_**Flux package:** [InfluxDB schema](/{{< latest "flux" >}}/stdlib/influxdata/influxdb/schema/)  
**Flux functions:** [schema.measurementTagValues()](/{{< latest "flux" >}}/stdlib/influxdata/influxdb/schema/measurementtagvalues/)_

```js
import "influxdata/influxdb/schema"

schema.measurementTagValues(
  bucket: "bucket-name",
  measurement: "measurement-name",
  tag: "_field"
)
```

## List unique tag values
