SQL開發人員返回結果，而HQL返回錯誤

Question

我正在一個項目中，我必須生成一個HQL查詢以在JEE項目中完成任務。我的HQL查詢是：

requete.append("SELECT elec, MIN(tour.datScrutin) dat FROM HbEleElection elec, HbEleTourScrutin tour"); 
    requete.append(" WHERE elec.idEtaElection <> "+ cstRepository.getIdConstanteByLibelle("ETAT_ELECTION_TERMINEE")); 
    requete.append(" AND elec.id = tour.idElection"); 
    requete.append(" AND elec.zzzDsuEng is null"); 
    requete.append(" GROUP BY elec.lbcElection"); 
    requete.append(" ORDER BY dat "); 

但沒有得到任何結果。

我設法清理的東西，這是我的SQL開發人員的SQL查詢返回我想要的結果。

SELECT elec.lbc_election, 
    MIN(tour.dat_Scrutin) dat 
FROM Ele_Election elec, 
    Ele_Tour_Scrutin tour 
WHERE elec.id_Eta_Election <> 335 
    AND elec.id_election = tour.id_Election 
    AND elec.zzz_Dsu_Eng IS NULL 
GROUP BY elec.lbc_Election 
ORDER BY dat desc 

與我的HQL的java我得到這個錯誤的HQL：

1 net.sf.hibernate.QueryException：，預計將在選擇[選擇ELEC，MIN（tour.datScrutin）DAT FROM vdm.commun.scrutin.dao.hbbean.HbEleElection as elec，vdm.commun.scrutin.dao.hbbean.HbEleTourScrutin tour WHERE elec.idEtaElection <> 335 AND elec.id = tour.idElection AND elec.zzzDsuEng is null GROUP BY elec.lbcElection ORDER BY dat]

Answer 1

我想你錯過了'elec.lbc_election'並嘗試選擇Bean名稱，這就是爲什麼錯誤即將到來。請嘗試此查詢

requete.append("SELECT elec.lbc_election, MIN(tour.datScrutin) as dat FROM HbEleElection elec, HbEleTourScrutin tour"); requete.append(" WHERE elec.idEtaElection <> "+ cstRepository.getIdConstanteByLibelle("ETAT_ELECTION_TERMINEE")); requete.append(" AND elec.id = tour.idElection"); requete.append(" AND elec.zzzDsuEng is null"); requete.append(" GROUP BY elec.lbcElection"); requete.append(" ORDER BY dat ");
