「運算符不存在：uuid = bytea」Java with Postgres

我在引用此查詢時遇到了問題。在Postgres上，這個查詢執行沒有錯誤。在JAVA上，它會拋出以下異常：「運算符不存在：uuid = bytea」Java with Postgres

javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not extract ResultSet 
cause 
org.postgresql.util.PSQLException: ERROR: operator does not exist: uuid = bytea 
    Note: No operator matches the given name and argument type(s). You might need to add explicit type casts. 
    Position: 404

我該怎麼辦？

我的方法：

public List<CivilRecord> dashboardSearch(CivilRecordSearch civilRecordSearch) 
    throws MessageException { 
    SearchValidation.validateDashboardSearch(civilRecordSearch); 
    List<CivilRecord> l = new ArrayList<>(); 
    try { 
     StringBuilder query = new StringBuilder(); 
     // query.append("select 
     // c.id_civil_record\\:\\:text,c.nm_request,c.nm_rg,c.tx_name,c.dt_register,c.bl_priority 
     // "); 
     query.append("select c.id_civil_record,c.nm_request,c.nm_rg,c.tx_name,c.dt_register,c.bl_priority "); 
     query.append("from sc_civil.tb_civil_record c "); 
     query.append("inner join sc_civil.tb_workflow_record w "); 
     query.append("on w.id_civil_record = c.id_civil_record "); 
     query.append("left join sc_civil.tb_lock l ");

     query.append("where c.id_site = :idSite ");

     if (civilRecordSearch.getRequestNumber() != null) 
      query.append("and c.nm_request = :request "); 

     query.append("order by c.bl_priority desc, c.dt_register "); 

     Query q = em.createNativeQuery(query.toString());

     q.setParameter("canceled", false); 
     if (!StringUtils.isEmpty(civilRecordSearch.getName())) 
      q.setParameter("name", "%" + civilRecordSearch.getName() + "%"); 
     if (civilRecordSearch.getRequestNumber() != null) 
      q.setParameter("request", civilRecordSearch.getRequestNumber()); 
     if (!StringUtils.isEmpty(civilRecordSearch.getRg())) 
      q.setParameter("rg", civilRecordSearch.getRg()); 

     q.setMaxResults(maxResult); 

     List<Object []> lo = q.getResultList(); 
     em.clear(); 
     for (Object [] o : lo) { 
      CivilRecord c = new CivilRecord(); 
      c.setIdCivilRecord(UUID.fromString((String) o[0])); 
      c.setRequest((Long) o[1]); 
      c.setRg((String) o[2]); 
      c.setName((String) o[3]); 
      c.setWorkflowRecords(findStatus(c.getIdCivilRecord())); 
      l.add(c); 
     } 
     return l; 
    } 
    catch (Exception e) { 
     log.severe(e.getMessage()); 
     throw e; 
    } 
}

在數據庫中是什麼類型的'tb_lock.idUser'？你可以嘗試'q.setParameter（「idUser」，civilRecordSearch.getIdUser（）。toString（））'？ – 2014-10-31 12:50:48

tb_lock.iduser是UUID在數據庫中。 – 2014-10-31 13:20:55

你在使用休眠嗎？註釋？ – 2014-10-31 13:25:08

我解決我的問題，這種形式：我利用我的UUID領域命令CAST

public List<CivilRecord> dashboardSearch(CivilRecordSearch civilRecordSearch) 
     throws MessageException { 
    SearchValidation.validateDashboardSearch(civilRecordSearch); 
    List<CivilRecord> l = new ArrayList<>(); 
    try { 
     StringBuilder query = new StringBuilder(); 
     //query.append("select c.id_civil_record\\:\\:text,c.nm_request,c.nm_rg,c.tx_name,c.dt_register,c.bl_priority "); 
     query.append("select CAST(c.id_civil_record as text),c.nm_request,c.nm_rg,c.tx_name,c.dt_register,c.bl_priority "); 
     query.append("from sc_civil.tb_civil_record c "); 
     query.append("inner join sc_civil.tb_workflow_record w "); 
     query.append("on w.id_civil_record = c.id_civil_record "); 
     query.append("left join sc_civil.tb_lock l "); 
     query.append("on l.id_record = c.id_civil_record "); 
     query.append("where c.id_site = :idSite "); 

     if (civilRecordSearch.getPriority() == null || civilRecordSearch.getPriority().equals(false)) 
     query.append("and c.bl_priority = :priority "); 
     query.append("and c.bl_canceled = :canceled "); 
     query.append("and w.id_type_workflow = :idTypeWorkflow "); 
     query.append("and w.id_type_status_workflow = :idTypeStatusWorkflow "); 

     query.append("and (l is null or l.id_user = CAST(:idUser AS uuid)) "); 

     if (!StringUtils.isEmpty(civilRecordSearch.getName())) 
     query.append("and c.tx_name ilike :name ");

     query.append("and c.nm_request = :request "); 

     query.append("order by c.bl_priority desc, c.dt_register "); 

     Query q = em.createNativeQuery(query.toString()); 
     q.setParameter("idSite", civilRecordSearch.getSite().getId());

     q.setParameter("name","%" + civilRecordSearch.getName() + "%"); 
     if (civilRecordSearch.getRequestNumber() != null) 
     q.setParameter("request", civilRecordSearch.getRequestNumber()); 
     if (!StringUtils.isEmpty(civilRecordSearch.getRg())) 
     q.setParameter("rg", civilRecordSearch.getRg()); 

     q.setMaxResults(maxResult); 
     List<Object[]> lo = q.getResultList(); 
     em.clear(); 
     for(Object[] o : lo){ 
      CivilRecord c = new CivilRecord(); 
      c.setIdCivilRecord(UUID.fromString((String)o[0])); 
      c.setRequest(((BigInteger)o[1]).longValue());

      c.setWorkflowRecords(findStatus(c.getIdCivilRecord())); 
      l.add(c); 
     } 
     return l; 
    } catch (Exception e) { 
     log.severe(e.getMessage()); 
     throw e; 
    } 
    }

對羅布森西爾維拉也有類似的迴應。

，請注意查詢字符串的最後一位。

public Account getAccount(String name, String password, String tenantId) { 
    Query q = em.createNativeQuery(
      "SELECT a.id, a.name, a.password, a.email FROM accounts a WHERE name = :name and password = :password and tenant_fk = CAST(:tenant_fk AS uuid)" 
    ); 
    q.setParameter("name", name); 
    q.setParameter("password", password); 
    q.setParameter("tenant_fk", tenantId); 

    List<Object[]> results = q.getResultList(); 
    if (results.size() == 0) { 
     return null; 
    } 

    return mapFromObject(results.get(0)); 
}
