TopLink and Stored Procedures

Hi all
We are migrating an application made with MS ASP's to a full blown J2EE application using ADF, JSF and toplink, atm we've used the mapping abilities from toplink and have saved lots of work, however i'd like to know if there's aw ay to map the Stored procedures the same way you map the tables. This would be a great time saving routine, if not available we might have to write it but I thought we would ask here first. Any pointers?
greetings!

TopLink does fully support invoking stored procedures for any query. It is not available in the graphical mapping editors but is available through the API. Look in the documentation for StoredProcedureCall.

Baffled by Toplink and stored procedures

Here's what I'm after...
I have a nice package built to act as a bridge to a MySQL database. Everything works fine, but I need to write classes to "wrap" two stored procedures (procedures, not functions or triggers, defined in the database itself). I want to leverage the TopLink connection handling so that I don't have to open/close connections for these two classes. Surely there is some way to do this.
Working with one example...
Stored Procedure definition:
CREATE PROCEDURE openPorts (ipAddr INT UNSIGNED)
BEGIN
DECLARE lastScanID INT UNSIGNED;
SELECT results.scanrequestid INTO lastScanID
    FROM (results,network,scanner)
    WHERE
      results.ip=ipAddr and
      results.ip between network.ip and network.ip+pow(2,(32-network.cidr))-1 and
      results.scannerip=scanner.ip and
      scanner.regionid=network.regionid
    ORDER BY results.endtime DESC LIMIT 1;
SELECT distinct protocol,port
    FROM results
    where
      ip=ipAddr and
      scanrequestid=lastScanID and
      port>0 and protocol>0
    ORDER BY PROTOCOL,PORT;
ENDI want to create a class file OpenPortsDAO such that calling
List<OpenPort> ports = OpenPortsDAO.find(int ipInteger)Yields a list (or vector, whatever) of the rows returned as the result.
Ignoring for the moment the issues with mapping returned row fields to object fields in my OpenPort class, how the heck do I...
1) Define the stored procedure
2) Set the input variable value
3) Get the connection (if necessary)
4) Execute the query
I imagine it's going to be something like...
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("hostSummary");
call.addNamedArgumentValue("ipAddr", value);
call.getResult();Should this wrapping class be defined in the persistence unit just like any other? If so, my assumption is then that I would not have to manually handle connections, etc.
Any help would be very much appreciated. I think if I can just get pointed in the right direction, it should "click" for me.

Doug,
Thanks for the info. I was able to handle the stored procedure, but I did so via POJOs.
I'm interested in this part of your reply...
>
This will give you an entity class with a full lifecycle to it assuming that TopLink may write it back to the database if modified in a transaction.
Given the following pseudo-<code|SQL>...
drop table starship
go
drop table contractor
go
create table contractor (
id serial primary key,
name text unique)
go
create table starship (
id serial primary key,
name text unique,
contractor_id int references contractor)
go
create function get_by_id(shipid int, OUT contractor, OUT shipname)
BEGIN
blah
END;
GOAre you saying that I can create a full CRUD object for the function/procedure call? IE., assuming I get back a result and I see that the ship name is incorrect, I could make a change to the returned data and have that persisted? Without having to get a starship object on my own?
If that's the case, I'd like to know more.

DAC task with Informatica mapping and stored procedure (very slow)

Hello,
We have a DAC task that launch an Informatica Workflow with a simple query and stored procedure, like this:
SQL QUERY
==========================
SELECT
W_ACTIVITY_F.ROW_WID,
W_AGREE_D.AGREE_NUM,
W_PRODUCT_D.ATTRIB_51,
W_SRVREQ_D.ATTRIB_05,
W_ORG_DH.TOP_LVL_NAME,
W_ORG_D.ATTRIB_06,
W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_PRODUCT_D.PROD_NAME
FROM
W_AGREE_D,
W_SRVREQ_F,
W_ACTIVITY_F,
W_PRODUCT_D LEFT OUTER JOIN W_PRODUCT_GROUPS_D ON W_PRODUCT_D.PR_PROD_LN = W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_ORG_D,
W_SRVREQ_D,
W_ORG_DH
WHERE
W_SRVREQ_F.AGREEMENT_WID = W_AGREE_D.ROW_WID AND
W_SRVREQ_F.SR_WID = W_ACTIVITY_F.SR_WID AND
W_SRVREQ_F.PROD_WID = W_PRODUCT_D.ROW_WID AND
W_SRVREQ_F.ACCNT_WID = W_ORG_D.ROW_WID AND
W_SRVREQ_F.SR_WID = W_SRVREQ_D.ROW_WID AND
W_ORG_D.ROW_WID = W_ORG_DH.ROW_WID
STORED PROCEDURE
===========================
ConvSubProy(W_AGREE_D.AGREE_NUM,
W_PRODUCT_D.ATTRIB_51,
W_SRVREQ_D.ATTRIB_05,
W_ORG_DH.TOP_LVL_NAME,
W_ORG_D.ATTRIB_06,
W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_PRODUCT_D.PROD_NAME)
The mapping is very simple:
Source Qualifier -> Stored procedure -> Update strategy (only two ports: ROW_WID and custom column) -> Target Table
When I launch the DAC Execution Plan the corresponding task take much time (40 minuts). But when I launch the corresponding Workflow from Informatica PowerCenter Workflow Manager this only take 50 seconds... when I see the log session for the task I can see that much time is spent on the time of the updates. For example, when DAC is running the writer updates 10000 records every 6/7 minuts, but when Workflow Manager is running thw writer updates 10000 records every 8/9 seconds.
So, what happens (in the DAC) to that so much time difference? Is there a way to reduce the execution time when the task is launched from DAC?
Thanks
Best Regards
Benjamin Tey

Have you tried using bulk load type?
In Workflow Manager can you open the associated task, navigate to the mapping tab and seled the target table.
What is the value for "Target load type" and which of the following boxes are checked: Insert, Update as Update, Update as Insert, Update else Insert, Delete?

Database updation using XML and stored Procedure?

Hello,
I want to perform updation in multiple tables using XML files.Please suggest can I do updation using xml and stored procedure.
If yes then which is more efficient and takes less time.
1.Updation using xml files only
2.Updation using xml files with stored procedure.
3.Stored procedure alone.
If direct xml and stored procedure communication is possible.then please write how.
Thanks in advance for any help.

Approval Procedures and Stored Procedures

Hi All
I have a problem with approval procedures and stored procedures.
I created an approval procedure to check if a value in the udf is selected or not . if not then a messge is produced to ask the user to select the person to approve the PO.
Biut now the problem is the PO's are linked approval templates to the error messge don't show before the approval template screen.
Please assist.
Thanks
Bongani Dlamini

Hi Gordon
The stored procedure is just for validating if the user has selected the udf value.
It is not for approval*
I created an approval template for this purpose. So my problem is when I add the Po to the system the SP doesn't kick-in and alert the user to select the person to approve the PO.
Process Flow.
User captures PO then select the value on the UDF Field ( Approver) The value selected is linked to a query which is used by the Approval Template
If this method is still not supported then please let me know .
Thanks
Bongani Dlamini

EJB 3.0 Persistence API and Stored Procedures

Does the EJB 3.0 Persistence API in any way prescribe or facilitate the use of Stored Procedure calls? Given the recent popularity of using (database) server APIs consisting of Stored Procedures that are addressed by ORM frameworks for performing the DML operations and of course the general usefulness of stored procedures for specific data related operations, there definitely is a need for clarity on using the straightforward Persistence operations in combination with calls to Stored Procedures. Can we use the Native Query for executing CallableStatements? Can we get to a Connection instance from the EntityManager? Can we easily use the results from a Stored Procedure invocation to refresh our Domain Objects - or is that all application logic in which the EntityManager cannot help us?
If the spec does not help us at this point, do you know how TopLink will deal with this topic?
Thanks for any help you can give me!
Best regards,
Lucas Jellema

I'm am also interested in a response to this post. I've just upgraded to JDeveloper 10.1.3.1 and am interested in making calls to stored procedures.
I've found examples of just creating my own session beans but it seems I would have to hard code the datasource name. Does anyone know if I can get around this using the entity manager supplied by the tool?
thanks,
Dan

Toplink using stored procedures

I have a stored procedure doing an update on two tables on a database. I would like to use this stored procedure with TopLink. The two tables are mapped to two java objects generated by TopLink in the server cache.
When executed, the procedure first modifies a row on a first table that is mapped to the first Java object. Next, this same procedure also modifies data the other table (which is mapped to a the second java object already in the server cache).
Does anyone know if Toplink would be able to reflect the changes done to the second table to the second Java object in the cache?
Thanks

How do you want to use the stored procedure from TopLink? Would it be used for the object's insert, update or delete operation, or does the procedure not map directly to a CRUD operation?
If the procedure were an update operation and took the fields from the objects as parameters, then you could define a multiple-table descriptor that mapped to both tables and used the procedure for its update operation. You could still have two separate objects if you made one an aggregate.
If the procedure is just performing some application logic, then it would probably be best to just call the procedure directly, and then refresh the two objects. You might also consider performing the application logic in Java instead of in the database.

Toplink with stored procedures

Hi
I am new to Toplink and would like to get an idea whether Toplink would be suitable for our application. Currently, in our application we always access the database through stored procedures. I realize Toplink supports stored procuedres with StoredProcedureCall class. However; I am just trying to get some feedback as to whether using only this feature(as well as handling database connections etc.) of Toplink is a good idea or not.
Thanks,

I have my entity manager setup in a singleton.
I'm finding it's costly to generate the emf, but if I don't close the em (enitity manager) and emf (entity manager factory) my open cursor count climbs until I exceed the max number of open cursors on the database (11g RAC)
I'm committing the connection, and uow, and closing the em at the end of each call.
But until I close the emf, the open cursors aren't released.
TransactionhistoryPkg tranPkg = new TransactionhistoryPkg(conn); //Class created over database package via JPublisher
tranPkg.transactionhistoryInsSp(insertTrans.getCardId()); // executes db package
tranPkg.closeConnection();
conn.commit();
uow.commit();
uow.getAccessor().decrementCallCount();
em.close();
Am I missing something really obvious here??
btw - I found this link helpful in troubleshooting the max cursors issue: https://support.bea.com/application_content/product_portlets/support_patterns/wls/InvestigatingORA-1000MaximumOpenCursorsExceededPattern.html

SQL Server 2008 R2 - Report Builder 3.0 - timeout using shared data source and stored procedure

I select the shared datasource from the data source propeties dialog, test the connection and everything is good.
I add a dataset by selecting "use a dataset embedded in my report" option within the Dataset properties dialog.
I select the newly added data source, click the "Stored procedure" query type and drop down the list box and select my intended stored procedure.
the timeout for the dataset is "0" seconds.
I click the "OK" button and I'm presented with the parameters to the stored procedure.
I enter valid data for the parameters and click the "OK" button.
I then get the following error message after 30 seconds:
The problem is, all of the timeouts, that I'm aware of, have values of zero (no timeout) or high enough values that 30 seconds isn't even close to the timeout.
I think the smallest timeout we have is 120 seconds.
I have searched this site and many others and the solutions all involve altering the stored procedure to get the fields into report builder and then revert the stored procedure back to its original form.
To me, this is NOT a solution.
I have too many stored procedures that need to be brought into Report Builder.
I need a real solution.
Thank you for you time, Tim Caldwell.

I don't mean to be rude, but really, check to see if the stored procedure can return data rows???
Maybe I'm not being clear enough.
The stored procedure runs perfectly fine.
it runs perfectly fine in the production environment and the test environment.
I can access the stored procedure in several ways and have it return correct data.
I can even trick report builder into creating a dataset with parameters and run the stored procedure that way.
What I cannot do, is to get report builder to not timeout after 30 seconds on the initial creation of a dataset with a Query type of stored procedure.
I have seen this issues posted again and again and again on may different sites and the "solution" is to simplifiy the stored procedure by creating a stored procedure that has a create table and a select in the stored procedure and that's it. After
report builder creates the dataset the developer then has to replace the simplified stored procedure with the actual stored procedure and everything works fine after that.
HOWEVER, having to go through this process for 70 or more stored procedures is ridiculous.
It would appear that there is something within report builder itself that is causing this issue.
The SQL Script included is an example of a stored procedure that will not create fields create a dataset with fields and parameters in Report Builder 3.0:

Crystal Report and stored procedure calls

Hi,
1. I am trying to access a Stored Procedure through Crystal Reports 2008. I have 3 Parameters in it and now I need the 2 Parameters from the stored Procedure to be given by User and the 3rd Parameter should be passed from the backend code. Please help me with the setps that would help me do this.
2.I also have another Stored procedure where I have 3 parameters and in addition to that I should provide two other parameters for user to enter. Now the total number of parameters will be 5 Parameters. Can any one let me know how to implement all these parameters.
3. In another Storedprocedure I have two Parameters which are discrete and multi select and both of them are cascaded. How do I implement those.
Thanks
Pradeep

Crystal Reports 9 and Stored Procedures using supplied parameters from user

Hi,
I have a Crystal Reports 9 report that prints and works fine. It requests from the user 2 pieces of data which both are String data and not nulls. I want to use the same report in a Visual Basic.Net 2003 program. I can pull the report onto the form and it runs wonderfully. I want to make it run programatically with out prompting for the user to key in the parameters. I can supply them from an existing data file. I have tried many things but have lacked the solution.
How can I pass the parameters from VB.Net 2003 to the stored procedure which runs the Crystal Report with in the VB.Net 2003 program.
I appreciate all help and comments.
Can this be done or do I need to just re-write the report in VB.Net 2003?
Thanks,
Norman

Hi, Norman;
It sure is possible to pass parameters to a Stored Procedure via our .NET SDK.
Have a look at these samples:
https://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/9043bbbc-ae66-2b10-ce96-b48f9e25a450
There are samples showing passing parameters.

Multithreading and stored procedures

Hi,
Does anyone know of any problems with calling a stored procedure that returns a reference cursor in a multithreading application? In other words, if I have multiple threads calling the same stored procedure is the reference cursor guarenteed to be unique to each thread/thread safe?
Thanks in advance,

That should work fine and each call will get a separate ref cursor as long as the app is written properly and is managing it's threads anbd handles properly. Are you seeing some behaviour that suggests this is not the case?

Oracle 8i and stored procedures

Hi I was hoping someone could point me to the right direction here.
I have been using SQL server before and often use stored procedures. I understand that if you want to use stored procedures you will use the CallableStatement object and the prepareCall method of the Connection object like so:
let's say my stored proc has 2 number parameters:
CallableStatement cs = con.prepareCall( " { call <stored_proc_name> (?, ?) } );
cs.getString(1, 1);
cs.getString(2, 2);
ResultSet rs = cs.executeQuery( );
where con is my connection object that i used to connect to my database. So far am I right with the following code?
But my problem is I have to use Oracle 8i. So what is the equivalent of SQL server stored procs in Oracle? Is it functions? Procedures? Or Java Stored Procedures? I have been reading all these sites and the forums for ideas but still haev no clue what approach I should take
I have managed to connect to my db using the thin drivers and have successfully passed SQL statements. Although, I don't want to pass SQL statements, I want to use stored procedures. With SQL server I would create all my stored procedures and use my beans to call these stored procedures. So as a new user of Oracle 8i coming form SQL server, what approach do I use and how?
Thanks in advance for all the help!

Alright well looks like I'm stuck now.
This seems more like a PL\SQL question though. If I want to return 2 or more values do I use function or a procedure? here's the code I made:
CREATE OR REPLACE FUNCTION sign_in(username VARCHAR(20), userpassword VARCHAR(20))
RETURN NUMBER IS id_num NUMBER, user_type VARCHAR(1);
BEGIN
SELECT * INTO id_num, user_type
FROM ID_MASTER idm, PERSON prs
WHERE USERNAME = username
AND USER_PASSWORD = userpassword
AND idm.ID_NUM = prs.ID_NUM;
RETURN id_num, user_type;
END;
now according to Oracle this is an invalid function. But the error message doesn't say much. Basically I want to pass 2 parameters to use for a query and return 2 variables from the result of the query. Am I suppose to use a procedure?
If I pass paramters do which string do I use to prepareCall: "{ ? = CALL sign_in (?, ?) }" or do I use the "{ CALL sign_in (?, ?) }"
But my problem right now is how to make the proper stored procedure. I'd be very much obliged to anyone who can give a sample. Thank you all for your time!

Prepared Statement and Stored Procedure..

I have about 200 SQL statement in my Java application
I have two options either to convert into
Stored procedures
or to convert into prepared statement ....
Please guide me which options should be best....
I need difference
1)in term of speed.
2)Memory..

club your statements on the basis of related functionalities and change it to stored procedures as it will redudce no. of calls to the database and will be faster to fetch data in one go and even reduce the memory requirements.

Prepared Statement and Stored Procedure difference?

For SQL in my web applications I use PreparedStatement object alot in my JDBC working with Oracle 9i.
I also heard the term Stored Procedure. What is the difference between Stored Procedure and Prepared Statement?

I am new to java programming, can anybody explain
what exactly precompiled means
Thank you
PalspaceWhat does you subject line have to do with your question?
The difference between a stored proc and a prepared statement is mainly this.
A stored proc is stored in the database server permanently and can be used and re-used from a different connections.
A PreparedStatement is not valid across connections.
Stored procs are almost always precompiled. (I am just hedging a bit here just in case but you can consider it 100%)
PreparedStatements MAY be precompiled. Hard to say.
Precompiling means at least one of and perhaps all of the following depending on the database
- The parsing of the SQL statement
- The checking of the SQL against the data dictionary to ensure that the tables and columns referenced actually exist
- The preparation of a query plan
Last but not least Stored procedures may (and often do) contain more than simple queries but are in fact relatively complex programs written in a DB specific language (an offshoot of SQL of some sort).
