我正在使用Java和MySQL开发员工薪资管理系统。当我尝试添加记录时,就会发生此错误。
我的代码在这里:
try {
String sql ="insert into Staff_information "
+ "(first_name,surname,Dob,Email,"
+ "Telephone,Address,Department,"
+ "Image,Salary,Gender,Address2,"
+ "Post_code, Designation,Status,job_title,Apartment,Date_hired) values (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?) ";
pst=conn.prepareStatement(sql);
pst.setString(1,txt_firstname.getText());
pst.setString(2,txt_surname.getText());
pst.setString(3,txt_dob.getText());
pst.setString(4,txt_email.getText());
pst.setString(5,txt_tel.getText());
pst.setString(6,txt_address.getText());
pst.setString(7,txt_dep.getText());
pst.setBytes(8,person_image);
pst.setString(9,txt_salary.getText());
pst.setString(10,gender);
pst.setString(11,txt_add2.getText());
pst.setString(12,txt_pc.getText());
pst.setString(13,txt_design.getText());
pst.setString(14,txt_status.getText());
pst.setString(15,txt_job.getText());
pst.setString(16,txt_apt.getText());
pst.setString(17,txt_doj.getText());
pst.execute();
JOptionPane.showMessageDialog(null,"Data is saved successfully");
} catch (Exception e) {
JOptionPane.showMessageDialog(null,e);
} finally{
try {
rs.close();
pst.close();
} catch(Exception e) {
JOptionPane.showMessageDialog(null,e);
}
}
}
最佳答案
您的表还具有一个非空列id
(可能是主键),没有默认值。这意味着您必须在查询中分配一个值。
这也可能意味着您打算将其作为标识列(AUTO_INCREMENT
),但是忘记将其设置为1。
