SQL Query Generator - Free Online AI Business Intelligence Tool

Translate plain English into executable SQL across five dialects. Describe totals, averages, top-N rankings, or trends, and get a ready-to-run query with JOINs and GROUP BY. Paste your table schema for column-accurate output. Choose Standard, Postgres, MySQL, BigQuery, or Snowflake. A rule engine covers common patterns offline; add an AI provider for complex queries. Results include syntax highlighting and a step-by-step walkthrough.

How to Use

1. Type your data question in the request box, e.g. 'total sales per region last quarter'.
2. Toggle on schema context and list your tables as table_name(col1, col2) for column-accurate SQL.
3. Select a dialect chip and optionally override the query kind (count, trend, top-N, compare).
4. Click Generate SQL, then copy the highlighted query or read the plain-English walkthrough below.

Frequently Asked Questions

Can I use this tool without an API key?

Yes. The built-in rule engine recognizes common patterns like counts, averages, and top-N queries locally. Add an AI provider key for schema-aware or more complex query generation.

Which database dialects does it support?

Standard SQL, PostgreSQL, MySQL, BigQuery, and Snowflake. Pick the matching chip before generating so syntax like date functions and string literals are dialect-correct.

How does the schema context improve results?

Paste your table definitions in the format table_name(col1, col2). The generator maps your real column names into the output, avoiding generic guesses like 'id' or 'name'.

What happens if I describe an ambiguous query?

The tool returns its best interpretation with a complexity tag. You can refine the description, adjust the query kind dropdown, or add schema context to narrow the result.
