InfluxQL - InfluxDB 1.x

InfluxQL is an SQL-like query language for interacting with InfluxDB. It has been crafted to feel familiar to those coming from other SQL or SQL-like environments while also providing features specific to storing and analyzing time series data. However InfluxQL is not SQL and lacks support for more advanced operations like UNION, JOIN and HAVING that SQL power-users are accustomed to. This functionality is available with Flux.
