We have an application designed for an old oracle version which issues some sql which is no more supported in todays database version.
We want to use the application unchanged with a new database server.
Old Server Version: 7.3.4 (still in production...)
New Server Version: 10.2 or 11.2
The application issues an
ALTER SESSION SET OPTIMIZER_GOAL = FIRST_ROWS ;
which results in ORA-01986 and the application dies.
We would like to hide the error 01986 from the application using a trigger:
create or replace
trigger catch01986
after servererror
on schema
begin
if (ora_is_servererror (1986)) then
null; -- what to do here? we want clear the ora-01986 from the error stack
end if;
end catch01986;
How to handle the error, so that the
alter session set ... statement is just ignored and no error code is returned to the application?
I asked already some days ago in Database-General Forum, but triggers belong to PL/SQL, so i repost here.
Tnx for help in advance!
