The Query Question.

Question

Hi everyone.
I created a Query button. And the MB's code is:
ApplicationModule am=ADFUtils.getApplicationModuleForDataControl("HrModuleDataControl");
ViewObject vo=am.findViewObject("HrHumanView1");
int tmp=vo.getCurrentRowIndex();
vo.setNamedWhereClauseParam("HumanSort","abc");
vo.executeQuery();
vo.setCurrentRowAtRangeIndex(tmp);
There is 100 records in my database,and the view of HumanSort='abc' have 30 records. If I execture other query operate, for instance,there is 70 records left, next I execture this query operate, the result doen't query from the 70 records,it still query from 100 records.
And on other page, I have a button used the same MB's method. It query from the 70 records.
I don't understand it.
I have already set the task flow 's Data Control Scope to shared.
Help me.Thanks.

I didn't quite understand the problem that you are having, sorry.
First, you can accomplish what your code above is trying to do using declarative features of ADF. The ExecuteWithParams built-in operation assigns values for named bind variables of a view object then re-executes the query.
You need to provide a bit more details about what you mean by "I execute other query operation" (how was this first step achieved? declaratively? using code?) followed by "next I execute this query operation" (assuming you mean the code that sets the bind variable value).
It sounds as if you're expecting the second query to further-filter the results of the first query, but I need to understand better what you did in the first step to let you know if what you're seeing is expected behavior or not.
