Convert PostgreSQL to MySQL
A free online converter that translates PostgreSQL queries into MySQL. Paste your SQL, press Translate, and Query Studio rewrites the syntax that differs between the two databases — instantly, with no login and nothing stored.
PostgreSQL → MySQL example
Here is a real PostgreSQL query and the MySQL 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 = TRUE
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 = TRUE
GROUP BY
u.id,
u.name
HAVING
COUNT(o.id) > 3
ORDER BY
orders DESC
LIMIT

- Identifier quoting is rewritten from double-quoted "identifiers" to backtick `identifiers`.
- Null-handling functions such as COALESCE() are mapped to IFNULL().
- The result is re-indented and keyword-cased in MySQL style so it's ready to paste and run.
How to convert PostgreSQL to MySQL
