将数据插入oracle sql live

我正在尝试将数据插入到我在Oracle SQL live上创建的表中。我可以一次输入一行数据，但当我尝试同时输入所有数据时，会收到一条错误消息，表明SQL命令未正确结束。我使用下面的代码。我不知道我做错了什么：

Insert into PET_OWNER (OwnerID, OwnerLastName , OwnerFirstName , OwnerPhone , OwnerEmail) 
Values (1, 'Downs' , 'Marsha' , '555-537-8765' , 'Marsha.downs@somewhere.com'), 
Values (2 , 'James' , 'Richard' , '555-537-7654' , 'Richard.James@somewhere.com'),  
Values (3 , 'Frier' , 'Liz' , '555-537-6543' , 'Liz.Frier@somewhere.com'),  
Values (4 , 'Trent' , 'Miles' , 'Miles.Trent@somewhere.com');  

试试下面这样

    Insert into PET_OWNER (OwnerID, OwnerLastName , OwnerFirstName , OwnerPhone , OwnerEmail) 
    select 1, 'Downs' , 'Marsha' , 
    '555-537-8765' , 'Marsha.downs@somewhere.com' from dual
    union all
    select 2 , 'James' , 'Richard' , 
    '555-537-7654' , 'Richard.James@somewhere.com' from dual
    union all
    select 3 , 'Frier' , 'Liz' ,
   '555-537-6543', 'Liz.Frier@somewhere.com' from dual
    union all
    select 4 , 'Trent' , 'Miles' , 
    null,'Miles.Trent@somewhere.com'  from dual
