SQL Query Generator | Write SQL from Plain English

Describe the result you want in plain English. AI2SQL writes the SQL, in the dialect you are actually using.

What the generator does

Plain English in, SQL out

Type “monthly revenue by product category for the last quarter” and get a query you can run, not a template you have to finish.

The right dialect

The same request produces different SQL in MySQL, PostgreSQL, SQL Server, Oracle, Snowflake and BigQuery. Pick your dialect and the generator follows its syntax, functions and date handling.

Works against your own tables

Paste your schema or connect a database, and column names come from your data rather than from guesses.

Explain, fix and optimize

Generation is the start. Paste a query that errors and get the fix. Paste a slow one and get an indexed rewrite with the reasoning.

Example

What you type

customers who ordered more than three times last month, with their total spend

MySQL

SELECT c.customer_id,
       c.name,
       COUNT(o.order_id)  AS order_count,
       SUM(o.total)       AS total_spend
FROM customers c
JOIN orders o ON o.customer_id = c.customer_id
WHERE o.order_date >= DATE_SUB(CURDATE(), INTERVAL 1 MONTH)
GROUP BY c.customer_id, c.name
HAVING COUNT(o.order_id) > 3
ORDER BY total_spend DESC;

PostgreSQL

SELECT c.customer_id,
       c.name,
       COUNT(o.order_id)  AS order_count,
       SUM(o.total)       AS total_spend
FROM customers c
JOIN orders o ON o.customer_id = c.customer_id
WHERE o.order_date >= CURRENT_DATE - INTERVAL '1 month'
GROUP BY c.customer_id, c.name
HAVING COUNT(o.order_id) > 3
ORDER BY total_spend DESC;

The date function changes, the interval syntax changes, and the generator handles both rather than making you translate.

How it works

Describe it. Write the question the way you would say it to a colleague.
Give it context. Paste a schema, import a .sql file, or connect a database so the query uses real column names.
Read the query. You get the SQL plus a short explanation of what each part does.
Run or refine. Run it against a connected database, or ask for a change in plain English.

Who uses it

Analysts who know what they want but not the exact window function syntax.
Developers moving between dialects and tired of translating date and string functions. See SQL query generators for developers.
Business users who need a number without filing a ticket. See SQL query generator for business users.
People learning SQL, who get a working query and an explanation of why it is written that way.

Supported databases

MySQL, PostgreSQL, SQL Server, Oracle, SQLite, MariaDB, Snowflake, BigQuery, Redshift, ClickHouse and more.

Frequently asked questions

Is the SQL query generator free?

Yes. The free plan generates queries with a monthly allowance and no credit card. Paid plans raise the limits and add database connections.

Do I need to know SQL?

No. Describing the result in plain English is enough. The explanation that comes with each query is also how a lot of people learn the syntax.

Will it work with my schema?

Yes. Paste your CREATE TABLE statements, import a .sql file, or connect the database directly. Without a schema the generator uses sensible table names you can rename.

Can it fix a query I already have?

Yes. Paste a query that throws an error and the generator returns a corrected version with the cause. The same applies to slow queries.

Which dialect does it default to?

PostgreSQL, unless you pick another. The dialect selector changes the generated syntax, not just the label.
