在插入SQL语句时出错

Question

我试图将用户输入的数据插入数据库，但得到错误“Syntax error：Encountered”[“at line 1，column 160。”这里是我的代码，我究竟做错了什么？'

if (action.getSource() == Submit_button) 
{ 
    try 
    { 
     sql = "INSERT INTO Customer (FNAME, LNAME, AGE, LICNUM, STATE, CAR_TYPE, RENTDATE, RETURNDATE, TOTAL, PAYTYPE, RETURNED) VALUES("; 
     sql = sql + "'" + f_name.getText() + "'" + "," + "'" + l_name.getText() + "'" + "," + Age + "," + "'" + liscense_num.getText() + "'" + "," + "'" 
      + issuing.getText() + "'" + "," + "'" + car_select.getToolkit() + "'" + "," + "'" + rental.getText() + "'" + "," + "'" + return_d.getText() + "'" 
      + "," + total.getText() + "," + "'" + button_val.getText() + "'" + "," + "'true'" + ")"; 
     myStatement.execute(sql); 
     System.out.print("Record has Been added to database"); 
    } 
    catch (SQLException e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
}

您可以更改查询到这一点？

sql = "INSERT INTO Customer (FNAME, LNAME, AGE, LICNUM, STATE, CAR_TYPE, RENTDATE, RETURNDATE, TOTAL, PAYTYPE, RETURNED) VALUES('"+f_name.getText()+"','"+l_name.getText()+"','"+Age+"','"+liscense_num.getText()+"','"+issuing.getText()+"','"+car_select.getToolkit()+"','"+rental.getText()+"','"+return_d.getText()+"','"+total.getText()+"','"+button_val.getText()+"','true') ";
