Hi,
I am trying to call a C function from PL/SQL and I encounter
"ORA-06525 Length Mismatch for CHAR or RAW data". Following is the
information:
C function in util.dll:
INT Scramble(BYTE *input,
BYTE *key,
INT which,
BYTE *output);
I create the library and PL/SQL body using the following script:
CREATE OR REPLACE LIBRARY util
AS
'E:\Develop\tes t\util.dll';
CREATE OR REPLACE FUNCTION Scramble
(plaintext IN RAW,
key IN RAW,
which IN PLS_INTEGER,
ciphertext IN OUT RAW)
RETURN PLS_INTEGER
IS EXTERNAL
LIBRARY util
NAME "Scramble"
LANGUAGE C;
When I test the above function Scramble using the following PL/SQL, I
receive the error at the beginning of this message.
DECLARE
rvalue PLS_INTEGER;
plaintext RAW(8);
key RAW(16);
which PLS_INTEGER;
ciphertext RAW(8);
BEGIN
plaintext := '12345678';
key := '12345678123456 78';
which := 0;
-- SQL error at the following line!!!!!
-- "ORA-06525 Length Mismatch for CHAR or RAW data"
rvalue := SCRAMBLE(plaint ext,
key,
which,
ciphertext);
END;
Could anyone give me any idea what's wrong with the above code. Thank
you.
Cheers,

HY!
I´ve never tried it with byte. But with char* and string it should work.
Otherwise you can try to change the in out prefix.

Please help
I don't know if this is possible but what I would really like to do is
to use On Error Goto to capture the code that is being executed when
an error occurs.
Any help would be much appreciated.
Thanks in advance

I'm trying to figure out if there is a way to generate standard error handlers
that "know" if the calling code has an error handler in effect (On Error Goto
<label> or On Error Resume Next) before deciding how to respond. Does anyone
know if this is possible.

I use code extensively; I probably overuse it. But I've been using
error trapping very sparingly, and now I've been trapped by that.
A form that works for me on the system I'm using, apparently runs into
problems on the system where it will actually be used, and since I
used so little error-trapping it dies very ungracefully.
I will of course try to fix whatever is causing the error and add
error-trapping to the functions where the...
