select NEW org.UserDto(distinct(orgreg.contactNumber)) from OrganisationRegistration orgreg

The above query throws runtime exception due to distinct keyword.

Is there any solution available.

DISTINCT only applies to the entire query (the only exception is its usage with an aggregate function).

Select distinct NEW org.UserDto(orgreg.contactNumber) from OrganisationRegistration orgreg
