Convert MySQL to PostgreSQL
A free online converter that translates MySQL queries into PostgreSQL. Paste your SQL, press Translate, and Query Studio rewrites the syntax that differs between the two databases — instantly, with no login and nothing stored.
MySQL → PostgreSQL example
Here is a real MySQL query and the PostgreSQL output Query Studio produces:
SELECT u.id, u.name, COUNT(o.id) AS orders
FROM users u
LEFT JOIN orders o ON o.user_id = u.id
WHERE u.created_at > '2024-01-01' AND u.active = 1
GROUP BY u.id, u.name
HAVING COUNT(o.id) > 3
ORDER BY orders DESC
LIMIT 10;SELECT
u.id,
u.name,
COUNT(o.id) AS orders
FROM
users u
LEFT JOIN orders o ON o.user_id = u.id
WHERE
u.created_at > '2024-01-01'
AND u.active = 1
GROUP BY
u.id,
u.name
HAVING
COUNT(o.id) > 3
ORDER BY
orders DESC
LIMIT
10;What changes from MySQL to PostgreSQL
- Identifier quoting is rewritten from backtick `identifiers` to double-quoted "identifiers".
- Null-handling functions such as IFNULL() are mapped to COALESCE().
- The result is re-indented and keyword-cased in PostgreSQL style so it's ready to paste and run.
