Oracle 9.2: Really strange problem so Please Help!

Question

Hi All,
I am having a really strange problem and I don't know why it is so. I have a simple sproc (for testing) that updates one column in a table and the where clause uses two in params and the set clause uses a local variable. I stepped through it in JDeveloper and saw the execute of the update and commit statements and in params' values and the local variable's value, but the row will not be updated! If I changed the where clause to use literal values (303 and '1045225') and the set clause to use 3, then it works. If params and a variable are used for these three values, the row does not get updated! And when I added the dbms_output.put_line to print out the param's value and the variable value, they are all there! Here is the code:
create or replace procedure sprocTestUpdate (
     Action          in varchar2 := 'FETCH',     
     p_QueueID          in number,
     StatusDesc     in varchar2 ,
     p_PK          in varchar2
as
     --- local varirables
     StatusID     pls_integer;
     MessageTypeID     pls_integer;
     EditActionID     pls_integer;
     v_QueueID     pls_integer := 0;
     --- error constants
     Source constant     varchar2(20) := 'RCSO';
     Sproc constant varchar2(50) := 'spCriMNetQueuePublish';
     --- status constants
     StatusUnprocessed constant varchar2(20) := 'UNPROCESSED';
     StatusProcessing constant varchar2(20) := 'PROCESSING';
     StatusProcessed constant varchar2(20) := 'PROCESSED';
     StatusError constant varchar2(20) := 'ERROR';
     v_errorMessage     varchar2(4000);
begin
     begin
          StatusID := fnc_getQueueStatusID (StatusDesc);
     exception
          when others then
               null;
     end;     
     ---set transaction isolation level serializable;
     if Action = 'STATUSUPDATE' then          
          update QueuePublish
          set StatusID = StatusID,
               attemptcount = attemptcount + 1
     where queueid = p_QueueID and PK = p_PK;          
          commit;
          dbms_output.put_line(to_char(StatusID) || ' For ' || to_char(QueueID));
     end if;
exception
     when others then
          rollback;
end sprocTestUpdate;
and here is the test script in SQL*Plus:
declare
     action     varchar2(30);
     QueueID number;
     StatusDesc varchar2(30);
     PK varchar2(30);
begin
     action := 'STATUSUPDATE';
     QueueID := 303;
     StatusDesc := 'PROCESSED';
     PK := '1045225';
     sprocTestUpdate(action, QueueID, StatusDesc, PK);
end;
thanks.

Ghulam, this is what I was talking about:
<<
StatusID := 3;
if Action = 'STATUSUPDATE' then
update QueuePublish
set StatusID = StatusID,
attemptcount = attemptcount + 1
where queueid = 303 and PK = '1045225';
commit;
dbms_output.put_line(to_char(StatusID) || ' For ' || to_char(QueueID));
end if;
and it won't update! but if I say set StatudID = 3 it will work!

might be better to do :
L_STATUSID := 3 ;
ste STATUS_ID = :L_STATUSID
...otherwise you are just replacing STATUSID by itself,
poor RDBMS-engine doesn't know what StatusId you are talking about
