Artisan 'Nothing to rollback' when there is a table already created - laravel

Question

I wanted to make a migration using php artisan migrate but I got an error:
SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' already exists
So naturally I wanted to drop my tables using php artisan migrate:rollback, but I got:
Nothing to rollback.
What the heck? It said just earlier that the users table was already created. What should I do? I can delete the table with phpmyadmin but I want to learn how to use artisan.
Thank you for your help.

Answer 1

Failing an answer to how to delete the tables with artisan when there is this problem, I will tell you how to avoid this problem in the first place. Ultimately I just deleted the tables using phpmyadmin.
I watched a tutorial on Laravel and I saw that in order to avoid the error:
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes
I had to add use Illuminate\Support\Facades\Schema; in AppServiceProvider.php and Schema::defaultStringLength(191); in the boot() function. But I thought that I could put any number in defaultStringLength(...) so I put 255, and the migration didn't work.
Do as it is told in the tutorials, write Schema::defaultStringLength(191);. Then, you can execute your migration using php artisan migrate and it should work properly.

Answer 2

In my case after defining Schema::defaultStringLength(191); in the boot() method didn't solved. Because the migrations table in the database is empty.
So the solution is open up the tinker from the composer
$ php artisan tinker
>>> Schema::drop('users')
>>> Schema::drop('password_resets')
>>> Schema::drop('orders')
>>> exit
php artisan migrate
Here is the result of the above commands executed
nishanth#localhost:~/Desktop/html/hutch$ php artisan migrate
In Connection.php line 647:

Also define the method down(), if it doesn't exist.
Otherwise, it'll show
SQLSTATE[42S02]: Base table or view not found: 1051 Unknown table 'XYZ.ABC' (SQL: drop table ABC)
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('ABC');
}

Answer 3

SOLUTION:
>> php artisan migrate:fresh
It will drop all tables and recreates all the migrations.

Answer 4

Add use Illuminate\Support\Facades\Schema; in AppServiceProvider.php and Schema::defaultStringLength(191); in the boot() function
Run php artisan migrate:fresh
Run php artisan migrate again
Solved!

Answer 5

php artisan db:wipe
It is a quick way to drop all the tables, their types and views if you’re using Laravel 6.x
Full description:
$ php artisan db:wipe {--database=} {--drop-views} {--drop-types} {--force}
database - The database connection to use
drop-views - Drop all tables and views
drop-types - Drop all tables and types (Postgres only)
force - Force the operation to run when in production
