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?
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
“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.
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true ">
<attribute name="gropupid" />
Hope this helps.
