From my question on StackOverflow (CC BY-SA 3.0):

I know about the boolean column type, but is there a boolean literal in SQLite? In other languages, this might be true or false. Obviously, I can use `` and 1, but I tend to avoid so-called “magic numbers” where possible.

From this list, it seems like it might exist in other SQL implementations, but not SQLite. (I’m using SQLite 3.6.10, for what it’s worth.)
