'程序或函数 insert_newemployee 指定的参数太多。'

Question

我有一个新员工注册页面，用于在此注册新员工

这是我将值传递给存储过程的地方

protected void btnbutton_Click(object sender, EventArgs e)
    {
        try
        {

            upload_photo();
            uploadfile();

我已经检查了很多次，这两个值都是一样的。

Answer 1

查询有 37 个参数，提供了 38 个参数。我的猜测是，如果它最初是有效的，那么有人已经改变了程序。 每当我收到此错误时（由于在许多不同的应用程序中使用 SP 并且许多不同的人更改它们而经常发生），我将参数从代码和 sql 复制到 notepad++ 并进行比较。
