You want to "undo" your last database migration.
php artisan migrate:rollback command.
$ php artisan migrate:rollback
The command will list the migrations which have been undone.
To see what rollback will do, use the
$ php artisan migrate:rollback --pretend
You can also specify a database connection other than the default one.
$ php artisan migrate:rollback --pretend --database=other-one
This command will undo the last "set" of migrations.
If the previous time you ran
php artisan migrate ended up performing three different migrations, then
php artisan migrate:rollback will undo those three migrations.
This encourages small, incremental changes to your database.
