Order By in Named Query

Hello,
is it possible to set ORDER BY in a Named Query Expression build through the Expression Builder?
Or is it possible to trigger this while executing the Named Query in the UnitOfWork?
Thanks,
Thomas

Nemata,
The mapping editor in JDeveloper does not yet allow you to configure query ordering. To do this you will need to write a piece of code called an after-load or ammendment method that customizes descriptor configuration when being loaded from the XML representation. In this method you will look up the query you defined and customize any additional settings, such as ordering.
An example after-load method would be placed on any arbitrary helper class and would look like:
    public static void afterLoadEmployee(ClassDescriptor descriptor) {
        ReadAllQuery raq = (ReadAllQuery)descriptor.getDescriptorQueryManager().getQuery("findAllEmployee");
        raq.addAscendingOrdering("lastName");
    }To have this method invoked you will need to configure it on the descriptor in the JDeveloper mapping editor.
1. In the structure pane when the map is selected go to the descriptor for the class you wish to customize its query.
2. Using the right mouse menu on the descriptor select the advanced properties sub-menu and select 'after-load'. This will enable the additional after-load tab on the descriptor's editor.
3. In this after-load panel you will need to specify the helper class where the static after-load method is written as well as the signature for the method wanted.
Now, the next time the application is run this method will be invoked and you ordering customizations will be applied.
This may sound a little complex but is a very useful technique for configuration or customization of descriptor, mapping, or query parameters that are not visible in the mapping editor or are more easily accomplished through code.

Adding "order by" functionality to the expression of a toplink named query

hello,
using JDev 10.1.3, I have made a Toplink named query findCustomersByCompany with a parameter company (String) to pass the name of the company of interest. I used the expression option from the format tab with"1.companyId LIKE IGNORE CASE company".
The selection works fine but now I want the results to be ordered by customer name, the native order in the database is based on creation date.
How can I add the order by clause to my named query using the expression format?
kind regards,
Nemata

Look at http://www.thespot4oracle.com/SQL/re-6593_Adding-an-ordering-clause-using-a-TopLink-amendment-method.aspx
Hope this helps.

Named query, nested

If I defined a named query like the following select * from (
     select q.*, rownum r from user04.quote q
     where version = 1
     order by id
where r between #startIndex and #endIndex I can achieve the 'paging' function by specifying the starting row and ending row for the query at runtime.
However, if I modify the query by supplying an argument in the inner select, like this select * from (
     select q.*, rownum r from user04.quote q
     where version =#id
     order by id
where r between #startIndex and #endIndex my code will fail with NullPointerException in SQLCall. Here is the trace: [5/28/05 19:48:40:816 EDT] 468db180 SystemOut     O 2005.05.28 07:48:40.816--ClientSession(1108210094)--Thread[Servlet.Engine.Transports : 2,5,main]--java.lang.NullPointerExceptionjava.lang.NullPointerException

Solved the problem by
1) adding an space (i.e. blank) after #id
and 2) removing the blank line at the end of the SQL query.
It seems that there is a bug in the TopLink code parsing the SQL. My best advice is to not use new line, tab. Use hard space as de-limiter instead. The debugging is very time-consuming.
Please feel free to comment on my findings.

IllegalArgumentException when using Constructor expression in Named Query.

I have the following JPQL-query:
SELECT NEW se.callista.test.dto.EmployeeReportData(e.firstName, e.lastName, a.city, e.employmentPeriod.startDate) FROM Employee e JOIN e.address a ORDER BY e.lastName, e.firstNamewhere EmployeeReportData is a dto (not an entity). The query works fine when running it as a normal query. When I put it as a named query however, I get the following error message when trying to execute it: java.lang.IllegalArgumentException: Object: se.callista.test.dto.EmployeeReportData@10f9644 is not a known entity type.
I can't find anything in the JPA-spec that says a named query cannot contain a constructor expression - am I missing something?
Found the error. It works fine now :)

I had the same problem.
It seems that the Entity class is not loaded by the JVM at the moment of calling createNamedQuerey(string).
I've solved this problem by loading the entity class manually in the caller by calling "Class.forName(string)" and passing the entity's class name as a parameter.

Native TopLink named query with named parameters

Hello,
Defining my metadata in native TopLink xml and using the native TopLink's Session interface I can access and successfully execute a named query using positional parameters (parameters passed to match the ?1 ?2 etc). I used for this the Session.executeQuery(String, Class, List) method e.g.
select p from Person p where p.name = ?1
Now, how can I get the same Session to execute named queries using named parameters? None of the Session.executeQuery methods seem suitable ... Am I missing anything here? e.g.
select p from Person p where p.age = :age
I can't find in Session http://www.oracle.com/technology/products/ias/toplink/doc/1013/main/b13698/oracle/toplink/sessions/Session.html a good match for this use-case. I would expect something like:
Session.executeQuery(String queryName, Class target, List argNames, List argValues)
or
Session.executeQuery(String queryName, Class target, Map argsKeyedByName)
but can't find any good match, can anyone please enlighten me?
Thanks in advance,
Best regards,
Giovanni

Hello Chris,
Many thanks for your response. I am sorry if I did not explain my problem properly.
Suppose I already defined a named query in the metadata XXXProject.xml using the <opm:querying ... this JPQL named query "customFinder" already exists and would look something like:
select p from Person p where p.firstname=:firstname and p.lastname=:lastname and p.birthdate=:birthdate
now say you want to execute this query from the Session:
Vector args = new Vector();
// how do you know the order? you shouldn't know the order!
// you know only the parameter names and that's what I mean
// about named parameters
// This args setup is wrong ... I need a way to specify to which
// parameter name each argument corresponds to. In other words
// if the named query where criteria order of parameters is modified
// perhaps because of pruning composite keys etc you won't break the
// existing code ...
args.add(new Date());
args.add("Azua");
args.add("Giovanni");
Session session = ...
session.executeQuery("customFinder", Person.class, args);
JPA supports both type of queries positional parameters and named parameters. Your explanation above is only for the first, my question refers to the later.
I have not yet found the api for this ... though I am investigating along the lines of:
Query query = session.getQuery("customFinder");
and then try to assign the arguments in the same order that the parameters are defined in query or?
Thanks in advance,
Best regards,
Giovanni

Sorting named query result

hi, i am using an amendment method to sort named query results, it works fine for the queries that takes no parameters , but when it comes to a parameterized named query it doesn't work, any idea?

hi, thank you for your reply,
1- this is the code of the amendment method:
ReadAllQuery raq =
(ReadAllQuery)descriptor.getDescriptorQueryManager().getQuery("findUsersByCompany");
raq.addDescendingOrdering("name");
2- what do you mean but how do i execute the query?
actually i have wrapped the named query in a session bean method, and i have simply dragged the method from the data control into my web page in a readonly table, i pass the parameter in a static manner in the page definition
3- the result is displayed, no error is showed but it's not ordered correctly
!!!

Question on named query

Is it posssible to define one named query to handle the following three kinds of queries?
select * from vista_order where brand = #brand and factory_order_no between #fromValue and #toValue order by #sortType
select * from vista_order where brand = #brand and order_no between #fromValue and #toValue order by #sortType
select * from vista_order where brand = #brand and nsc_order_no between #fromValue and #toValue order by #sortType
We'd like to supply the column names (i.e. factory_order_no, order_no, or nsc_order_no) at runtime, in addition to the arguments. Does TopLink support that?
Thanks.
Haiwei

Haiwei,
No, TopLink's named queries only support argument substitution and not field/column. You could use a named re-direct query to dynamically create these queries but still have the simple API for query execution.
Cheers,
Doug

TopLink doesn't sort data received using Named query

Hello!
I'm trying to build a Tree table using a TopLink Named query in my application.
There are Id, Parent|_Id, Code and Name columns in the corresponding database table, where Id and Parent|_Id are linked together by Foreign key (typical tree). I used TopLink to describe this table in the Model part of my application. There I wrote a Named query, without using a query constructor (not Expression radio button, but SQL radio button). Here the text of query:
select * from regions a connect by prior a.Id = a.Parent_Id start
with a.Id is null order by a.Code
Then I created a Data control and tried to build a JSF page with data based on this query, as tree-table.
But I discovered the fact, that data under the same node on the same leaf level of the Tree are not sorted by code on the JSF page. For example, data may be situated as follows (Code - Name):
2. wwwwwwwwwwww
2.3.kkkkkkkkkkkk
2.1.fffffffffffffffffffff
2.2.oooooooooo
1. qqqqqqqqqqqqqqqq
1. 2. lllllllllllllllllllllllllllll
1. 1. hhhhhhhhhhhhhh
etc.
I verified this query on other environment (PL/SQL Developer, SQL+), but didn't found such unsorted results anywhere.
Please, give me an advice to avoid this problem.
Thanks.

Hi
Something to do with TreeMap(TreeSet). I tried with TreeSet but it didn't work. Here is the code :
In servlet :
Connection lConnection = getConnection(pRequest);
String lSQL = "";
Statement lStatement;
ResultSet lResultSet;
Hashtable lLtypeHashtable = new Hashtable();
lStatement = lConnection.createStatement();
lSQL = "SELECT RCID,RCMEANING FROM REFERENCECODES WHERE RCDOMAIN = 'LOCATIONTYPE' AND RCROWSTATE > 0 order by RCMEANING";
lResultSet = lStatement.executeQuery(lSQL);
while(lResultSet.next())
String lRcid = lResultSet.getString(1);
String lRcmeaning = lResultSet.getString(2);
lLtypeHashtable.put(lRcid.trim(),lRcmeaning.trim());
if(lResultSet != null) lResultSet.close();
if(lStatement != null) lStatement.close();
pRequest.setAttribute("LtypeHashtable",lLtypeHashtable);
//Below Query is executed when one data from select element is selected
String lLType = DisplayUtilities.getString(pRequest.getParameter("LType"),true);
//LType is name of select element in JSP.
if (lLType != null)
lSQL = lSQL + " AND " + lUpperCaseFunction + "(LOCATIONTYPE)" +
" = " + DBUtilities.formatString(lLType.toUpperCase());
pRequest.setAttribute("rLType",lLType+"");
In JSp :
<%
Hashtable lLtypeHashtable = (Hashtable)request.getAttribute("LtypeHashtable");
%>
<TR>
<TD width="15%"> <div align="left">
<select name="LType" size="1" >
<option Value="">< Select ></option>
<%
if(lLtypeHashtable != null)
Enumeration enum = lLtypeHashtable.keys();
while(enum.hasMoreElements())
String key = (String)enum.nextElement();
String value = (String)lLtypeHashtable.get(key);
String flagBack = "";
if(key.equals((String)request.getAttribute("rLType")))
flagBack = "selected";
%>
<option Value="<%=key%>" <%=flagBack%>><%=value%></option>
<%
%>
</select></div>
</TD>
</TR>
How should I implement TreeSet?
Looking forward for an early reply.
Thanks.

How to write named query if we want to use IN syntax in our sql statement?

I cannot find a suitable category about named query, so please move to appropriate place if there is any.
When we write named query, below statement is fine.
Query q2 = em.createQuery("SELECT o FROM Table1 as o WHERE field1 = :input1");             q2.setParameter("input1", "value1");
Now, my question is, how can I write this type of query when we want to use the IN sql syntax? As below statement CANNOT return correct results. Even I tried to put a pair of single quote [ ':input2' ], it won't help also.
Query q2 = em.createQuery("SELECT o FROM Table1 as o WHERE field2 IN (:input2)");             q2.setParameter("input1", "3633, 3644");
Can anyone suggest? Thanks.

Can anyone suggest?The above is in your code right? Not in some configuration file?
Then you do it the same way as with regular jdbc/sql.
1. You start with a collection of values - call it collection A.
1. Create a for loop that dynamically creates the string using 'bind' variables (whatever you want to call the 'colon' entity in the above).
2. Call the createQuery method using the string that was created
3. Create a second loop that iterates over A and populates with setParameter.
Pseudo code
        Object[] A = ...
        String sql = "SELECT o FROM Table1 as o WHERE field2 IN (";
        for (int i=1; i <= A.length; i++)
              if (i == 1)
                 sql += ":input" + i;
             else
                 sql += ",:input" + i;
        sql += ")";
        Query q2 = em.createQuery(sql);
        for (int i=1; i <= A.length; i++
              q2.setParameter("input" + i, A[i-1]);
              }By the way there is a jdbc forum.

Snowflake dimension: named query vs. database view

A test question features a Product table with a Product Size code; Product Size description is taken from ProductSize table. As far as I can tell, the question asks me to choose between (a) setting up a database view joining Product and ProductSize, and
(b) doing the join in a data-source-view named query. I don't see a clear winner. (My thinking is as follows. Yes, he view would speed up the processing, even if not materialized. On the other hand, with a small dataset, the performance gain would be
minor in absolute terms. Do I want to have an extra database object in the picture?) Yet the question's author does. Can anyone advise please?

Hi Demyan,
According to your description, you want to know which is better, using named query in datasource view or using database view, right?
Based on my research, there is no performance differences between using named query in datasource view and using database view because they both result in SQL query being sent to the source system. Here is a blog which discuss this issue.
Consistency: If you already have logic in database views, I would continue to use them. As long as you know that you go to one spot to view/change the logic. Putting the logic in 2 different spots could lead to confusion.
Security Permissions: often you may not have permission to alter the source databases, in this case you have no choice but to setup named queries in the dsv.

How to create olap cube using Named Query Table in Data source View

I Create on OLAP Cube using Existing Tables Its Working Fine But When i Use Named Query Table with RelationShip To other Named query Table It Not Working .So give me some deep Clarification On Olap Cube for Better Understanding
Thanks

Hi Pawan,
What do you mean "It Not Working"？ As Kamath said, please post the detail error message, so that we can make further analysis.
In the Data Source View of a CUBE, we can define a named query. In a named query, you can specify an SQL expression to select rows and columns returned from one or more tables in one or more data sources. A named query is like any other table in a data source
view (DSV) with rows and relationships, except that the named query is based on an expression.

AVG calculation and syntax error while parsing a named query

Hi all,
I've to calcolate the average of polling results for each value column (5 value column in total). I want to use this single row result line for a bar graph.
I created a new named query in the EJB:
@NamedQueries({
@NamedQuery(name = "Polls.findAll", query = "select o from Polls o"),
@NamedQuery(name = "Polls.findAVG", query = "select o AVG(Value1) as Value1, AVG(Value2) as Value2, AVG(Value3) as Value3, AVG(Value4) as Value4, AVG(Value5) as Value5 o from Polls o")   // <-- my named query
...I tried it in the sql query tool of Oracle 10g XE and sql syntax is ok, but when I run my javaServiceFacade on JDev I receive this message:
Exception in thread "main" Local Exception Stack:

...Where is the syntax error in my named query?
Edited by: Silicio on 22-nov-2008 1.05

Thanks Shay, now I think syntax is correct for gain an average for each column:
@NamedQuery(name = "Polls.findAVG", query = "select AVG(o.value1), AVG(o.value2), AVG(o.value3), AVG(o.value4), AVG(o.value5) from Polls o")But still got some trouble to get a bar graph...
If I drag&drop that query from data control, I get an empty graph with 5 values ,look http://img153.imageshack.us/img153/8710/emptygraphag7.png .
In the log there is some errors (due that named query and its methods in EJB):

IN operator in Named Query

hi all,
is it possible to create a named query containing the IN clause if yes how to pass the parameters , i have smth like that:
"select * from tblUsers where employee_number in #param"
what should be the type of the parameter?

You can create a named query using an IN parameter, but you should be careful in doing this as an IN collection is not a valid parameter in SQL. TopLink will handle translating the IN as long as you are using dynamic SQL, or disable the prepare on the query. You can use Vector as the parameter value.
i.e.
ReadAllQuery query = new ReadAllQuery(Employee.class);
query.setSQLString("select * from tblUsers where employee_number in #param");
// Or: query.setSelectionCriteria(query.getExpressionBuilder().get("number").in(query.getExpressionBuilder().getParameter("param")));
query.setShouldPrepare(false);
query.addArgument("param");
Vector args = new Vector();
Vector param = new Vector();
param.add(new Integer(1));
param.add(new Integer(2));
param.add(new Integer(3));
args.add(param);
session.executeQuery(query, args);
// Or: session.executeQuery("findAllWithNumbers", Employee.class, args);

Derby db named query causes parse error when using derby db MONTH function

Hi all!
I'm trying to create an application using the persistance api and beans binding. I have created my database and entity classes.
My problem is creating a named query that uses some of the functionality from the derby database (which is embedded in the application).
I have a named query:
@NamedQuery(name = "Vehicles.findbymotmonth", query = "SELECT v FROM Vehicles v WHERE MONTH(v.lastmotdate) = :monthnumber") The actual query works fine when I send it directly to the db (with the parameter filled in) but causes an exception when used as a named query:
Local Exception Stack:
Exception [TOPLINK-8025] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.EJBQLException
Exception Description: Syntax error parsing the query [Vehicles.findbymotmonth: SELECT v FROM Vehicles v WHERE MONTH(v.lastmotdate) = :monthnumber], line 1, column 32: unexpected token [MONTH].
Internal Exception: line 1:32: unexpected token: MONTH
at oracle.toplink.essentials.exceptions.EJBQLException.unexpectedToken(EJBQLException.java:389)
... I've tried looking for solutions online but it seems evryone just writes up the original java db application example provided by sun and no one has tried doing more than "select c from customers c".
I'm using the netbeans ide (6.5).
Please tell me there is a simple solution to this and the persistance API can handle complex queries!
Thanks in advance.

one solution: assume the toplink library to be so full of bugs as to be unusable and switch to the hibernate persistance manager where it works fine.
