Representing a BOOLEAN style FLAG (or simillar) in a table column? [message #370972]

Hi
I wondered if anyone could help. Is there no BOOLEAN style datatype in Oracle? I believe other RDBMS have a 'BIT' datatype .... ? Is there any way in Oracle better than using:

variable_name NUMBER(1) CHECK variable_name <=1

I'd really appreciate any input from people, thanks.

Oracle is optimized fine for text and numbers, so no performance worries. I would go with number(1) but change the check constraint to by "col_name in (0, 1)"
