Problem while updating the records. IN clause no. of items

Question

We have an issue in updating a table when the inside IN more than 1000 numbers are passed ,
it throws error message - ORA-01795 : maximum nunbers of experssions in a list is 1000. Is there any workarround (wihtout using ARRAYs).
experssions list is passed from java.
update <table> c
set c.data='test'
where c.id in (123,345,.... 25,0000 records);We tried this way , it throws error.
DECLARE
txt  varchar2(32000):= <Text size 30000>
BEGIN
update <table> c
    set c.data='test'
  where c.id in (select To_number(REGEXP_SUBSTR (txt, '[^,]+', 1, level))  from dual
                     connect by level <= regexp_count(txt,',')+1
);thanks in advance..

Hi,
you can use WITH refactoring clause and UNION like shown below:
with gen1 as (select level x from dual connect by level <= 1000),
gen2 as (select level+1000 x from dual connect by level <= 1000),
gen3 as
(select * from gen1
  union
select * from gen2)
select * from dual where 1 not in (select x from gen3);Best regards,
