使用内部联接加入2个具有不同名称的表

Question

我有2个表首先是

之前

lotname     
--------    
R16A        
R17A        
R17B        
R18A        
R18B        

第二是

之后

lotname     
--------        
R16AA       
R17A        
R17B        
R18AAA      
R18B        

我想加入这两个表，以便像R16A匹配的所有内容都应与R16AA匹配

如果我写这段代码

select * from before
join after
    on before.lotname = after.lotname

O / P

lotname     lotname     
R17A        R17A        
R17B        R17B        
R18B        R18B        

我想要o / p喜欢

Lotname     Lotname     
----------------------------                
R16A        R16AA       
R17A        R17A        
R17B        R17B        
R18A        R18AAA      
R18B        R18B        

Answer 1

SELECT * FROM before
INNER JOIN after
ON after.lotname LIKE CONCAT(before.lotname,'%')
