Hello, In a!queryEntity() sorting is not supported currently, will it

Have you checked the query recipes page? There are some examples for sorting.

Yes checked, but it does not support for a!queryEntity. Only in query rule sorting is supported

The example below contains sort definition in the paginginfo structure.

forum.appian.com/.../Query_Recipes.html

In this forum.appian.com/.../Querying_Data_From_an_RDBMS.html
they have mentioned that sorting is not supported
even when i apply sort field, it does not apply when we use a!queryEntity

What type of field are you sorting on? Can you share your query code. Sorting via pagingInfo is definitely available in a!queryEntity.

pagingInfo:a!pagingInfo(sort:a!sortInfo(field:"field1", ascending:true))......you can do sorting like this inside a!query()

Also you can use the following plugin for sorting purposes:forum.appian.com/.../summary

I have already used a!sortInfo
but it is not working, Also, we cannot apply for multiple columns........THe field which I used inside a!sortInfo, and when in the grid i Click on the column, it is inot sorting.

You are correct that multiple column sorting is not supported. However sorting the results in a!queryEntity is supported using a!pagingInfo. It is likely that you have made some other error in your interface design. I can only suggest reading the documentation again if you are not able to attach your expression
