Google BigQuery - Updating a nested repeated field

Question

Answer 1

This should help get you started. You need to include everything else from hits in order to perform the update, including the nested page.

UPDATE `you_dataset.tablename`
SET hits = ARRAY(
  SELECT AS STRUCT * REPLACE (
    (SELECT AS STRUCT page.* REPLACE ('foo' AS pagePath)) AS page
  )
  FROM UNNEST(hits) as pagePath
)
WHERE fullVisitorID like "%1%"
