Laravel Migration Returning Invalid SQL

问题

I am running Laravel 6.0.2 and my migration up method is as follows:

Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('first_name');
            $table->string('last_name');
            $table->string('email')->unique();
            $table->string('password');
            $table->boolean('admin')->default(false);
            $table->boolean('manager')->default(false);
            $table->rememberToken();
            $table->timestamps();
});

create table `users` (
  `id` int unsigned not null auto_increment primary key,
  `first_name` varchar(255) not null,
  `last_name` varchar(255) not null,
  `email` varchar(255) not null,
  `password` varchar(255) not null,
  `admin` tinyint(1) not null default ('0'),
  `manager` tinyint(1) not null default ('0'),
  `remember_token` varchar(100) null,
  `created_at` timestamp null,
  `updated_at` timestamp null
) default character set utf8mb4 collate 'utf8mb4_unicode_ci'

I have run that SQL on an online syntax checker and that is giving me and error on the admin tinyint(1) not null default ('0'), line.

I am not sure whether this is a Laravel 6.0.2 bug as it seemed to be working before that update.

Has anyone run into this issue and know of the fix?

回答1:

Well, this is pretty easy to fix and pretty easy to overlook. My guess is you've been looking at it for too long.

Your DEFAULTs don't need parenthesis or the quotes. The quotes are only there for strings, not ints, and the parens are only needed if it's a subquery (which isn't likely would actually work, but I haven't tried it).

回答2:

In mysql boolean type is tinyint 0 false 1 true ...

$table->boolean('admin')->default(0);
