# 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](/api-reference/go/workflows/Collect) to transform the sequence into a slice.

## Parameters

<ParamField path="jobID" type="uuid.UUID" required>
  The ID of the job to query spans for.
</ParamField>

<ParamField path="options" type="[]job.TelemetryQueryOption">
  Options for querying spans.
</ParamField>

## Options

<ParamField path="job.WithCursor(cursor *job.Cursor)">
  Start the query after the cursor returned by a previous page.
</ParamField>

<ParamField path="job.WithLimit(limit int64)">
  Limit the total number of spans yielded by the sequence.
</ParamField>

<ParamField path="job.WithSortDirection(direction job.SortDirection)">
  Sort spans by start time. Use `job.Ascending` for oldest first or `job.Descending` for newest first.
</ParamField>

## Returns

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

  import (
      "fmt"
      "log/slog"

      "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(),
      )
  }
  ```
