I played around with GPT-3 to build this demo. Select a public BigQuery dataset and describe your query in natural English, then edit the generated SQL as needed and execute it. https://app.tabbydata.com/sql-assistant-demo

I built a SQL analyst agent based on a simple idea: generating SQL is not the same as doing analysis. Most text-to-SQL tools stop at producing a query. But real analysis is iterative. You explore the schema, run queries, adjust, and refine. This project tries to model that loop instead of treating a query as the final output. I wrote about the approach, challenges, and tradeoffs here: https://raminmousavi.dev/blog/building-a-sql-analyst-agent Github repo: https://github.com/raminious/sql-analyst-ai-agent

I just finished writing my book that guides you through building your own SQL database server from scratch. The software engineering books I've enjoyed the most are the ones that let you learn through writing code and experimentation, which is why I wanted to create a practical book. More details and a preview at https://technicaldeft.com/build-a-database-server In summary: + Learn how parse and type check SQL + Execute complex queries that use JOIN and GROUP BY + Challenge yourself with suggested extensions + Comparisons with real databases including PostgreSQL, MySQL, SQLite…

hi hn, today I'm open sourcing a new SQL-like query language that's built for the web. it has dedicated syntax for request, parsers, selectors, and javascript snippets... it was built on nodejs with the incredible moo lexer and nearley parser. if you're a fan of regular expressions, do I have some code to show you! the website is mostly just a few examples and a playground where you can write & run (& share!) your own queries. there's also an introductory blog post where i try but ultimately fail to justify why this should be its own language and not a library/framework. enjoy!

Built QueryWeaver, an open-source text2SQL tool that uses a graph to create a semantic layer on top of your existing databases. When you ask "show me customers who bought product X in a certain ‘REGION’ over the last Y period of time," it knows which tables to join and how. When you follow up with "just the ones from Europe," it remembers what you were talking about. Instead of feeding the model a list of tables and columns, we feed it a graph that understands what a customer is, how it connects to orders, which products belong to a campaign, and what "active user" actually means in your…

Hey Everyone, I built https://querysimple.com, its a tool that allows you to transform data directly in the PostgreSQL with just SQL skills. - Creation of tables - Data syncs - Error and status reporting - Scheduling queries All of this is taken care by the application. You just write your select SQL queries. I would love some feedback from the community on the tool. You can watch a video demo, there is no need to signup. Of course, if you want to signup and give it a try that would be great!

I'm excited to share "take 2" of the Prela query language. After sharing the previous version here, I've received some valuable feedback, the main one being the weird unicode-based syntax throwing people off. Prela now has a more familiar SQL-like syntax while adhering to the algebraic principle, which makes the language compositional and controllable, all the while keeping the core engine under 1k lines of code. The engine has also been rewritten from Julia to Rust, resulting in both simpler code and faster performance (not just because "Rust fast Julia slow", but for some pretty deep…
