DataObject tweak ok with DB and MDB2

Hi there, I want some ok especially from Alan on this, I tried using the pear db wrapper for MDB2 but sounds crazy and also didnt work entirely. This tweak makes changes to the following methods _connect find fetch fetchRow update insert joinAdd There is two method differences between DB and MDB2. These are quoteSmart -> quote modifyLimiteQuery -> setLimit the fetchmode constants in fetchRow in methods fetch and fetchRow. There was one more issue which was affectedRows and i am trying to work out an equiv for MDB2. I have also updated my MDB2 to beta3 with the BC breaks and no issues so far, I run PHP5 though. I have tweaked the code to allow to use either DB or MDB2 by checking for methods. I also noticed $db_options from the pear static method wasnt doing anything, so i am sending $db_options to the MDB2 class from a nested array called MDB2 within the DataObject array. Maybe there is a better way by using a factory loader method, but I am not very up to scratch on this way, this tweak is maybe not so efficient, but this is a huge class, there is a tonne of if statements so i doubt this will slow it down anymore. Let me know if what I have done is helpful, as it became a pain to have to rediff painfully each update having different class and constrant names, i have left the classname and constants as is, so its still DB_DataObject but it allows MDB2 to be used ;) www.electroteque.org/pear/DataObject.phps
