Я пытаюсь удалить все строки, которые имеют productRef = productAssociated
.
Я пробовал запрос ниже, но последняя строка не работает.
Что не так?
SELECT date, transaction.transactionId,
ref.productSKU as productRef,
associated.productSKU as productAssociated,
ARRAY_LENGTH(hits.product) as nbProducts
FROM `dl-recommendation-engine.NDA_CHANEL_137002018.ga_sessions_*` as session,
UNNEST(hits) AS hits,
UNNEST(hits.product) as ref,
UNNEST(hits.product) as associated
WHERE _TABLE_SUFFIX BETWEEN '20191122' AND '20191202' AND
hits.transaction.transactionId IS NOT NULL AND
ARRAY_LENGTH(hits.product) > 2 AND
productAssociated != productRef
