Frequently Asked Questions

Everything you need to know about converting MariaDB to SQL Server.

How do I convert MariaDB to SQL Server?

Paste your MariaDB 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.

Is my SQL schema data private?

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.

Which SQL dialects are supported?

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.

Can I convert multiple tables at once?

Yes! Paste multiple CREATE TABLE statements separated by semicolons and all tables will be converted simultaneously, including cross-table foreign key relationships.

Does this tool support nullable columns and constraints?

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.

Is SchemaForge free to use?

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.
