Is there any other way of doing this

Hi,
The IN operator can handle up to 1000 items before you have to do anything special, so there's no problem with:
Update  table
set     status = 's'
where   id in ('A001', 'A002'. 'A003', ..., 'A300');Are all the ID's in a table, where they can be queried?
If so, you can use the IN operator with a sub-query:
Update  table
set     status = 's'
where   id in (
                  SELECT  id_column
                  FROM    table_2
                  WHERE   ...
              );Are the 300 ids in a flat file somewhere? You might be able to make a SQL*Plus sub-script out of it, or read it as an external table.
