如何在一个表中合并具有差异列名的多个表？

我有表1和表2，所以我想将table2的字段合并到table1中。

例如：

表1

ID NAME
1  A
2  B
3  C

表2

SEX Address
M   A
F   B
M   C

我需要的结果如下：

结果

ID NAME SEX  ADDRESS
1  A    M    A
2  B    F    B
3  C    M    C

如何在mysql中执行此操作？

Answer 1

做这样的事情：

SELECT t1.ID, t1.NAME, t2.SEX, t2.ADDRESS from table1 t1 cross join table2 t2;

或

SELECT t1.ID, t1.NAME, t2.SEX, t2.ADDRESS from table1 t1, table2 t2;

Answer 2

<强> Here is the SQLFiddel working Demo

以下是您可以尝试的查询

select T1.ID,T1.Name,T2.Sex,T2.Address
  from 
(select *,@Row1 := @Row1 + 1 as rownum
  from Table1
  join (select @Row1 := 0) r) as T1
join
(select *,@Row2 := @Row2 + 1 as rownum
  from Table2
  join (select @Row2 := 0) r) as T2
Where T1.rownum = T2.rownum
