Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.

How to access complex data type from a soap web services?

hello
can u please tell me how can i access complex data type from a soap web service from jdeveloper 10g
Jdeveloper generates 3 classes
serviceStub
getproperties
response
i have to retreview the data which is a complex data type it gives some
unknown type. and the return value is a key-value pair data type .
regards
vs

After you create the partner link and the invoke (to create the variables), change the element type of the response message to the complex type definition of your collection that appears in the XSD. You can do the same thing if you want to change the element type of the payload of the request message as well.

Data types used in a sub VI - selecting the correct input and output types?

data types used in a sub VI - selecting the correct input and output types?
I can never work out how to choose an input or output format for Subvi's.
I want to create a SubVI for the code in red. I needs an VI Server Reference compatible input and an output that goes to a waveform.
Thanks in advance.

GerdW,
I realise now I have taken us in the wrong direction. apologies for that.
History, this is not my code and I do not own the process and NOT my preferred method of using it. I was looking for a simple way to make subtle changes.
What we do - We use these programs to collect data from typically 6 pressures and 6 temperature probes and capture RS232 / USB VISA strings from sensors.
So every few weeks / months or up to a year we rearrange each sensor location to suit the new process. I did not write the code. I cannot change the procedure too much without resistance.
So headers in the CSV file have the DaqMX string passed through the code. Great.
Other data to the CSV file comes from calculations or extracted from the VISA string. Hence why we have headers with "Untitled 1 ()". These values also go to a History Chart.
So I was looking for a simple way to read the the local variable label as it is always linked to the front page indicator. People can cope with editing the indicator label, save the VI and hit run.
TL;DR - GerdW is now a psychologist.

Accessing oracle data types of a different schema

I am having trouble accessing the Oracle data types in a stored procedure. The owner of the stored procedures and the oracle data types is "ODSCUST". I am trying to access this using "CUSTOM" ID from my java program. Recently our DBAs have made a change in schema owners so the ID loging into the Oracle instance is not the owner of the data types or the stored procedures. The "CUSTOM" user has the grants to access all the types and stored procedures. There are also public synonymns created for the oracle data types and stored procedure.
Here is a snipit of the code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
String user="custom";
String password="test";
String database="sbpair11";
Connection conn = DriverManager.getConnection
("jdbc:oracle:oci:@" + database, user, password);
OracleCallableStatement stmt = (OracleCallableStatement)conn.prepareCall( "begin ods_cust.retrieveCustPrflData(?, ?, ?, ?, ?, ?, ?); end;" );
stmt.setString( 1, "5592556485");
stmt.registerOutParameter( 2, OracleTypes.STRUCT, "KSCOPEACCOUNT" );
stmt.registerOutParameter( 3, OracleTypes.ARRAY, "KSCOPERSUUSOCARRAY" );
stmt.registerOutParameter( 4, OracleTypes.ARRAY, "KSCOPECUTADDRARRAY" );
stmt.registerOutParameter( 5, OracleTypes.STRUCT, "KSCOPECONTACT" );
stmt.registerOutParameter( 6, OracleTypes.STRUCT, "KSCOPEPROFILE" );
stmt.registerOutParameter( 7, OracleTypes.ARRAY, "KSCOPEEMAILARRAY" );
stmt.executeUpdate();
Here is the response I get back when I run the program:
Exception in thread "main" java.sql.SQLException: ORA-04043: object "CUSTOM"."KSCOPEACCOUNT" does not exist
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)

at Array5.main(Array5.java:40)
Note:
When I do a "desc KSCOPEACCOUNT" or "desc CUSTOM.KSCOPEACCOUNT" in sqlplus as the "CUSTOM" id it works but not from Java. Initially I was using the JDBC thin driver but was recomended to switch to OCI which still didn't resolve this issue.

Way too little info here for a definite conclusion.
Some thoughts:
1.) Did you take down the database when you were moving the datafiles? If so, is this the first time the batch job is running since the move? If so, perhaps the cache is cold?
2.) How much physical I/O is the batch job doing? Has the volume of physical I/O changed significantly after the move? What are the characteristics of the lun on which the newly mounted filesystem is built? Is it a smaller number of spindles than before?
Ultimately, you need to profile the batch process, and determine where the most time is being consumed.

Issue is De-serializing nested date type using Axiss 1.4

We are using Axis 1.4 and face issue during deserialization in handling date types. The scenario is explained below. I couldn’t find enough information on net on below and hence asking question to the apache team. Please note when we switch to Axis 2, issue is not seen. Upgrading may not be a simple option for us as of now, and hence I was evaluating possible workarounds or solution if any.
The XSD contains type “DateofBirthType” which is of type xsd:date
Child XSDs contains element “DateofBirth” of type “DateOfBirthType”
When Java client invokes the web service, IllegalArgumentException is seen while de-serializing this “DateOfBirthType” element. If we remove “DateOfBirthType” and map it directly to xsd:date type all works fine.
We have generated the stub using Axis 1.4 and trying to access the RetrieveIndividualCustInformation operation through stub, but getting the (IllegalArgumentException) while axis tries to deserialize the response for all the fields having data types as date which is indirectly mapped (nested mapping) as shown below.
e.g. IndividualInfo-----DateOfBirth(Type—DateOfbirth ---Which is of Type Date)-_you will face illegal argument exception.
So, when we changed the type to simple date (not nested),then it worked fine. So it confirms that this problem is only for type date which is clearly seen in Axis 1.4 client.
Please let me know if anyone faces similar/same issue or even know any such issue already persists and there are no possible workarounds and/or fixes for this. In that case we can put up case to migrate to Axis2.
Please reply ASAP.

Hi, Shank,
My guess is that you want:
, dense_rank () over (order by tmstp desc) AS rn RANK means you'll skip numbers when there's a tie. For example, if 3 rows all have the exact same latest tmstp, all 3 rows would be assigned number 1, RANK would assign 4 to the next row, but DENSE_RANK assigns 2.
"PARTITION BY x" means that you want a separate series of numbers (starting with 1) for every value of x. If you want just one series of numbers for the whole result set, then don't use a PARTITION BY clause at all. (PARTITION BY is never required.)
Maybe you wnat to PARTITON BY cd. I can't tell without some sample data, and an explanation of why you want the given results from that data.
You certainly don't want to PARTITION BY the same expression that you ORDER BY; that just means all rows tie for #1.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Simplify the problem as much as possible.
Always say which version of Oracle you're using.

Problem accessing basic data types

Hi,
I am a newbie at using JNI so please don't mind if I am asking something trivial.
I have a JNI wrapper for a native C code. The C code is a Gtk+ application using GLib library. This library has it's own basic data types. For example, "gchar" corresponding to "char". I have generated the JNI Wrappers using the tool named "Swig" which is an interface between the C and other programming languages such as Java. What Swig has come up with is since "gchar" is not understood by it as "char" so it has taken the "gchar" as come Reference Type and generated another class for it. And instead of accepting simple char it is expecting a long.
Even if I pass a numerical value like 11111 after instantiating this newly generated gchar class while running the program the JVM is crashing complaining SIGSEGV recieved from the underlying libraries.
I am confused first of all since the error is not understood and secondly how can I tell the JNI that gchar is similar to char.
What approach should I follow to solve the problem that I am facing? Any feedback on this will be appreciated.
Thanks & Regards

At run time you can see all the data........ like what i have shown...
but if you clearly see, DATE will be in the internal format..but if you print it, it will be in dd:mm:yyyy
can you suggest me if i have a dynamic field symbol (table data) ,,,, How can i convert data types dynamically..
if it is a static internal table i am achieving with WRITE TO statement.....but i have huge data in field symbols...
Instead of all these , please specify the exact problem your are facing . What is it with date field ? . In SAP while printing the internal format will be converted to external. What is your requirement with this date field?
My output looks some thing like this:
04 36876 15.09.2011 39600 1999
06 36960 15.09.2011 39600 2632
07 36874 15.09.2011 39541 9232
My expected output
04 36.876 15.09.2011 39.600 1.999
06 36.960 15.09.2011 39.600 2.632
07 36.874 15.09.2011 39.541 9.232
I dont see any problems mentioned in your date field. Both your actual and expected outputs reflects the same in date field.
In SCN you will only get solutions if your question is precise.

How can I retrieve a LONG data type using ADO

In VB I am using an ADODB object to retrieve data from an Oracle table that has a LONG data type column...
specifically: SELECT TRIGGER_BODY FROM USER_TRIGGERS WHERE TRIGGER_NAME = 'MYTRIGGER'
I have tried using the GETCHUNK method but it only returns the first 150 or so characters no matter how
many times I call it???? here is the sample code I'm using........
Dim Cn As ADODB.Connection, Rs As ADODB.Recordset, SQL As String
Dim sChunk() As Byte
Set Cn = New ADODB.Connection
Set Rs = New ADODB.Recordset
Cn.CursorLocation = adUseServer
Cn.Open "Provider=OraOLEDB.Oracle.1;Password=hrzadmin;Persist Security
Info=True;UserID=hadmin;Data Source=xxx.local"
SQL = "SELECT trigger_body from user_triggers where trigger_name = 'MYTRIGGER'"
Rs.Open SQL, Cn, adOpenStatic, adLockReadOnly
Debug.Print Rs!trigger_name
Debug.Print Rs!trigger_body
sChunk = rs.Fields("trigger_body").GetChunk(500)
Debug.Print sChunk

I have a similar code which works for chunk size >400,
The image I am trying to retrieve is huge so the chunksize is also more.
Did you try with any non meta table?
For your reference I am pasting my application code below.
Hope it helps.

Querying a field of Date type using JPQL

How can i do a JPA Query passing a date whithout using the setParameter method of the Query interface? Something like this:
SELECT entityX FROM EntityX entityX WHERE entityX.date = to_date('mm-DD-yyyy','01-01-2007')
Thanks!
Giuliano Lins

it is not possible to do date.
I have encountered that problems too.
Maybe you should use createNativeQuery method
to_date function is used in PL/SQL, not in JPQL

PS.Shakeer Hussain

Hi PS.Shakeer Hussain,
In Excel, we store these data in excel is string type. Based on your code, it is dataTime type. So if fails when compare with dataTime and string.
Please try the following code, Useing DateTime.ToOADate Method to convert to the equivalent OLE Automation date. It works fine on my side.
OleDbDataAdapter dbAdapter = new OleDbDataAdapter("select * from [Sheet1$] WHERE createdDate < "+DateTime.Parse("3/29/2015").ToOADate(), connExcel);

Problem with custom validated data types using domain on 11g

Hi,
I ' m on a migration process from 10 to 11 and I notice that a custom domain didn't work correctly anymore
to be more specific every time that I was submiting a page a was getting an error cannot convert from myclass to oracle.jbo.domain.String
I search the forum and I saw a similar problem
Cannot convert type class java.lang.String to class oracle.jbo.domain.Clob
at which Frank says that it is a known bug and suggests a work around.
I use the workaround and it worked but some more issues came up:
1. If the validation fails I get the error that I throw at the validate method not in a popup with just my message
but in the whole window with the whole error stack, meaning that my custom validation is not handled like native ADF validation errors by
the framework (at 10.1.3.4 worked OK)
2 If i dont give a value at the attribute in the validation phase mdata variable is not null but is length is zero (at 10.1.3.4 its value was null)
public class AFM implements DomainInterface, Serializable {
public AFM(String val) {
mData = new String(val);
validate();
private String mData;
protected void validate() {
// ### Implement custom domain validation logic here. ###
mData==null // returns false
mData.length()==0 // returns true
3. Can i force validation only for new or updated values? I saw that the validation process is taking place every time a row is fetched.
This is not only a performance issue, the bigger problem is that if a fetched from the DB value fails the validation an error is return but the
user cannot change the value to correct it.

Excel data filtration using oledb from huge excel files size approx (200mb) using c# (ADO)

hi,
My ado application requires to read data from one xlsx file(Approx 10-20MB min) and then process the data row by row and compare with
another xlsx file( approx size 250 MB min) containing over 1000000 rows with 63 columns (work like database).
when i try to read the database file (250 MB) and run the oledb data queries on it, it's working so strange, its only give the first matched data from the database file. but if i opened that xlsx database file in office excel and then run my application
its return all matched data from the database file without changing any code.
i already checked my dataquery its working fine in server Explorer and returns the complete result.
this process also very time consuming ,
i already tried openxml sax mathod to resolve the performance issue as well, but its not worked too. even it takes more time compare to oledb to read the excel.
i also have two another issues in my application,
1. sometime oledb returns an exception 'System resource exceeded' and
2. some time return 'internal ole automation error' .
i also tried google to resolve these issue but i didn't find any solution for my problem.
is there any solution to resolve these issues? please help me. any suggestion appreciated but please remember one thing i can't change any xlsx table format because i don't have rights, these xlsx files automatically generated by another tools by our
sourcing partners.
thanks.

Or, if you don't have SSIS, do Bulk Insert by looping through the files. Let's say the files have something in common, like a date in the name of the file. Simply run this SQL Server script . . .
DECLARE @intFlag
INT
SET @intFlag
= 1
WHILE (@intFlag
<=48)
BEGIN
PRINT @intFlag
declare @fullpath1
varchar(1000)
select @fullpath1
= '''\\ftp\your_path\'
+ convert(varchar,
getdate()- @intFlag
, 112)
+ '_your_file.txt'''
declare @cmd1
nvarchar(1000)
select @cmd1
= 'bulk insert [dbo].[your_table] from '
+ @fullpath1 +
' with (FIELDTERMINATOR = ''\t'', FIRSTROW = 2, ROWTERMINATOR=''0x0a'')'
exec (@cmd1)
SET @intFlag
= @intFlag + 1
END
GO
