Question

我是初学者，我只是自己学习，所以请原谅我是否能以程序员的方式表达我想说的话！我正在尝试开发可以执行此操作的简单业务应用程序：

注册员工或客户。

可以存储员工在支付工资之前可以提前支付的费用或金钱（这可以多次，或者可以   零）

可以存储付款（给予员工的工资） - 也可以多次付款

它可以计算所有费用，计算所有付款，然后找出它们的差额，因此将支付剩余的余额！

首先祝贺你尽可能地拥有。坏消息是t-sql不是一个报告工具 - 你需要寻找其他地方，如果你想要漂亮的输出（SSRS，Crystal报告，excel等等），你需要在t-sql中接近你所需的输出有点创意，例如： -
