Bridging SQL DDL to Laravel Database Migrations
Migrating legacy relational databases into modern Laravel applications often begins with raw MySQL or PostgreSQL schema dumps. Writing Schema::create definitions by hand for dozens of tables is tedious and prone to typos. Converting DDL into native Laravel Blueprints ensures schema changes remain version-controlled, driver-agnostic, and testable via PHPUnit.
Fluent Column Mapping
SQL constructs like VARCHAR(150) DEFAULT NULL translate seamlessly to $table->string('col', 150)->nullable(), respecting defaults, zero-padding, lengths, and unsigned integers.
Indexes & Foreign Keys
Explicit table constraints like PRIMARY KEY, UNIQUE KEY, and index declarations map directly into Laravel's $table->index() and $table->unique() calls.
SQL Types to Laravel Blueprint Cheat Sheet
| SQL Column Type | Laravel Migration Equivalent | Typical Database Use Case |
|---|---|---|
| BIGINT UNSIGNED AUTO_INCREMENT | $table->id() | Standard auto-incrementing primary key |
| VARCHAR(255) | $table->string('col', 255) | Titles, names, slugs, emails |
| TINYINT(1) | $table->boolean('col') | Flags (is_active, verified) |
| DECIMAL(10,2) | $table->decimal('col', 10, 2) | Currency, monetary balances, ratios |
| TIMESTAMP created_at, updated_at | $table->timestamps() | Eloquent automatic record audit lifecycle |
Frequently Asked Questions
Which Laravel versions are supported by this migration converter?
The output targets Laravel 9, 10, 11, and 12+ standard anonymous migrations (return new class extends Migration) using modern $table->id() syntax and fluent modifiers.
How does it map complex SQL constraints and types?
The tokenizer parses INT, BIGINT, VARCHAR, TEXT, JSON, TIMESTAMP, ENUM, DECIMAL, and BOOLEAN, automatically cascading modifiers like ->nullable(), ->unique(), ->default(), and foreign key references.
Is my proprietary database structure uploaded to a server?
No. The entire lexical parsing and PHP code generation happen locally in your browser with JavaScript. Zero database schema data leaves your workstation.
