Non-deterministic System Function Suser_sname-I Think Here Is The Right Place For My Question

Hi,

I am using Sql Server 2005 as the database management and Access 2003 as the front-end. In the database, I intend to give different views of tables to different users. That's why I used suser_sname system function, which returns the windows login id and authenticates users to see different records in the same view. What I want to do in Access is, allowing some specific users to be able to do update, insert and delete operations through a form based on this view (which only depends on 1 table). However, Access tells me that "the recordset is not updateable". In order to be able to change records, I tried to create new index for the view in Sql Server, which failed giving "Sql Server, Error number:1949" and telling me that it fails since suser_sname yields non-deterministic results. The strange thing is that when I open VB Editor in Access and write a simple update code within this form, it updates both the view and the table in the database. My question is: How can I do update, delete and insert operations on the form directly? Is there a way to do the authentication without using a nondeterministic function in Sql Server or using the front-end Access 2003? Maybe a function similar to the current_user function in Access can do that, I don't know.



It's been a long question but I desperately need the answer. Any thanks will be appreciated.
