Bind a variable in a View object

Question

i built a new ADF application and i need to use the user in the where clause of the SQL of the view objects, the applicaton users aren't database users so i can't use the 'user' variable in the SQL. i know how to get the user as above
Expression Language
<af:outputText value="#{facesContext.externalContext.userPrincipal.name}"/>
Managed / Backing Bean
ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
String userName = ectx.getUserPrincipal().getName();
System.out.println("Current user: " + userName);
ADF BC Application Module
String userName = getUserPrincipalName();
System.out.println("Current user: " + userName);
but i don't know how to use it in the SQL of the VO??
Appreciate any help

Hello,
Yes a bind variable is the correct way.
Maybe these steps will help you:
1) Create a viewobject with the bindparameter
2) On the page you need to call it, rightclick the page and select goto pagedef.
3) Select the STRUCTURE window, select BINDINGS
4) right click, Select insert inside, action
5) select the viewobject you need to query, select EXECUITEWITHPARAMS as method, it will show your bind variable, put: "#{facesContext.externalContext.userPrincipal.name}"
6) now in the STRUCTURE window, select EXECUTABLES
7) right click, select insert inside, invokeAction
8) give it some name and for BINDS select the action you just created, mose likely named executeWithParams, goto advanced properties and select refresh=always
Now each time the page is loaded the query will execute.
