This section introduces InfluxQL, InfluxDB’s SQL-like query language for interacting with data in InfluxDB.

InfluxQL Tutorial

The first seven documents in this section provide a tutorial-style introduction to InfluxQL. Feel free to download the dataset provided in Sample Data and follow along with the documentation.

Data exploration

Data Exploration covers the query language basics for InfluxQL, including the SELECT statement, GROUP BY clauses, INTO clauses, and more. See Data Exploration to learn about time syntax and regular expressions in queries.

Schema exploration

Schema Exploration covers queries that are useful for viewing and exploring your schema. See Schema Exploration for syntax explanations and examples of InfluxQL’s SHOW queries.

Database management

Database Management covers InfluxQL for managing databases and retention policies in InfluxDB. See Database Management for creating and dropping databases and retention policies as well as deleting and dropping data.

Functions

Functions covers all InfluxQL functions.

Continuous queries

Continuous Queries covers the basic syntax , advanced syntax , and common use cases for Continuous Queries. This page also describes how to SHOW and DROP Continuous Queries.

Mathematical operators

Mathematical Operators covers the use of mathematical operators in InfluxQL.
