enum('yes', 'no') vs tinyint -- which one to use?

Question

What's the best practice for fields that hold true/false values?

Such columns can be defined as enum('yes','no') or as tinyint(1). Is one better/faster than the other?

Is it better to use enum('1','0') vs. enum('yes','no') (i.e., does it write 'yes' or 'no' as a string to every row so the database storage size gets bigger)?

Answer 1

avoid enum from this reasons

The bottom line is that ENUM has its place, but should be used sparingly. The model should enforce the constraints, not the database; the model should handle interpreting raw data into useful information for your views, not the database.
