v1.measurementFieldKeys() function
Deprecated
v1.measurementFieldKeys() was deprecated in Flux v0.88.0 in favor of
schema.measurementFieldKeys().
v1.measurementFieldKeys() returns a list of fields in a measurement.
Results include a single table with a single column, _value.
Function type signature
(bucket: string, measurement: A, ?start: B, ?stop: C) => stream[D] where A: Equatable, D: Record
Parameters
bucket
(Required) Bucket to retrieve field keys from.
measurement
(Required) Measurement to list field keys from.
start
Oldest time to include in results. Default is -30d.
stop
Newest time include in results.
The stop time is exclusive, meaning values with a time equal to stop time are excluded from the results.
Default is now().
Relative start times are defined using negative durations.
Negative durations are relative to now().
Absolute start times are defined using time values.
Examples
Query field keys from an InfluxDB measurement
import "influxdata/influxdb/schema"
schema.measurementFieldKeys(bucket: "example-bucket", measurement: "example-measurement")
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.
