Question

我正在从一个表中获取数据并希望插入到其他表中。第一个表包含许多字段，如果要存储在新表中，我只需要一些字段。为此，我正在使用Hibernate查询。我能够从查询中获取结果，但是当我尝试插入其他表时，它会抛出

org.hibernate.hql.internal.QueryExecutionRequestException：DML操作不支持[insert into

以下是抛出异常的代码。

Query query=session.createQuery(" insert into CustomerMailAddress (subs_id,mail_Id) SELECT DISTINCT  subs_id, email_id FROM SubcriberModel WHERE subs_id IS NOT NULL AND email_id IS NOT NULL AND email_id <> ''");
List result = query.list();
int res = query.executeUpdate();
System.out.println("Command successfully executed....");
System.out.println("Numer of records effected...,"+result.size());

当我在不使用query.executeUpdate（）的情况下运行代码时;方法

Query query=session.createQuery(" SELECT DISTINCT  subs_id, email_id FROM SubcriberModel WHERE subs_id IS NOT NULL AND email_id IS NOT NULL AND email_id <> ''  UNION ALL SELECT DISTINCT tbl_subscribers_subs_id, email_id FROM SocialProfileModel WHERE tbl_subscribers_subs_id IS NOT NULL AND email_id IS NOT NULL AND email_id <> ''");
List result = query.list();

以上代码的输出是命令成功执行.... 记录的数量影响...，21。

如果您正在进行插入或更新，则只应致电

query.executeUpdate();

而不是

query.list();

尝试这样（你在选择部分中缺少别名，因此Hibernate对subs_id感到困惑）：

Query query=session.createQuery("insert into CustomerMailAddress (subs_id, mail_Id)"+"SELECT DISTINCT m.subs_id, m.email_id FROM SubcriberModel m WHERE m.subs_id IS NOT NULL AND m.email_id IS NOT NULL AND m.email_id <> ''");
int res = query.executeUpdate();
System.out.println("Command successfully executed....");
System.out.println("Numer of records effected...,"+result.size());

org.hibernate.hql.internal.QueryExecutionRequestException：DML操作不支持[插入到
