Feature request: Show Query Field if All Values Null

[vancelopez]

Related to this issue in the SFDC developer forums. If a queried field has all null values, it will omit the field from the results. Example:

SELECT Id, Total_Bookings__c FROM Account

If Total_Bookings__c has no values (is null) in all records, then it will omit that field from the results. If stored in object df, df will be a data frame with 1 column, Id.

Is it possible to get the null field in the results?
