出现这个需求的原因是因为项目里面有个订单迁移工程，某一天的有些订单没有迁移到历史表里面去，然后现在要我将这些订单重新迁移到历史表中，
先写一个简单的例子，比如说我现在B表中的数据，要迁移到A表中，
可以直接这么写，
insert into A(字段1，字段2，字段3......) select 字段1，字段2，字段3.... from B
注意字段一定要对上，不然到时订单字段迁移错误就尴尬了，写完后，你可能会报个“ORA-00913: 值过多”的错误，不要担心，是你字段写错误了，一个一个重新对比一下，
再举个“栗子”,
如果现在要将B表和C表的数据都迁移到A表中
insert into A(字段1，字段2，字段3，字段4) select b.字段1，b.字段2,c.字段3,c.字段4 from B b,C c where b.某字段=c.某字段
废话不多说了，我就把我的sql拿上来了
