Group by nothing

[vfournier11]

When I do a SELECT * FROM measurements I get multiples series.

It is possible to group the results by one/several tags using GROUP BY [tagname].

Now, can I group all results?

Is it possible to make a GROUP BY "nothing" to have all series merged together?

This is current design but not the long-term desired behavior. Unfortunately, with SELECT * there is currently a hack/workaround that implicitly does a GROUP BY * to return the tags. As such, SELECT * cannot currently be executed without at least an implicit hidden GROUP BY.

SELECT fieldval1, fieldval2, etc. with no GROUP BY will automatically merge all series together, but you will need to explicitly name the fields you wish to query.
