这是VICTIM_DETAILS表：
http://i.stack.imgur.com/1TEIK.png
这是COMPLAINT_DESCRIPTION表，
http://i.stack.imgur.com/qxvPN.png
我尝试过：我插入了以下声明
System.out.println(complaintID);
在调用getComplaintID（）方法之后，我在控制台上得到的输出与实际已经在表中的输出匹配（我已经交叉检查了它），这表明代码成功到达那里，这也表明getComplaintID（）方法成功执行。
另外，我在表单中没有留下任何值为null，并且所有值都是表格格式的约束。
答案 0 :(得分：7)
也许只是尝试调用没有参数的executeUpdate（）。您在创建PreparedStatement时已经设置了查询字符串。
ps.executeUpdate()
