InfluxDB OSS v2

InfluxDB syntaxes

This page documents an earlier version of InfluxDB OSS. InfluxDB 3 Core is the latest stable version.

InfluxDB uses a handful of languages and syntaxes to perform tasks such as writing, querying, processing, and deleting data. The following articles provide information about the different syntaxes used with InfluxDB and the contexts in which they’re used:

Flux

Flux is a functional data scripting language designed for querying, analyzing, and acting on data.

InfluxQL

InfluxQL is an SQL-like query language for interacting with data in InfluxDB.

Line protocol

InfluxDB uses line protocol to write data points. It is a text-based format that provides the measurement, tag set, field set, and timestamp of a data point.

Annotated CSV

InfluxDB and Flux return query results in annotated CSV format. You can also read annotated CSV directly from Flux with the csv.from() function, write data to InfluxDB using annotated CSV and the influx write command, or upload a CSV file in the UI.

Delete predicate

InfluxDB uses an InfluxQL-like predicate syntax to determine what data points to delete.
