<< Well, Stream support is faster and better isn't ? >> Better, but not necessarily faster. However, it is almost impossible to deal with table files in raw form now anyways without including the database catalog in the mix, so the streaming way is the only practical way to do this. -- Tim Young Elevate Software www.elevatesoft.com |
