Google's new pipe syntax in SQL

>>heyden+(OP)
Richard Hipp, creator of SQLite, has implemented this in an experimental branch: https://sqlite.org/forum/forumpost/5f218012b6e1a9db

Worth reading the thread, there are some good insights. It looks like he will be waiting on Postgres to take the initiative on implementing this before it makes it into a release.

FROM first would be nothing short of incredible. I can only hope that Postgres and others can find it within themselves to get together and standardize on such an extension!

>>Blackt+FS9
Yeap I didn't know DuckDB supported it already!

Being able to do SELECT FROM WHERE in any order and allowing multiple WHEREs and AGGREGATE etc, combined with supporting trailing commas, makes copy pasting templating and reusing and code-generating SQL so much easier.

  FROM table  <-- at this point there is an implicit SELECT *
  SELECT whatever
  WHERE some_filter
  WHERE another_filter <-- this is like AND
  AGGREGATE something
  WHERE a_filter_that_is_after_grouping <-- is like HAVING
  ORDER BY ALL <-- group-by-all is great in engines that support it; want it for ordering too

...

What’s group-by-all? Sounds like distinct?

>>aidos+aAa
Normally the SELECT has a bunch of columns to group by and a bunch of columns that are aggregates. Then, in the GROUP BY clause, you have to list all the columns to group by. The query compiler knows which they are, and polices you, making sure you got it right. All the GROUP BY ALL does is say 'the compiler knows, there's no need to list them all'. Very convenient.

BigQuery supports GROUP BY ALL and it really cleans up lots of queries. E.g.

   SELECT foo, bar, SUM(baz)
   FROM x
   GROUP BY ALL <-- equiv to GROUP BY foo, bar

(eh, except MySQL; my memory of MySQL is it will silently do ANY_VALUE() on any columns that aren't an explicit aggregate function but are not grouped; argh it was a long time ago)

>>willva+tCa
MySQL doesn't do this anymore; the ONLY_FULL_GROUP_BY mode became default in 5.7 (I think). You can still turn it off and get the old behavior, though.
