I really need these joins to filter tables instead of join all and then make a filter with WHERE (spend a long time).
I only need these 2 fields. My query works great with db.executesql but I'm not working with dal optimizations, like table record versioning, and need to do some where statment by myself (is_active). It's a DAL bug? I'm using web2py 2.7.2 2013/10/30 Massimo Di Pierro <massimo.dipie...@gmail.com> > What fields do you need to select.
