JSP:Insert不起作用(SQLSERVER）
JSP: Insert not functioning (SQLSERVER)
您好。我是JSP的初学者，我把Daily Sales Monitoring作为一个项目。我已经做了研究，并制作了我的第一个CRUDjsp程序函数，但当我添加了很多列时，插入不起作用（删除和查看仍然有效）。没有可见的错误，但只要它在读取页面上重定向，就不会加载最新的数据。
我试着从各个角度查找错误，但似乎找不到。我试着计算所有列，重命名了一些实例，但它仍然无法工作。你能帮我解决我的问题吗？这是我第一次在这里提问，我似乎找不到前面问题的答案。感谢所有回复。
顺便说一下，我使用Netbeans IDE 8.1和Microsoft SQL Server

Shift:
<select name="shift">
<option value="World">GY</option>
<option value="World">AM</option>
<option value="Tech">PM</option>
</select><br><br>
我包含了选项值"World"answers"Tech"（这是我在互联网上找到的代码的一部分），即使数据库上"shift"列的定义是varchar（2）
很抱歉在琐碎的事情上耽误了你的时间。祝你今天过得愉快。
