I want to get result as
List of @Entity of study_material which will contain List<stydy_material_history> with entities - the max values from study_material_history per day (using rep_date) (for each study_material respectively)

I have 2 tables in mysql

I created entities classes:

for using spring data i create:

to reiterate question
how can i get via findAll()
List of StudyMaterial that will contain List of StudyMaterialHistoryCurrentState than will contains  items that is maximum rep_date per day.
I can`t understand where and how i must changes to get such result
assuming that both tables are filled with data next is sql variant i want express
