Some way of accessing the most recently-inserted row would be very useful.  This could be done either by an odbc version of mysql_insert_id(), or (preferably) odbc_exec() returning a pointer to the newly-inserted row so that odbc_fetch_row() and odbc_fetch_into() can retrieve the data.

I need this because I need to access any identity fields (the closest mysql equivalent is auto_increment) that were created during an insert since I tend to use these as keys and have foreign keys in other tables pointing to them.

The 2nd way is preferable because it ensures that a very busy SQL server will not return any inserts that may have been done in between the insert command and the odbc_insert_id() command.  (Even if they're back-to-back, you may still have an insert sneak in between if the server is constantly being accessed.)
