Re: Virtual select distinct list from datasource

[kieran]

I have added an example below of how to get the distinct set of results (using _.uniqBy) . For more information on this function or any other useful functions please have a look at : https://lodash.com/docs/4.17.15

function (source, callback) {
    var result = {
      "columns": ["exchangeName"],
      "meta": { "exchangeName": 11},
      "rows": []
    }
    result.rows= _.uniqBy(source.rows,"exchangeName");
    callback(result);
}
