MDB2 fetchRow fails silently when an exception occurs when getting a row
How can I determine that a PL/SQL exception occurred when calling MDB2 fetchRow?
For example, I'll create a table called test_table with ids from 1 through 10000, as well as a PL/SQL function called make_error that just raises an error occasionally. Perhaps on the thousandth row fetched, for example.
create table test_table (id NUMBER); / DECLARE j NUMBER (10); BEGIN FOR j IN 1 .. 10000 LOOP INSERT INTO test_table VALUES (j); END LOOP; END; / create or replace function make_error(i_num IN NUMBER) RETURN NUMBER AS test_exception EXCEPTION; BEGIN IF (i_num MOD 1000) = 999 THEN RAISE test_exception; END IF; RETURN i_num; END; /
I do all of the MDB2 setup then fetch rows with something like this:
$sql = "select make_error(id) from test_table"; $results= $db->query($sql); while ($row = ($results->fetchRow(MDB2_FETCHMODE_ASSOC))) { $count++; print_r($row); } echo " COUNT IS $count ";
It doesn't fetch all 10000 rows. It just fails silently around fetching row 500. If I didn't know, I would think that this is all of the rows in the result set.

I did a quick experiment with try/catch; the catch wasn't executed.
Did you debug through MDB2/Driver/oci8.php to see if fetchRow() is propagating the error?
