如何在SQL Server中为数值插入文字中的数字？

我想为SQL Server编辑此代码

例如，当我输入2500美元价格时，它应该自动插入到下一个字段中，仅为2500美元。此外，当我输入100.35时，它会自动插入其他字段，仅为一百美元三十五美分

CREATE FUNCTION [dbo].[Currency_ToWords] (
    @Input Numeric (38) -- Input number with as many as 18 digits

) RETURNS VARCHAR(8000)

我需要触发代码来自动调用这个函数

谢谢

我们不为您编写代码。向我们展示您的尝试。是否可以在sql server指南中进行说明。谢谢。@gotqn所以，你把答案带到那里，并在上面建立。对于这个问题的每一种可能的变化，我们不需要一个新的解决方案。@gotqn我不同意。有些工作不应该在OP上吗？毕竟，问题出在他们身上。我不认为每次有人在这方面发明了一些变体，一群人就应该开始做与复制品几乎完全相同的事情的全新答案。这就是我们有重复的全部原因：为了避免重复回答者的工作。@gotqn我认为你的解释太字面了。我的意思是，如果有人问了完全相同的问题，但有一个额外的逗号，或其他空格，或任何东西，它将不会是一个确切的副本，但它仍然是一个重复。在这种情况下，这个问题显然是重复的，只需要做一点工作，他想把数值100.50转换成字符串“一百美元五十美分”。我不这么认为。哦，好吧，我想op只需要2500美元或50.15美元的整数值：这一切都是徒劳的，我应该删除它吗？
