How would I go about selecting more columns with this query

I just need to know how I would place more table columns in this query,
like major ect.
Thank you!
MySqlDataAdapter adap = new MySqlDataAdapter(@"SELECT * FROM student", conn);
MySqlCommandBuilder sqlCmd = new MySqlCommandBuilder(adap);
DataSet sqlSet = new DataSet();
adap.Fill(sqlSet, "studentNumber");
conn.Close();
return sqlSet;
