Hello list,
This is an inventory system where some users are restricted to view only certain suppliers, those restrictions are in a table called pedusers (username,supplierallowed), there are other kind of "superuser" who are not restricted, actually I created another table for them (userexcept). To select restricted rows I use this code:
select * from prvdor where prvtiprov = 2 and prvpk in (select usr_prvdor from peduser where usr_login = 'default')
I think I would write this in a return set function instead but I would like to know others ways to write a SQL sentence to return the rows according users permission/restrictions.
Thanks in advance for your comments
