Alter MySQL table to add comments on columns

Question

I have been checking the MySQL Documentation for ALTER TABLE and it does not seem to include a way to add or modify a comment to a column. How can I do this?

Answer 1

As per the documentation you can add comments only at the time of creating table. So it is must to have table definition. One way to automate it using the script to read the definition and update your comments.
