When you want to flush or purge just a single (or a few) statement from the Shared Pool you can use the following query (all on a single line in SQL Developer e.g.):
exec for c in (select address, hash_value from v$sqlarea where sql_id='3hab0nxcfsxyj') loop sys.dbms_shared_pool.purge(c.address||','||c.hash_value,'C'); end loop; -- If and only if the first argument is a cursor address and hash-value, -- the flag parameter should be set to 'C' (or 'c').
Happy flushing!
