Limiting records in a named query

Hello,
I can retrieve all the records using the following named query:
<named-query name="emploee.findemployees">
<query>select e from employee e </query>
</named-query>
Can somebody help me how i can retrieve only the first 5 records using the named queries?
Thank you in advance,
Reddy

Thanks for the tip vijaykumar. Your tip helped me to go further.
TOP keyword only seem to work with SQLServer 7.0 and above.
We are using MySQL. So the equivalent syntax in MySQL is
Select * from employee LIMIT 0,5.
This query works fine in my MySQL Query Browser. But it does not work with Hibernate. Does anybody know how to make this query work with Hibernate?
Thanks in advance,
Reddy

Can't execute SQL Named query that uses connect by...

I'm having problems using the connect by with ReportQuery.setHierarchicalQueryClause (detailed in earlier post) so I defined a named query to execute the following sql;
select distinct(role_id)
from role_principal
connect by prior role_id = principal_id
start with principal_id = #principalId
When I run similar SQL in SqlPlus, i get results like this;
ROLE_ID
202
500
501
502
503
But when I run the query using Toplink like this;
Vector args = new Vector();
args.add(principal.getId());
roles = (Vector) session.executeQuery("orclGetRolesOfPrincipal", args);
I get this exception;

It seems to have a problem that there's not a parent record for role_id 202, which is a root level record and so should not have a parent.
I appreciate any help that can be provided.
Thanks,

Hello Tim,
Not sure of the problem in the first post, but in this one, you are executing the query as a ReadAllQuery. The results only contain the role_id, but TopLink expecting atleast all the primary key fields inorder to build the objects to return them to you. Try executing this SQL in a report query instead, or set the results to return all the fields so TopLink can build the objects.

Named query cache not hit

Hi,
I'm using Toplink ORM 10.1.3.
I have a table called STORE_CONFIG which has a primary key called KEYWORD (a VARCHAR2). The POJO mapped to this table is called StoreConfig.
In the JDeveloper (10.1.3.1.0) mapping workbench I've defined a named query to query by the PK called "getConfigPropertyByKeyword". The type of the named query is ReadObjectQuery.
SELECT keyword, key_value
FROM STORE_CONFIG
WHERE (keyword = #key)
Under the options tab I have the following settings:
Cache Statement: true
Bind Parameters: true
Cache Usage: Check Cache by Primary Key
The application logs show that the same database queries are executed multiple times for the same PK (keyword)! Why is that? Shouldn't it be checking the Object Cache rather than going to the DB?
I've tried it with "Cache Statement: false" and "Bind Parameters: false" with the same problem.
If I click the Advanced tab and check "Cache Query Results" then the database is not hit twice for the same record. However it was my understanding that since I am querying by PK that I wouldn't need to set "Cache Query Results".
Doesn't "Cache Query Results" apply to the Query Cache and not the Object Cache?

Your issue seems to be that you are using custom SQL for the query, not a TopLink expression. When you use an Expression query TopLink's know if the query is by primary key and can get a cache hit.
When you use custom SQL, TopLink does not know that the SQL is by primary key, so does not get a cache hit.
You could either use an Expression for the query,
or when using custom SQL you should be able to name your query argument the same as your database field defined as the primary key in your descriptor (case sensitive).
i.e.
SELECT keyword, key_value
FROM STORE_CONFIG
WHERE (keyword = #KEYWORD)

Named query question

Hi Guys,
I have the following problem - I know I did something wrong, but I cannot figure out how to correct it. Here is my question:
I have a table tableA, with composite key (col1, col2, col3, col4). I mapped the table, and create a Toplink named query (findCol3List)as such:
select distinct col3
from tableA
where col1=#col1 and col2=#col2
I created an EJB session method getCol3List(col1, col2) -
now when I run the application to call this EJB method, I got the following error at line:
List results = (List)session.executeQuery("findCol3List", String.class, params);
Exception Description: Missing descriptor for [java.lang.String] for query named [findCol3List].
I know there are multiple mistakes in my approach, but with my limited Toklink knowledge, I could not figure out.
Any help with be appreciated!

hello,
The executeQuery method is trying to look up the "findCol3List" in the descriptor for the class passed in. It is complaining because you passed in String.class which does not have a valid descriptor.
How/where did you define the named query? Chances are you defined it in the class used for TableA, and so should specify it in the executeQuery method:
session.executeQuery("findCol3List", tableA.class, params);
Best Regards,
Chris

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.

Haiwei

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.

Named query in Entity Bean - Problem with embedded class

Hello Forum,
I'm trying to set up a named query in my Entity Bean and I'm unable to get
it up and running for an embedded class object.

Someone in the SAp forum mentioned:
The problem here is that you compare an input-parameter with an embeddable field of your entity.
Regarding to the JPQL-grammer (spec 4.14) you are not allowed to compare
with the non-terminal embeddable field but with the terminal fields of your
embeddable. Stating that your embedded class might have the fields
startTime and endTime your JPQL query might look like this:
Query q = em.createQuery("SELECT count(obj.databaseId) FROM SapUserData obj WHERE obj.timeSlice.startTime = :startTime AND obj.timeSlice.endTime = :endTime");
q.setParameter("startTime", foo.getStartTime());
q.setParameter("endTime", foo.getEndTime());
q.getResultList();
This limitation in the JPQL grammar is rather uncomfortable.
An automatic mapping of the parameter's fields to the terminal fields of your
embedded field would be more convenient. The same can be said for lists
as parameter-values which is possible in HQL, too. I think we have to wait
patiently for JPA 2.0 and hope for improvements there. :-)
With that help I was able to get it up and running for the timeSlice field but
I don't see the difference to the dayOfAggregation field which is also just
another embedded class using an object of a class annotated with
@Embeddable.
The get method of the dayOfAggregation field is as follows:
     * Get method for the member "<code>dayOfAggregation</code>".
     * @return Returns the dayOfAggregation.
    @Embedded
    @AttributeOverrides({@AttributeOverride(name = "calendar", /* Not possible to use interface constant here - field name must be used for reference */
                                            column = @Column(name = DayContext.COLUMN_NAME_DAY_OF_AGGREGATION,
                                                             nullable = false)),
                         @AttributeOverride(name = "weekday",
                                            column = @Column(name = DayContext.COLUMN_NAME_WEEKDAY,
                                                             nullable = false)),
    public Day getDayOfAggregation() {
        return this.dayOfAggregation;
    }The link to my question in the SAP forum for reference:

Toplink named query and firstrow

In one of our projects we have a need to chunk records returned by a Toplink query.
For example if a query retrieves 1000 rows we need to chunk records in batches of a variable number.
Lets assume for this one request we need to chunk these 1000 rows in batches of 50 records. Is there a way to do this with Toplink?
I tried to create a named query and then am setting the first row to 0 and max rows to 20
And in a loop I am adding 20 to the value of the first row.
This does not work. The first time the query runs the first row = 0 and the max rows = 20 and I get 20 records back as I expected, but the next time the query runs after I change the value of firstrows to 21 and I do not get any records back even though the DB has a 1000 records.
Is it possible to do this sort of batching of the result set? I appreciate any pointers on how to solve this
Thanks a lot for the help

Hello,
MaxRows is independent of firstResult in TopLink; unless using a database that supports pagination, MaxRows is applied to the statement, and then firstresults used on the returned resultset to skip to the desired first row. So, the driver would return 20 rows, and then firstResult skips to row 20 - so nothing gets returned.
MaxRows and FirstResult are used in TopLink as the range you want to be returned. So both need to be incremented so that the difference between them is the max number of rows you want returned - MaxRows could be better described as a LastResult instead.

Chris

Fetching limited records SQL

Hi All,
Need all your valuable advise again.
The ISSUE is :-
Rightnow, the SELECT below , the inner query will fetch all the records from the database. Outer query will fetch the exact block of records from the inner query results(total available).
Example:- Lets consider a person search query is used to filter the records by department. Assume this query yields 30K records
Whatwe do today is,
SELECT * FROM(
SELECT
rownumrownumber,deptname
FROM person
WHERE department = 'Electronics' // Assume this inner query fetches 30K records
) WHERE rownumberbetween 100 and 125;// out of 30K we just need the 25 results
Solution:
How do we make the Inner query to limit the maximum records we wanted? Presently,its fetching all records.
SELECT * FROM(
SELECT
rownum rownumber,deptname
FROM person
WHERE department = 'Electronics' ANDrownum<=125 // now the inner query will fetch only 125 records
) WHERE rownumber between 100 and 125;// out of 30K we just need the 25 results

Take a look at these two articles:
[On Top-N and Pagination Queries|http://www.oracle.com/technology/oramag/oracle/07-jan/o17asktom.html]
[On Rownum and Limiting Results|http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html]
These show how to handle all sorts of situation (e.g. if you care about ordering or not). In any case the simple solution is:
Pagination with ROWNUM
My all-time-favorite use of ROWNUM is pagination. In this case, I use ROWNUM to get rows N through M of a result set. The general form is as follows:
select *
from ( select /*+ FIRST_ROWS(n) */
a.*, ROWNUM rnum
      from ( your_query_goes_here,
      with order by ) a
      where ROWNUM <=
      :MAX_ROW_TO_FETCH )
where rnum >= :MIN_ROW_TO_FETCH;
where
    * FIRST_ROWS(N) tells the optimizer, "Hey, I'm interested in getting the first rows, and I'll get N of them as fast as possible."
    * :MAX_ROW_TO_FETCH is set to the last row of the result set to fetch—if you wanted rows 50 to 60 of the result set, you would set this to 60.
    * :MIN_ROW_TO_FETCH is set to the first row of the result set to fetch, so to get rows 50 to 60, you would set this to 50.
The concept behind this scenario is that an end user with a Web browser has done a search and is waiting for the results. It is imperative to return the first result page (and second page, and so on) as fast as possible. If you look at that query closely, you'll notice that it incorporates a top-N query (get the first :MAX_ROW_TO_FETCH rows from your query) and hence benefits from the top-N query optimization I just described. Further, it returns over the network to the client only the specific rows of interest—it removes any leading rows from the result set that are not of interest. Just plug your query (without trying to worry about the number or rows returned) into the template query. The articles explain how to do more complex things.

Named Query does not refresh

I have a named query that has one parameter against the HR database table Countries and the parameter is the CountryID. I then have a page that shows a edit form based on the named query. I use a bean to pass the value to the parameter and the bean is updated from an action listner. The first time I call the page the selected record is correct, then from then on successive calls to that page with changes to the bean value still shows the same record.

try doing an execute-query action on entry of the page.

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:
Exception [EclipseLink-8023] (Eclipse Persistence Services - 1.0.1 (Build 20080905)): org.eclipse.persistence.exceptions.JPQLException
Exception Description: Syntax error parsing the query [Polls.findAVG: select AVG(Value1) as Value1, AVG(Value2) as Value2, AVG(Value3) as Value3, AVG(Value4) as Value4, AVG(Value5) as Value5 o from Polls o].
Internal Exception: org.eclipse.persistence.internal.libraries.antlr.runtime.EarlyExitException
...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):

Missing Functionality - Records retrieved by this Query)

Hi
The 'Records retrieved by this Query' function which was available in previous versions is now not available in 2007.
Upon executing the query, the number of records do appear on the left but it can be awkward as the column doesn't size correctly for larger numbers for numbers over 100.
Please can this be reintroduced.
Many thanks,
Caroline

Hi Caroline,
The response from SAP support team could be weeks or months if any. You need more patient. However, as in my experience, anything taken out from the previous version would have reasons. Even unknown to most users, to get them back is highly unlikely.
Thanks,
Gordon
