As usual (From all your previous posts) we(I) haven't understood anything, We don't have anything except one UNFORMATTED UPDATE STATEMENT,
After 200+ messages..still you doesn't post the message with formatting...
Are you looking something like this ??
UPDATE (
SELECT *
FROM test
WHERE table_name NOT LIKE '%A%')
SET extent_management = 'Unknown'
WHERE table_name NOT LIKE '%A%';

I did not understand what you mean by update using select format but I assume you mean to use something like this
update (select col1,col2 from tbl1, tbl2 where ..) set col = col2
but bear in mind the table from where you update should be key preserved otherwise you will get ORA-01779 error
