Roger that on the nvarchr2 or varchar2, like you I have seen the "n" data types
don't get a value printed in the trace so I figured that the data is being
interpreted as a varchar2 not an nvarchar2.
It would be interesting to see the SQL, the explain plan and the stat lines of
the SQL being run, it may well be that a data type conversion is taking place,
although it seems odd since Oracle by default always converts the SRTING type
(varchar2 in this case) to a NUMBER and not a NUMBER to a STRING. So I don't
think this is an implicit conversion. But with out the code we are guessing.

Hi,
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:
Oracle® 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.
