Should I use 0/1 or True/False boolean? [duplicate]

Question

0/1 can be flexible and can add options such as "2, 3, 4" in the future.

Does TINYINT in MySQL take up more space than boolean?

Personally, I use 0 and 1 for everything.

You can answer this question in the context of regular programming (or MySQL, whichever you like).

Answer 1

Any good database system worth its salt will convert boolean to and from something appropriate for the database, and using an actual boolean type makes programming against it much nicer.
