SqlConnection Connection = null; Connection = new SqlConnection( myConnectionString ); Connection.Open(); SqlCommand myCommand; myCommand = new SqlCommand( "SELECT * FROM Node " );The error occurs on the last line in the code above. The interesting thing is it did work before I added a new table to the database. I have not even added the code to access the new table yet. And it performs other SQL Select statement (2 actually) before attempting this one.
