Well if I include the code all over the place in all modules then the benefit is mostly lost. The point is to make the module truly optional. > Maybe a abstract kind of iterator should be integrated to work with > both, unbuffered and buffered lists in the same way? Well if you use unbuffered queries you will just do query() and then fetchRow() in a loop and then free the result set once you are done. You can do this with buffered queries as well. But you might as well just have a method query, fetch all data you want and free the result set, which is what the query* methods do.

The point of the native class is that it doesnt do any abstraction. Any similarities are "accidental". There is no emulation. If you use this class you better know that you are only working with the correct backend. > And finally: > A "little" feature request for LOBs: Maybe it would be usefull > to have a factory for reading and writing LOBs for example > to/from files, FTP, Streams, and other stuff!? Well there is such a factory! It's the "createLob" method. However in MDB 2.x you don't need to touch it if you don't want to. You just have to pass an array to the setParam method before the insert and it creates the LOB object for you. When you fetch a LOB you just need to tell MDB which column contain LOBs and it will create the necessary instance for you. Right now you can read/write from and to variables and files. If you want more you can add new classes to the LOB.php module. Regards, Lukas
