`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

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

## Parameters

### idx
({{< req >}})
Index of the record to extract.



### fn
({{< req >}})
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.

### tables

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




## Examples

### Extract a row as a record

```js
import "sampledata"

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


```
