JPA添加Pageable实现翻页时报错

@Query("from Subject where name like CONCAT('%',:name,'%') and isDelete = 0 order by createTime desc")Page findSubjectByName(@Param("name") String name, Pageable page);

报错：

select count(where) from com.swj.entity.Subject where name like CONCAT('%',:name,'%') and isDelete = 0

添加别名就可以解决

@Query("select t from Subject t where t.name like CONCAT('%',:name,'%') and t.isDelete = 0 order by createTime desc")Page findSubjectByName(@Param("name") String name, Pageable page);
