Show HN: Describe SQL using natural language, and execute against real data

bob1029|4 years ago

This demo sent us on a warpath today. We have a fairly clean SQL schema for which we need to craft a lot of queries that handle things like business logic, reporting and configuration.

If we could get even 50% success rate on a reasonable starting point for the generated SQL each time, that would be the biggest value-add our organization has ever seen.

I think our use case is compelling because we have to implement the same SQL targets for every customer. The only variations are typically customer-specific parameters/codes/etc.

We also have a huge corpus of examples to pull from for training data.

We are thinking about initially implementing some higher order views/functions in our SQL dialect to make things easier on ourselves with the GPT model. Complex joins across many tables seems to be something that would still elude these techniques. Most of our joins are of a very particular shape, so we can abstract the super nasty stuff away.

Worst case scenario, this concludes like my cynical mind assumes it will, but I am open to being surprised this time. We aren't going to put everything behind this, more of a "if it works..." kind of 1-2 week experiment.

There are projects out there that do this.

Possibly relevant: https://yale-lily.github.io/spider

I briefly worked on a startup to commercialize this tech, but we decided it wasn't accurate enough to be useful. It was very cool when it actually worked. If you can only produce what you want half the time on simple queries, that doesn't seem very useful to me though.

Shoot me an email if you’d like—I’d be happy to share any learnings from what I built if relevant.

newusertoday|4 years ago

Have you considered using templates? can you elaborate more on why they can't be used (I guess there is no way to cleanly separate parameters but i may be wrong)

tillvz|4 years ago

Hey that's very cool and works surprisingly well!

At Veezoo (http://www.veezoo.com) we have been tackling this problem for over 5 years now.

Under the hood we are using our own models. With GPT-3 we're a bit worried about the lack of fine-grained control needed for productive use-cases and obv. also lock in.

Will try out against the same dataset and see how it compares!

tluyben2|4 years ago

Nice product, will give it a spin. For the banking market. Do you have an API exposed as well to feed questions and get (json) data? Our clients would definitely need it integrated fully.

napoleond|4 years ago

Nice! Yeah I have no doubt that a specialized model could beat this general one, although I find the output from the general one to be uncanny at times. Would love to hear your expert opinion on how they compare!

cafed00d|4 years ago

Wow, this is absolutely brilliant!

How can I extend this to use other datasets? There seem to be quite a few interesting publicly available datasets out there: https://console.cloud.google.com/marketplace/browse?filter=s...

and I'm wondering if: 1. Is there a paid-for version of your app/website where I can plug in a diff dataset? 2. Have you considered sharing the source code for others to recreate and plug in diff datasets? 3. Or, :sweat_smile:, perhaps this is as simple as adding new datasets to the drop-down menu? say, finance data / Bitcoin transactions data?

Regardless, really cool app!

napoleond|4 years ago

For other public BigQuery datasets I’d certainly consider just adding them to the demo for free—which specific Bitcoin/finance datasets did you have in mind?

For private datasets, we’re looking at adding that functionality to the core Tabby service (that’s the SaaS this relates to). Please email for info!

mritchie712|4 years ago

We did a similar analysis a while back, works surprisingly well! I OpenAI increases the amount of "training data" you can send in, I think it could get really good at generating SQL.

napoleond|4 years ago

Cool! Yes, the ability to customize the model (https://openai.com/blog/customized-gpt3/) also seems like it could be really useful for this.

earleybird|4 years ago

May be some rough edges - or I have unreasonable expecations. The weather data set has 'begin' and 'end' columns which generates bad sql.

ie, "ERROR: Syntax error: Expected end of input but got keyword END at [49:3]"

napoleond|4 years ago

Yeah many rough edges indeed. The generated SQL is the plain output from GPT-3; I have not done anything to customize the model or validate syntax outside it, so the roughness is expected. No idea if folks will find value in this despite that, hence the demo.

Nice idea, but the default natural language query generated a query that didn't run. Perhaps turn down the temperature or tune other parameters. This could be better if you fine-tune it such that anyone could bring their own dataset, with GPT3 just making it available recently. My favorite recent app for no code sql query is trevor.io that has allowed me to build a dashboard so easily. I only knew basic sql query and didn't have to tamper with the actual SQL code; it was all interactive and the results is always in the correct format. Comparing to the GPT3 approach, I would say I prefer trevor over using natural language for the precision. The appeal of using GPT3 exists only if it gets high enough accuracy, imo.

i_like_apis|4 years ago

This is pretty cool.

I thought it was funny in that in the weather dataset that "NULL" comes in first for the win for some questions:

> what is the all time rainiest city? > what are the top 5 most dry states?

The query conversion is impressive!

napoleond|4 years ago

The weather dataset has a bit of an unorthodox schema IMO, which gives the model more trouble than usual. That’s kind of the point of this demo, though: to what extent is generated SQL like this useful—despite its flaws—in the context of real-world datasets? Jury is still out :)

mjirv|4 years ago

Very nice! I’ve been working on something similar recently: https://acolytehq.com.

Would be happy to chat and compare notes if you'd like!

napoleond|4 years ago

Awesome! Always happy to chat; my contact info is in my profile (and also at the bottom of the linked demo).

paulfitz|4 years ago

For google-trends it translated "Is there anything cat-related that people are excited about?" to something very reasonable that worked (answer: popcat apparently). Nice!

napoleond|4 years ago

Really? Wow, I would not have expected that to work. Might be one advantage of using this general model instead of a more specialized one.

talos2110|4 years ago

Nice!

As an interesting test case, check out the very strange and seemingly recursive query generated for “Get the top 10 authors of caching libraries, ranked by commit volume”

napoleond|4 years ago

Thanks for noting this! The functionality is definitely not perfect, and the opaque nature of the underlying model does not give much opportunity for tweaking. I suspect slightly altering your input might help drive better output.

331c8c71|4 years ago

Works unexpectedly well! As many others I am wondering how difficult/costly it'd be to have this assistant set up for another dataset.

napoleond|4 years ago

Are you looking to set it up for another public dataset or your own private one? Either way, shoot me an email (on the demo page and also in my HN profile) and I’ll see what I can do.

Great use case. Is the demo broken?

Why do programmers seem to love the preposition 'against'? 'On' would have been fine
