts could be useful for that, but I don't know exactly how they work.

    Regards

    Re:Reset 'count' every time the channel starts.

    If you set up your source connector to use JS, you can define a new variable called i.e counter, with a value of 0 and then push it to the channel map.

    Then, in your file writer destination, you can define a JS transformer that gets this variable from the channel map, add +1 to its value and then push it again to the channel map.

    Finally in your file writer destination you'll get a new variable called
    "counter" that will be reseted every time the channel executes the reading (one time every day), and it's increased by 1 for any message that processses.

    If you don't get the "counter" var increased for every message, you can try to do the inc in the postprocessor step.

    Hope that helps!
