code: public QueryBuilder<T, ID> selectRaw(String... columns) {
  		for (String column : columns) {
  			addSelectToList(ColumnNameOrRawSql.withRawSql(column));
  		}
  		return this;
  	}
docs: Add raw columns or aggregate functions (COUNT, MAX, ...) to the query. This will turn the query into something
  only suitable for the {@link Dao#queryRaw(String, String...)} type of statement. This can be called multiple
  times to add more columns to select.
