Question

我在 hibernate 中有以下查询：

 session.createQuery("FROM RegionFile T1 WHERE (T1.action = 'MODIFY' or T1.action = 'CREATE' or (T1.action = 'NONE' " +
                        "AND T1.docid NOT IN (SELECT T2.docid FROM RegionFile T2 WHERE T2.action in ( 'MODIFY','DELETE')))) " +
                       "AND T1.rgndoc like '%" + dgId + "%'")

但是，我收到以下错误：

查询语法异常

我在这里做错了什么？

Answer 1

I tried in MySql database and it successfully execute have used below query...please try again and check carefully spaces. 

Query query = session.createQuery("FROM Region T1 WHERE (T1.action = 'MOD' or T1.action = 'CRT' or (T1.action = 'NON' " +
                            "AND T1.id NOT IN (SELECT T2.id FROM Region T2 WHERE T2.action in ( 'MOD','DEL')))) " +
                           "AND T1.rgndoc like '%" + dgId + "%'");          
            List<Region> list = query.list();
            Iterator<Region> itr = list.iterator();
            System.out.println("before calling");
            while(itr.hasNext())
              System.out.println(itr.next().getAction());

我想通过关注你的问题来建议。

createQuery（“FROM RegionFile T1 WHERE（T1.action ='MODIFY'或T1.action ='CREATE'或（T1.action ='NONE'”+“AND T1.docid NOT IN（SELECT T2.docid FROM） RegionFile T2 WHERE T2.action in（'MODIFY'，'DELETE'）））“+”AND T1.rgndoc like'％“+ a +”％'）“）

任何人都可以在hibernate查询中找到错误吗？
