Does the demo modify my database?

No. The demo generates and executes only a single SELECT query with a forced LIMIT and SQL-injection filters.

Do I need a schema.json file?

Yes — it maps table and column names. You can generate it in 3 steps: https://aisql.pl/en/schema-to-json.html and upload at https://aisql.pl/en/schema-query.html.

Demo: Generate SQL queries from a JSON Schema

Type your request in natural language — AI-SQL-Chat will build a single, safe SELECT with validation and a limit. You can paste your database schema directly on the Paste Schema page or use a previously generated schema.json (you can generate it in 3 steps).

How it works

On this page, in the field “Ask a question about your data”, write a request in natural language — the AI will convert it into an SQL query. You can either display the generated query or view its result as a table.

The demo database contains data about smart-home modules — including object type (house/apartment), surface area, list of modules (e.g. shutter controller, lighting, RGB), and cities.

Example queries:

show 5 best-selling modules in Warsaw with prices
show number of sold modules grouped by house/apartment with total pricing
show valuation of modules grouped by home surface area

Ask a question about your data

Write in natural language — we will generate one safe SELECT.

Natural language to SQL generator — convert descriptions into SELECT

AI-SQL-Chat acts as a natural-language SQL generator: you type a sentence in English, and the tool builds a single safe SELECT query based on your schema.json. Thanks to type validation and column-name matching, the output is ready to run.

Our description → SELECT converter works in read-only mode (no DDL/DML), enforces LIMIT, and blocks risky SQL constructs. You can paste your schema directly on the page Paste schema — just copy the table/column structure following the short guide at Copy schema guide. If you need to prepare a schema, see “How to create schema.json”, then upload it at “Upload schema”.

This solution speeds up ad-hoc analytics and improves collaboration between business and IT — from sales queries to quick reports and hypothesis testing. See how your description becomes a working SQL query.
