I need update all values on one table as T where there exist certain condition on other table.

I know this query is wrong but how do I get it to work in Oracle update statement if the select statement between () returns a value

update sample s set s.L_INVOICE_FLAG  = 'T' where (s.project like (select p.name from project p inner join sample s on p.name = s.project where p.closed = 'T' and p.status = 'V'))

Not sure I follow the logic but try IN.

Change:
...  where (s.project like (select p.name ...
to:
...  where (s.project in (select p.name ...

and then also remove the inner join as it won't be required
UPDATE sample s
SET s.L_INVOICE_FLAG = 'T'
WHERE s.project IN (
		SELECT p.NAME
		FROM project p
		WHERE p.closed = 'T' AND p.STATUS = 'V'
		)

... where (s.project like ...
and
... on p.name = s.project  ...
are duplicated.
So it should be like this:
update sample s set s.L_INVOICE_FLAG  = 'T' where s.project in (select p.name from project p where p.closed = 'T' and p.status = 'V')
you can not use 'like' against sub-query.
