Handling errors on looping through a package

Question

Here is my issue:
I am tyring to call a package in a loop to index rows into oracle text index 10g. When called by the app, sometimes its valid that data will be gone by the time its indexed and the package errors out and writes to a table my ora error of no data found.
This works fine until:
The application is calling my package and seems to have timing issues on creation of the index item compared to the call so for the interim (not permanent) I wanted to call my package and pass it every number that was in one table and missing from another.
This logic is easy and I got it to work splendidly in minutes as an print out in a cursor in a procedure I was going to call every so often with a job... but (there's always a but) it errors out with my no data found error and kills the entire loop and I don't get to finish processing the rogue numbers.
I know this is a hack... please forgive this. I just need an idea of how one might loop and call this procedure and pass it the numbers individually... not in a list like my cursor. The syntax itself I can probably slice and dice my way through its the concept I am missing...
Thanks in advance for your time and knowledge,

Answer 1

Assuming that you are calling the stored procedure and passing it values from the cursor, and that it a select statement in the stored procedure that raises no_data_found, then Justin's code should allow you to keep going with the other records from the cursor.
By "handling" the no_data_found exception within the loop (even if that handling is do nothing), it goes away and your code will continue with the next statement. As a quick demo:
SQL> SELECT * FROM t;
        ID S
         1 A
         2 B
         1 C
SQL> DECLARE
  2     l_dummy VARCHAR2(1);
  3  BEGIN
  4     FOR r IN (SELECT id, sorter FROM t
  5               ORDER BY sorter) LOOP
  6        BEGIN
  7           SELECT dummy INTO l_dummy
  8           FROM dual
  9           WHERE 1 = r.id;
10           DBMS_OUTPUT.Put_Line('Success with '||r.sorter);
11        EXCEPTION WHEN NO_DATA_FOUND THEN
12           DBMS_OUTPUT.Put_Line('No data with '||r.sorter);
13        END;
14     END LOOP;
15  END;
16  /
Success with A
No data with B
Success with C
PL/SQL procedure successfully completed.Here, my select from dual is equivalent to your procedure call.
