                    cmd = new MySqlCommand();
                    cmd.CommandText = "update emppassdetails set activepass='" + label19.Text + "'";
                    cmd.Connection = con;
                    cmd.ExecuteNonQuery();

                }
                else if (ppass > 0 && checkBox5.Checked == false)
                {
                    c = ppass - b;
                    label19.Text = c.ToString();
                    cmd = new MySqlCommand();
                    cmd.CommandText = "update emppassdetails set activepass='" + label19.Text + "'";
                    cmd.Connection = con;
                    cmd.ExecuteNonQuery();

                }
            
            }
            catch (Exception ex)
            {
                MessageBox.Show("Please Call Anurag"+ex.Message );
            }
        }

Here PPASS IS declared globally and other variables are local but elseif statement is giving error and if statement is working fine

hi friend you should read this,

The problem is that those empty values are interpeted as empty strings (''), not as NULL values. 

To force a NULL value into those fields you can change your text-file and use the escape character "\N".

mysql> create table a (a float not null);
Query OK, 0 rows affected (0.11 sec)

mysql> insert a values ('');
Query OK, 1 row affected, 1 warning (0.05 sec)

mysql> show warnings;
