Translating Legacy BigQuery to Standard and getting error "Table name "s3" cannot be resolved: dataset name is missing."

Question

The error is on line 4 and s3.fullVisitorId is underlined. I imagine it is going to throw an error on each of the selected items in that group though.

I tried adding a SELECT statement after DISTINCT and the inline error goes away but when I try to run the query I get the error: "Table name "s3" cannot be resolved: dataset name is missing."

Any help would be appreciated. I am finding translating queries from legacy sql to standard is a bit of a headache.

Here is the full query:

#standardSQL

  CAST(CONCAT(SUBSTR(date,1,4),'-',SUBSTR(date,5,2),'-',SUBSTR(date,7,2)) AS DATE) AS Date,
  COUNT(DISTINCT s3.fullVisitorId) AS users,
  COUNT(s0.firstHit) AS carts,
  COUNT(s1.firstHit) AS order_details,
  COUNT(s2.firstHit) AS order_confirmation
FROM (
  SELECT
    IFNULL(s3.date,
      IFNULL(s0.date,
        IFNULL(s1.date,
          s2.date))) AS date,
    s3.fullVisitorId,

You have multiple issues here - notably: in lines 14-19

s3.fullVisitorId,
s0.fullVisitorId,
s0.visitId,
s0.firstHit,
s1.firstHit,
s2.firstHit

I would recommend to at least provide aliases like [for example] below

s3.fullVisitorId s3_fullVisitorId,
s0.fullVisitorId s0_fullVisitorId,
s0.visitId,
s0.firstHit s0_firstHit,
s1.firstHit s1_firstHit,
s2.firstHit s2_firstHit

and then in lines 4-7 - reference the alias

COUNT(DISTINCT s3_fullVisitorId) AS users,
COUNT(s0_firstHit) AS carts,
COUNT(s1_firstHit) AS order_details,
COUNT(s2_firstHit) AS order_confirmation
