What database dialects are supported for SQL export?

The designer exports SQL for PostgreSQL, MySQL/MariaDB, and SQLite. Each uses slightly different syntax for data types, auto-increment (SERIAL vs AUTO_INCREMENT vs INTEGER PRIMARY KEY), and foreign key definitions.

Can I import an existing database schema?

Yes. Paste an existing CREATE TABLE SQL script and the designer will parse it and render the visual diagram automatically — useful for visualizing and editing inherited database schemas.

What is the difference between a one-to-many and many-to-many relationship?

One-to-many: one record in table A relates to many records in table B (one customer → many orders). Many-to-many: many records in A relate to many in B (many students ↔ many courses). Many-to-many requires a junction table (enrollments) with foreign keys to both tables.

What is Visual Schema Designer?

Designing a database schema visually is far more productive than writing DDL SQL by hand. DailyDevTools' Visual Database Designer lets you create tables, define columns with types and constraints, draw relationships (one-to-one, one-to-many, many-to-many), and generate the complete CREATE TABLE SQL for PostgreSQL, MySQL, or SQLite — all in an interactive drag-and-drop canvas.

How to use Visual Schema Designer

1Click Add Table to create a new table and give it a name
2Add columns by clicking the + button on each table: set name, data type, and constraints (PK, FK, NOT NULL, UNIQUE)
3Draw relationships by dragging from a column to the primary key of another table
4Click Export SQL to generate the complete DDL script with CREATE TABLE statements and foreign key constraints
