I want to get list hits.eventInfo.eventAction in Google Analytics data via BigQuery using this code:
SELECT DISTINCT hits.eventInfo.eventAction FROM `ga_sessions_*`
But the error like this:
Cannot access field eventInfo on a value with type ARRAY<STRUCT<hitNumber INT64, time INT64
I try to add UNNEST(hits) but also error. Any suggestion?
Can you try the query below, I used UNNEST:
SELECT DISTINCT hits.eventInfo.eventAction FROM `bigquery-public-data.google_analytics_sample.ga_sessions_*`, UNNEST(hits) as hits
Output:

I am trying to get new table with EventInfo from my GA view such as EventAction, EventCategory and EventLabel. But I face the following problem
Cannot access field eventInfo on a value with type ARRAY<STRUCT<hitNumber INT64, time INT64, hour INT64, ...>> at [2:6]
Even after trying to compose query as mentioned above, I am getting an error.
ARRAY>
Could you please let me know how to fix it?
Below example for BigQuery Standard SQL
#standardSQL
SELECT visitId, visitNumber, hit.eventInfo.*
FROM `bigquery-public-data.google_analytics_sample.ga_sessions_20170801`,
UNNEST(hits) hit
WHERE NOT eventInfo IS NULL
with result as something like below
visitId visitNumber eventCategory eventAction eventLabel eventValue
1501607501 1 Enhanced Ecommerce Quickview Click YouTube Men's Vintage Henley null
1501633019 1 Enhanced Ecommerce Quickview Click YouTube Custom Decals null
We have created a hit level custom metric in google analytics that I want to retrieve in BigQuery. When running the following query:
#StandardSQL
SELECT h.page.pagePath, SUM(h.customMetrics.value)
FROM `141884522.ga_sessions_20181024`, UNNEST(hits) as h
GROUP BY h.page.pagePath
I get this error:
Error: Cannot access field value on a value with type ARRAY<STRUCT<index
INT64, value INT64>> at [2:45]
I can select just h.customMetrics (without grouping) which returns h.customMetrics.value and h.customMetrics.index but I cannot select the value or index specifically.
Anyone knows how to do that?
#standardSQL
SELECT h.page.pagePath, SUM(metric.value)
FROM `141884522.ga_sessions_20181024`, UNNEST(hits) AS h, UNNEST(h.customMetrics) metric
GROUP BY h.page.pagePath
Btw, if you want to see all pagePath's even those with missing metrics (in cse if it is a case with your data) - i would recommend replacing CROSS JOIN with LEFT JOIN as in below example
#standardSQL
SELECT h.page.pagePath, SUM(metric.value)
FROM `141884522.ga_sessions_20181024`, UNNEST(hits) AS h
LEFT JOIN UNNEST(h.customMetrics) metric
GROUP BY h.page.pagePath
I want to get the total sessions but just because I am unnesting 'hit.product' and 'hits' at same time as shown in the below code, its giving me less session count than that I can see in GA. I am suspecting that it is filtering out the sessions that doesn't have any products.
There is also a way that i can handle that without using unnest by using Array as shown below
ARRAY(SELECT DISTINCT v2ProductCategory FROM UNNEST(hits.product)) AS v2ProductCategory
Is there any way if I can pull all the sessions and its product category, product name and hits info(hits.time, hits.page.pagepath) without using ARRAY which I would be using it in my further analysis?
select count(distinct session) from(SELECT
fullvisitorid,
CONCAT(CAST(fullVisitorId AS string),CAST(visitId AS string)) AS session,
hits.time,
hits.page.pagePath,
hits.eCommerceAction.action_type,
product.v2ProductCategory,
product.v2ProductName
FROM
`XXXXXXXXXXXXXXX`,
UNNEST(hits) AS hits,
UNNEST(hits.product) AS product
WHERE
_TABLE_SUFFIX BETWEEN "20170930"
AND "20170930")
I create Google Analytics data source in Tableau.
The data source has the segment by "new user".
Now, I would like to push the Google Analytics in Google Bigquery and create the same data source in Tableau by creating a data source from Google Bigquery.
After checking the GA data source in Google Bigquery project.
There is no segment in Bigquery.
How to query by segment "new user" in Google Bigquery??
You can look at BigQuery GA Schema to see all fields that are exported there.
The field totals.newVisits has what you are looking for:
select
hits.transaction.transactionid tid,
date,
totals.pageviews pageviews,
hits.item.itemquantity item_qtd,
hits.transaction.transactionrevenue / 1e6 rvn,
totals.bounces bounces,
fullvisitorid fv,
visitid v,
totals.timeonsite tos,
totals.newVisits new_visit
FROM
`project_id.dataset_id.ga_sessions*`,
unnest(hits) hits
WHERE
1 = 1
AND PARSE_TIMESTAMP('%Y%m%d', REGEXP_EXTRACT(_table_suffix, r'.*_(.*)')) BETWEEN TIMESTAMP('2017-05-10')
AND TIMESTAMP('2017-05-10')
group by
tid, date, pageviews, item_qtd, rvn, bounces, fv, v, tos, new_visit
Notice that this field is defined in the session level.
I am migrating to the new SQL syntax in BigQuery, since it seems more flexible. However I am a bit stuck when it comes to access the fields in the customDimensions. I am writing something quite simple like this:
SELECT
cd.customDimensions.index,
cd.customDimensions.value
FROM `xxxxx.ga_sessions_20170312`, unnest(hits) cd
limit 100
But I get the error
Error: Cannot access field index on a value with type ARRAY<STRUCT<index INT64, value STRING>>
However if I run something like this works perfectly fine:
SELECT
date,
SUM((SELECT SUM(latencyTracking.pageLoadTime) FROM UNNEST(hits))) pageLoadTime,
SUM((SELECT SUM(latencyTracking.serverResponseTime) FROM UNNEST(hits))) serverResponseTime
FROM `xxxxxx.ga_sessions_20170312`
group by 1
Is there some different logic when it comes to query the customDimensions?
If the intention is to retrieve all custom dimensions in a flattened form, then join with UNNEST(customDimensions) as well:
#standardSQL
SELECT
cd.index,
cd.value
FROM `xxxxx.ga_sessions_20170312`,
unnest(hits) hit,
unnest(hit.customDimensions) cd
limit 100;
SELECT
fullvisitorid,
( SELECT MAX(IF(index=1,value, NULL))FROM UNNEST(hits.customDimensions)) AS CustomDimension1,
( SELECT MAX(IF(index=2,value, NULL))FROM UNNEST(hits.customDimensions)) AS CustomDimension2
FROM
`XXXXXXX`, unnest(hits) as hits
