Question

String s1 = Fname.getText();
String s2 = Lname.getText();
String s3 = usr.getText();
String s4 = psswd.getText();
String s5 = Eml.getText();
String s6 = sx.getText();
String s7 = DOB.getText();
String s8 = mob.getText();
String s9 = city.getText();

if((s3 != null) && (s4 != null))
    try
    {
        String query = "INSERT INTO SIGNUP " + "(F_NAME varchar2(10), L_NAME varchar2(10), USER_ID varchar2(10), PASSWD varchar2(15), E_MAIL varchar2(30), SEX varchar2(7), DOB Date, MOB_NO varchar2(10), CITY varchar2(15))" + " VALUES(?,?,?,?,?,?,?,?,?)";
        String user = "system";
        String psswd = "sys123";
        String url = "jdbc:oracle:thin:@localhost:1521:xe";
        Class.forName("oracle.jdbc.driver.OracleDriver");
        connection = DriverManager.getConnection(url, user , psswd);
        //System.out.println(query);

        preparedStatement = connection.prepareStatement(query);
        preparedStatement.setString(1, s1);
        preparedStatement.setString(2, s2);
        preparedStatement.setString(3, s3);
        preparedStatement.setString(4, s4);
        preparedStatement.setString(5, s5);
        preparedStatement.setString(6, s6);
        preparedStatement.setString(7, s7);
        preparedStatement.setString(8, s8);
        preparedStatement.setString(9, s9);
        int temp = preparedStatement.executeUpdate();

        if (temp > 0)
        {
            String msg = "Congratulations! Registration Successful...";
            JOptionPane.showMessageDialog(b1, null, msg, temp);
        }
    }
    catch (Exception e) {
        // TODO: handle exception
        System.out.println(e.getMessage());
        e.printStackTrace();
    }

嗯，我知道这是一个重复的问题并且已被多次询问过。但是，我仍然无法修复它。我检查过每个可能的错误，如空格，单引号，但它仍然无法正常工作。 UserID和Password字段不可为空。

Answer 1

从INSERT中删除类型定义varchar2(10)等。

"INSERT INTO SIGNUP " + "(F_NAME, L_NAME, USER_ID ...)"

Answer 2

String query = "INSERT INTO SIGNUP " + "(F_NAME , L_NAME , USER_ID , PASSWD , E_MAIL, SEX , DOB Date, MOB_NO , CITY )" + " VALUES(?,?,?,?,?,?,?,?,?)";

我建议这是一种更好的方法。如果您使用的是Java，为什么不使用Entity JPA 2.2。它将管理您的CRUD操作。
