选择仅在mysql中的特定列

Question

我的表1有20列，而表2有15列。在这里我想通过用户ID连接两个表。我用这个波纹管查询

SELECT  * FROM   table_checkout_bidpack as t1 inner JOIN table_user_information 
as t2 ON t1.user_id=t2.user_id

该查询选择35列，但我需要在第二张表的column（user_name）上进行选择

我知道这工作

select t1.col1,t1.col2,t1.col3,t1.col4,.....,t2.user_name 
FROM   table_checkout_bidpack as t1 inner JOIN table_user_information 
as t2 ON t1.user_id=t2.user_id

这看起来很其他方法

Answer 1

select t1.*,t2.user_name 
FROM   table_checkout_bidpack as t1 inner JOIN table_user_information 
as t2 ON t1.user_id=t2.user_id
