Answer 1

Dans votre requête, vous donnez l'alias hit aux éléments retournés par UNNEST(hits) et l'alias customDimension aux éléments retournés par UNNEST(customDimensions). Si vous souhaitez faire référence à un hit particulier plutôt qu'au tableau, utilisez à la place hit et si vous souhaitez faire référence à une seule dimension personnalisée, utilisez plutôt customDimension. Par exemple, votre filtre peut être quelque chose comme:

WHERE _TABLE_SUFFIX BETWEEN '20161025' AND '20161026' AND 
    hit.page.hostname LIKE '%website.fr%' AND 
    customDimension.value != "null" AND 
    hit.page.pagePath LIKE '%poiu%' AND 
    hit.type = 'PAGE' AND 
    customDimension.index IN (1, 11, 14, 27) 

Answer 2

Il ya quelques erreurs que j'ai trouvées dans la requête. J'ai fait les corrections, j'espère que cela vous aidera.
