Comments on: ColdFusion to Oracle via a Boolean

In a PL/SQL block, whenever a variable may have one of two values like true or false, yes or no, 0 or 1, it is only logical to declare the variable as a boolean, and that's when I use boolean. However, I do not remember using boolean as the datatype of IN, OUT or INOUT parameters of any of my procedures or functions.

You're right, SQL cannot handle boolean because boolean is not a native SQL datatype; boolean is a PL/SQL datatype.

Just curious, how often do you use the boolean datatype? When I have attempted to use it, I’ve always had to revert to a varchar2 flag, because it could not be handled in SQL, in the case of functions, or the application language did not support booleans.

I tested it with cf_sql_bit as well. Still gave me the same error "...wrong number or types of arguments...".

Looking at this documentation page, I found nothing to suggest that there is an equivalent to Oracle's boolean data type in ColdFusion. But, looks like there is for Informix and MSSQL.
