ADF BC connection to SQL Server with parameterized variable for View Object

Question

Hi everyone
I'm developing a BPM Application using Oracle BPM 11.1.1.5.0 and JDeveloper 11.1.1.5.0
Following the thread from the link below, since this is a new topic, I decided to open a new thread.
Re: ADF method call to fetch data from DB before the initiator page loads
what I'm trying to do is to get a record from a database and show it to the user on the initiator UI using ADF BC and not the Database Adapter.
I have been able to work with ADF BC and View Objects to get all the rows and show them to the user in a table.
However, when I try to run the same query in the parameterized form to just return a single row, I hit a wall.
In short, My problem is like this:
I have an Application Module which has an entity object and a view object.
My database is SQL Server 2008.
when I try to create a new read only view object to return a single row I face the problem.
The query I have in the query section of my View Object is like this:
select *
from dbo.Employee
where EmployeeCode= 99which works fine.
However when I define a bind variable, input_code for example, and change the query to the following it won't validate.
select *
from dbo.Employee
where EmployeeCode= :input_codeIt just keeps saying
>
incorrect syntax near ":"
>
I don't know if this has to do with my DB not being Oracle or I'm doing something wrong.
Can someone help me with this problem please?
thanks in advance

Hi
This all seems complicated to me so I think my simplest way would be to use the java code in the aformentioned thread by Sudipto:
public String getUserLogin() throws WorkflowException,
BPMIdentityException,
BPMUnsupportedAttributeException {
String userId = "";
IWorkflowServiceClient wfSvcClient;
ITaskQueryService queryService;
IWorkflowContext wfContext;
// Get username of User Login
String contextStr = ADFWorklistBeanUtil.getWorklistContextId();
wfSvcClient = WorkflowService.getWorkflowServiceClient();
queryService = wfSvcClient.getTaskQueryService();
wfContext = queryService.getWorkflowContext(contextStr);
userId = wfContext.getUser();
return userId;
} I don't know where and how I should put the code to be called when the view object loads though.
I have created a class in the java class section of my view object which has two methods related to the bind variable input_empCode:
getinput_empcode and setinput_empcode , as expected.
however any code i try to put in those two would not be called at all!
for example:
    public Integer getinput_empCode() {
        //return (Integer)getNamedWhereClauseParam("input_empCode");
        return 1444;
    }and
    public void setinput_empCode(Integer value) {
        //setNamedWhereClauseParam("input_empCode", value);
        setNamedWhereClauseParam("input_empCode", 666);
    }It just keeps filled with the values in the bind variable section.
I don't know what I'm doing wrong here.
would you show me the way?
Thanks again
