把access的处理函数 换成sql server2005?该怎么处理

public static DataSet ExecuteDataSet(CommandType commandType, string procedureName)        {            using (OleDbConnection connection = new OleDbConnection())            {                connection.ConnectionString = ConnectionString;                OleDbCommand command = new OleDbCommand();                command.CommandText = procedureName;                command.CommandType = commandType;                command.Connection = connection;                connection.Open();                OleDbDataAdapter adapter = new OleDbDataAdapter();                adapter.SelectCommand = command;                DataSet dataSet = new DataSet();                adapter.Fill(dataSet);                connection.Close();                connection.Dispose();                return dataSet;            }        }

public static DataSet ExecuteDataSet(CommandType commandType, string procedureName)        {            using (SqlConnection connection = new SqlConnection())            {                connection.ConnectionString = ConnectionString;                SqlCommand command = new SqlCommand ();                command.CommandText = procedureName;                command.CommandType = commandType;                command.Connection = connection;                connection.Open();                SqlDataAdapter adapter = new SqlDataAdapter();                adapter.SelectCommand = command;                DataSet dataSet = new DataSet();                adapter.Fill(dataSet);                connection.Close();                connection.Dispose();                return dataSet;            }        }
