XSU and CURSOR expression in the sql query

Platform: oracle 8.X on ibm aix and java client code from
windows NT.
JDBC DRIVER: JDBC Oracle thin driver version 1.2.
when i execute a Sql satement with Cursor expression from the
java client code with XSU it returns an XML DOM But if the
CURSOR EXPRESSION IN THE SQL QUERY RETURNS EMPTY ROWS i get
back an error node with "ORA-01001 Invalid Cursor" error
message.i had aslo set the setNullAttributes(true) property
on oraclexmlquery.
Interestingly, if i exceute the same query in the SQL plus
it returns the column names with no rows.
is there any way where i can get xml document with table
structure, when there are no rows instead of ORA error message.

Ok.
I assume that you have for one activity several asset PNR and for one asset several activity.
The factPNR is on this way a real bridge table. It's a way to be able to design a many-to-many relationship.
Have a look here for more detail on how to build a many-to-many relationship :
http://gerardnico.com/wiki/dw/data_quality/relationships#many-to-many
Therefore I assume that you want this design :
DimActivity -< FactActivity >- < FactPNR >- DimPNR and you will have :
DimActivity -< FactActivity >- < BridgeTable >- DimPNR How to build your bridge table ?
In the physical layer, :
* create a new table BridgeActivityPNR, open it and select "statement"
* enter your sql statement
SELECT DISTINCT A.ROW_WID ACTIVIDAD_WID, B.ROW_WID ASSET_WID
FROM W_ACTIVITY_F A,
W_ASSET_D B,
W_SRVREQ_D C,
X_S_CMPT_MTRC_F D,
X_S_ASSET_FEA_D E
WHERE A.X_SRA_SR_ID=C.INTEGRATION_ID AND
C.X_VLG_FLIGHT_ID=D.X_ROW_ID AND
D.X_ROW_ID=E.X_CM_ID AND
E.X_ASSET_ID=B.X_ROW_ID* add two columns in the column tab : ACTIVIDAD_WID and ASSET_WID
* create the physical join with the table FactActivity and DimPNR
* drag and drop in the business model your table BridgeActivityPNR
* in the BMM, create the complex join like this :
DimActivity -< FactActivity >- < BridgeTable >- DimPNR * open your logical bridge table and check the bridge table option.
And you are done if I didn't forget anything.

How does Index fragmentation and statistics affect the sql query performance

Hi,
How does Index fragmentation and statistics affect the sql query performance

How does Index fragmentation and statistics affect the sql query performance
Very simple answer, outdated statistics will lead optimizer to create bad plans which in turn will require more resources and this will impact performance. If index is fragmented ( mainly clustered index,holds true for Non clustred as well) time spent in finding
the value will be more as query would have to search fragmented index to look for data, additional spaces will increase search time.

HOW TO FIND AND CORRECT THE SQL QUERY ERRORS ????

Sometimes I get the errors while executing the sql queries.
I just wanted to know about the various ways by which I can find the sql query errors .
Any suggestions will be deeply appreciated.

If you get the an error from SSMS and you can't comprehend it, you can google the error message and google would always lead you to the correction. Or you can post the error in this forum, people
here are always kind and ready to help :).
If you have any question, feel free to let me know.

Storing the SQL Query results as XML

Hi All,
I have a proc to select all the data from emp table and insert into another table. For some reason it inserts only one column and one record.
I don't have any row limit or skip ...
CREATE OR REPLACE procedure Convert_Data_Into_XML1
as
-- Var Declartion
qryCtx DBMS_XMLGEN.ctxHandle;
result CLOB;
BEGIN
qryCtx := dbms_xmlgen.newContext('SELECT * from emp');
-- set the row header to be EMPLOYEE
DBMS_XMLGEN.setRowTag(qryCtx, 'Employee-ROW');
DBMS_XMLGEN.setRowsetTag(qryCtx, 'Employee-rowset');
LOOP
-- now get the result
result := DBMS_XMLGEN.getXML(qryCtx);
DBMS_OUTPUT.PUT_LINE ('In the Loop');
EXIT WHEN DBMS_XMLGEN.getNumRowsProcessed(qryCtx) = 0;
INSERT INTO temp_clob_tab VALUES (result);
END LOOP;
COMMIT;
--close context
DBMS_XMLGEN.closeContext(qryCtx);
exception
when others then
dbms_output.put_line(TO_CHAR(sqlerrm));
END;
Basically I got this sample proc from Oracle website. As per the website I should be able to store all the records from emp table.
How can I debug this.
Here is the output from SQLPLUS>
SQL> select result from temp_clob_tab;
RESULT
<?xml version="1.0"?>
<Employee-rowset>
<Employee-ROW>
<EMPNO>7369</EMPNO>
>>>>>>>>>>
Thanks in advance

I am able to convert the SQL query output and I am able to store it in a XMLTYPE column.
But the code doesn't work when I took the same code and try to Implement inside a Trigger. The reason I am doing this is, when there is an update or delete, I want to store the whole record as a XMLTYPE doc (before and After). But the code compiles fine, but when I tried to update a record it gives error.
CREATE OR REPLACE TRIGGER INS_UPDDEV_EMP3_F
BEFORE UPDATE OR DELETE ON EMP
FOR EACH ROW
DECLARE
V_DBUSER VARCHAR2(50);
V_CHANGETYPE VARCHAR2(20) := 'INSERT' ;
QRYCTX DBMS_XMLGEN.CTXHANDLE ;
OLDVALUE XMLTYPE;
NEWVALUE XMLTYPE;
BEGIN
IF :OLD.EMPNO <> :NEW.EMPNO or DELETING then
---------- old Value
QRYCTX := DBMS_XMLGEN.NEWCONTEXT ('SELECT :OLD.EMPNO, :OLD.ENAME, :OLD.JOB, :OLD.MGR, :OLD.HIREDATE, :OLD.SAL, :OLD.COMM, :OLD.DEPTNO FROM EMP WHERE EMPNO=:OLD.EMPNO ');
DBMS_XMLGEN.SETROWTAG (QRYCTX, 'DEPTROW');
DBMS_XMLGEN.SETROWSETTAG(QRYCTX, 'DEPTSET');
OLDVALUE := XMLTYPE(DBMS_XMLGEN.GETXML(QRYCTX));
------------------------- new Value
QRYCTX := DBMS_XMLGEN.NEWCONTEXT ('Select * WHERE EMPNO=:NEW.EMPNO '); -- WHERE :OLD.EMPNO
DBMS_XMLGEN.SETROWTAG (QRYCTX, 'DEPTROW');
DBMS_XMLGEN.SETROWSETTAG(QRYCTX, 'DEPTSET');
NEWVALUE := XMLTYPE(DBMS_XMLGEN.GETXML(QRYCTX));
V_CHANGETYPE := 'UPDATE' ;
INSERT INTO ADM_RECAUDITHISTORY VALUES ('table emp', 'fIELD all', OLDVALUE, OLDVALUE,
V_CHANGETYPE , SYSDATE, 'TIGER TRIG');
commit;
END IF;
END;
I am getting the following error while updating the record.
>>>>

Using join and batch reading in the same query

Hi,
I wonder if it is possible to use "Joining" and "batch reading" in the same query.
For example I Have
A -> 1-1 B
A -> 1-1 B
B -> 1-M C
This is the case where I have two separate 1-1 relationships to the same class B from A. Toplink 10.0.3 can manage it nicely through joining.
Now, I would like to read a set of As (with its 2 Bs) and all Cs for each B.
It seems that the following configuration does not work:
A -> 1-1 B (use joining)
A -> 1-1 B (use joining)
B -> 1-M C (Batch read)
Any help would be greatly appreciated
Tony.

James,
Would you be so kind to look at the following code?
Am I formulating it correctly to achieve my desired behavior?
Trip.class -> 1-1 PickupStop
Trip.class -> 1-1 DropoffStop
PickupStop and DropoffStop extend Stop and use same table (STOP)
Stop -> 1-M StopEvents
I would like to fetch all Trips, with their Stops and all StopEvents in 2 queries:
1. Trip joined with Stop
2. Batchread StopEvents
Code:
ReadAllQuery raq = new ReadAllQuery(Trip.class);
Expression qexp1 = new ExpressionBuilder();
Expression qexp2 = new ExpressionBuilder();
raq.addJoinedAttribute("pickupStop");
raq.addJoinedAttribute("dropoffStop");
raq.addBatchReadAttribute(qexp1.get("pickupStop").get("vStopEvents"));
raq.addBatchReadAttribute(qexp2.get("dropoffStop").get("vStopEvents"));

How to view the sql query?

hi,
how to view the sql query formed from the xml structure in the receiver jdbc?

You can view SAP Note at
http://service.sap.com/notes
But you require SMP login ID for this which you should get from your company. The content of the notes are as follows:
Reason and Prerequisites
You are looking for additional parameter settings. There are two possible reasons why a feature is available via the "additional parameters" table in the "advanced mode" section of the configuration, but not as documented parameter in the configuration UI itself:
Category 1: The parameter has been introduced for a patch or a SP upgrade where no UI upgrade and/or documentation upgrade was possible. In this case, the parameter will be moved to the UI and the documentation as soon as possible. The parameter in the "additional parameters" table will be deprecated after this move, but still be working. The parameter belongs to the supported adapter functionality and can be used in all, also productive, scenarios.
Category 2. The parameter has been introduced for testing purposes, proof-of-concept scenarios, as workaround or as pre-released functionality. In this case, the parameter may or may not be moved to the UI and documentation, and the functionality may be changed, replaced or removed. For this parameter category there is no guaranteed support and usage in productive scenarios is not supported.
When you want to use a parameter documented here, please be aware to which category it belongs!
Solution
The following list shows all available parameters of category 1 or 2. Please note:
Parameter names are always case-sensitive! Parameter values may be case-sensitive, this is documented for each parameter.
Parameter names and values as documented below must be used always without quotaton marks ("), if not explicitly stated otherwise.
The default value of a parameter is always chosen that it does not change the standard functionality
JDBC Receiver Adapter Parameters
1. Parameter name: "logSQLStatement"
              Parameter type: boolean
              Parameter value: true for any string value, false only for empty string
              Parameter value default: false (empty String)
              Available with: SP9
              Category: 2
              Description:
              When implementing a scenario with the JDBC receiver adapter, it may be helpful to see which SQL statement is generated by the JDBC adapter from the XI message content for error analysis. Before SP9, this can only be found in the trace of the JDBC adapter if trace level DEBUG is activated. With SP9, the generated SQL statement will be shown in the details page (audit protocol) of the message monitor for each message directly.
              This should be used only during the test phase and not in productive scenarios.

Prateek

How to get cm:search to use the max attribute when creating the SQL query?

When we use the max attribute in the cm:search tag, it does not seem to honor the max attribute when creating the SQL query. However, the result returned from the tag is limited to the number specified by the max attribute. Then the tag seems to work as intended, but the performance will be sub optimal when the SQL query returns unnecessary rows to the application.
We use the cm:search tag to list the latest news (ordered by date), and with the current implementation we have to expect a decrease in performance over time as more news is published. But we can’t live with that. We need to do the constraint in the SQL query, not in the application.
The sortBy attribute of cm:search is translated to “order by” in the SQL query, as expected.
Is it possible to get cm:search to generate the SQL query with an addition of “where rownum <= maxRows”?

Hi Erik,
The behavior of a repository in regards to the search tag's max results parameter is dependent on the underlying repository's implementation. That said, the OOTB repository in WLP does augment the generated SQL to limit the number of rows returned from the database. This is done in the parsing logic. This behavior may differ with other repository implementations.

How to find out which Tables have been accessed without looking at the SQL query ?

Hi,
I would like to know is there a way to find out what queries have been executed and on which tables without looking at the SQL query.
I have an old C++ code which calls some library functions to access the Oracle database. The source code for the library is not available to me yet. The functions selects/updates/deletes and inserts based on some input parameters I give. I do not know which tables it affects. How do I find out the actual SQL query and/or the tables it accesses ? I was told about V$SQL table that
has the most recently executed queries, but
I did'nt see any queries connected to my process.
Could anybody help me on this ?
Thanks

PRECISE/SQL can help you if you have access to it
2nd option can be that turn on SQL_TRACE
Run executable of ur c++ program
it will create a trace file in user_dump_dest
and then using TKPROF u can see all quesries and their plan also.

The SQL query is not executing

Hi
I have the following situation: In a project we designed our reports calling a stored procedure the exits in a MS SQL Server 200 database. The Stored Procedures works fine and when they are used in the report everything works perfectly.
The reports are being made with CR DEsigner 11, when the designer ends them, ha pass them to me and we put them in our java web application. I open them and even preview them since the Crystal Reprots Perspective of Eclipse and I can see the data, so everything to this point is OK.
The problem comes when I change of connection, I'm trying to connect every report to the same host and database, and when the reprot is displayed in the browser there is no data. I profile the SQL commands that are executed when the report is requested and I found that the reprot is not executing the stored procedure.
I guess because i'm connectring the report to the same database and host that was used when the report is created and i'm also passing exactly the same parameters of the stored procedure, then report thinks that it doesn't have executing again becuase it will be the same information.
SO, i wonder if there is a way to request to the report to execute the sql query every time i have to display it.
thanks for any help.

What happens when you try to view the report using a simple viewer.jsp?without changing the connection?
2009-05-25 14:06:09,250 ERROR com.businessobjects.reports.sdk.JRCCommunicationAdapter - detected an exception: Error de conexión: [SQLServer 2000 Driver for JDBC]Error establishing socket.
But the database server is ok, so i think the rpt needs more information to be connect to the database.
Also what happens if you dont use the data bean and give everything there only?
The same, the rpt is not executing the stored procedure.
Did anything change on the RDBMS side? Additional packages, changes to the schema, ownership, etc?
No, the server is ok and the database is ok.
If you configure Log4J logging to DEBUG, you should see the database invokes from the Crystal Java engine, specifically the queries sent and the number of rowsets returned. Do you notice any errors?
I have a problem here with log4j. In my project i'm using spring and with the help of spring i configure log4j, basically with spring is easier to configure log4j.
I'm telling you this because i have log4j working but when my application reaches the code to change the connection to the rerport, log4j dies and stop sending any message to the stdout or to a log file. I haven't since this behavior in any other app o library. So i want to guess i have something wrong with my log4j or maybe with log4j+spring.
So, i remove all the code of spring referring to log4j, but the problem with log4j wasn't solved.
What i will try now is to remove spring from the project.
This is my log4j.properties:
log4j.rootLogger=DEBUG, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

Hi,
This delivers possibly wrong data in MCOD installations.
Depending on Oracle Version and Patchlevel dba_segments does not always have the correct data,
at any time esp. for indexes right after being rebuild parallel (Even in DB02 because it is using USER_SEGMENTS).
Takes a day to get the data back in line (never found out, who did the correction at night, could be RSCOLL00 ?).
Use above statement with "OWNER = " in WHERE for MCOD or connect as schema owner and use USER_SEGMENTS.
Use with
segment_name LIKE '<TABLE_NAME>%'
if you like to see the related indexes as well.
For partitioned objects, a join from dba_tables / dba_indexes to dba_tab_partitions/dba_ind_partitions to dba_segments
might be needed, esp. for hash partitioned tables, depending on how they have been created ( partition names SYS_xxxx).

The bind variables T_SICategory_I is not yet use in the sql query but will be used later so i defined it for the view object.
Is it a reason that the run time check this ? It would be more convenient to set the bind variables early when defining the view object and add them later during the development iteration.

Design-time defined named bind variables can be marked as required, or not.
This is decided by the use in the where clause or in view criteria. In my case the bind variable was not used in where clause neither in view criteria and that causes the error.
May be i would be nice to add a check box (a flag) that enable or disable the bind variables for this checking so we will be able to let it defined even we removed some part of the query corresponding to the corresponding restriction or we defined it earlier for a part of the query that is not yet defined.
In my current case i fully defined the bind variables but would refine my query later ... in that cause i would have to remove this bind variable and loose all the definitions to run this view object.
sorry for my english ...

Modifying the sql query in doDML of entity

I am using Jdev 11.1.1.4.0 and SQLServer Database
I want to modify the sql query in "doDML(int operation, TransactionEvent e)"
I could check what kind of operation like (operation == DML_UPDATE) and do some additional stuff.. But I want to edit the query because of which we entered doDML..
I want to edit the query because when i use SQLServer database with SQLBuilder as SQL92, the update statement will have table alias like "update table <table alias>" which the SQLServer is not recognizing.. So I want to remove that alias from sql query in doDML..

It isn't possible.
However as per the following MSDN page a table alias is fine in an UPDATE statement so are you sure this is your problem?: http://msdn.microsoft.com/en-us/library/aa260662(v=sql.80).aspx

Oscar,
I've read Carys paper and a good paper it is.
The point I was trying to get across is that there should be no rules of thumb. (par this one of course ;) )
It all depends. Should one concentrate on reducing cpu usage on a disk-bound system? Is doing, say, 100 single-block reads from disk faster than doing 100 current mode gets?

I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work

Hi,
I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work
(fault number -2147217900)
I want to search for a value in a ms access table , if it exist i want to update it, if not i want to insert a new row.
Working with LabView 7.1, database con. toolset.
Who can HELP?
Thanks a lot
Marco

Hello,
I think that If exist is not a standar SQL command (I know it exists I think in Oracle and SQL server), MS access doesn't support it, so I think the best way to do it is first make a Select and then either an Update or an insert, sorry...
