Create bqutil UDFs in all other non-US datasets

I ran into some issues when trying to use CTE’s in combination with bqutil.

This exectues as expected:

SELECT `bqutil.fn.median`([1,1,1,2,3,4,5,100,1000]) as median

However, after adding a CTE:

WITH covid AS (
  SELECT date, daily_confirmed_cases 
  FROM `bigquery-public-data.covid19_ecdc_eu.covid_19_geographic_distribution_worldwide` 
)
SELECT `bqutil.fn.median`([1,1,1,2,3,4,5,100,1000]) as median

BQ throws the error: “Function not found: bqutil.fn.median”.

I there a way to explicitly import the BQ utils or any other suggestions to address this issue?

@danieldeleo Apologies for commenting on this closed issue, do you anticipate that bqutil be publicly available in non-US locations or if we are outside the US should we always deploy our own? Thanks

It’s not clear from the error message, but this is caused by the table and the UDF being in different BigQuery dataset locations, and the query must be processed in only one location. By default, BigQuery will attempt to process your query in EU location since bigquery-public-data.covid19_ecdc_eu.covid_19_geographic_distribution_worldwide is stored in EU. The bqutil.fn dataset is only available in US location for now, so the query errors because it cannot find the UDF in the EU location. For now, you can create the UDF as either a persistent UDF in your own dataset, or as a temporary UDF in a script along with your query.

I will assign this issue to myself to have all the bqutil UDFs created in the other non-US locations
