SQL Has Problems. We Can Fix Them: Pipe Syntax In SQL (via) A new paper from Google Research describing custom syntax for analytical SQL queries that has been rolling out inside Google since February, reaching 1,600 "seven-day-active users" by August 2024.
A key idea is here is to fix one of the biggest usability problems with standard SQL: the order of the clauses in a query. Starting with SELECT instead of FROM has always been confusing, see SQL queries don't start with SELECT by Julia Evans.
Here's an example of the new alternative syntax, taken from the Pipe query syntax documentation that was added to Google's open source ZetaSQL project last week.
For this SQL query:
SELECT component_id, COUNT(*)
FROM ticketing_system_table
WHERE
assignee_user.email = '[email protected]'
AND status IN ('NEW', 'ASSIGNED', 'ACCEPTED')
GROUP BY component_id
ORDER BY component_id DESC;The Pipe query alternative would look like this:
FROM ticketing_system_table
|> WHERE
assignee_user.email = '[email protected]'
AND status IN ('NEW', 'ASSIGNED', 'ACCEPTED')
|> AGGREGATE COUNT(*)
GROUP AND ORDER BY component_id DESC;
The Google Research paper is released as a two-column PDF. I snarked about this on Hacker News:
Google: you are a web company. Please learn to publish your research papers as web pages.
This remains a long-standing pet peeve of mine. PDFs like this are horrible to read on mobile phones, hard to copy-and-paste from, have poor accessibility (see this Mastodon conversation) and are generally just bad citizens of the web.
Having complained about this I felt compelled to see if I could address it myself. Google's own Gemini Pro 1.5 model can process PDFs, so I uploaded the PDF to Google AI Studio and prompted the gemini-1.5-pro-exp-0801 model like this:
Convert this document to neatly styled semantic HTML
This worked surprisingly well. It output HTML for about half the document and then stopped, presumably hitting the output length limit, but a follow-up prompt of "and the rest" caused it to continue from where it stopped and run until the end.
Here's the result (with a banner I added at the top explaining that it's a conversion): Pipe-Syntax-In-SQL.html
I haven't compared the two completely, so I can't guarantee there are no omissions or mistakes.
The figures from the PDF aren't present - Gemini Pro output tags like <img src="figure1.png" alt="Figure 1: SQL syntactic clause order doesn't match semantic evaluation order. (From [25].)"> but did nothing to help me create those images.
Amusingly the document ends with <p>(A long list of references, which I won't reproduce here to save space.)</p> rather than actually including the references from the paper!
So this isn't a perfect solution, but considering it took just the first prompt I could think of it's a very promising start. I expect someone willing to spend more than the couple of minutes I invested in this could produce a very useful HTML alternative version of the paper with the assistance of Gemini Pro.
One last amusing note: I posted a link to this to Hacker News a few hours ago. Just now when I searched Google for the exact title of the paper my HTML version was already the third result!
I've now added a <meta name="robots" content="noindex, follow"> tag to the top of the HTML to keep this unverified AI slop out of their search index. This is a good reminder of how much better HTML is than PDF for sharing information on the web!
