FAQ
What SQL dialects are supported?
The parser supports PostgreSQL, MySQL, and SQLite CREATE TABLE statements. It automatically detects primary keys, foreign keys, unique constraints, and NOT NULL constraints from your SQL definitions.
Can I edit the diagram after generation?
Yes! The diagram is fully interactive. You can drag tables to reposition them, zoom in/out, toggle between horizontal and vertical layouts, and use the search function to highlight specific tables or columns.
What export formats are available?
You can export your ER diagram as PNG (high-resolution image) or SVG (scalable vector graphic). Both formats are perfect for documentation, presentations, or embedding in wikis and README files.
