duration() function
The duration() function converts a single value to a duration.
Output data type: Duration
duration(v: "1m")
Parameters
v
(Required) Value to convert.
duration() assumes numeric input values are nanoseconds.
String input values must use duration literal representation.
Examples
- Convert an integer to a duration
- Convert a string to a duration
- Convert values in a column to durations
Convert an integer to a duration
duration(v: 120000000)
// Returns 120ms
Convert a string to a duration
duration(v: "12h30m")
// Returns 12h30m
Convert values in a column to durations
The following example uses generate.from()
to generate sample data and show how to iterate over values in a stream of tables
and convert them to duration values.
Flux does not support duration column types. This example converts an integer to a duration and stores the value as a string.
import "generate"
data = generate.from(
count: 5,
fn: (n) => (n + 1) * 3600000000000,
start: 2021-01-01T00:00:00Z,
stop: 2021-01-01T05:00:00Z,
)
data
|> map(fn:(r) => ({ r with _value: string(v: duration(v: r._value)) }))
