Tips for better results

  • Describe the goal, not the SQL syntax — e.g. 'find users who placed more than 3 orders'
  • Include table/column names if you know them, or paste your schema above
  • Specify filters like date ranges, status values, or thresholds
  • Mention aggregations such as COUNT, SUM, AVG when needed
  • State any ordering or limit requirements

About AI SQL Query Generator

How It Works

  • Describe your data need in plain English
  • Optionally paste your table schema for more accurate results
  • Select your SQL dialect (MySQL, PostgreSQL, SQLite, etc.)
  • The AI generates a formatted SQL query with explanation
  • Copy the query directly into your database client or code

Common Use Cases

  • Quickly prototype complex JOIN or aggregation queries
  • Learn SQL by seeing generated queries for described needs
  • Speed up report writing without memorising dialect-specific syntax
  • Generate boilerplate INSERT / UPDATE / DELETE statements
  • Translate data questions from stakeholders into runnable SQL

Frequently Asked Questions

What SQL dialects does the AI SQL Query Generator support?

The tool supports five major SQL dialects: MySQL, PostgreSQL, SQLite, SQL Server (T-SQL), and Oracle (PL/SQL). Select your dialect from the dropdown so the AI can generate syntax-correct queries tailored to your database engine.

Do I need to provide a table schema?

No — the schema field is optional. However, pasting your table definitions (e.g. users(id, name, email)) significantly improves accuracy because the AI can reference real column names and relationships instead of guessing them.

How detailed should my description be?

Be as specific as possible. Include what data you want, which tables are involved, any filtering conditions, aggregations (SUM, COUNT, AVG), and ordering or limit requirements. The more context you provide, the more accurate the generated query will be.

Can it generate complex queries with JOINs and subqueries?

Yes. The AI can produce queries that include multiple JOINs, subqueries, CTEs (Common Table Expressions), window functions, GROUP BY with HAVING clauses, and other advanced SQL constructs.

Is the generated SQL safe to run in production?

Always review AI-generated SQL before running it in production. Verify the logic matches your intent, check for potential performance issues on large tables, and test on non-production data first.

Can I generate INSERT, UPDATE, or DELETE statements?

Yes. Just describe what you need — for example 'insert a new user record' or 'update the status to inactive for all orders older than 90 days.' The AI handles all DML statement types, not just SELECT queries.

What is the maximum length for my description?

Descriptions are limited to 2,000 characters and schemas to 3,000 characters. These limits are sufficient for most use cases. For very complex requirements, consider breaking them into separate queries.

Can it generate queries that use stored procedures or functions?

The tool is optimised for standard SQL queries rather than stored procedure definitions or complex PL/SQL blocks. For straightforward function calls within a query (e.g. DATE_TRUNC, COALESCE, CASE expressions) it works well.

What if the generated query has errors or wrong column names?

If the query references columns that do not exist, paste your actual schema into the schema field and regenerate. If the logic is off, add more detail to your description.

Can I use this tool to learn SQL?

Absolutely. Each generated query comes with a plain-English explanation. You can describe a concept you want to learn — for example 'demonstrate a LEFT JOIN between customers and orders' — and study the result to understand the SQL pattern.
