java - 从MYSQL查询中的两个表中获取数据不起作用

Question

下面是两张表Vehicle和vehicle_owner

VEHICLE_OWNER 表

**Oid   Oname     Oage     Oaddress**                                
1     Ahsan     22       house 80/3 street no 22 rawalpindi 
2     Arslan    23       House no 56-C F6/2 Islamabad   

车辆表

**Vregno  Vname   Vmakername Vtype    Vyear       Vstatus      V_oid**
FSM393  Mehran  Suzuki     Car      2006        Clear          1
RLA3725 City    Honda      Car      2013        Stolen         2

代码：

PreparedStatement p = conn.prepareStatement("select Vstatus,Oname from Vehicle_Owner LEFT OUTER JOIN Vehicle ON vehicle_owner.Oid= Vehicle.V_oid where Vregno='"+ss+"'"); 
ResultSet r=p.executeQuery(); 
while(r.next()) { 
    vstatus=r.getString("Vstatus"); 
    oname=r.getString("Oname"); 
    System.out.println("Vehicle Status= "+vstatus+"<br>"); 
    System.out.println("Owner name= "+oname+"<br>");
}

我想根据车辆注册号显示 Oname 和 Vstatus。(Vregno) 我正在使用这个查询，但它在 MYSQL 中不起作用

select Vstatus,Oname from Vehicle_Owner INNER JOIN Vehicle ON vehicle.V_oid= vehicle_owner.Oid AND Vregno="FSM393";

任何人请帮助我
