加入SQL结果

Question

请帮我加入命令的结果（MS SQL）：

SELECT name,value FROM table1 WHERE idfoo1 IN(SELECT _id FROM table3 where id = 1); 
SELECT value FROM table2 WHERE idfoo2 IN(SELECT _id_2 FROM table3 where id = 1) AND name='fooname'; 

我也得到：

name value 
John 2  
Bill 32  
Alex 11 

value 
434 
234 
144 

但我需要加入的结果。 ！

name value value 
John 2  434 
Bill 32 234 
Alex 11 144 

所以，ID == ID，_id = _id_2，

Answer 1

使用此查询：

SELECT t1.name, 
     t1.value, 
     t2.value 
FROM table1 t1 
INNER JOIN table3 t3 ON t1.idfoo1 = t3._id 
INNER JOIN table2 t2 ON t2.idfoo2 = t3._id_2 
WHERE t3.id=1 AND t2.name = 'fooname' 

Answer 2

Select a.name,a.value,c.value FROM table1 as a inner join table3 as b 
on a.idfoo1=b.id and b.id=1 inner join table3 as c 
on c.idfoo2=b._id_2 and b.id=1 and c.name='fooname' 

Answer 3

我想这就是你需要 -

SELECT t1.name, t1.value, t2.value 
FROM table1 t1, table2 t2, table3 t3 
WHERE 
    t1.idfoo1 = t3._id 
    AND t2.idfoo2 = t3._id_2 
    AND t3.id = 1 
    AND t2.name='fooname';
