> Given class A with one to many relations to class B, when trying to get paginated data with SQLServerDialect from class A with a join clause to class B will dublicated A instances. That is because the row_number function will introduce another value to the select statement which will alway be different for each row. I found a work around using group by. Did not have time finish the test cases yet.
