Aggregation of data model

You can use a!queryEntity to query the data. The query parameter of that function can be passed query aggregations to perform. QueryEntity performs better than query rules and allows for easy paging of retrieved data as well. Read up on the linked documentation to receive all the information you should need to use the function properly.

 

If you are trying to perform aggregation on data that is not queried from the database, I believe you would have to write your own custom expression rules to do that unless there is a plug-in that fulfills that purpose.

Yes the data is available on a cdt .

, AFAIK, there is no out of the box function available. Try with filter() , if it suits your requirement.

data being returned by a expression/CDT(Querr Rule)-- If you are getting data from query rule, creating one more rule for only aggregation on the CDT data with query entity will be Ok but, Why cannot you query the aggregation data directly using queryEntity.

I was looking to do about 3 different aggregations (different conditions) on a single table and was looking to fetch the data in one go.

If you want to apply multiple aggregation on a table on different condition than why you are not aggregation on conditions in queryentity()
like - if(ri!abc="a",aggregation1,if(ri!abc="b",aggregation2,aggregation3))

I need data from all the three aggregations not like based on any conditions i will execute aggregation1 or 2 or 3 ...
