Frequently Asked Questions
What database systems are supported?
Export SQL for MySQL, PostgreSQL, SQLite, SQL Server, and Oracle. Each export uses the appropriate syntax and data types for the target database system.
Can I import an existing schema?
Yes! Paste existing CREATE TABLE statements, and the tool will parse them into a visual diagram. This is great for documenting and understanding existing databases.
How do I create a many-to-many relationship?
Create a junction table with foreign keys to both related tables. The tool helps you set this up correctly with proper constraints and indexes.
