I find it hard to understand why it's advantageous that column names are NOT case sensitive, while field content is. Youhave a *lot* more control over the database columns than you do over the content that goes into the fields. In my opinion,allowing someone to refer to a column as first_name, First_Name, or FIRST_NAME just encourages bad programming. -- Jordan Reiter mailto:jordan@breezing.com Breezing.com http://breezing.com 1106 West Main St phone:434.295.2050 Charlottesville, VA 22903 fax:603.843.6931
