Parameters

rows

({{< req >}}) Array of records to construct a table with.

Build an arbitrary table

import "array"

rows = [{foo: "bar", baz: 21.2}, {foo: "bar", baz: 23.8}]

array.from(rows: rows)

{{< expand-wrapper >}} {{% expand "View example output" %}}

Output data

foo	baz
bar	21.2
bar	23.8

{{% /expand %}} {{< /expand-wrapper >}}

Union custom rows with query results

import "influxdata/influxdb/v1"
import "array"

tags = v1.tagValues(bucket: "example-bucket", tag: "host")

wildcard_tag = array.from(rows: [{_value: "*"}])

union(tables: [tags, wildcard_tag])
