SQL Has Problems. We Can Fix Them: Pipe Syntax In SQL (research.google)
submitted 3 months ago by [email protected] to c/programming

Really intriguing article about a SQL syntax extension that has apparently already been trialed at Google.

As someone who works with SQL for hours every week, this makes me hopeful for potential improvements, although the likelihood of any changes to SQL arriving in my sector before I retire seems slim.

If this is something likely to change I'd space it out - but mid-line diffs are usually pretty readable in most clients.

As always, expression should cater to readability and shouldn't be limited by syntax rules.

No matter which tool you're using, this:

- |> LEFT JOIN |> FROM foo |> GROUP BY clusterid |> SELECT clusterid, COUNT(*)
+ |> LEFT JOIN |> FROM foobar |> GROUP BY clusterid |> SELECT clusterid, COUNT(*)
      ON cluster.id = foo.clusterid

Is always less readable than:

  |> LEFT JOIN 
- |> FROM foo 
+ |> FROM foobar
  |> GROUP BY clusterid 
  |> SELECT clusterid, COUNT(*)
      ON cluster.id = foo.clusterid

And this isn't even the worst example I've seen. That would be a file that had a bug due to duplicated entries in a list, and it became very obvious as soon as I converted it to something akin to the second version.
