I'm glad to see pipe syntax moving forward! In my time at Google, I wrote a lot of SQL queries that required a long sequence of intermixed filtering, grouping, aggregation, and analytic window operations. But the ordering of those operations rarely matched SQL's inside-out syntax, so I commonly had to chop up my logic and glue it into multiple chained CTEs. This busywork made my code's logic harder to follow and was frustrating, especially since I was familiar with alternative coding models, such as R's dplyr, that would have allowed me to express my logic as a simple linear pipeline.
I hope SQL pipes become commonplace so that I can use them anywhere I have to write SQL queries.
