錯誤的HQL子查詢

Question

我運行這個查詢與子查詢的WHERE子句

select prot.id as id, 
      prot.nrProtocolo as nrProtocolo, 
      prot.nrAno as nrAno, 
      prot.cdSituacaoProtocolo as cdSituacaoProtocolo, 
      prot.palavraChave as palavraChave, 
      prot.dsObs as dsObs, 
      prot.dataCriacao as dataCriacao, 
      partAtual as participanteAtual, 
      assunto.id as assunto_id, 
      assunto.nmAssunto as assunto_nmAssunto, 
      tema.id as assunto_tema_id, 
      tema.nmTema as assunto_tema_nome 
    from Evento evt 
    inner join evt.protocolo prot 
    left outer join prot.assunto assunto 
    left outer join assunto.tema tema 
    inner join prot.participanteAtual partAtual 
    where (
      (prot.participanteSubscritor.id = :participanteId and :participanteId is not null) or 
      (upper(prot.nmSubscritor) like :nmParticipante and :nmParticipante is not null) or 
      (prot.participanteEmissor.id = :participanteId and :participanteId is not null) or 
      (upper(prot.nmEmissor) like :nmParticipante and :nmParticipante is not null) or 
      (
       select count(*) from ParticipanteProtocoloEntity pp where pp.protocolo.id = prot.id and 
       ( 
        (pp.participante.id = :participanteId and :participanteId is not null) or 
        (upper(pp.nmParticipante) like :nmParticipante and :nmParticipante is not null) > 0 
       ) 
      ) 
     ) 
      and trunc(prot.dataCriacao) >= trunc(:periodoInicial) and trunc(prot.dataCriacao) <= trunc(:periodoFinal) 
      and prot.cdSituacaoProtocolo <> 4 
      and prot.cdSituacaoProtocolo <> 8 
      and (prot.snExcluido is null or prot.snExcluido != 'S') 
    order by prot.dataCriacao desc, prot.nrProtocolo asc 

內，但我收到此錯誤：

Error in named query: 
Protocolo.recuperaListaProtocoloPorEncaminhadoParticipanteTrans: 
org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected AST node: query 

當我刪除子選擇查詢工作正常。

我不能發現什麼是錯的這一部分：

(
    select count(*) from ParticipanteProtocoloEntity pp where pp.protocolo.id = prot.id and 
       ( 
        (pp.participante.id = :participanteId and :participanteId is not null) or 
        (upper(pp.nmParticipante) like :nmParticipante and :nmParticipante is not null) > 0 
       ) 
)

我看到你得到的ParticipanteProtocoloEntity計數。但它看起來畸形的對我說：

(UPPER(pp.nmParticipante) LIKE :nmParticipante AND :nmParticipante IS NOT NULL) > 0 

看起來像{boolean statement} > 0給我。我猜你想count(*)大於零：

(
SELECT 
    COUNT(*) 
FROM 
    ParticipanteProtocoloEntity pp 
WHERE 
    pp.protocolo.id = prot.id 
AND ((
      pp.participante.id = :participanteId 
     AND :participanteId IS NOT NULL) 
    OR (
      UPPER(pp.nmParticipante) LIKE :nmParticipante 
     AND :nmParticipante IS NOT NULL))) > 0
