seotitle: Query fields and tags in InfluxDB using Flux
|
|
description: >
|
|
Use `filter()` to query data based on fields, tags, or any other column value.
|
|
`filter()` performs operations similar to the `SELECT` statement and the `WHERE`
|
|
clause in InfluxQL and other SQL-like query languages.
