This is a section from the script, and it will simply not compile the views
after it checks if it was run or not. I would say there would be no harm in
running it twice but why would you?
However it will add another entry to the registry$history table which is
nothing but pollution. Maybe this is where the statement is comming from.
When in doubt:
It is better to run a very quick select aginst the registry$history table
(select statement is in the patch install guide so you can just cut and
paste it)
Rem =======================================================================
Rem To check if script is already applied
Rem =======================================================================
DECLARE
PATCH_ENTRY NUMBER;
BEGIN
SELECT DISTINCT COUNT(ID) INTO PATCH_ENTRY FROM registry$history where ID =
'&&PATCH_NUMBER';
if PATCH_ENTRY > 0
then
dbms_output.put_line ('viewrecomp.sql script is already applied');
RETURN;
end if;
