Answer 1

You need to do what it says, and set the UpdateCommand Property of the DataAdapter with your SQL UPDATE statement.

SqlDataAdaptor.UpdateCommand property

SqlCommand updateCmd = new SqlCommand();
updateCmd.CommandText = "UPDATE table SET col=@val";

 connexion.da.UpdateCommand = updateCmd;
