我有一个mysql原生查询,如何将相同的mysql转换成jpql,就像我在项目中使用jpa和springboot一样。
以下是mysql查询,运行良好:
select title0_.title_id as title_id1_15_, title0_.title_categorystudio_id as title_ca3_15_, title0_.title_name as title_na2_15_
from title title0_
inner join title_language languages1_ on title0_.title_id=languages1_.titlelanguage_titleid
inner join language language2_ on languages1_.titlelanguage_languageid=language2_.language_id
inner join title_genre genres3_ on title0_.title_id=genres3_.titlegenre_titleid
inner join genrescategory genrescate4_ on genres3_.titlegenre_genreid=genrescate4_.genrescategory_id
left join (movie movies5_ inner join studioname studio8_ on movies5_.movie_studio_id=studio8_.studioname_id) on title0_.title_id=movies5_.movie_titleid
left join (tvshow tvshows6_ inner join studioname studio9_ on tvshows6_.tv_studio_id=studio9_.studioname_id) on title0_.title_id=tvshows6_.tv_titleid
left join (kid kids7_ inner join studioname studio10_ on kids7_.kid_studio_id=studio10_.studioname_id) on title0_.title_id=kids7_.kid_titleid
inner join categorystudio categoryof11_ on title0_.title_categorystudio_id=categoryof11_.categorystudio_id
where 1=1
and (language2_.language_name in ('english'))
and (genrescate4_.genrescategory_name in ('action'))
and (categoryof11_.categorystudio_title in ('tv'))
and (studio8_.studioname_name in ('sony') or studio9_.studioname_name in ('sony') or studio10_.studioname_name in ('sony'))
我使用的是一个不起作用的jpql查询,
@Query("select t from Title t " +
"join t.languages l " +
"join t.genres g " +
"left join t.movies m join m.studio ms " +
"left join t.tvShows tv join tv.studio tvs " +
"left join t.kids k join k.studio ks " +
"join t.categorystudio c where l.languageName IN (:languages) AND g.name IN (:genres) AND c.categorystudio_title IN (:categories) AND (ms.name IN (:studios) OR tvs.name in (:studios) OR ks.name IN (:studios))")
在日志中,jpql查询显示为:
select title0_.title_id as title_id1_15_, title0_.title_categorystudio_id as title_ca3_15_, title0_.title_name as title_na2_15_ from title title0_
inner join title_language languages1_ on title0_.title_id=languages1_.titlelanguage_titleid
inner join language language2_ on languages1_.titlelanguage_languageid=language2_.language_id
inner join title_genre genres3_ on title0_.title_id=genres3_.titlegenre_titleid
inner join genrescategory genrescate4_ on genres3_.titlegenre_genreid=genrescate4_.genrescategory_id
left outer join movie movies5_ on title0_.title_id=movies5_.movie_titleid inner join studioname studio6_ on movies5_.movie_studio_id=studio6_.studioname_id
left outer join tvshow tvshows7_ on title0_.title_id=tvshows7_.tv_titleid inner join studioname studio8_ on tvshows7_.tv_studio_id=studio8_.studioname_id
left outer join kid kids9_ on title0_.title_id=kids9_.kid_titleid inner join studioname studio10_ on kids9_.kid_studio_id=studio10_.studioname_id
inner join categorystudio categoryof11_ on title0_.title_categorystudio_id=categoryof11_.categorystudio_id
where (language2_.language_name in (?)) and (genrescate4_.genrescategory_name in (?)) and (categoryof11_.categorystudio_title in (?)) and (studio6_.studioname_name in (?) or studio8_.studioname_name in (?) or studio10_.studioname_name in (?))
提前谢谢。
