Code & Data Generator
How PostgreSQL column types map to their MySQL equivalents, with migration notes for each type.
| PostgreSQL Type | MySQL Equivalent | Notes |
|---|---|---|
| SERIAL | INT AUTO_INCREMENT | Add AUTO_INCREMENT to INT column |
| BIGSERIAL | BIGINT AUTO_INCREMENT | — |
| SMALLSERIAL | SMALLINT AUTO_INCREMENT | — |
| INTEGER / INT4 | INT | — |
| BIGINT / INT8 | BIGINT | — |
| SMALLINT / INT2 | SMALLINT | — |
| BOOLEAN / BOOL | TINYINT(1) | MySQL has no native BOOL; uses 0/1 |
| TEXT | LONGTEXT | MySQL TEXT is limited to 65,535 bytes |
| VARCHAR(n) | VARCHAR(n) | Same syntax; max 65,535 bytes in MySQL |
| BYTEA | BLOB | Binary data |
| TIMESTAMP | DATETIME | MySQL TIMESTAMP is UTC-only and has year-2038 limit; prefer DATETIME |
| TIMESTAMP WITH TIME ZONE | DATETIME | MySQL has no timezone-aware datetime; store UTC |
| JSONB | JSON | MySQL 5.7+; no operator support like Postgres JSONB |
| UUID | CHAR(36) | MySQL has no UUID type; use CHAR(36) or BINARY(16) |
| DOUBLE PRECISION | DOUBLE | — |
| REAL | FLOAT | — |
| NUMERIC(p,s) | DECIMAL(p,s) | — |
| SERIAL PRIMARY KEY | INT AUTO_INCREMENT PRIMARY KEY | — |

Everything you need to know about converting PostgreSQL to MySQL.
Paste your PostgreSQL CREATE TABLE statements into the SQL editor on the left. The MySQL output appears instantly on the right panel in real-time as you type.
Yes — completely. The entire conversion runs inside your browser using JavaScript. Your SQL is never sent to any server, logged, or stored anywhere. This makes it safe to use with production or confidential database schemas.
PostgreSQL, MySQL, SQLite, SQL Server, Oracle, and MariaDB DDL syntax are all supported. The parser auto-detects the dialect from your CREATE TABLE syntax automatically.
Yes! Paste multiple CREATE TABLE statements separated by semicolons and all tables will be converted simultaneously, including cross-table foreign key relationships.
Yes. NULL, NOT NULL, DEFAULT values, PRIMARY KEY, UNIQUE, and FOREIGN KEY constraints are all parsed and reflected in the MySQL output. Nullable columns are correctly typed as optional properties or nullable types.
Yes, SchemaForge is completely free with no usage limits, no account required, and no rate limits. The tool runs entirely in your browser and will always be free.
