问使用go更新/覆盖而不是插入插入到bigquery中

EN

client, err := bigquery.NewClient(ctx, projectID, gcpOption)
if err != nil {
    println(fmt.Sprintf("error creating new client, %v", err))
    return fmt.Errorf("bigquery.NewClient: %v", err)
}
defer client.Close()

inserter := client.Dataset(datasetID).Table(tableID).Inserter()
if err := inserter.Put(ctx, items); err != nil {
    println(fmt.Sprintf("error inserting, %v", err))
    if multiError, ok := err.(bigquery.PutMultiError); ok {
        for _, err1 := range multiError {
            for _, err2 := range err1.Errors {
                fmt.Println(err2)
            }
        }
    } else {
        fmt.Println(err)
    }
    return err
} else {
    println("Inserted record")
}
