Not sure about the other questions but in regards to changing the actual table structure. If you're dropping columns you'd first make the changes to your code base so that it no longer relies on those columns. If you have long running queries you'd just have to wait till the old ones using those columns are finished and then you could change the DB. And you'd do it in just the opposite order when you wanted to add a column. |
