如何顯示這些結果在一行在Oracle

Question

目前我有這三個表，該結構非常相似

table1:id1 name1 
table2:id2 name2 
table3:id3 name3 

我期望的結果將是

name1 name2 name3 
value1 value2 value3 

我嘗試使用聯合，在SQL是：

select name1 from table1 where id1 = '1' 
union select name2 from table2 where id2 = '2' 
union select name3 from table3 where id3 = '3' 

但結果證明是：

name1  
value1 
value2 
value3 

Answer 1

SELECT 
    (select name1 from table1 where id1 = '1'), 
    (select name2 from table2 where id2 = '2'), 
    (select name3 from table3 where id3 = '3') 
from dual; 

Answer 2

select name1,name2,name3 from table1,table2,table3 
where table1.id1=1 and table2.id2=2 and table3.id3=3;
