问题
I would just like to check - for the QueryDSL version 3.1.1. - is it still impossible to join with a subquery, as is written in an answer here: JPQL / QueryDSL: join subquery and get aliased column
回答1:
Yes, still the same restriction. The restriction comes from JPA, so there is not much to be done about it in Querydsl.
