您应该使用这个视图。 –

我可否知道你为什么要把它存放到第三张桌子？ – Demonyowh

@LuudvanKeulen为什么？ – Strawberry

有两种表作为提以上当我们运行代码

Create table tablc as 
select name,n1,n2,color,State,' ' as sname FROM tablea 
union 
select '' as name,n3,n4,'' as color ,'' as State ,'s.name' as sname from tableb

新表将创建enter image description here

输出将显示为表tablc

SELECT结果，你可以使用简单的union all：

select Name as Name, N1 as N1, N2 as N2, Color as Color, State as State, null as S_Name from tableA 
union all 
select null as Name, N3 as N1, N4 as N2, null as Color, null as State, S_Name as S_Name from tableB

我跑了查询，但我可以看到数据库，但是当我刷新表时，数据消失......不知道发生了什么？ –

@ShahidShabbir - 这只是'select'查询，这不存储结果无处。你需要将结果存储到另一个表中？ –

谢谢，我想通了，这是一个需要插入语句。谢谢 –

你可以通过工会叫它什么都

select name, n1, n2, color, state, null as 's_name' as recordtype from tablea 
union all 
select null as 'name', n3 as 'n1', n4 as 'n2', null as 'color', null as 
'state', s_name from tableb
