using ADODB db class

Not sure if this is really the right list to ask on, so please excuse me. I am trying to use the adodb db class with php4/mysql. On problem i have hit is that if i retrieve 2 tables with a join and the 2 tables both have a field of the same name, the command $result->fields("fieldname") always returns the value of the second field of that name. i could loop through the fields via index, then use fetchfield() to retrieve the name, but generically, I would also like to retrieve the table that the field is attached to. Does anyone know of a way to do this or a command that has this option? Thanks Mark
