DataFactory sink from variable array?

Klaus Nørregaard 1 Reputation point


I am looking for the best strategy or method to sink from a defined pipeline array. I have with success created a foreach loop, that iterates over a list of objects. Then each object have been stored within a Pipeline variable of type Array. Now I would like to sink the array to csv. How to do that?

    Hello @Klaus Nørregaard , @Ryan Abbey . Welcome to Microsoft Q&A.

    I don't want to interrupt the great collaboration you have going on, but I thought of suggesting another way.

    If you just need to get the data from a web-based source, use the HTTP dataset or the REST dataset. Web activity is more for getting meta-data.

    Web activity can be used to write via leveraging a storage api.

    It is also possible to write from an array by using the "additional column" feature in a delimited text dataset. The trick in this, is to use an almost-empty file as source, put the array into additional column, and map to sink.

    This was left unanswered but the way to do it is to store the output from the HTTP Request into a variable using the set variable, if there are subsequent HTTP calls then you'll require a ForEach loop that appends to your variable. Once that is done you'll need to pass your data to a JSON output you can use "add additional columns" and use the expression builder to access your variable. variables('variable1') and it will add this to your output.
