README

A simple CLI tool for running SQL migrations. Drago Migration is a lightweight CLI tool built on Nette, Dibi and Symfony Console. It allows you to run SQL migrations from files or directories with checksum validation, transactional execution and database-level locking.

Requirements

• PHP >= 8.3
• Nette Framework
• Symfony Console
• dibi
• Composer

Installation

composer require drago-ex/migration

Examples

Run migrations using the Composer-installed binary:

php vendor/bin/migration db:migrate <path>

Path to a single SQL file or a directory containing multiple .sql files.

### Run all migrations in a folder
php vendor/bin/migration db:migrate migrations

### Run a single migration file
php vendor/bin/migration db:migrate migrations/001_example.sql

Export SQL Migrations

Export migration SQL files from installed Composer packages:

php vendor/bin/sql-export

By default, SQL files are copied into the migrations directory.

Use an optional target directory argument to export files elsewhere:

php vendor/bin/sql-export db
php vendor/bin/sql-export temp/sql

Existing files are skipped, so the command can be safely run repeatedly.

Automated Package Setup

Projects using drago-ex/project-tools can run package-defined migration commands through:

php vendor/bin/drago-setup

Packages expose their setup commands in composer.json under extra.drago-tools.commands. The migration package provides the migration runner; drago-setup only discovers and executes commands defined by installed packages.

Register Migration Extension in Nette

extensions:
    migration: Drago\Migration\DI\MigrationExtension(%consoleMode%)
    console: Contributte\Console\DI\ConsoleExtension(%consoleMode%)

### Symfony Console
console:
	name: Symfony Console
	version: '1.0'

Make sure the %consoleMode% parameter is available (usually already present in Nette CLI setups).

Database Setup

The migrations table is created automatically on the first migration run. The table is created from the package SQL file migrations/000_migrations.sql:

CREATE TABLE IF NOT EXISTS migrations (
    id INT AUTO_INCREMENT PRIMARY KEY,
    package VARCHAR(255) NOT NULL,
    migration_file VARCHAR(255) NOT NULL,
    checksum CHAR(40) NOT NULL,
    executed_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
    CONSTRAINT uq_migrations_package_file
        UNIQUE (package, migration_file)
)
    ENGINE = InnoDB
    DEFAULT CHARSET = utf8mb4
    COLLATE = utf8mb4_unicode_ci;

Features

• Checksum validation - detects modified migrations
• Transactional execution - safe rollback on failure
• Database locking - prevents concurrent runs
• Package-aware migrations - supports vendor-based migrations
• Automatic migrations table setup on first run
• Symfony Console integration - clean CLI output

Notes

• This package is designed for Nette Framework projects.
• The provided CLI binary expects a Nette project structure with app/Bootstrap.php.
• For non-Nette projects, a custom bootstrap script is required.
