There are multiple ways to execute queries with InfluxDB.
This guide covers the different options:

- [Data Explorer](#data-explorer)
- [Influx REPL](#influx-repl)
- [Influx query command](#influx-query-command)
- [InfluxDB API](#influxdb-api)

## Data Explorer
Queries can be built, executed, and visualized in InfluxDB UI's Data Explorer.

## Influx REPL
The [`influx repl` command](/v2.0/reference/cli/influx/repl) starts an interactive
read-eval-print-loop (REPL) where you can write and execute Flux queries.

```bash
influx repl --org org-name
```

`ctrl-d` will close the REPL.

## Influx query command
You can pass queries to the [`influx query` command](/v2.0/reference/cli/influx/query)
as either a file or raw Flux via stdin.

###### Run a query from a file
```bash
influx query @/path/to/query.flux
```

###### Pass raw Flux via stdin pipe
```bash
influx query - # Return to open the pipe

data = from(bucket: "example-bucket") |> range(start: -10m) # ...
# ctrl-d to close the pipe and submit the query
```

## InfluxDB API
The [InfluxDB v2 API](/v2.0/reference/api) provides a programmatic
interface for all interactions with InfluxDB.
Query InfluxDB through the `/api/v2/query` endpoint.
Queried data is returned in annotated CSV format.

In your request, set the following:

- Your organization via the `org` or `orgID` URL parameters.
- `Authorization` header to `Token ` + your authentication token.
- `Accept` header to `application/csv`.
- `Content-type` header to `application/vnd.flux`.
- Your plain text query as the request's raw data.

InfluxDB returns the query results in [annotated CSV](/v2.0/reference/syntax/annotated-csv/).

#### Use gzip to compress the query response
To compress the query response, set the `Accept-Encoding` header to `gzip`.
This saves network bandwidth, but increases server-side load.

Below is an example `curl` command that queries InfluxDB:

{{% code-tabs %}}

{{% /code-tabs %}}

{{% code-tab-content %}}
```bash
curl http://localhost:9999/api/v2/query?org=my-org -XPOST -sS \
  -H 'Authorization: Token YOURAUTHTOKEN' \
  -H 'Accept: application/csv' \
  -H 'Content-type: application/vnd.flux' \
  -d 'from(bucket:"example-bucket")
        |> range(start:-1000h)
        |> group(columns:["_measurement"], mode:"by")
        |> sum()'
```
{{% /code-tab-content %}}

{{% code-tab-content %}}
```bash
curl http://localhost:9999/api/v2/query?org=my-org -XPOST -sS \
  -H 'Authorization: Token YOURAUTHTOKEN' \
  -H 'Accept: application/csv' \
  -H 'Content-type: application/vnd.flux' \
  -H 'Accept-Encoding: gzip' \
  -d 'from(bucket:"example-bucket")
        |> range(start:-1000h)
        |> group(columns:["_measurement"], mode:"by")
        |> sum()'
```
