orderby can accept multiple fields by concatenating them with a "|". See the official web2py docs:

However when I used this code:

db(db.my_table.id == user_id).select(orderby=~db.my_table.isCurrent | db.my_table.endYear | db.my_table.endMonth)

The return sorted the records based on isCurrent column only. The rest of the fields were ignored.

This code worked though:

db(db.my_table.id == user_id).select(orderby="my_table.isCurrent DESC, my_table.endYear DESC, my_table.endMonth DESC")

Your query should be like db(db.my_table.id == user_id).select(orderby=~db.my_table.isCurrent | ~db.my_table.endYear | ~db.my_table.endMonth)

Tip: If you want to see the generated sql use _select db(db.my_table.id == user_id)._select(orderby=~db.my_table.isCurrent | ~db.my_table.endYear | ~db.my_table.endMonth) before run the code properly.

I see. Thanks for clarifying that. I suppose a similar example would be useful for the official docs to devoid confusion.
