Question

我有以下更新查询，但在查询中找不到错误

 public void updateContact(contact cont){
    
     Connection con=myConnection.getConnection();
    PreparedStatement ps ;
    try {
        // below is Query Check full line 
   String updateQuery=" UPDATE `mycontact` SET `firstName`=?,`lastName`=?,`group`=?,`phone`=?,`email`=?,`address`=?, WHERE `id`=?";

       ps=con.prepareStatement(updateQuery);
       ps.setString(1, cont.getFirstName());
       ps.setString(2, cont.getLastName());
       ps.setString(3, cont.getGroup());
       ps.setString(4, cont.getPhone());
       ps.setString(5, cont.getEmail());
       ps.setString(6,cont.getAddress() );
       ps.setInt(7, cont.getCid());
     
       if(ps.executeUpdate() !=0){
               JOptionPane.showMessageDialog(null, "contact Data Edited ");
           }else{
                       JOptionPane.showMessageDialog(null, "Somthing Wrong");

               }       
       
    } catch (SQLException ex) {
        System.out.println("err in  update query");
        Logger.getLogger(contactQuery.class.getName()).log(Level.SEVERE, null, ex);
    }

}

Front.contactQuery updateContact

SEVERE: null

Answer 1

删除地址后面的逗号:

`address`=?,

SQL 无法忽略末尾的额外逗号。因此，在复制粘贴编辑 SQL 文本时要小心。
