本文讨论了在使用Hibernate时遇到的问题，即从打印的SQL语句能够独立执行，但在程序中执行时出现错误。通过分析发现，问题在于自动映射实体时的不当操作。建议在不需要查询特定实体时，避免使用`.addEntity()`方法，并调整SQL语句以匹配实际需求。总结了如何正确处理此类情况，确保程序与SQL语句的无缝集成。

我将 Hibernate 打印出来的SQL 拿出来可以单独执行，但是 放到程序里就出错了。
最后找到问题根源
List pList = session.createSQLQuery(sql)
//.addEntity("d", DProviderToFactory.class)
.addEntity("m",MEnterprice.class)
.setFirstResult((page-1)*pageSize)
.setMaxResults(pageSize)
.list();
因为 我不需要 查询出 d 实体的内容 所以 就不用吧 d也实例化 将
//.addEntity("d", DProviderToFactory.class)
注释掉 就可以了。
如果不注释掉 也行 就修改sql 语句
StringBuffer sb = new StringBuffer();
sb.append(" select {m.*} ,{d.*} from d_provider_to_factory as d , m_enterprice as m where 1=1 ");
if ("0".equals(enterpriceType)) {
sb.append(" and d.provider_id = m.enterprice_id ");
}else if("1".equals(enterpriceType)){
sb.append(" and d.factory_id = m.enterprice_id ");
}
sb.append(" and m.flag_del = '0' ");
sb.append(" and d.flag_del = '0' ");
if ("0".equals(enterpriceType)) {
sb.append(" group by d.provider_id ");
}else if("1".equals(enterpriceType)){
sb.append(" group by d.factory_id ");
}
if (page <=0) {
page = 1;
}
String sql = sb.toString();
sb = null;
Session session = getSession();
List pList = session.createSQLQuery(sql)
.addEntity("d", DProviderToFactory.class)
.addEntity("m",MEnterprice.class)
.setFirstResult((page-1)*pageSize)
.setMaxResults(pageSize)
.list();
总结：如果非要用hibernate查询sql 语句并且进行自动映射的话，最好用到那个实体就添加那个实体。
