# v1 package

-   Flux 0.16.0+
-   View InfluxDB support

The `v1` package provides tools for managing data from an InfluxDB v1.x database or structured using the InfluxDB v1 data structure. Import the `influxdata/influxdb/v1` package:

```js
import "influxdata/influxdb/v1"
```

### Deprecated functions

In Flux 0.88.0, the following v1 package functions moved to the InfluxDB schema package. These functions are still available in the v1 package for backwards compatibility, but are deprecated in favor of the schema package.

-   `v1.fieldKeys()`
-   `v1.fieldsAsCols()`
-   `v1.measurementFieldKeys()`
-   `v1.measurements()`
-   `v1.measurementTagKeys()`
-   `v1.measurementTagValues()`
-   `v1.tagKeys()`
-   `v1.tagValues()`

#### Not supported in the Flux REPL

`v1` functions can retrieve schema information when executed within the context of InfluxDB, but not from the [Flux REPL](/influxdb/cloud/tools/repl/).
