加入不相關的表

Question

我想加入這兩個不相關的表：

表1

id name age 
-- ---- --- 
1 a  9 
2 b  11 
3 c  10 

表2

id school address 
-- ------ ------- 
1 aa  abc 
1 aa  efg 
3 bb  hij 

期望的結果：

id school address age name 
-- ------ ------- --- ---- 
1 aa  abc  9  a 
1 aa  efg  9  a 
2 NULL  NULL  11 b 
3 bb  hij  10 c 

Answer 1

SELECT t1.id, t2.school, t2.address, t1.age, t1.name 
FROM dbo.table1 AS t1 
LEFT OUTER JOIN dbo.table2 AS t2 
ON t1.id = t2.id 
ORDER BY t1.id;
