Named Queries and Finders

Hi, I would like to know if is there a way (in JDev 10.1.3 or in standalone TopLink Workbench) to generate, during mapping, automatic Named Queries that are finders for the table. In example if I have a table with id, name, surname I would like to have in automatic the Named Queries getById(Long id), getByName(String name), getBySurname(String surname). On I project we used Firestorm DAO, which generate automatically these methods, that are quite useful.
Thanks in advance,
Stefano E.

If you are using TopLink 10.1.3 CMP2 in OC4J 10.1.3 then the CMP runtime will automatically define finders for any finder of the format, "findBy<field>" where <field> is the name of a bean cmf. You do not need to define these finders in the Mapping Workbench nor deployment XML.
You can use the Mapping Workbench do define these finders as well, but there is nothing in the Mapping Workbench that allows automatic generation of these finders.

Named Queries and QueryByExample

Folks,
Is it possible to register a named query w/ a descriptors QueryManager AND perform QueryByExample queries?
If so, can you post an example of UnitOfWork call?

No, named queries are static, they have a fixed selection criteria and number of parameters. Query by example is dynamic.

Named Queries and Null parameters

I am trying to use null values in the where clause of named query. I have a named query defined in my Workbench (Toplink 9.0.4) and the where claus looks like this.
WHERE PERSON.LAST_NAME=#lastName
If a pass in a value for lastName, say "Jones", Toplink correctly creates a where clause in single quotes:
WHERE PERSON.LAST_NAME='Jones'
However, if I pass in a null value for lastName, Toplink generates this:
WHERE PERSON.LAST_NAME=NULL
This will never select anything, because a value can never "equal" null, but rather it IS NULL or it isn't.
Any ideas out there on how I could get Toplink to substitute "IS NULL" of "=NULL" in such situations?

Different databases handle = null differently. I assume you are on DB2?
You can force a query to dynamically generate its SQL, to ensure that IS NULL is used.
query.setShouldPrepare(false);
In the Mapping Workbench for the query click on 'Advanced Properties' and un-click 'Prepare SQL Once'.
The database may also process the = null correctly if binding is used, but I'm not sure on this.

Named Queries and Enum error

@NamedQuery(name = "Task.findNumberTasksComplete", query = "select count(o.id) from Task o where o.status like 'C%'")that is the query i am performing. Status is an enumerator type.
When i try to perform this,
int numerator = Integer.parseInt(em.createNamedQuery("Task.findNumberTasksComplete").getSingleResult().toString());I get the following error

SetAdditionalJoinExpression and Named Queries...

Hi, is it possible to use DescriptorQueryManager.setAdditionalJoinExpression() to append additional filters to sql statement named queries?
I've tried this but it doesn't seem to have any effect. If this is not possible, do you know of any alternative methods?
Thanks for you help!
-Tim Watson

Yes, if you set the DescriptorQueryManager additionalJoinExpression the expression will be anded will all queries for that descriptor.
Ensure that you set the additionalJoinExpression before you login.

How to pass parameter to the Query String of the Named Queries'SQL

Firstly to say sorry,I'm a beginner and my English is very little.
Now I want to know
How to pass parameter to the Query String of the Named Queries'SQL in the Map editor.
Thanks.

benzi,
Not sure if this is on target for your question, but see #5 in the link below for some web screencasts that show how to pass an input text form field value to the bind variable of a view object. If you're looking for something different, maybe provide some more details such as what you are trying to accomplish and what technology stack you are using - for example, ADF BC, JSF, etc.

Also see section 5.9 and chapter 18 in the developer's guide.
thanks

OAS 10G WAR file deployment error (Errors in named queries)

Hi again,
I setup a 10G 10.1.3.1 Application Server and tried deploying my WAR file. In tomcat the WAR file deployment works fine. however in OAS I get this error and currently I'm clueless as to what causes the error.
[Oct 24, 2007 6:03:37 PM] Operation failed with error: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: org.hibernate.HibernateException: Errors in named queries: Book_List_By_RegisterDate ...

Named Queries

Hi All,
I am using TL 4.6 Build 418, Oracle 8.1 & WLS 7.0.
I am having a hard time getting Named Queries working. Specifically I can't seem to get Toplink to Bind my parameter(s). I have tried to use both EJBQL and plain SQL with no luck using either. The error I get when I use SQL is that from Oracle or JDBC that not all parameters are bound, when I change the stmt to be EJBQL then I get a null where the bound parameter should go. The stmt is super simple.
EJBQL = SELECT OBJECT(sysuser) FROM SystemUser sysuser WHERE sysuser.username = ?1
or as
SQL = SELECT * FROM SystemUser WHERE username = ?1
For a test I took the mapping work bench code that is generated into java source and pasted it into a test servlet below.
ReadObjectQuery namedQuery0 = new ReadObjectQuery(com.aravo.security.biz.usermgmt.SystemUser.class);
namedQuery0.setEJBQLString("SELECT OBJECT(sysuser) FROM SystemUser sysuser WHERE sysuser.username = ?1");
namedQuery0.setName("getSystemUserwithUserName");
namedQuery0.setCascadePolicy(1);
namedQuery0.setQueryTimeout(0);
namedQuery0.setShouldUseWrapperPolicy(false);
namedQuery0.setShouldBindAllParameters(true);
namedQuery0.setShouldCacheStatement(false);
namedQuery0.setSessionName("security");
namedQuery0.setShouldMaintainCache(true);
namedQuery0.setShouldRefreshIdentityMapResult(false);
namedQuery0.setLockMode((short)0);
namedQuery0.addArgument("uname", java.lang.String.class);
clientSession.addQuery("getSystemUserwithUserName", namedQuery0);
Vector theArgs = new Vector() ;
theArgs.addElement("[email protected]") ;
SystemUser su = (SystemUser) clientSession.executeQuery("getSystemUserwithUserName",theArgs) ;
What I then see is the following in the console. Any ideas why NULL is there instead of [email protected]?
SELECT PASSWORD, USERNAME, SYSTEMUSERID FROM SYSTEMUSER WHERE (USERNAME = ?)
bind => [null]
Thanks,
Jerry

It looks like you have a small error in your setup.
Is see your EJBQL =
namedQuery0.setEJBQLString("SELECT OBJECT(sysuser) FROM SystemUser sysuser WHERE sysuser.username = ?1");
But then you pass the argument =
namedQuery0.addArgument("uname", java.lang.String.class);
It should be =
namedQuery0.addArgument("1", java.lang.String.class);
In other words, the name of the argument from the argument list should be the same as the one in the EJBQL.

Lost Named Queries of TopLink + Information

Hi everyone!
We are developing an application web with TopLink technology and I want to known in which situations or operations we can lost the named queries that we made in base of yours experiencies, because we are newer in this technology.
We will be waiting your response!
Greetings!

If you add or remove columns from a table then you should add/or remove attributes from your mapped class and fix anything in the mappings resulting from the change. The mapping editor functionality is intended for a meet in the middle usage. The generation is intended to be done to bootstrap a project or completely re-create a model following major changes to the database schema.

I want to export named queries (only)

IOP has some commands to import / export individual objects.
i see even import named queries command is there to import details from named_queries.xml however there is no command documented / available to export named queries.
same is true for acls, and some response data objects.
one needs to do prepare migration / export model definitions to get acl / named queries / associated queries
it is useful when we are working on big model and need to make small changes..

The "Named Queries" are associated with worksheet, scenario, security filter and these are non shadow objects. So it make sense to export the definitions of named queries while exporting the model definitions.

Two similar queries and different result.

We have "sc as (select * from nc_objects where object_type_id = 9122942307013185081 and project_id=9062345122013900768)"
and identical subquery on caloc and cbloc
"select value from nc_params sccid where sccid.object_id = sc.object_id and sccid.attr_id = 9122948792013185590"
If i change query on
with
sc as (select * from nc_objects where object_type_id = 9122942307013185081 and project_id=9062345122013900768),

query result will be:

Hi,
Welcome to the forum!
Whenever you post code, format it to show the extent of sub-queries, and the clauses in each one.
Type these 6 characters:
\(all small letters, inside curly brackets) before and after each section of formatted test; if you don't, this site will compress the spaces.
It also helps it you reduce your query as much as possible. For example, I think you're only asking about the sub-query called caloc, so just post caloc as if that were the entire query:select     ( select CIRCUIT_ID
     from cid
     )                as CIRCUIT_ID,
     ( select sl.name
     from nc_objects          sl
     join nc_references      scr on sl.object_id = scr.reference
     where scr.attr_id      = 3090562190013347600
     and scr.object_id      = sc.object_id
     )                as ALOCATION
from sc
This makes it much cleared that the query will produce 2 columns, called circuit_id and alocation.
Compare the query above with the query below:SELECT     object_id,
     'Okay'
FROM     sc
The basic structure is the same: both queries produce two columns, and both queries produce one row of output for every row that is in the sc table.
The only difference is the two items in the SELECT clause.
The second query has a column from the table as its first column, and a literal for its second column; those are just two of the kinds of things you can have in a SELECT clause. another thing you can have there is a +Scalar Sub-Query+ , a complete query enclosed in parentheses that produces exactly one column and at most one row.   If a scalar sub-query produces more than one row, then you get the run-time error: "ORA-01427: single-row subquery returns more than one row", as you did.
A scalar sub-query always takes the place of a single value: "scalar" means "having only one value". In the first example above, the main query is supposed to produce one row of output for every row in sc. How can it do that if some of the columns themselves contain multiple rows?
I don't know what your tables are like, or what output yu want to get from thiose tables.
If you'd like help getting certain results from your tables, then post CREATE TABLE and INSERT statements for a little sample data, and the resutls you want to get from that sample data. A scalar sub-query may help getting those results, or it may not.

I am working on a friend of mine's 15g ipod(W/dock connector)and I am having the same trouble except it does it to all the songs. I have tried reseting it multiple times, but to no avail.
I am not sure that this runs on windows XP, it is absolutly archaic (compared to my 5th gen. 30g video).
Help?

I upgraded my new iPad (iPad 3) to IOS 6 and everything went well except Siri won’t launch apps. When asked say “launch Facebook” Siri responds with “it doesn’t look like you have an app named Facebook” and I get the same results when trying to launch any app. Siri works for everything else it just won’t launch apps. Any ideas? Thanks.

I have this same problem... Seems like nobody else does. Siri won't launch any apps for me, including native apps.
