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

## Functions

* [schema.fieldsAsCols()](/flux/v0/stdlib/influxdata/influxdb/schema/fieldsascols/)
* [schema.measurementFieldKeys()](/flux/v0/stdlib/influxdata/influxdb/schema/measurementfieldkeys/)
* [schema.measurements()](/flux/v0/stdlib/influxdata/influxdb/schema/measurements/)
* [schema.measurementTagKeys()](/flux/v0/stdlib/influxdata/influxdb/schema/measurementtagkeys/)
* [schema.measurementTagValues()](/flux/v0/stdlib/influxdata/influxdb/schema/measurementtagvalues/)
* [schema.tagKeys()](/flux/v0/stdlib/influxdata/influxdb/schema/tagkeys/)
* [schema.tagValues()](/flux/v0/stdlib/influxdata/influxdb/schema/tagvalues/)

#### Not supported in the Flux REPL

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