Question

我在实现在这些行下定义的方法时遇到了一些问题，无法创建表并删除它。当我调试代码总是转到catch阻止但是创建和删除表的查询在postgreSQL控制台中执行时都能正常工作。知道为什么我有这些错误吗？或者使用Native Query进行这些操作有限制吗？

这里是源代码：

@Transactional(propagation = Propagation.REQUIRED)
      public int createTableTemporaireMesure(DashboardCriteriaBean criteria)
      {
          LOG.debug("début createTableTemporaireMesure");

          int retour = 0;

          // On supprime la table temporaire s'il existe
          dropTableTemporaireMesure();

          String queryString = "CREATE TABLE TMP_MESURE AS (select * from mesures mesure ";
          queryString += " where" + addMesureFilterOptimized(criteria).substring(4) + ")";

          LOG.debug("QueryString : " + queryString);
          Query query = em.createNativeQuery(queryString);

          try {
              query.getResultList();
        } catch (Exception e) {
            LOG.error("Error: " +e.getMessage());
            retour = 1;
        }

          LOG.debug("fin createTableTemporaireMesure");

          return retour;
      }

      @Transactional(propagation = Propagation.REQUIRED)
      public int dropTableTemporaireMesure()
    {
          LOG.debug("début dropTableTemporaireMesure");

          int retour = 0;

        String queryString = "DROP TABLE IF EXISTS TMP_MESURE";
        Query query = em.createNativeQuery(queryString);

        try {
            query.executeUpdate();
        } catch (Exception e) {
            StringBuilder sb = new StringBuilder("Erreur survenue lors de la suppresion de la table : ");
            sb.append("TMP_MESURES");
            sb.append(e.getMessage());
            LOG.error(e);
        }

        LOG.debug("fin dropTableTemporaireMesure");

        return retour;
    }
}

使用hibernate创建和删除表
