How to run Laravel's artisan migrate one step at a time?

I already read Running one specific laravel 4 migration (single file) but this doesn't give me the answer.

I want to know whether there is a way to run the command so that it just executes the next, and just this one migration.

I have got 10 files in my Migrate-Folder. 7 of them are migrated already. Now I found that while I created the 3 new ones and run the command, they are all executed.

The problem is that in the database 'select * from migrations' they show up in one batch and not in separate ones. This means that if I just want to rollback one step, we are back to step 7 and not 9 - what I want.

This is confusing sometimes as I want to rollback one step at a time and not rollback all the steps of one batch.

I know I could move the files in another folder and just leave one to run migrate. Then move the next one and migrate again but this is very inconvenient - what happens if by accident i move and migrate step 10 before step 9.

Anybody knows an answer to this?

I don't know of a way to migrate forward one at a time. But you can roll migrations back one at a time like this:

php artisan migrate:rollback --step=1

In laravel 5.4 you can: php artisan migrate --step

When you execute the command like this you can roll-back every migration individually afterwards by using the default "php artisan migrate:rollback" without specifying how many steps to rollback.

A bit of a hack, but you could run artisan migrate to run all the migrations, then the following SQL commands to make it look like the migrations were run one at a time:

SET @a = 0;  
UPDATE migrations SET batch = @a:=@a+1;

That will change the batch column to 1, 2, 3, 4 .. etc. Add a WHERE batch>=... condition on there (and update the initial value of @a) to only affect certain migrations.

Then you can artisan migrate:rollback as much as is required.

It's not enormously ideal, but after running them you can adjust the batch values on each migration in the database table to be separate numbers. php artisan migrate:rollback takes the MAX() batch value and rolls all of its migrations back.
