title: CAST BYTES to STRING in BigQuery
body: <p>I created the following script in Google Big Query:</p>
  <p>SELECT CAST(user_ID AS STRING) FROM <code>table</code></p>
  <p>I recevied the error message: Invalid cast of bytes to UTF8 string</p>
  <p>How can I overpass this and and join the user_id with a another one which is string?</p>
