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.

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.

Still gave me the same error "...wrong number or types of arguments...". Looking at [this documentation page](http://livedocs.macromedia.com/coldfusion/7/htmldocs/00000317.htm), 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. I tested it with `cf_sql_bit` as well. Still gave me the same error “…wrong number or types of arguments…”.
