[influxdb] In Influxdb, how do I concat values in my query?

[Dhawal Patel]

I would like to query all rows where columnA = 'xyz' + columnB:

select * from myTable where colA = 'xyz' + colB

tables and rows don't exist in InfluxDB, but I think you're asking for 
`select * from measurement where tag = 'string' + another_tag`
That's not a valid query in the current syntax. Can you provide an actual use case for that? I'm not following what you're trying to accomplish.
Note that InfluxDB supports regular expression matching for tags, so `select * from measurement where tag =~ /xyx.*/` is valid

A use case is formatting for grafana annotations. I want to concatenate multiple fields for the text section of the grafana annotation.
