Print message in function name not present

Question

I have to execute a function from a table . It is like
cursor c1 is select fun_name from config_Table loop
v_format_sql := 'select '||c1.fun_name|| ' from dual ';
execute immediate v_format_sql into format_count;
end loop;
But if the function in the config_Table is not there or the function name is wrong it exits from the program
Please help me to print the text "function name wrong" if the function name does not exists in the database.

Hi,
You can do it like this:
SELECT COUNT(*) INTO v_func_count FROM user_objects
WHERE OBJECT_TYPE='FUNCTION' AND STATUS='VALID'
AND object_name = TO_UPPER(c1.fun_name);
IF v_func_count = 0 THEN
-- Function does not exist or not in valid state.
END IF;
