How to get sub topic related to selected Topic in apex?

Hi All,

I' creating a question from community. Question can be created  from either Topic or Group. When ever i'm creating question there is an option to add sub topic related to selected Topic. I need to distinguish between primary topic and subtopic. How can i query subtopic related to selected primary topic in apex.

Please let me know if there is any workaround.

Thanks!

Hi Praneetha,

Please use below soql query : - 

List<PrimaryTopic> lst_Primary = new List<PrimaryTopic>([Select Id,fields,(Select Id,fields from subTopic__r) from primaryTopic]);

Something as shown in above will be used.

Please let me know, if it works :)

Thanks

Hi rajat,

Thanks for reply. Actually i need subtopic related to Topic (Standard object).

I need to get Topic and SubTopic related to feedItem. I'm getting Topic Id related to FeedItem from TopicAssignment object like below.

List<TopicAssignment> myFeedItemFeedAssignments = [SELECT Id, NetworkId, TopicId, Topic.Name, EntityId
                                                   FROM TopicAssignment
                                                   EntityId IN  : feedItemId];
                                                   
I will get TopicId but not able to get SubTopics. I didn't find any field on Topic object related to subtopic.  Please suggest if there is any way to get SubTopics related to Topic
