    @fhefh 有三种方法。都写伪代码。
    第一种是 insert into table select * from table1
    第二张是 insert into a from table a insert into table2 b
    第三张在 sql server 的: select * into table from table2
    第二种用得多一些。上面写这么多是因为有一个 ordersm 和 orderno 可以连起所有的表。然后要什么数据去什么表去取。

    有很多很多人在写代码的时候有很惰性的心理,总想在一个地方把事情处理了,所以就会出现把很复杂的操作扔到 SQL 中。

    写这样的 SQL 不难,特别是很多刚入行的人,经常就会写出这样的,你要是一点一点读的话,会发现它就是把各种判断和运算放进去而已,就像平铺直叙的作文一样。

    这样的结果会给自己挖个很大很大的坑,如果逻辑发生变化了,变动会非常困难。

    而且更可怕的是过于依赖写死的内容,甚至传说中的 magic number ,一旦出现未知的数据很可能就崩了。。。
