困惑

        StringBuffer recordSql = new StringBuffer(200);
        
        recordSql.append(" update DeviceAlarmOperateInfo a set a.description = :msg where 1 = 1 ");
        
        if (orgCode != null && !"".endsWith(orgCode)) {
            recordSql.append(" and a.deviceinfo.organization.orgzCode like :orgCode ");
        }
        
        recordSql.append(" and a.modifiedUser = null ");

        recordSql.append(" and a.currentstatus <> 0 ");

        recordSql.append(" and a.operatetime >= :startDate ");

        recordSql.append(" and a.operatetime < :endDate ");

        Query recordQuery = em.createQuery(recordSql.toString());
        
        recordQuery.setParameter("msg", msg);
        
        if (orgCode != null && !"".endsWith(orgCode)) {

        }

        recordQuery.setParameter("startDate", starttime);
        recordQuery.setParameter("endDate",  DateUtil.getStartDate(endtime, 1));
        
        int count = recordQuery.executeUpdate();
        return count;

报错：

javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute statement

SQL Error: 1064, SQLState: 42000

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'set description='confirmed by app' where 1=1 and (orgz_code like '10021007%') an' at line 1

sql执行都是成功的

SELECT a.* from tip_s_DeviceAlarmOperateInfo a LEFT JOIN tip_s_systemdeviceinfo d on d.id = a.Device_id left JOIN s_organization o on o.id = d.organization_id where 1=1 and o.orgz_code like '10021007%'

update tip_s_DeviceAlarmOperateInfo a LEFT JOIN tip_s_systemdeviceinfo d on d.id = a.Device_id left JOIN s_organization o on o.id = d.organization_id set a.description='aaa' where 1=1 and o.orgz_code like '10021007%'

去掉关联表的字段匹配后，是可以执行的

        StringBuffer recordSql = new StringBuffer(200);
        
        recordSql.append(" update DeviceAlarmOperateInfo a set a.description = :msg where 1 = 1 ");
        
        recordSql.append(" and a.modifiedUser = null ");

        recordSql.append(" and a.currentstatus <> 0 ");

        recordSql.append(" and a.operatetime >= :startDate ");

        recordSql.append(" and a.operatetime < :endDate ");

        Query recordQuery = em.createQuery(recordSql.toString());
        
        recordQuery.setParameter("msg", msg);

        recordQuery.setParameter("startDate", starttime);
        recordQuery.setParameter("endDate",  DateUtil.getStartDate(endtime, 1));
        
        int count = recordQuery.executeUpdate();
        return count;
