Getting distinct values from fetchXML using Liquid

(0) ShareShare
ReportReport
Posted on by Usmani 25

I have a fetchXML that returns data like this

wondering if I can get distinct group IDs using the same fetchXml by using some filter or otherwise have to write a separate query to get distinct groups?

    Hi Usmani,

    Use this syntax in your Fetch XML definition.

    fetch mapping='logical' distinct='true'>

    do you need the list Groups or you just to render as a group

    if you need the list perhaps the easiest way is repeating the fetch only retrieving the GroupId and adding the distinct as per Adrian indication

    if your looping and want to render as a group, I would suggest simply storing in a variable the last GroupId and keep verifying if it has changed

    worst case scenario you can do 2 fetchs.. one for the groups.. while looping, another fetch filtering by the group.. but this will decrease the performance

    Hi Usmani,

    “if I can get distinct group IDs using the same fetchXml by using some filter” – No, you cannot filter it using Fetch XML.

    You have to write separate query to get distinct group.

    For e.g.:

    <fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true ">

     <entity name="group">

       <attribute name="gropupid" />

     </entity>

    </fetch>

    Hope this helps.

    Thanks!
