Question

There are spid function in sql server. Is it possible to get value of that session as well as other values like loginname with LINQ?

Answer 1

This should work (comes from http://msdn.microsoft.com/en-us/library/ms189535.aspx)

SELECT @@SPID AS 'ID', SYSTEM_USER AS 'Login Name', USER AS 'User Name'

Something along the lines of this should work with linq, provided you have the proper object setup to take the incoming data (this is not exact as I am not that familiar with SPID and have not tested this)

public class systemData
{
  int spid;
  string loginname;
  string username;
}
IEnumerable<systemData> results = db.ExecuteQuery<systemData>("SELECT @@SPID AS 'ID', SYSTEM_USER AS 'Login Name', USER AS 'User Name'");
