Execute Raw DDL and Schema Commands Safely with DB::statement()

Use DB::statement() in database migrations to execute raw SQL statements for database triggers, stored procedures, and full-text indexes.

While Laravel's Schema Blueprint supports standard database types, advanced database-specific features (such as PostgreSQL full-text search dictionaries, MySQL generated columns, or custom triggers) require executing raw SQL.

DB::statement() executes raw SQL DDL statements directly against the active database connection.

Executing Raw SQL in Migrations

use Illuminate\Database\Migrations\Migration;
use Illuminate\Support\Facades\DB;

return new class extends Migration
{
    public function up(): void
    {
        // Add a PostgreSQL GIN index for fast full-text searching
        DB::statement('CREATE INDEX posts_search_vector_idx ON posts USING gin(to_tsvector(\'english\', title || \' \' || body));');
    }

    public function down(): void
    {
        DB::statement('DROP INDEX IF EXISTS posts_search_vector_idx;');
    }
};

Parameter Binding with DB::statement()

For parameterized DDL or maintenance operations:

DB::statement('ALTER TABLE users AUTO_INCREMENT = :val', ['val' => 1000]);

Summary

• Executes raw database DDL commands that Blueprint methods do not support.
• Supports parameter binding to prevent SQL injection.
• Returns a boolean indicating execution success.
