Answer 1

In my case, i faced the problem while creating table from phpmyadmin. For id column i choose the primary option from index dropdown and filled the size 10.

If you're using phpmyadmin, to solve this problem change the index dropdown option again, after reselecting the primary option again it'll ask you the size, leave it blank and you're done.
