Question

我无法弄清楚这一点，并在10小时内到期。如果有人怜惜请帮助。

基本上我试图在名为Appointments的访问表中插入数据。但是每次我都会收到不正确的sql语法错误。我已经浏览了很多sql的例子，这似乎是正确的，我无法解决这个问题。代码和堆栈跟踪如下。错误行表示为第27行或statement.executeupdate（）行。我试图在JSP中执行此操作。

<%
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
java.sql.Connection connection = java.sql.DriverManager.getConnection("jdbc:odbc:Dentist", "", "");

String query = "INSERT INTO Appointments(First_Name, Last_Name, Address, Phone_Number, Procedure, Appointment_Date, Health_Insurance, Health_Concerns, Age, Emergency_Contact, Cost) VALUES(?,?,?,?,?,?,?,?,?,?,?)";
java.sql.PreparedStatement statement = connection.prepareStatement(query);

statement.setString(1, request.getParameter("First_name"));
statement.setString(2, request.getParameter("Last_Name"));
statement.setString(3, request.getParameter("Address"));
statement.setString(4, request.getParameter("PhoneNumber"));
statement.setString(5, request.getParameter("Procedure"));
statement.setString(6, request.getParameter("Appointment_Date"));
statement.setString(7, request.getParameter("Health_Insurance"));
statement.setString(8, request.getParameter("Health_Concerns"));
statement.setString(9, request.getParameter("Age"));
statement.setString(10, request.getParameter("Emergency_Contact"));
statement.setString(11, request.getParameter("Cost"));

statement.executeUpdate(query);
connection.close();
response.sendRedirect("ShowData.jsp");
%>

Answer 1

已为PreparedStatement定义了查询。取代

statement.executeUpdate(query);

带

statement.executeUpdate();

准备好的SQL语句无效
