问题 I need to grab some records from a table which has a Column birthDate which is a Date (without time). I need to filter records by comparing against year and month only. For example I want all the users born on March of 1990. The day doesn't matter. How do you handle it? 回答1: You can use from Entity where to_char(birthDate,'YYYY/MM') = '1990/03' this will work for HQL 回答2: you may try this select * from table where month(birthdate)=03 and year(birthdate)=1990 来源： https://stackoverflow.com

问题 I have class like public User{ Long id; Set<String> roles; } How do I query all User objects with the role of "ADMIN" EDIT: I'm using Hibernate 3.0.5.
