[Chicago] MeetUp

[Massimo Di Pierro]

Most of the GAE functionality is supported by the web2py ORM and  
*any* program written with web2py for GAE works on other databases  
(mysql,postgresql,sqlite, oracle (and mssq soon)). The opposite is  
not true. For example

     db(db.table.field='value').select 
(db.table.ALL,orderby=~db.tabel.field)

works everywhere including GAE but

     db((db.table.field='value')& 
(db.othertable.id==db.table.referencefield)).select 
(db.table.ALL,orderby=~db.tabel.field)

does not work on GAE because it does a join.
