MySQL SQL Query 0 or 1

I have a very simple question. I have an SQL query that looks like this:

CREATE TABLE `users` (
    [...]
    `开发者_运维百科ABC` BIT()
    [...]
)

I want ABC to be either 0 or 1I am just wondering, is this the correct way to do it?

Drop the ():

CREATE TABLE `users` (
    [...]
    `ABC` BIT, 
    [...]
)

Like most people, I usually pick TINYINT(1) over BIT, but I think this is fine.

The issue with MySQL is that it doesn't have a real Boolean data type, and neither TINYINT nor BIT can represent a column that holds exactly two non-NULL values of 0 and 1 (they have different ranges of values). The only way is to emulate it with a really small numeric column and pray nobody sneaks in non-zero-or-one values...

Bit has some oddities that go along with it in new version of MySQL. I'd suggest using a bool or tinyint(1).
