If the query consists only of tags, the query returns an empty result. See, for example:
> select L1, L2, bytes from rpm limit 3
name: rpm
time L1 L2 bytes

> select L1, L2 from rpm limit 3
> select L2 from rpm limit 3
> # No results
Is this a hard limitation of Influxdb?
The reason why I am asking, in case there is some way to bypass this alltogether, is because I am exploring some data, and the full table spans several screen widths, so being able to select a few keys of interest. But if, by chance, remove all fields, I get nothing, which is not very helpful.
