我有一个表CleintParentQuestion，它有一个列qid。
+------+
| qid |
+------+
| 1 |
| 2 |
| 3 |
| 4 |
+------+
我想删除qid不是1还是2的所有细节
所以sql查询是
DELETE FROM client_parent_question WHERE qid<> 1 AND qid <>2
但是当我尝试使用jpa
执行时@Transactional
public void deleteFromClientParentQuestion(String qids) {
String queryString=" DELETE FROM client_parent_question WHERE "+qids;
System.out.println("deleteFromClientParentQuestion "+queryString);
int delete=entityManagerUtil.getEntityManager().createQuery(queryString).executeUpdate();
}
给我错误
org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.hql.ast.QuerySyntaxException: client_parent_question is not mapped [ DELETE FROM client_parent_question WHERE qid<> 1]; nested exception is java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: client_parent_question is not mapped [ DELETE FROM client_parent_question WHERE qid<> 1]] with root cause

注意 qids将返回qid<> 1 AND qid<> 2
因此queryString变为DELETE FROM client_parent_question WHERE qid<> 1 AND qid<> 2
答案 0 :(得分：0)
您正在尝试将SQL查询作为HQL查询执行。
getEntityManager().createQuery(queryString)
这是用于创建HQL查询而不是SQL查询。对于sql，您必须使用createNativeQuery
getEntityManager().createNativeQuery(queryString)
答案 1 :(得分：-1)
更改您的查询
DELETE FROM client_parent_question WHERE qid ="+qids
