How to handle an Oracle error

Question

I want to handle an Oracle Error in my code where the "execute immediate" statement comes to play.
My code goes against several tables
ID_TABLE_08
ID_TABLE_07
ID_TABLE_06
If table does not exist in database (ie: ID_TABLE_05) I get : Oracle Error ORA-0942 table or view does not exist.
How can I capture and handle this error so
1. The code will continue to run getting the next value
2. The bad record still will get written in to a table called bad_table.
v_year := TO_CHAR (pp_eff_dtg (indx), 'yy');
BEGIN
EXECUTE IMMEDIATE
'SELECT DISTINCT ID_number
FROM ID_TABLE_'|| v_year||'
WHERE NAME = :NAME
AND EFFECTIVE_DATE = : EFFECTIVE_DATE
INTO v_ID_number
USING pp_NAME (indx),
pp_eff_dtg (indx);
GOTO END_LOOP;
EXCEPTION
WHEN NO_DATA_FOUND THEN
GOTO INSERT_ADD_RECORD;
END;
Thank you for your help!

Answer 1

if you want to handle a specific oracle error number you can also declare an exception, match that exception to the error number and handle it.
Like this (not syntax checked)
declare
  e_table_does_not_exist exception;
  pragma exception_init (-942,e_table_does_not_exist); -- I hope I got the parameters in the right order
begin
   EXECUTE IMMEDIATE('select * from ID_TABLE_'|| v_year||' where ...');
exception
   when e_table_does_not_exist then -- handle specific error
       raise_application_error(-20001,'The table ID_TABLE_'|| v_year||' could not be found. Next time enter a valid year!');
end;
