Java 可以在JPA中使用窗口函数吗?
我需要在Spring数据存储库中使用窗口函数,是吗 这可能吗 我现在使用的是JavaSpringMaven,对JPA中的实体表分区一无所知 我的SQL查询Java 可以在JPA中使用窗口函数吗?,java,sql-server,jpa,window-functions,Java,Sql Server,Jpa,Window Functions,我需要在Spring数据存储库中使用窗口函数,是吗 这可能吗 我现在使用的是JavaSpringMaven,对JPA中的实体表分区一无所知 我的SQL查询 select b.q_stop_id as q_stop_id, b.q_work_day as q_work_day, b.q_work_end as q_work_end, b.q_mc_num as q_mc_num, b.q_mc_name as q_mc_name, b.Hnbn as q_hnbn, b.q_koku as q_

>我通过使用JPA nativeQuery=true找到了解决方案
如果您使用的是Java13+您可以使用。。。文本块以避免所有字符串连接。
