oacdty=01 could mean varchar2 or nvarchar2. There is a huge difference between the two as if a bind value is passed as a nvarchar2 and the column datatype is a varchar2 then a implicit conversion is done, meaning that an index will not be used.

I have found that (at least on 9i) in case of a nvarchar2 datatype the bind value was not shown in the trace file (but the value length was).

Yes a 1 is a varchar2 data type.  You can see these data types in the:

OracleŽ Call Interface Programmer's Guide, 10g Release 2 (10.2)
Part Number B14250-02

Chapter 3, Data Types, table 3-1.

What ever program is sending that in is not sending it as a number.
