Is there any way possible to get the desired output?

Answer 1

假设这是 SQLServer，请尝试：

; with 
c as (select codes, row_number() over (order by codes) r from codes),
e as (select email, row_number() over (order by email) r from email)
select codes, email
from c join e on c.r = e.r
order by c.r

Answer 2

你可以这样做。

select c.Codes , e.email
from CodesTable c, emailTable e
where c.rownum = e.rownum;

Answer 3

创建一个新表

创建表测试（代码varchar（32），电子邮件varchar（32）唯一（代码），唯一（电子邮件））；

执行这条sql的结果

选择'插入测试（代码，电子邮件）值（'''+代码+'''，'''+电子邮件+'''）;' 从 test1 ， test2

所有的sql都不会成功执行，但是表会按顺序填满
当你选择测试表时，你会得到你想要的

Answer 4

SELECT email, code
FROM 
(SELECT email, ROW_NUMBER() OVER(ORDER BY email) AS RowNum FROM email) AS T1
OUTER JOIN 
(SELECT code, ROW_NUMBER() OVER(ORDER BY code) AS RowNum FROM codes) AS T2
ON T2.RowNum = T1.RowNum
ORDER BY COALESCE(T1.RowNum, T2.RowNum)
