Not sure what transaction is. Getting more and more familiare with sql, 
but that is new to me. I have the latest MySQL.

I can't add a column with migration, in a simple test-db, and I suspect 
it's due to an error in my syntax. Will that then stop any further 
attempts with migration? Is it this that you're referring to?

Trying to learn migrations, but not sure it is better for me as a lonely 
developer than using MySQL's Tools. One benefit I see is being able to 
dynamically modify a db for an external user.
