How to Convert Rust to SQL - Step by Step Guide

Step 1

Input Your Rust Code

Start by adding your Rust struct definitions to the converter:

•
Paste directly: Copy your Rust struct definitions and paste them into the input editor
•
Upload a file: Click "Upload" to select a .rs file from your project
•
Try the sample: Click "Sample" to load example Rust struct code
Step 2

Automatic SQL Generation

The converter automatically parses your Rust code and generates SQL statements:

•
CREATE TABLE: Generates schema definitions based on struct fields and types
•
INSERT statements: Creates data insertion queries from struct values
•
Type mapping: Converts Rust types to appropriate SQL data types
Step 3

Review Generated SQL

Review the generated SQL output with syntax highlighting:

•
Syntax highlighting: Review the SQL with proper color coding for better readability
•
Valid SQL: Output follows SQL standard syntax compatible with major databases
•
Real-time conversion: See changes instantly as you modify the Rust code
Step 4

Export Your SQL Code

Get your generated SQL ready for use:

•
Copy to clipboard: One-click copying for quick use in database tools
•
Download as .sql file: Save as a file for migrations or database seeding
•
Ready to execute: Perfect for PostgreSQL, MySQL, SQLite, and other SQL databases

Frequently Asked Questions

How does the Rust to SQL converter work?

The converter parses Rust struct definitions and maps each field to SQL column definitions. It generates both CREATE TABLE statements for schema creation and INSERT statements for data insertion, automatically converting Rust types to appropriate SQL data types.

Which databases are supported?

The generated SQL follows standard SQL syntax compatible with PostgreSQL, MySQL, SQLite, MariaDB, and other major relational databases. Type mappings are designed to work across different database systems.

How are Rust types mapped to SQL types?

String becomes VARCHAR or TEXT, integers (i32, i64) become INTEGER or BIGINT, floats become REAL or DOUBLE, bool becomes BOOLEAN, and Option types become nullable columns. The converter uses standard SQL data types for maximum compatibility.

Can I use this for database migrations?

Yes! The generated CREATE TABLE statements are perfect for database migrations. You can use the output directly in migration files for tools like Diesel, SQLx, or any other Rust database library, or in raw SQL migration scripts.

How are nested structs handled?

Nested structs can be handled in two ways: either flattened into the parent table with prefixed column names (e.g., address_city), or as separate tables with foreign key relationships. The tool provides options to customize this behavior.

Is the Rust to SQL converter free?

Yes, completely free with no limitations on usage or file size. No registration required, and you can generate unlimited SQL from your Rust structs for any database project.
