问题 I built in Apex a D3 force graph basically like http://bl.ocks.org/mbostock/1093130 or http://bl.ocks.org/mbostock/4062045. The difference is, that I pull my data with an Application Process from a address table from the database. It works just fine. The colors of the nodes are defined by the address type (like Contact, Payment Office, Licensees, ...).

问题 I wanted to know, if there is a way to just get the Windows username with some kind of function, ... in Oracle APEX 4.2 an populate it a Display Only element in an application page. I don't want to do a login authentification, I just want to get the username.

问题 Is it possible to reference a LOV in plsql? I need to get the display value from a static LOV from PLSQL to use as a filter on an interactive report.
