子树JPQL意外结束

Question

我有一个查询，该查询从4个表计数给定代码。 我首先在postgresql中测试了此查询，它按预期工作，因此尝试将其翻译为JPQL并收到此错误：

java.lang.IllegalArgumentException: 
org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected end of 
subtree [ select ((select count(*) from *.Record r where 
r.codeCampaign =?1 ) +  (select count(*) from *.AccountAssociationAction aaa where aaa.codeCampaign = ?1) + 
(select count(*) from *.CampaignPayment cp where cp.pk.campaignCode = ?1) + (select count(*) from 
*.ActionPeriodDepartment apd
where apd.id.codeCampaign = ?1))]

我无法弄清楚什么是错误的，而Hibernate所表示的“子树的意外末尾”是什么意思

PostgreSQL查询：

select  (select count(*) from account_association_action aaa where 
aaa.code_campaign = 'CAMP01') + (select count(*) from _campaign_payment cp 
where cp.campaign_code = 'CAMP01') + (select count(*) from record r where 
r.code_campaign ='CAMP01') + (select count(*) from action_period_department apd 
where apd.code_campaign = 'CAMP01'); 

JPQL查询：

@Query(value=" select (select count(*) from Record r where r.codeCampaign =?1 ) + " +
" (select count(*) from AccountAssociationAction aaa where aaa.codeCampaign = ?1) +" +
" (select count(*) from CampaignPayment cp where cp.pk.campaignCode = ?1) +" +
" (select count(*) from ActionPeriodDepartment apd where apd.id.codeCampaign = ?1)")
int countCampaignCodeUses(String campaignCode);

Answer 1

它看起来像你需要添加nativeQuery=true到@Query注释，否则JPA未能进行查询的意识，而不from
