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

Question

我正在從一個表中獲取數據並想要插入到其他表中。 第一個包含很多字段的表，如果要存儲在新表中，我只需要一些字段。爲此，我使用Hibernate查詢。 我能夠從查詢獲取結果，但是當我嘗試插入到其他表扔

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

下面是拋出異常的代碼。

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()); 

當我運行下面的代碼而不使用query.executeUpdate（）;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(); 

出把上面的代碼是 命令執行成功.... NUMER的影響記錄...，21。

如果你正在做的插入或更新，你應該只調用

query.executeUpdate(); 

，而不是

query.list(); 

嘗試像這樣（你缺少的選擇部分的別名，所以Hibernate是困惑subs_id）：

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());
