findRecord() function

findRecord() returns a row at a specified index as a record from the first table in a stream of tables that matches the specified predicate function.

The function returns an empty record if no table is found or if the index is out of bounds.

Function type signature
(<-tables: stream[B], fn: (key: A) => bool, idx: int) => B where A: Record, B: Record

For more information, see Function type signatures.



(Required) Index of the record to extract.


(Required) Predicate function to evaluate input table group keys.

findColumn() uses the first table that resolves as true. The predicate function requires a key argument that represents each input table’s group key as a record.


Input data. Default is piped-forward data (<-).


Extract a row as a record

import "sampledata"
    |> findRecord(
        fn: (key) => key.tag == "t1",
        idx: 0,
    )// Returns {_time: 2021-01-01T00:00:00.000000000Z, _value: -2, tag: t1}

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
