OracleXADataSource and Custom SQL mappings

Hi.
In WLS 7 SP4, custom SQL types worked fine with my datasource, which was configured with a connection pool whose driver was OracleConnection. I changed the pool driver to OracleXADataSource because of a new requirement, and set up two new TxDataSources and an extra connection pool for the second DB, as directed by the BEA e-docs. Everything deployed fine but I ran into this problem: Connection.getTypeMap() returns null from the TxDataSource. Creating a new Map and passing it as parameter to setTypeMap() won't work.
Am I missing some additional configuration in WLS/Oracle DB or can't custom SQL types be used with OracleXADataSource?
Just in case: the original DB is Oracle 9i, which has all the custom types defined. The new DB is Oracle 8i, which does not use any custom types at all.
Any hint to this problem will be greatly appreciated.

Hello,
Typically CR queries the database and the client tells CR what the field type is. If there are any types we can't match we usually convert it to a String type but it all depends on the version of Crystal Reports you are using.
I'm not familiar with Netezza so I can't help you with specifics.
All I can suggest is to try creating a report and if you have a problem then post your question with Specific details and any errors generated.
Thank you

Custom sql mappings

Hi,
Is it possible to model associations between classes that are not foreign key based, but rather, arbitrary SQL? How about class attributes that are a PL/SQL call or a subselect? How is this done? What kind of mapping would this be? It seems to me that the many to one, one to one and direct to field mapping editors only let me pick columns, not PL/SQL expressions.
Thanks!
Calin

The mapping editor does not provide support for
providing custom SQL or a stored procedure within
your mapping. You can do this through code by
customizing the selection query on the mapping to use
either a SQLCall or a StoredProcedureCall.
This is typically configured through the use of a
descriptor after-load method. Within our employee
example included in the
[url=http://www.oracle.com/technology/products/ias/top
link/examples/index.html]Foundation Examples.A very trivial example of customizing the SQL for a
1:1 mapping would look like:
public static void
afterLoadEmployee(ClassDescriptor descriptor) {
OneToOneMapping mapping =
OneToOneMapping)descriptor.getMappingForAttributeName(
"address");
mapping.setSelectionSQLString("SELECT * FROM ADDRESS
WHERE ADDRESS_ID = #ADDR_ID");
de]
DougI tried this but I get a NullPointerException when this is used on a one to many mapping (the additional caveat is that I have turned on useBatchReading. There was no setSelectionSqlString. So I used setSQLString.
there was 1 error:

Interactive Reporting and Custom SQL

I have SQL that works in TOAD and I'd like to copy it directly into IR; however, it appears that the custom SQL feature only allows you to "customize" the FROM, WHERE, etc parts of the SELECT statement and not the database fields that are directly after the SELECT. For example, the code below works in TOAD:
SELECT cr_type,
LPAD(SUBSTR(CR_NUM,1,5),5) CR,
TITLE,
nvl(sum(decode(a.employee_Id,1234,hours)),0) DL,
nvl(sum(decode(a.employee_Id,5678,hours)),0) MF,
nvl(sum(decode(a.employee_Id,9101,hours)),0) HM, etc
I am having a hard time re-creating this code in IR. I finally did manage to come close to what TOAD gives me; however, is there an easier way to use the custom SQL to just cut and paste the entire SQL statement that works in TOAD and put it into IR?
Thanks.
Terri T.

You can Import the complete SQL String into IR, but you will not be able to modify it once it is in IR.
You can create Computed Items in the Request Line for each of the SQL segments, i know it is labor some but it works. Just make sure that the Data Type is as you want it - Options Tab.
Another Option is to have the SQL String you have turned into a view on the database and query it that way.

Error when use stored procedure in Named Query and Custom SQL

This is a toplink development on Jdev 1013. A package with a function is created which returns a "ref cursor" in a oracle 9i database. I tried to access the function in jdev toplink descriptor editor either through custom sql (Readall) or a named query (procedureTest) and I got java.sql.SQLException: SQL string is not Query. Note: I am NOT talking about programatic storedprocedurecall object.
The client access code is following (where error was thrown):
results = (Collection) session.executeQuery("procedureTest", WuTest.class);

Any responses? Thanks.

Conditions and Custom SQL in Webi SDK

I'm porting an application written using REBean in BusinessObjects 3.1 to use the new Webi RESTful SDK. I'm currently working with BI 4.1 SP4. There are two things that I could do in easily REBean that I am having a hard time figuring out in the new SDK.
View condition information on a data provider -- In REBean you could use the ConditionContainer object to navigate the condition tree on a query and see all of the query's conditions, including the object name and operator. This information doesn't seem to be included in the Data Provider Details web service so I'm not sure where to find it. Am I missing something? Is the Query Specification the only place where this information is available?
Identify whether a query is using custom SQL -- As far as I know, this is different than Freehand SQL data providers which are supported in the new SDK. In REBean you could use SQLDataProvider.isCustomSQL() to discover if a particular query had the Custom SQL radio button selected in the universe query panel. Again, this information doesn't seem to be included on the Data Provider Details web service. How can I tell if a query is using Custom SQL in the new Web Services SDK?
Thanks,
Ryan

Hi Ryan,
Both of your questions are possible.
1. you can get the queriesTree and conditions, including names and operators, from the specification of the dataprovider with the following request (text/xml)
GET /raylight/v1/documents/<docId>/dataproviders/<dataproviderId>/specification
2. you can identify custom SQL by returning the queryPlan of the dataprovider (application/xml)
GET /raylight/v1/documents/<docId>/dataproviders/<dataproviderId>/queryplan
Response:
      <queryplan editable="true" custom="true">
         <statement index="1">
             your customized SQL
         </statement>
      </queryplan>
I hope this helps,
Dan

How to operate multiple querys using DB Adapter and 'Execute Custom SQL'

I have a requirment that I need to create database adapter in your BPEL process with 'Execute Custom SQL' to operate multiple query in DB in one atomic
here are the details:
inbound request:
<ns1:Query_bpelProcessRequest>
<ns1:input>
<ns1:ItemDetail>
<ns1:ItemID>1123DDDS</ns1:ItemID>
</ns1:ItemDetail>
<ns1:ItemDetail>
<ns1:ItemID>1126EWWA</ns1:ItemID>
</ns1:ItemDetail>
<ns1:ItemDetail>
<ns1:ItemID>11208FSAA</ns1:ItemID>
</ns1:ItemDetail>
</ns1:input>
</ns1:Query_bpelProcessRequest>
I use for-each fuction in XSLT to mapping the all ItemID value:
<xsl:template match="/">
<xsl:for-each select="/tns:Query_bpelProcessRequest/tns:input/tns:ItemDetail">
<ns1:QueryFromDB_Input>
<ns1:ItemID>
<xsl:value-of select="tns:ItemID"/>
</ns1:ItemID>
</ns1:QueryFromDB_Input>
</xsl:for-each>
</xsl:template>
and in DB Adapter I use the 'Execute Custom SQL' to query the CONTENT value according the ItemID value:
select distinct CONTENT from agile.item where ITEM_NUMBER=’<ItemID>’
However, in the result, It only query the first item value for <ns1:ItemID>1123DDDS</ns1:ItemID>
<<QueryFromDB_InputVariable><part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="QueryFromDB_Input_msg">
<QueryFromDB_Input xmlns:ns1="http://xmlns.oracle.com/pcbpel/adapter/db/QueryFromDB" xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/QueryFromDB">

</QueryFromDB_Input>
</part></QueryFromDB_InputVariable>

<ITEM_NUMBER>1123DDDS</ITEM_NUMBER>
<CONTENT >SJIFESSFFJ</CONTENT >
</QueryFromDB_Output>
</QueryFromDB_OutputCollection>
</part></QueryFromDB_OutputVariable>
the other two querys are not operated.
what can I do to operate multiple querys??
Thanks

Hi Rod,
I are using while loop and assign array inputvalue to the inputvarable of DBadapter now, but actually it doesn't work.
Throw expection

Please check the BPEL source at line number "89" and verify the part and xpath query /client:ItemsQuery_bpelProcessRequest/client:input/client:inputDetail/client:ProductID["ItemIndex"].

I use {} instead of [] for array, because [] seams not reveal in this message board
seems I can't assign array values to the DB inputvalue, Are there any solutions for this ?
I still haven't found any way for operating multiple querys using DB Adapter.

DB polling using custom SQL in SOA Suite 11g

Hi,
We are trying to poll records from a database using custom sql. But all the records in the table are being picked up at the same time and not as per the polling frequency set in the adapter.
Below is the configuration from the .jca file:
<endpoint-activation portType="II_ptt" operation="receive">
<activation-spec className="oracle.tip.adapter.db.DBActivationSpec">
<property name="DescriptorName" value="II.OrderRequest"/>
<property name="QueryName" value="IISelect"/>
<property name="MappingsMetaDataURL" value="II-or-mappings.xml"/>
<property name="PollingStrategy" value="DeletePollingStrategy"/>
<property name="PollingInterval" value="60"/>
<property name="MaxRaiseSize" value="10"/>
<property name="MaxTransactionSize" value="10"/>
<property name="SequencingColumn" value="REQUEST_SAK"/>
<property name="NumberOfThreads" value="1"/>
<property name="ReturnSingleResultSet" value="false"/>
<property name="DeleteDetailRows" value="false"/>
</activation-spec>
</endpoint-activation>
Please let us know if anything else needs to be set to enable the polling as per the frequency in the adapter.
Thanks.

As the link from Anuj said, you need to also configure 'Distributed Polling' in the wizard. This speed limit trick will no longer work out of the box in 11.1.1.3 on, you will also have to set usesSkipLocking="false" in your DbAdapter connection pool definition. Skip locking eliminates the locking contention issue, so this primitive kind of load balancing is no longer needed in that case.
Thanks
Steve

Help required to fit custom SQL in mapping.xml file for complex queries.
Thanks,
Arun Jadhav.

"Execuite Custom SQL" in DB adapter and you'l get it.
But in this case you'll have to implement your own polling strategy (if you need one).
If you want to use one of the predefined polling strategy you should use "Poll for New or Changed records" and import all the tables you use and connect them in wizard.

Discoverer Custom SQL Report with Group By,Having

Hi all,
I'm working with Discoverer 4.1.41.05 and retrieve data from Oracle HRMS.
I want to create a report based on a custom SQL Folder in Discoverer Administration to solve the following scenario:
SELECT EMPLOYEE_NUMBER FROM PER_ALL_PEOPLE_F
MINUS
SELECT EMPLOYEE_NUMBER FROM PER_ALL_PEOPLE_F,PER_EVENTS, PER_BOOKINGS
GROUP BY EMPLOYEE_NUMBER
HAVING SUM(PER_EVENTS.ATTRIBUTE1) >= 10)
The problem is when I run the sql from SQL*Plus is working fine producing the correct result.
When I create the Custom Folder and create a Discoverer report based on it I retrieve all employees since the second select statement retrieve no rows!
Does anyone has any idea how I can solve this problem or if there is another way to create this scenario?
Any feedback is much appreciated.
Thanking you in advance.
Elena

Hi Elena,
I think you are missing some joins, you could try something like:
SELECT EMPLOYEE_NUMBER FROM PER_ALL_PEOPLE_F p
WHERE NOT EXISTS
(SELECT NULL
FROM PER_EVENTS e, PER_BOOKINGS b
WHERE b.person_id = p.person_id
AND e.event_id = b.event_id
GROUP BY b.person_id
HAVING SUM(e.ATTRIBUTE1) >= 10)

* How can I use an Dual table in OWB mapping?
* Can I write Customized SQL query in OWB? How can I achieve this in a Mapping?
Thanks in Advance

Hi Niels,
As I'm sure you know, the conundrum is that Reports doesn't know how many total pages there will be in the report until it is all done formatting, which is too late for your needs. So, one classical solution to this problem is to run the report twice, storing the total number of pages in the database using a format trigger, and throwing away the output from the first run when you don't know the total number of pages.
Alternatively, you could define a report layout so that the number of pages in the output is completely predictable based upon, say, the number of rows in the main query. E.g., set a limit of one, two, ... rows per page, and then you'll know how many pages there will be simply because you can count the rows in a separate query.
Hope this helps...

How to specify custom SQL in polling db adapter with logical delete option

Hi all,
I am writing a SOA composite app using JDeveloper SOA Suite 11.1.1.4 connecting to a SQL Server db using a polling DB Adapter with the logical delete option to send data to a BPEL process.
I have requirements which go beyond what is supported in the JDeveloper UI for DB Adapter polling options, namely:
* update more than one column to mark each row read, and
* specify different SQL for the logical delete operation based on whether bpel processing of the data polled was successful or not.
A complicating factor is that the polling involves two tables. Here is my full use-case:
1) Polling will select data derived from two tables: e.g. 'headers' and 'details' simplified for this example:
table: headers
hid - primary key
name - data label
status - 'unprocessed', 'processed', or 'error'
processedDate - null when data is loaded, set to current datetime when row is processed
table: details
hid - foreign key pointed at header.hid
attr - data attribute name
value - value of data attribute
2) There is a many:1 relationship between detail and header rows through the hid columns. The db adapter polling SELECT shall return results from an outer join consisting of one header row and the associated detail rows where header.status = 'unprocessed' and header.hid = details.hid. (This is supported by the Jdeveloper UI)
3) The polled data will be sent to be processed by a bpel process:
3.1) If the bpel processing succeeds, the logical delete (UPDATE) operation shall set header.status = 'processed', and header.processedDate = 'getdate()'.
3.2) If bpel processing fails (e.g. hits a data error while processing the selected data) the logical delete (UPDATE) operation shall set header.status = 'failed', header.processedDate = 'getdate()', and header.errorMsg = '{some text returned from bpel}'.
Several parts of #3 are not supported by the JDeveloper UI: updating multiple columns to mark the row processed, using getdate() to populate a value of one of those column updates, doing different update operations based on the results of the BPEL processing of the data (success or error), and using data obtained from BPEL processing as a value of those column updates (error message).
I have found examples which describe specifying custom SQL using the polling delete option to create a template then modifying the toplink file(s) to specify custom select and update SQL to implement a logical delete. (e.g. http://dlimiter.wordpress.com/2009/11/05/advanced-logic-in-oracle-bpel-polling-database-adapter/ and http://myexperienceswithsoa.blogspot.com/2010/06/db-adapter-polling-tricks.html). But none of them match what I've got in my project, in the first case because maybe because I'm using a higher version of JDeveloper, and in the second I think because in my case two tables are involved.
Any suggestions would be appreciated. Thanks, John

Hi John,
You've raised a good scenario.
First of all let me say that the purpose of the DB polling transaction, is to have an option to initiate a process from a DB table/view and not to update multiple fields in a table (or have other complex manipulation on the table).
So, when choose to update a field in a record, after reading it, you are "telling" the engine not to poll this record again. Sure, i guess you can find a solution/workaround for it, but I don't think this is the way....
The question now is what to do?
You can have another DB adapter where you can update the data after finishing the process. In that case, after reading the data (on polling transaction) - update the header.status = 'processed' for example, and after processing the selected data update the rest of the fields.
Hope it make some sense to you.

Batch Reading with Custom SQL

Hello,
Queries
1. Is it possible to use Batch Reading in conjunction with Custom Stored Procs/ SQL?
2. Is it possible to map an attribute to a SQL expression (like in Hibernate we have formula columns mapped using the formula* property)?
Background
1. We use Toplink 11g (11.1.1.0.1) (not EclipseLink) in our application and are controlling mapping using XML files (not annotations).
2. We are migrating a legacy application with most of its data retreival logic present in stored procedures to Java.
3. I am effectively a newbie to Toplink.
Scenario
1. We have a deep class heirarchy with ClassA+ at the following having a one-to-many relation with ClassB+ and ClassB+ having a one-to-many relation with ClassC+ and so on and so forth.
2. For each of these classes the data retreival logic is present in stored procedures (coming from the legacy application) containing not so simple queries.
3. Also there are a quite a few attributes that actually represent computed values (computed and returned from the stored procedure). Also the logic for computing the values are not simple either.
4. So to make things easy we configured toplink to use the stored procedures to retreive data for objects of ClassA+, ClassB+ and ClassC+.
5. But since the class heirarchy was deep, we ended up firing too many stored procedure calls to the database.
6. We thought we could use the Batch Reading feature to help with this, but I have come across documentation that says that it wont work if you override toplink's queries with stored procedures.
7. I wrote some sample code to determine this and for the heirarchy shown above it uses the speicifed Custom procedure (I also tried replacing the stored procs with custom SQL, but the behavior is the same) for ClassA+ and ClassB+, but for ClassC+ and below it resorts to its own generated SQL.
8. This is a problem because the generated SQL contains the names of the computed columns which is not present in the underlying source tables.
Thanks
Arvind

Batch reading is not supported with custom SQL or stored procedures.
Join fetching is though, so you may wish to investigate that (you need to ensure you return the correct data from the stored procedure).
