How to track DuckDuckGo search traffic in Google Analytics (or Analytics 360)
Sometime ago the BigQuery Team renamed its SQL dialect to Legacy SQL and introduced beta support of ANSI 2011 SQL named Standard SQL in the BigQuery world.
This made life easier for the huge army of Digital Analysts, Data Science specialists, SQL developers and surely for me. Except that now I have had to migrate all the queries written in the last couple of years to a new Standard SQL. While it is true that in BigQuery, Standard SQL dialect is still at a beta stage it is pretty usable and tools like Tableau force users to switch.
Migrating from Legacy SQL to Standard SQL in BigQuery is a very straightforward process and for every single query I was able to get exactly the same query result by only fixing the dialect syntax leaving semantical structure untouched. As a second stage in the process, I modified some queries to better reflect Standard SQL (ANSI 2011) ideology, making queries simpler and easier to read. I didn't notice any substantial performance gain though. In fact, many queries written and adopted for Standard SQL executed 1.2 - 1.5 times slower than in Legacy SQL! What I have also noticed is that the internal caching engine does not work as well as it did for Legacy SQL. Well, that's probably why BigQuery Standard SQL is still in beta.
Instead of using the square brackets, we now use the "`" symbol and project name and dataset name is now separated with a dot instead of a semicolon
The changes above are very straightforward and could even be done on multiple queries using regex
SELECT ROUND(MAX(totals.totalTransactionRevenue) / 1000000) as maxTransactionRevenue
WHERE _TABLE_SUFFIX between '20170101' and '20170131'
The pseudo-column _TABLE_PREFIX really made queries look cleaner and allowed for more freedom in some complex JOINs
AND trafficSource.campaign LIKE '%dom%' --faster
AND REGEXP_CONTAINS(trafficSource.campaign, 'dom') --slower
