Yes, that would explain the difference entirely. _at_myID is a parameter that stands for an argument that only exists in the connection to your application so a view using it could only exist in the connection to your application. But views necessarily persist outside the scope of a connection. User() is intrinsic to the dbms and is always available. Received on Fri May 29 2009 - 20:08:13 CEST
