Problem while using aggregate functions in EJB QL 2.1

Hai all,
I am using aggregate function as follows
select max(c.id) from customer as c
for this iam selected check box EJB QL 2.1 in persistent.xml
this is validated by nwds, but while deploying server raising error like ejb ql syntax error.
Actually according to EJB QL 2.1 this is a valid query, what i need to do for run this same query .
Anybody please help me in this regard
Regards
Somaraju

Beevin
Both two are not even validated,
but with the first one as select max(c.id) from customer as c , in this case it is validated but while deploying it is error as , object must be return
But when i saw the ejb2.1 specification we can write this type of queries also ?
Is it problem with was any thing
Regards

The problem i am getting is when the value is getting compared with the opportunity cost rather than with the sum of oppCost
A as sum(A.opportunityCost)>1000
A as A.opportunityCost >1000
Both the cases are treated as same .

It would help if you could provide sample input data and associated output that illustrates the problem

Should your query be a valid SQL query?
I can't think that the query you have would be valid in a SQL plus window.

Using Aggregate function in queries

Hi all,
          Please take a look on this query and suggest me why i'm getting the error..
This is my simple query using aggregate function in it..
SELECT T1.NAME, T1.DESCRIPTION, SUM(T2.QUANTITY)
FROM TABLE1 T1, TABLE2 T2
WHERE T1.ID=T2.ID
GROUP BY T1.NAME, T1.DESCRIPTION
Above query added with a sub-query in the select segment..

How to use Aggregate Functions during Top N analysis?

Say i want to find top 5 highest salaries and their totals and average. In that case how to use aggregate functions. Please give me an example on this.
Regards,
Renu

Hi,
Yes, you can do that with aggregate functions.
First, do a sub-query to retrieve all the salaries (in descending order), then say "WHERE ROWNUM <= 5" in the main query. Use the aggregate SUM and AVG functions in the main query.
Analytic functions are easier to use for jobs like this, once you get familiar with them. If you're not leaving the field this month, then it's probably worthwhile for you to get familiar with analytic functions.

How to use aggregate function with Date

Problem while using trigger from line of 6534

I have faced some problems while using triggering with 6534. They are listed below. Please provide solution me.
1. ) i was using pattern input with triggering(buffered) in which i am using the example given in library buffered pattern input-triggered.vi
Now i am using port 0 to take input. From line 0 of port 2 i want to generate a pulse which can trigger the operation & start acquisition. For that i am using write to single line.vi . My DPULL is open so bydefault the line will be at low level & by vi i will make it high which will trigger the operation.
In normal condition if we use write to a single line.vi it will write the given status on that line within a fraction of second and abort execution. But when i am usin
g it for trigger in following manner, it did not work.
First i started the VI buffered pattern input-triggered.vi.I have configured the start trigger with leading edge trigger. I have set the time limit properly.Synchronous operation is set at the front panel of vi.
Now if start the write to a single line.vi to give start trigger, nether it triggered the operation,nor it abort execution of single line write vi.When time out occured in triggered vi, then both vis stopped simultaneously. Why this happened?
2.) Similar problem i faced when i wanted to perform the change detection.vi Port 0 is configured for input.Line 1 to 7 are fixed with some status by connecting them to Vcc or GND. I have connected port 0 line 0 with port 2 line 0. So when i change status of line 0 of port 2 change detection should be occured o port 0. i am changing the status of line 0 of port 2 by write to a single line.vi But here i faced same problem as first that it was not writing to port 0 line 0. And bo
th process stopped when time limit occured in change detection vi.
So what can be the problem? Please help me.

Hi Vishal,
1) You should check to see that when you are writting a static 1 to line 0 you see a pulse high. You should also make sure that you wire this line to the STARTTRIG for group 0.
2) If you solve question 1 you will also have question 2 solved.
It might be helpful to create a program that configures both programs (pattern I/O on port 0 and static I/O on port 2) in the same program and then starts both groups. I would do a little testing to see exactly what signals you do or do not see.

Problem while using h:selectOneMenu tag

Hello All,
I am facing a problem while using the <h:selectOneMenu in my JSP.
My requirement is as below,
I am having a list of manager in the select box.
User will select any of the manager and click a command link to assign the manager.
On click of this command link backerbean method should be invoked.
My problem is,
I am able to display the list box without any problem.
But Once I select any value from the list box the command link is not working.
That is click on the command link is not invoking the backer bean method.
My code look as below,
JSP
<td>
<h:selectOneMenu value="#pc_EmployeeDetailsView.assignedMgrPositionId}" id="assignedMgrPositionId" style="width: 170px">
<f:selectItems value="#{pc_EmployeeDetailsView.managerList}" />
</h:selectOneMenu>
</td><td>�</td>
<td><h:commandLink action="#pc_EmployeeDetailsView.assignManager}" onmousedown="setEditAction('assign');">
<h:outputText value="Assign"></h:outputText>
</h:commandLink></td>Backer Bean
     SelectItem managerSelectItem = new SelectItem("0","Select Manager");
     ArrayList managerSelectItemList = new ArrayList();
     managerSelectItemList.add(managerSelectItem);
     int managerListSize = managerSearchList.size();
     for (int i=0; i<managerListSize; i++) {
          Employee manager = (Employee) managerSearchList.get(i);
          managerSelectItem = new SelectItem(StringUtils.isNotEmpty(manager.getOrgInfo().getPositionNumber())?manager.getOrgInfo().getPositionNumber():"",StringUtils.isNotEmpty(manager.getFullDisplayName())?manager.getFullDisplayName():"");
          managerSelectItemList.add(managerSelectItem);
     setManagerList(managerSelectItemList);Please help me on this.
Thanks In Advance

I have solved this problem by putting the list in portlet session and allowing the get method to get the SelectItem from the session
