我已经在这里工作了大约3个星期，并且已经阅读并观看了YouTube中的很多视频，我跟着它去了T但是没有一个适合我。此时我正在拔毛。
网站在网页浏览器中显示正常，但是当文本框被填满并且提交按钮被命中时数据库保持空白。
所以这就是我所拥有的：

答案 0 :(得分：4)
INSERT INTO 3DayTrial(RefferalName, ReferralCodeValues(@First_Name, @Middle_Name, @Last_Name, @Email, @Phone, @GTTR, @GDTR, @Issues)
这对我来说看起来不像是有效的SQL。插入语句通常具有
之一所以我希望你的SQL看起来像这样：
INSERT INTO 3DayTrial
VALUES (@First_Name, @Middle_Name, @Last_Name, @Email, @Phone, @GTTR, @GDTR, @Issues)
或
INSERT INTO 3DayTrial
SELECT @First_Name, @Middle_Name, @Last_Name, @Email, @Phone, @GTTR, @GDTR, @Issues
您可能还需要一个字段列表 - 但我们无法知道，因为您没有向我们展示非常重要的信息。表名和表创建语句 - 要真正理解发生了什么，我们也需要看到它。
考虑一些错误检查。这条线
xp.ExecuteNonQuery();
应该是
int count = xp.ExecuteNonQuery();
if (count != 1)
{
// handle insert error
}
如果您正在调用返回值的函数，我建议您始终检查返回值。不会有任何伤害，你会编写更好的代码。
答案 1 :(得分：1)
您没有为按钮定义点击方法。按照编码，此按钮除了导致回发之外不会执行任何操作。 Submit_Click方法将不会执行。您需要阅读并了解调试中的断点。如果您已经完成了代码，那么您会发现您的方法永远不会触发。
您需要在按钮代码中添加onclick="Submit_Click"。
然后您很快就会发现Hogan提供的答案将解决点击事件发生时遇到的问题。
