我不明白问题出在哪里，因为以下查询是按照 MYSQL Workbench 中的要求执行的。
下面是我在 JPA 中的 NativeQuery 函数
public ConsumerAggregatedDTO getCustomerEnrolled(Long businessAccountId, String paramName, String screenName,String status) {
ConsumerAggregatedDTO consumersEnrolled = null;
try {
String query = "select count(distinct consumer_id) from Consumer_Business_Acct_Mapping t1 join "
+ "Dim_Date t2 on date(t1.created_date)=t2.full_date where t1.business_acct_id= :business_account_id and t1.status= :status and t2.full_date between"
+ "(select str_to_date(lower_bound,'%Y-%m-%d') from Param_App where business_account_id= :business_account_id and screen_name= :screen_name and param_name= :param_name and status= :status) "
+ "and (select str_to_date(upper_bound,'%Y-%m-%d') from Param_App where business_account_id= :business_account_id and screen_name= :screen_name and param_name= :param_name and status= :status)";
consumersEnrolled = (ConsumerAggregatedDTO) entityManager.createNativeQuery(query, ConsumerBusinessAccount.class)
.setParameter("business_account_id", businessAccountId)
.setParameter("param_name", paramName)
.setParameter("screen_name",screenName)
.setParameter("status", status)
.getSingleResult();
}
// catch(EmptyResultDataAccessException ex)
catch (javax.persistence.NoResultException ex) {
// No entity found for query
return null;
}
return consumersEnrolled;
}
当运行代码时，它会收到错误列“id”未找到并抛出 Java SQLException。 下面是 stackTrace。
java.sql.SQLException: Column 'id' not found.

我无法理解问题到底出在哪里。如果有人可以显示错误或我犯错误的方法。
最佳答案
您的查询返回一个 COUNT(*)，但您告诉 JPA 将其映射到 ConsumerAggreatedDTO 对象。
而不是
consumersEnrolled = (ConsumerAggregatedDTO) entityManager.createNativeQuery(query, ConsumerBusinessAccount.class)
使用
BigInteger count = (BigInteger)entityManager.createNativeQuery(query)
并使用结果值手动创建 ConsumerAggreatedDTO 对象。
关于java - JPA/Hibernate native 查询未按要求工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41743288/
