mysql - 如何在原始查询 Laravel 中创建表？

Question

我正在尝试创建新的数据库，该数据库已成功创建，但该数据库中的某些表未创建。这个查询有什么问题吗？它说:

QueryException in Connection.php line 770: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'CREATE TABLE activities ( id int(10) UNSIGNED NOT NULL, ' at line 3 (SQL: CREATE DATABASE institution_70 CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE TABLE activities ( id int(10) UNSIGNED NOT NULL, name varchar(150) COLLATE utf8_unicode_ci NOT NULL, created_at timestamp NULL DEFAULT NULL, updated_at timestamp NULL DEFAULT NULL, deleted_at timestamp NULL DEFAULT NULL ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; )

DB::connection('rc')->statement("
    CREATE DATABASE institution_$institutionId CHARACTER SET utf8 COLLATE utf8_general_ci;

    CREATE TABLE `activities` (
      `id` int(10) UNSIGNED NOT NULL,
      `name` varchar(150) COLLATE utf8_unicode_ci NOT NULL,
      `created_at` timestamp NULL DEFAULT NULL,
      `updated_at` timestamp NULL DEFAULT NULL,
      `deleted_at` timestamp NULL DEFAULT NULL
    ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
    ");

删除时间戳后的NULL

   CREATE TABLE `activities` (
      `id` int(10) UNSIGNED NOT NULL,
      `name` varchar(150) COLLATE utf8_unicode_ci NOT NULL,
      `created_at` timestamp DEFAULT NULL,
      `updated_at` timestamp DEFAULT NULL,
      `deleted_at` timestamp DEFAULT NULL
    ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
