How This PostgreSQL to MySQL Converter Works
Paste PostgreSQL SQL and this postgres to mysql converter online produces MySQL-compatible SQL instantly, no upload, no signup, no server round trip. It's a genuine convert postgresql to mysql workflow, data types, identifiers, and PostgreSQL-only syntax are all rewritten in place as you type.
Data Type and Function Mapping
This postgresql to mysql converter maps more than 25 PostgreSQL data types to their closest MySQL equivalent, JSONB and JSON both become JSON, UUID becomes CHAR(36), TIMESTAMPTZ becomes DATETIME, and BOOLEAN becomes TINYINT(1) since MySQL has no native boolean type. A serial to auto_increment converter pass handles SERIAL, BIGSERIAL, and SMALLSERIAL, each becomes the matching integer type with AUTO_INCREMENT appended, matching the closest postgres to mysql data types size for size.
Syntax Differences: Clauses, Identifiers, and Casts
As a postgresql to mysql sql converter it also handles the syntax differences beyond data types: double-quoted identifiers convert to backtick identifiers, a genuine postgres double quote to backtick pass since MySQL doesn't accept double quotes for identifiers by default, PostgreSQL-only clauses like RETURNING and DISTINCT ON are removed or rewritten, LIMIT/OFFSET/FETCH FIRST syntax is normalized, and PostgreSQL's :: cast shorthand is stripped since MySQL doesn't support it.
Limitations and What to Verify Manually
This postgresql to mysql converter free tool is built for a quick first pass on a schema exported via a pg_dump to mysql converter workflow, or migrating a handful of queries during a database switch, it's a regex-based best-effort postgresql to mysql migration tool, not a full SQL parser, so review the output rather than trusting it blindly, especially for ARRAY columns, HSTORE fields, and ENUM types, none of which have a clean, automatic MySQL equivalent and are flagged with a warning instead of silently guessed at.
