## Code sample

### Go


Before trying this sample, follow the Go setup instructions in the
[BigQuery quickstart using
client libraries](https://docs.cloud.google.com/bigquery/docs/quickstarts/quickstart-client-libraries).


For more information, see the
[BigQuery Go API
reference documentation](https://godoc.org/cloud.google.com/go/bigquery).


To authenticate to BigQuery, set up Application Default Credentials.

[Set up authentication for client libraries](https://docs.cloud.google.com/bigquery/docs/authentication#client-libs).

    import (
    	"context"
    	"fmt"
    	"io"

    	"cloud.google.com/go/bigquery"
    )

    // getView demonstrates fetching the metadata from a BigQuery logical view and printing it to an io.Writer.
    func getView(w io.Writer, projectID, datasetID, viewID string) error {
    	// projectID := "my-project-id"
    	// datasetID := "mydataset"
    	// viewID := "myview"
    	ctx := context.Background()
    	client, err := bigquery.NewClient(ctx, projectID)
    	if err != nil {
    		return fmt.Errorf("bigquery.NewClient: %w", err)
    	}
    	defer client.Close()

    	view := client.Dataset(datasetID).Table(viewID)
    	meta, err := view.Metadata(ctx)
    	if err != nil {
    		return err
    	}
    	fmt.Fprintf(w, "View %s, query: %s\n", view.FullyQualifiedName(), meta.ViewQuery)
    	return nil
    }
