Code & Data Generator
How MySQL column types map to their SQL Server equivalents, with migration notes for each type.

| INT AUTO_INCREMENT | INT IDENTITY(1,1) | — |
| BIGINT AUTO_INCREMENT | BIGINT IDENTITY(1,1) | — |
| TINYINT(1) | BIT | SQL Server BIT for boolean |
| TINYINT | TINYINT | Same name; SQL Server TINYINT is 0–255 (unsigned) |
| DATETIME | DATETIME2 | DATETIME2 has higher precision |
| TIMESTAMP | DATETIME2 | Note: SQL Server TIMESTAMP is a different, binary type |
| TEXT / LONGTEXT | NVARCHAR(MAX) | Unicode max-length string |
| VARCHAR(n) | NVARCHAR(n) | Use NVARCHAR for Unicode |
| JSON | NVARCHAR(MAX) | SQL Server 2016+ has JSON functions on NVARCHAR |
| FLOAT | REAL | — |
| DOUBLE | FLOAT | SQL Server FLOAT is 64-bit |
| DECIMAL(p,s) | DECIMAL(p,s) | Same syntax |
| BLOB | VARBINARY(MAX) | — |
| ENUM('a','b') | NVARCHAR(n) | Add CHECK constraint: CHECK(col IN ('a','b')) |
Everything you need to know about converting MySQL to SQL Server.
Paste your MySQL CREATE TABLE statements into the SQL editor on the left. The SQL Server 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 SQL Server output. Nullable columns are correctly typed as optional properties or nullable types.
