Creating a dynamic where clause

Question

hello,
I am trying to create a procedure whech needs to parse a dynamic where clause into a cursor. The problem is I do not know the number of items that the user has selected (from previous input), thus what I want to pass in is a string of variables, but I donl;t think I can do this.
Does anyone have any ideas on how I can do this?
Thanks
Bryan

an example of theh code I am trying to run is:
v_update:='UPADTE :tabnam
SET ctrecid = :ctrec';
WHERE :v_and
AND pxlrecno = :strt';
v_cursor2 := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(v_cursor2,v_update,DBMS_SQL.V7);
DBMS_SQL.BIND_VARIABLE(v_cursor2,':tabnam',tabnam);
DBMS_SQL.BIND_VARIABLE(v_cursor2,':ctrec',ctrec);
DBMS_SQL.BIND_VARIABLE(v_cursor2,':v_and',v_and);
DBMS_SQL.BIND_VARIABLE(v_cursor2,':strt',strt);
v_numrows:=DBMS_SQL.EXECUTE(v_cursor);
Where v_and is something like:
item1='TEST1' AND item2='TEST2' AND item3='TEST3'
null

SQL> EDIT update_tabnam
CREATE OR REPLACE PROCEDURE update_tabnam
(tabnam IN VARCHAR2,
ctrec IN VARCHAR2,
v_and IN VARCHAR2,
strt IN VARCHAR2)
IS
v_update VARCHAR2 (3000);
v_cursor2 INTEGER;
v_numrows INTEGER;
BEGIN
v_update := 'UPDATE ' | | tabnam
| | ' SET ctrecid = ' | | '''' | | ctrec | | ''''
| | ' WHERE ' | | v_and
| | ' AND pxlrecno = ' | | strt;
v_cursor2 := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE (v_cursor2, v_update, DBMS_SQL.V7);
v_numrows := DBMS_SQL.EXECUTE (v_cursor2);
DBMS_SQL.CLOSE_CURSOR (v_cursor2);
END update_tabnam;
SQL> START update_tabnam
Procedure created.
SQL> EXEC update_tabnam('TEST',7,'ITEM1=''TEST1'' AND ITEM2=''TEST2'' AND ITEM3=''TEST3''',1)
PL/SQL procedure successfully completed.
SQL> SELECT * FROM test;

Note: Posting on this forum causes spaces to be inserted between the concatenation symbols where they don't belong, so anywhere you see a space between | and | remove it, before saving the file and starting it to create the procedure.
