This page documents an earlier version of InfluxDB. InfluxDB v2.7 is the latest stable version. View this page in the v2.7 documentation.
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 is a functional data scripting language designed for querying, analyzing, and acting on data.
InfluxQL is an SQL-like query language for interacting with data in InfluxDB.
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.
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.
InfluxDB uses an InfluxQL-like predicate syntax to determine what data points to delete.
