Support for Array Binding and PL/SQL tables (IN, INOUT, or OUT)

I have attempted, unsuccessfully, to use array binding in stored procedure/function calls where the sp/sf has parameters that are PL/SQL tables. I have seen the topic floating around in this forum, but I have not seen the explicit questions:
- Does ODP.NET support PL/SQL tables as IN, INOUT or OUT parameters to stored procedures/functions?
- Will any planned ODP.NET release support PL/SQL tables as IN, INOUT or OUT parameters to stored procedures/functions?
I am aware that I can use REF CURSORS to handle the OUT situation, but I need to make a design decision concerning supporting parameters of IN and INOUT PL/SQL tables.
Thanks.
James

You really MUST do this!! - i.e. include support for PL/SQL table parameters (IN INOUT and OUT) in a future release of ODP.NET.
PL/SQL tables are a fundamental type in Oracle stored procedures and you will be preventing a huge number of existing projects from migrating to .NET if you don't acknowledge them as part and parcel of Oracle programming.
I sincerely hope support for PL/SQL table parameters is treated as a serious issue.
Think what a coup it would be for you over Microsoft (who don't currently support PL/SQL tables with their .NET native provider for Oracle and don't look as if they will at least in the short term)!
Please, please, please!

Diference b/w normal tables and pl/sql tables

what is the diference b/w normal tables and pl/sql tables.
already we have tables then what is the purpose of pl/sql tables.
what are the advantages of pl/sql tables compare nor mal tables.

They are memory structures that store data and go away when your program stops running - essentially arrays or "tables" in other programming languages. "normal" ("heap") tables are stored on disk and are persistant - they store data permanently.
already we have tables then what is the purpose of pl/sql tables.Collections are used to store data temporarily in memory, when it will be accessed shortly or repeatedly for fast access. This works best with smaller data sets because if you store too much data in a collection you can run out of memory to use
what are the advantages of pl/sql tables compare nor mal tables.Collections give you faster access to data you need to read more than once during the same application. They work well for fast lookups and for smaller data sets can improve program performance slightly with the use of the bulk collect and forall PL/SQL operators under the right conditions.

Exception Handling for Array Binding

Hi
1)
I am using a Stored Procedure.
I am using array binding and if i am sending an array of count 10 to be inserted in a table and only 9 got inserted,i deliberatly inserted one errorneous record in array, the count returned by ExecuteNonQuery() is 10.Why ?
How can i come to know exact number of rows inserted in table, how can i use Output variables, because the array bind count is 10 so if i add an output parameter it gives error ArrayBind count is wrong....
2)
Is it possible to roll back all the inserts if error occurs in any of the insert by Oracle engine.What it does is it inserts all correct records and leaves the errorneous record and doesn't even throw any exception or any message.
Answer - This can be achieved by using OracleTransaction and don't use Exception handling in procedure otherwise there wont be any exception thrown by procedure which is necessary to detect if an error occured during insert.If you use exception handling OracleEngine will insert correct rows and leave errorneous record and return count of inserted + non inserted records which is wrong.
Please help.

You'll need to encapsulate your validation within it's own block as described below:
-- this will die on the first exception
declare
TYPE T_BADDATA_TEST IS TABLE OF VARCHAR2(1000) INDEX BY binary_integer ;
tbt T_BADDATA_TEST ;
aBadTypeFound exception ;
begin
   tbt(0) := 'a';
   tbt(1) := 'b';
   tbt(2) := 'c';
    for idx in tbt.first..tbt.last loop
      if tbt(idx) = 'b' then
          raise aBadTypeFound ;
      else
          dbms_output.put_line(tbt(idx));
      end if ;
    end loop ;
end ;--encapsulate the exception area in a begin/end block to handle the exception but continue on
declare
TYPE T_BADDATA_TEST IS TABLE OF VARCHAR2(1000) INDEX BY binary_integer ;
tbt T_BADDATA_TEST ;
aBadTypeFound exception ;
begin
   tbt(0) := 'a';
   tbt(1) := 'b';
   tbt(2) := 'c';
    for idx in tbt.first..tbt.last loop
      BEGIN
      if tbt(idx) = 'b' then
          raise aBadTypeFound ;
      else
          dbms_output.put_line(tbt(idx));
      end if ;
      EXCEPTION
        WHEN aBadTypeFound THEN
            dbms_output.put_line(tbt(idx) || ' is bad data');
        WHEN OTHERS THEN
            dbms_output.put_line('exception');
      END ;
    end loop ;

Logic for inserting values from Pl/sql table

Hi I'm using Forms 6i and db 10.2.0.1.0
I am reading an xml file using text_io, and extracting the contents to Pl/sql table.
Suppose, the xml
<?xml version="1.0" encoding="UTF-8" ?>
<XML>
<File name="S2_240463.201002170044.Z">
<BookingEnvelope>
<SenderID>KNPROD</SenderID>
<ReceiverID>NVOCC</ReceiverID>
<Password>TradingPartners</Password>
</BookingEnvelope>
</File>
</XML>From this xml, i'm extracting contents to a table of records, say bk_arr, which look like
Tag                             Val
File name                     S2_240463.201002170044.Z
SenderID                     KNPROD
ReceiverID                   NVOCC
Password                     TradingPartnersAnd now from this i've to insert into table, say bk_det .
The tag may come in different order, sometimes some additional tags may also come in between,
So i cannot access it sequentially and insert like
Insert into bk_det(file,sndr,rcvr,pswd) values(bk_arr(1).val,bk_arr(2).val....)
The tag name is constant ir for sender id, it will always be SenderID , not something like sndrid or sndid etc..
So if i've to insert to senderid column, then i've to match the tag = SenderID, and take the value at that index in the array.
How best i can do this?
Thanks

I am referring to how you are parsing the XML - as you can extract values from the XML by element name. And as the name is known, it's associated value can be inserted easily.
Basic example:
SQL> with XML_DATA as(
2          select
3                  xmltype(
4 '<?xml version="1.0" encoding="UTF-8" ?>
5 <XML>
6          <File name="S2_240463.201002170044.Z">
7                  <BookingEnvelope>
8                          <SenderID>KNPROD</SenderID>
9                          <ReceiverID>NVOCC</ReceiverID>
10                          <Password>TradingPartners</Password>
11                  </BookingEnvelope>
12          </File>
13 </XML>'         )       as XML_DOM
14          from    dual
15 )
16 select
17          extractValue( xml_dom, '/XML/File/@name' )                      as FILENAME,
18          extractValue( xml_dom, '/XML/File/BookingEnvelope/SenderID' )   as SENDER_ID,
19          extractValue( xml_dom, '/XML/File/BookingEnvelope/ReceiverID' ) as RECEIVER_ID,
20          extractValue( xml_dom, '/XML/File/BookingEnvelope/Password' )   as PASSWORD
21 from       xml_data
22 /
FILENAME                  SENDER_ID RECEIVER_I PASSWORD
S2_240463.201002170044.Z KNPROD     NVOCC      TradingPartners
SQL> Now this approach can be used as follows:
create or replace procedure AddFile( xml varchar2 ) is
begin
        insert into foo_files(
                filename,
                sender_id,
                receiver_id,
                password
        with XML_DATA as(
                select
                        xmltype( xml ) as XML_DOM
                from    dual
        select
                extractValue( xml_dom, '/XML/File/@name' ),
                extractValue( xml_dom, '/XML/File/BookingEnvelope/SenderID' ),
                extractValue( xml_dom, '/XML/File/BookingEnvelope/ReceiverID' ),
                extractValue( xml_dom, '/XML/File/BookingEnvelope/Password' )
        from    xml_data;
end;

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevelThere is no such thing as PL/SQL "+tables+". This is a misnomer and creates the perception that a PL/SQL "table" is somewhat like a SQL table. Nothing can be further from the truth. The correct term is "+collection+" or "+associative array+". Compared to SQL tables, these are very primitive structures, very rigid structures, cannot scale, and can be quite expensive memory wise.
That is not to say do not use an associative array or collection. These are very useful tools.. but only when applied correctly. Like using a collection for a bulk fetch to transfer more rows between the PL and SQL engines and thus decrease context switching.
Unfortunately, quite often we see the row-by-row and slow-by-slow approach - where the developer uses SQL as an I/O only layer, pulls rows into expensive PL engine memory into record structures and arrays, and then process the rows there.
So before looking at working example (even the wrong approach's code will compile and run and work in practice), make sure that you know the fundamentals of correctly using the PL engine and correctly using the SQL engine. And these fundamentals can be summed up into a very basic rule:
Maximize SQL. Minimize PL/SQL+
Get this rule right, and you will have a sound foundation for writing performant and scalable Oracle applications.

JDBC Thin Driver Support for Data Encryption and Integrity

Hello JDev Team,
I am trying to implement JDBC Thin Driver Support for Data Encryption and Integrity.
It works fine with java.sql.Connection and java.util.Properties like in the following code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Properties props = new Properties();
int level = AnoServices.REQUIRED;
props.put("oracle.net.encryption_client", Service.getLevelString(level));
props.put("oracle.net.encryption_types_client", "( RC4_40 )");
props.put("oracle.net.crypto_checksum_client",Service.getLevelString(level));
props.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:main", props);
etc...
But I am developing an application with InfoSwing components and it has a different way to connect to Oracle database using oracle.dacf.dataset.connections.Connection, like this:
sessionInfo1.setAppModuleInfo(new ModuleInfo("bc", "BcModule"));
sessionInfo1.setConnectionInfo(new LocalConnection("JDBCThin"));
sessionInfo1.publishSession();
My question is:
Is there any way to implement DataEncryption and Integrity into this type of connection?
Thanks a lot in advance.
Victor Bykov

Victor,
No, you can't do this from DAC, but I've been discussing it with the developer, and we both think this capability would be useful to have, so I've logged it as an enhancement request.
I do have a question for you. Once you've made the JDBC connection, do you need access to the Connection object afterwards? We're thinking of how the change could be implemented, and one way would be to allow you to pass in a Properties object when creating your own NamedConnection.
Thanks

My husband and I share an email address and if he misses a day checking email on his notebook, he doesn't receive the items that I have sent to Trash on my iPad Mini.
Appreciate suggestions.

Support for RAW Video and Image Sequences

Being a stills photographer who moved into video some years back, I'm very interested in the direction Lightroom is going with regards to video support. I haven't tried it yet but I wondered if LR4 supports Red R3D files? And would it perhaps support other future RAW video formats from the likes of Canon and Sony? It would seem like the perfect application, perhaps intergrating with Premiere in a similar way to RedCine with FCP. Be great to be able to log footage, orginize it into bins and do basic colour correction in LR, edit the project in Premiere and re-touch in After Effects.
Another task LR would seem ideally suited to is combining image sequences into timelapse video. Shooting timelapse as an image sequence on a DSLR is pretty much standard practice these days; and I've used LR to colour correct, crop and scale my sequences (before fitting them together in Quicktime) for years now. It would be fantastic to be able to preview the clip and export the video (as DPX, ProRes or DNxHD) from within Lightroom.
These are obviously fairly long term wishes. In the short term though, the video features are pretty much useless to me without support for exporting ProRes and DNxHD files. With this LR becomes a powerful asset manager that could be used to collect together footage from multiple sources/codecs and transcode it all for editing. As mentioned in a previous thred, XML support would make it even more useful in this context. There is definitly a gap in the market for an application than can handle this kind of task well.
With other manufactures floundering or neglecting their professional user base, Adobe would seem poised to take the video post crown. I wonder if Lightroom could be part of the takeover?

As I understand it Andy, its intention is to remain a photographers program, not a videographers program. The basic video features are available for lightweight management of videos coming from digital cameras, but it's not going too much further than that at this point in time. Of course that may change in the future, but we'll all have to wait and see on that one.

Can anybody explain what is support for ADF Project and to solve the Issues

Hi,
I am new to ADF and i am currently associated to ADF Support Project.
Can anybody explain what is support for ADF Project and to solve the Issues when the ADF Project is in Live.
we are getting the Tickets for the Issues.
Thanks in advance.

I agree with Timo.
It depends on the size of the project, user base, technologies, etc. We use lot of technologies in fusion middleware stack. We get tickets in many areas.
In your case, it could be anything like user training issues (user may not know how to use the some system features), browser issues like blank screen, bugs in code like JBO errors (failed to validate, another user has changed row, failed to lock the record, NullPointerException, IllegalArgumentException etc), business logic issues, page may not render properly, performance issues, partial commit issues, application server issues, authentication issues. If you use web services you might get web services related problems.

Hi,
If the issue persists, I recommend you install Exchange 2007 SP3 RU7 and check the result. Also, ensure that Exchange 2010 SP2 RU1 or later version is installed. Old Exchange version may lead to the CAS-to-CAS proxy incompatibility.
What's more, here are some helpful blogs for your reference.
