祝你好运 请注意，金钱永远不会加倍。这就是为什么十进制被发明的原因感谢ColinAlso，如果你没有唯一的键（有些人会说“primary”），那么你就没有真正的表。嗨，草莓，好建议我所有的表都有一个主键，id，但由于这只是一个测试，我只是试图将问题简化到最基本的程度，以复制这个问题。你对如何按代码、投资组合对结果进行分组以及如何按投资组合保持平衡有何想法，谢谢ColinHi webmite刚刚复制了你的代码和所有作品，我对结果非常满意，这正是我所需要的，祝你过得愉快，非常感谢你的帮助。问候科林坦克斯·科林。这是个好问题。你要找的东西足够清楚，并且你提供了一个数据样本。请记住将问题标记为已回答。别担心！
