Mysql加入类似的列

Question

我想将table1与table2连接在'Name'列上,但table2.Name在所有名称前面都有一个'e'(如果table1.name = ABC,table2.name = eABC).我该如何使用这两个连接？我试过了FROM table1 join table2 on 'e'+table1.name = table2.name,但它不起作用......

Answer 1

SELECT  *
FROM    table1 t1
JOIN    table2 t2
ON      t2.name = CONCAT('e', t1.name)
