Could you please turn this into a reproduceable script? That means provide the necessary SQL and a script that can be run with only modifying the DSN. Also what version of MySQL are you running?

The next release is about 1-2 weeks away. If you want to get this issue fixed in the next release I really need a reproduceable script.

I will try to make time for this again tonight. I've been going flat out in other areas. It is still an important issue for me, so I will try to pull together a full reproducer tonight. Regards, LFaR.

Hi Lukas, Thanks again for prodding me on this. I hope I am doing everything correctly here. I am still quite the novice, so I haven't ruled out a silly error on my part. The simple script below creates a database table called 'animal'. It then demonstrates that MDB2's lastInsertID() succeeds if the new row was inserted with the query() function, though it fails if the new row as inserted with the autoExecute() function. Let me know if I can be of more help. Best regards, LFaR.

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better. Turns out this was caused by mysql_insert_id() breaking if the prepared statement that was executed to generate the ID was deallocated before. Fixed this by using SELECT LAST_INSERT_ID() instead.

I have verified this fix with your updated package from CVS. Much appreciated for the fix. All the best to you! LFaR.
