Question

我编写了一个程序，用一个单词列表填充数据库。问题是，它每次我尝试运行代码时都会抛出“线程中的异常”主“java.sql.SQLException：near”。“：语法错误”。我转向你寻求帮助。

这是代码

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.Random;
import javax.swing.JOptionPane;
import javax.swing.JTextField;

以下是来源：

public Account() {
            super("Create Account");
            initComponents();
            conn=javaconnect.ConnecrDb();
            RandomAcc();
            RandomMICR();
            RandomPIN();
        }

    public void RandomAcc(){
        Random ra=new Random();
        jTextField1.setText(""+ra.nextInt(10000+1));
    }
    public void RandomMICR(){
        Random ra=new Random();
        jTextField2.setText(""+ra.nextInt(1000+1));
    }
    public void RandomPIN(){
        Random ra=new Random();
        jTextField3.setText(""+ra.nextInt(1000+1));
    }
    public void Bal(){
        String sql="insert into Balances(Name,Acc,MICR_No,Balance) values(?,?,?,?)";
        try{
        pst=conn.prepareStatement(sql);
        pst.setString(1, jTextField5.getText());
        pst.setString(2, jTextField1.getText());
        pst.setString(3, jTextField2.getText());
        pst.setString(4, jTextField10.getText());
        pst.execute();   
    }catch(Exception e){`enter code here`
        JOptionPane.showMessageDialog(null, e);
    }
 }

String sql="insert into Account(Acc,Name,DOB,Pin,Acc_Type,Nationality,Caste,MICR_No,Gender,Mob,Address,Sec.Q,Sec.A,Balance) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
    try{
        pst=conn.prepareStatement(sql);
        pst.setString(1, jTextField1.getText());
        pst.setString(2, jTextField5.getText());
        pst.setString(3,((JTextField)jDateChooser1.getDateEditor().getUiComponent()).getText());
        pst.setString(4, jTextField3.getText());
        pst.setString(5, (String) jComboBox1.getSelectedItem());
        pst.setString(6, (String) jComboBox2.getSelectedItem());
        pst.setString(7, jTextField6.getText());
        pst.setString(8, jTextField2.getText());

        jRadioButton1.setActionCommand("Male");
        jRadioButton2.setActionCommand("Female");
        pst.setString(9, buttonGroup1.getSelection().getActionCommand()); 

        pst.setString(10, jTextField7.getText());
        pst.setString(11, jTextField4.getText());
        pst.setString(12, (String) jComboBox3.getSelectedItem());
        pst.setString(13, jTextField9.getText());
        pst.setString(14, jTextField10.getText());
        pst.execute();
        JOptionPane.showMessageDialog(null, "Congrtz\n Account has been Created");
        Bal();
    }catch(Exception e){
        JOptionPane.showMessageDialog(null, e);
    }
}

Answer 1

String sql="insert into Account(Acc,Name,DOB,Pin,Acc_Type,Nationality,Caste,MICR_No,Gender,Mob,Address,Sec.Q,Sec.A,Balance) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

Sec.Q,Sec.A列名称是？这是不允许的。

java.sql.SQLException：near“。”：语法错误
