Hi,
I got error "No value given for one or more required parameters" error when executing the following code. I checked the value of the query and it seems correct. Does anyone know why?
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\Catherine\\Documents\\LearningCSharp.accdb";
OleDbConnection myConnection = new OleDbConnection(connectionString);
myConnection.Open();
int employeeNumber = int.Parse(textBox1.Text);
string name = textBox2.Text;
string address = textBox3.Text;
string query = "update EMPLOYEE set EmployeeName='"+ name + "', Address='"+ address + "' where EmployeeID = "+ employeeNumber;
OleDbCommand myCommand = new OleDbCommand();
myCommand.CommandText = query;
myCommand.Connection = myConnection;
myCommand.ExecuteNonQuery();
myConnection.Close();
Thanks in advance.
