SchemaInterface#

Meritum\Migrations\SchemaInterface

Provides DDL operations over the write connection. Injected by the migrator into every up() and down() call. The concrete implementation selects SQL generation strategy based on DB_DRIVER.

Methods#

public function create(string $table, callable $callback): void;

Creates a new table. The callback receives a Blueprint to define columns and indexes:

$schema->create('users', function (Blueprint $blueprint) {
    $blueprint->uuid('id')->unique()->primary();
    $blueprint->string('email')->unique();
    $blueprint->timestamps();
});

public function alter(string $table, callable $callback): void;

Modifies an existing table. The callback receives a Blueprint:

$schema->alter('users', function (Blueprint $blueprint) {
    $blueprint->string('name');
});

public function drop(string $table): void;

Drops the table unconditionally.

public function dropIfExists(string $table): void;

Drops the table only if it exists. Safe to use in down() methods.

public function tableExists(string $table): bool;

Returns true if the table exists in the current database. Useful for conditional logic inside migrations.
