That particular post ends with a wish-list of items so it's the most similar to the OP. But there are others on the site that I quite enjoy (click on the home icon and search "SQL" on the page).
My personal take is that SQL will continue to reign for a long time because of the how monumental the task of replacing it is due to the inherent complexity of databases. LLMs make this worse because they're really good at translating prose to SQL. Now that it matters less how annoying SQL is to programmers, SQL will become more like assembly over time: something mostly computers write because it's complicated for humans to deal with directly. This is deeply ironic given that SQL was ostensibly designed to read like prose, i.e. to be easy for humans.
Rawdogging SQL when you're not a seasoned DB administrator basically makes an arcane art look occult.
Most people reach out towards an ORM or query building engine and otherwise don't really go far beyond the basic CRUD, joins, and some simple aggregations with groups. Since they try to be DB agnostic you'll rarely get an adaptor over CTEs or window functions or partitioning.
An LLM is great at exposing what a database is capable of doing with SQL and might even manage to navigate the most poorly designed of schemas. And it might even manage to design one to an acceptable standard if it has enough domain knowledge in its context.
LLMs are also very good at writing code for newly invented languages, especially if they can execute it and iterate. I strongly believe the barrier to switch languages is lowered in a post LLM world.
Ten years ago I was at a startup where we used Datomic, and it was okay, but six months in the sales team was like “ok how do I run SQL queries so I can triage leads”. We had no answer of course.
Today it would simply be: type what you want in natural language and we’ll generate the query with Claude.
I just tried one representative query from that startup against a hypothetical datalog query tool in Rust and it did just fine.
SQL is what it is today because it is battle tested and has to handles a very hard problem of handling arbitrary concurrent reads/writes, so the likely scenario is that trying to replace general SQL wholesale will just end up making a worse, less tested version of SQL that developers are less familiar with. So, I think the best query language is probably whatever query feature that's already in your backend language, LINQ for C# for example. The only room for an SQL replacement in my opinion is if you are willing to trade flexibility for speed a la TigerBeetle.
The good thing about having built your own programming language via LLM nowadays is that you don't really have to speculate about a theoretical language when you can just have Codex/Claude implement it and try it out for yourself. I did it yesterday when I wanted to try out this theoretical high-performance database architecture that I had in mind and just added query functionalities to the language I already have.
If anyone is interested about the results, the default naive mode for this new database is ~0.2x the speed of concurrent durable mutation workloads, but if you specialize it to the particular application, you can get ridiculous 50-100x performance increases on filters and maps at the cost of flexibility and more upfront design. Experimental results are promising, definitely not production ready though.
The implementations are not high performance, but if you can fit everything in memory or you can organize your data and integrate it through external queries, you should get something workable for a lot of use cases.
I did not set out to replace SQL, and while I don't mind adoption, that is not why I am sharing it here. The open sourcing was motivated by making datalog more widely known. I did some research and found out that I needed a datalog implementation with particular characteristics, I for sure knew I didn't want to use SQL for what I needed.
There are structured types and recursion and being able to name predicates and compose queries... Mangle has some users and there is a few application that take advantage of the queries-as-logic-programming approach.
I think an insight one can draw in this discussion that a query language and the system (DBMS implementation) that it is part of can hardly be separated when it comes to the inevitable performance requirements one has.
As a meta comment, I can handle code blocks without syntax highlighting, and I can handle code blocks that wrap. But both together with long comments just turn into line noise. There's no longer any useful visual signal for how to read them. On my phone the code blocks are simply impossible to meaningfully parse.
this is exactly why i built Rad: a relational db with an IR as its public interface, so you can experiment with interesting query languages against a solid foundation and a real planner without needing to compile-up to sql (radengine.dev)
The problem with alternative query languages is that the people who have the most knowledge about creating queries and of the relational domains underlying their businesses are all experts in SQL. Introducing something else, then, means your most natural user base must migrate away from something they understand how to use well, and that's a hard sell.
So, until the ultimate query language is developed, I'll take SQL with pipes. It's an easy sell and good enough to eliminate 90% of my gripes about SQL.
This is exactly the same problem facing people trying to develop new music notations. In order to grasp the domain enough, they have to be experts in the existing music notation, and once you're an expert in it, the motivation to create something new goes away. From what I've seen, the people who want a new music notation are mostly people uncomfortable with sight reading.
Experts have been criticizing SQL since it was a proprietary IBM language. Take this typewritten rant from 1983 [0] as an example. And we've had better query languages for just as long, e.g. datalog. People really love SQL though, which I can only assume is because the vast majority of usecases are slight variations on SELECT * FROM table.
For example, Elastic.
Much extra learning curve for little obvious gain.
I like to say, with zero research basis, that the New Shiny has to be an order of magnitude better than the Old Thing for people to say "Oh yeah, I gotta have that."
This would have been interesting about a decade ago, but today AIs all know SQL, and I haven't written it myself in a while.
Since it seems like the quantity of training data dominates AI performance, and AI doesn't yet internalize experience with new tools, it seems like a bad idea to stray from the training set.
Without repeatable benchmarks, it feels like obsessing over a language's syntax and semantics feels a little like debating whether you write assembly using AT&T or Intel syntax.
The difference is that the bulk of what an AI knows is baked in when it's trained, at least for now. There's no way for it to learn a language and improve with it.
Can someone explain to me why SQL error messages are so bad? I routinely have some monster query where the message is effectively, "Illegal syntax somewhere, dufus".
I'd guess people just haven't put much effort into it. Lots of programming language compilers have absolutely terrible error messages. In SQL its usually just one line, so "somewhere" isn't that big a place.
A long time ago, I had to write SQL parsers (for 3 of the most popular DBs at the time). It is a surprisingly difficult language to parse and disambiguate - particularly when having to deal with the warts of its variants. Sure it's not quite C++ but it's was easily the most annoying parser work I ever had to do. And in my experience, the trickier it is to parse a particular language, the more difficult it is to provide feedback to users in the form of helpful parse errors.
This is true, but the observation is still salient. There does seem to be some correspondence between languages with inherent friction and parsers that aren’t interested in being helpful. E.g. sometimes a user base just collectively decides they’re ok with some level of pain.
What benchmarks did they use? It seems like on larger tasks, having the LLM be familiar with the language through a large volume of training data will compactness and tenseness.
that is a pretty difficult place to apply leverage. if you don't support SQL you're at a big competitive disadvantage. because its a weird design with lots of sharp edges that's going to take a lot of your time - customers are going to be unhappy that you don't support the knobs and frills from their existing environment.
so you can certainly float an alternate QL on top of the same base, but its going to be hard to drive uptake. you can translate SQL to your internal variant, but oddities like group by are going to twist your internal model.
at this point I think its more interesting to start to deconstruct these large software systems like OSes and databases and move the composition of systems down a step.
Some overlap here with some of my favorite essays on why SQL is lacking:

doesnt meant the syntax isnt a pile of dog farts
I would be genuinely curious what the OP other and folks here think of Mangle Datalog in this context. The go implementation is here: https://codeberg.org/TauCeti/mangle-go and the Rust implementation is here: https://codeberg.org/TauCeti/mangle-rs
The implementations are not high performance, but if you can fit everything in memory or you can organize your data and integrate it through external queries, you should get something workable for a lot of use cases.

This sounds like a proper of the parser, rather than of the language

I wan't easier ways to work with nested structures, like relationships. All this flat table structure is a pain.
This is an ultra compact relational query language designed for LLMs. https://memelang.net/11/
What benchmarks did they use? It seems like on larger tasks, having the LLM be familiar with the language through a large volume of training data will compactness and tenseness.

Check out CodeQL, it's a modern relational query language based on Datalog.
Why don't we have APL as the language here?
Database engineers have to be the change they want to see and add support for newer query languages.
The early-2ks crop of NoSQL solutions have all got SQL baked in now, haven't they?
Maybe when they've achieved wide adoption for a better language than SQL, they can work on getting rid of qwerty keyboards...
