body: <p>I am using Flask and SQLAlchemy in a serverless function, which I don't have access to the command line. And there are times that I want to change the tables. Basically I want to automatically <strong>create new tables</strong> (already done by <code>create_all</code>) <strong>and columns</strong>, and <strong>change column</strong> (e.g. longer string).</p>
  <p>How to migrate SQLAlchemy database without generating migration script in the command line? It will be better if I can review the tasks (e.g. [add column A, drop table B]) to be done.</p>
