# Jobs.QuerySpans

```go theme={"system"}
func (*JobClient) QuerySpans(
    ctx context.Context,
    jobID uuid.UUID,
    options ...job.TelemetryQueryOption,
) iter.Seq2[*workflows.Span, error]
```

Query spans emitted while running a job.

The spans are lazily loaded and returned as a sequence of spans. Use [Collect](https://docs-old.tilebox.com/api-reference/go/workflows/Collect.md) to transform the sequence into a slice.

## Parameters

**jobID** `uuid.UUID` *required*

The ID of the job to query spans for.

**options** `[]job.TelemetryQueryOption`

Options for querying spans.

## Options

\**job.WithCursor(cursor *job.Cursor)**

Start the query after the cursor returned by a previous page.

**job.WithLimit(limit int64)**

Limit the total number of spans yielded by the sequence.

**job.WithSortDirection(direction job.SortDirection)**

Sort spans by start time. Use `job.Ascending` for oldest first or `job.Descending` for newest first.

## Returns

A sequence of spans. Each span includes `StartTime`, `Name`, `StatusCode`, `Attributes`, and `Duration()`.

```go Go theme={"system"}
import (
    "fmt"
    "log/slog"
    "time"

    "github.com/google/uuid"
    "github.com/tilebox/tilebox-go/workflows/v1"
    "github.com/tilebox/tilebox-go/workflows/v1/job"
)

jobID := uuid.MustParse("019e07b1-916b-0630-f3ba-f1c33235d174")

for span, err := range client.Jobs.QuerySpans(
    ctx,
    jobID,
    job.WithSortDirection(job.Ascending),
) {
    if err != nil {
        slog.ErrorContext(ctx, "failed to query job spans", slog.Any("error", err))
        return
    }

    fmt.Printf("%s %-40s %s\n",
        span.StartTime.Format(time.RFC3339),
        span.Name,
        span.Duration(),
    )
}
