Object Data Type support and JDBC2 SQLData interface

Another useful and probably easy to implement feature is to support
persistent-aware classes based on JDBC SQLData interface._
It will let us persist such a member of persistent class to an object
type column._
The interface is very simple and quite limited (no support for arrays
etc) but useful.
The only thing we would need is to maintain jdbc object maps for our
database connections and tell Kodo metadata not to enhance this
particular class member but treat is as a simple type_

In SPROXY you can open your proxy and then view the Activation Log under the GoTo menu. The log will explain better what the problems might be. In my case I needed to activate another data type enhancement first.
Thanks,

Oracle Object Data Type and EJB

Hi, All:
Has anyone implemented a project with Oracle user-defined data type (Object
Data Type) together
with EJB? That is, using ORDBMS (Object Relational Database) together with
EJB. I am thinking to use ORDBMS together with EJB. Any information, samples
and references to this direction is appreciated.
Thanks,

I''ve got a solution! I've had sql in my query
SELECT
ltrim(OPERATIVE_REPORT."orderText",11),
OPERATIVE_REPORT."resolID",
COUNT(OPERATIVE_REPORT."(usrID)order_executionUser")
FROM
OPERATIVE_REPORT
GROUP BY
ltrim(OPERATIVE_REPORT."orderText",11),
OPERATIVE_REPORT."resolID"
where orderText has clob datatype. And the reason is GROUP BY. GROUP BY deny CLOB usage.

Problem to transform Flat file to Data Type Structurated and map to IDOC

Hi all,
I have a file to idoc scenario.
The information is like this:
1#!445#!AI12#!1#!20070214#!DVXXXXR#!201#!31GINHG876#!#!
2#!#!ETC
3#!000000000030008888#!#!3000#!#!10#!#!20070215
4#!dades45#!b#!c#!d#!e#!f#!g
5#!pos5
where 1, 2, ... = key segments for the file adapter and #! are the field separator.
this must go to a Data Type with substructures like this:
(xml)
.1
......2
.3
......4
......5
where 2 is inside 1 and 4-5 inside 3.
The reason of this is we can get unbounded replays of 3/4/5 for one header.
But XI reads the information like if all segments are headers.
.1
.2
.3
.4
.5
So the IDOC is bad created.
Where is the issue? At Message Mapping all substructures are mapped with his default and at TEST option it works fine.
Thanks in advance for your help.
best regards

Dear people,
according to license problems at client, it's impossible to get the convert agent.
so now we come back to try to solve with normal mapping.
the next step is try to convert it using 2 message mappings: dt (flat xml) to dt (structurated) and this one to the idoc.
i suppose it can be done adding program at interface mapping.
I created the no hiereachical Data Type for load the information and it's fine. But i am unable to get the first mapping OK, because XI has problems with unbounded segments.
If you agreed and has time, i copy here the information and his structure.
I receive (#! defines separation and key segment fields are 1,2,3,4,5):

Sysgen : How to read the input port data type, width and rate dynamically in a masked subsystem ?

Hello everybody,
     I am designing a general purpose block in system generator. I pass the user parameters to the block through masking it. Some user parameters can change the block configuration. The input port data type, width and rate can also affect the block configuration.
     The problem is that these values (input port data type, width and rate) are subject to change. So I should read them dynamically, then change the block configuration through programming the "Initialization Commands" field. But unfortunately there is no straight way to read the input port information.
     There are some methods in for example the "Black Box". these are:
input_width = this_block.port('din').width;
input_rate = this_block.port('din').rate;
But these methods are not applicable to a masked subsystem.
I have tried other ways also. You can find them below. None of them worked.
Does anybody know how can I solve this problem?
Other ways I tried:
1)
design_name([],[],[],'compile')
q=get_param(gcb,'PortHandles');
get_param(q.Inport,'CompiledPortDataType')
get_param(q.Inport,'CompiledPortWidth')
get_param(q.Inport,'CompiledPortDimensions')
design_name([],[],[],'term')
2)
ssGetInputPortDataType
3)
ts = Simulink.Block.getSampleTimes([gcb '/Input'])

Today we rely on Simulink to perform parameterization of your designs in two ways:
Parameterizable Subsystems and Blocks : Parameters themselves can be MATLAB expressions that need to be evaluated for which we need the MATLAB interpreter
The very useful Rate and Type propagation or Simulink compilation that allows us to specify types & rates in one location that gets systematically propagated to all.
To truly make the HDL Netlist that is generated from SysGen parameterizable, we would have to implement some of this capability in the HDL netlist itself by:
Using Generics(VHDL) or Parameters(Verilog) - We would have to capture the bit width(type) propagation through levels of hierarchies and finally parameterize the IP itself based on this value
Since IP itself does not have this capability through generics, we would have to package a separate tcl script that updates the IP parameterization appropriately in response to top level parameters(or GUI parameters)
Interpreting MATLAB expressions and translating them into VHDL/Verilog expressions (alternatively tcl expressions of IP). In simulink, mask parameters can be passed from one level to the next. Also parameterization of a block can be composed of Matlab expressions using variables from ancestor masks & the MATLAB interpreter – so we will need to somehow capture that as well.

The data types varchar and varchar are incompatible in the subtract operator

Hi ;
I want to fetch values 6,903,00 format ,my query is ;
SELECT CONVERT(varchar(50), CONVERT(money,SUM(DEBIT)),1) AS DEBIT ,CONVERT(varchar(50), CONVERT(money,SUM(CREDIT)),1),AS
CREDIT CONVERT(varchar(50), CONVERT(money,SUM(DEBIT)),1) - CONVERT(varchar(50), CONVERT(money,SUM(CREDIT)),1) AS BALANCE

it was get error : The data types varchar and varchar are incompatible in the subtract operator.
I want to Show result ;
DEBIT - CREDIT - BALANCE

Thanks in advance

You have to do the subtraction with the MONEY data type (prior to covert-ing).

Pl/sql object data type and "instance of"

Hello!
I have an object datatype A, and two objects, B and C, which are subtypes of A.
Then I have a function taking one parameter of type "A". In runtime, I send an object of type "B" as parameter to this function, and I want to determine if the "A" object is an instance of type "B" or "C". A test similar to "instanceof" in Java. Is there a way to do this in pl/sql?
Thank you.

SUS - Added Data Type Enhancement and Higher level Proxies are not active

Hello,
I've added a field to our current data type enhancement Z_Purchase_Order_Item. Once I regenerate the proxy on the enhancement and activate it the field appears as it should in the high level items that use the enhancement (PurchaseOrderRequest_In). But those proxies have become inactive and when I try to activate them I get this message:
Interface II_BBPX1_SUS_PO was repaired before the Modification Assistant was enabled.
All Modification Assistant functions only apply to future modifications, not to those already
undertaken. This means:
-The modification overview only displays future modifications.
-When resetting to the standard, the system will reset all objects to their current version, since
the actual standard can no longer be identified by the Modification Assistant.
-Support for adjustment after an upgrade will only be available for future modifications.
Modifications that already exist must be re-made manually using version management.
The next message says:
Object can only be created in SAP package.
Then the status bar shows "Proxy Activated". But when I close and reopen the proxy I see that it is once again inactive.
Does any know what I need to do to activate this proxy?
Thanks,
Matt

Using CLOB data type - Pros and Cons

Dear Gurus,
We are designing a database that will be receiving comments from external data source. These comments are stored as CLOB in the external database. We found that only 1% of incoming data will be larger than 4000 characters and are now evaluating the Pros and Cons of storing only 4000 characters of incoming comments in VARCHAR2 data type or using CLOB data type.
Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;
- bind variables cannot be assigned CLOB value;
- dynamic SQL cannot use CLOBs;
- temp tables don't work very well with CLOBs;
- fuzzy logic search on CLOBs is ineffective;
- not all ODBC drivers support Oracle CLOBs
- UNION, MINUS, INTERSECT don't work with CLOBs
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?

Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;They can be stored inline too. Depends on requirements.
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;Toad is a developer tool so that shouldn't matter. What should matter is how you display the data to end users etc. but that will depend on the interface. Some can handle CLOBs and others not. Again, it depends on the requirements.
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;Why would they struggle? 18,000 characters is only around 18k in file size, that's not that big to a web page.
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;Who's caching them in memory? What are you planning on doing with these CLOBs? There's no real reason they should impact performance any more than anything else, but it depends on your requirements as to how you plan to use them.
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;You can manipulate CLOBs in SQL too, using the DBMS_LOB package.
- bind variables cannot be assigned CLOB value;Are you sure?
- dynamic SQL cannot use CLOBs;Yes it can. 11g supports CLOBs for EXECUTE IMMEDIATE statements and pre 11g you can use the DBMS_SQL package with CLOB's split into a VARCHAR2S structure.
- temp tables don't work very well with CLOBs;What do you mean "don't work well"?
- fuzzy logic search on CLOBs is ineffective;Seems like you're pulling information from various sources without context. Again, it depends on your requirements as to how you are going to use the CLOB's
- not all ODBC drivers support Oracle CLOBs not all, but there are some. Again, it depends what you want to achieve.
- UNION, MINUS, INTERSECT don't work with CLOBsTrue.
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?You may have more hassle if you "need" to accept more than 4000 characters and you are splitting it into seperate columns or rows, when a CLOB would do it easily.
It seems as though you are trying to find all the negative aspects of CLOBs and ignoring all the positive aspects, and also ignoring the negative aspects of not using CLOB's.
Without context you're assumptions are just that, assumptions, so nobody can tell you if it will be right or wrong to use them. CLOB's do have their uses, just as XMLTYPE's have their uses etc. If you're using them for the right reasons then great, but if you're ignoring them for the wrong reasons then you'll suffer.

Discoverer 4i - Time Series Data type support

Does Discoverer 4i support time-series data type i.e. the ability to store an entire string of
numbers representing for example daily or weekly data points?
Thanks & Regards,
Deepti

Hi O G-M,
Each model must contain one numeric or date column that is used as the case series, which defines the time slices that the model will use. The data type for the key time column can be either a datetime data type or a numeric data type. However, the column must
contain continuous values, and the values must be unique for each series. The case series for a time series model cannot be stored in two columns, such as a Year column and a Month column. For more information about it, please see:

Data types supported in weblogic web service

I have used byte[] (base64) array to pass binary data using weblogic in a web service, since byte[] is a java datatype that is supported, is there a definite guideline available that byte [][] ( multi-dimensional array} is not supported in weblogic 8.1? (I have tried and failed with byte [][])
Thanks

Hi gchirrav ,
Multi-Dimentional array support not listed in supported Data Types in weblogic 8.1.
Go through the following link, you will find supported data types.

Data type Replication and ODBC

I want to convert table that has column with LONG datatype to
supported datatype by replication. Currently the LONG column
contains more than 4,000 bytes so I can't convert to Varchar(2).
If I convert to CLOB then the application that we are using is
connecting through ODBC drivers and CLOB is not supported by
ODBC.
Is any one run into this situation? What is recommended or
practical solutions for this problem?
Thanks.

Thx,
I used data type java.sql.Timezone and it works fine ;) This data type parse Date to format yyyy-MM-dd hh:mm:ss, so basically does not matter if I use string or this type :) but this is better ;)
Problem is in timezone ! :( In data type java.sql.Timezone is not possible set timezone! :(

Tg4msql - Blob Data Type Support(Oracle 8i - sql server 2000)

hi,
We are trying to replicate the data from oracle 8i to sql server 2000 through tg4msql.if we want to replicate the data thet contains the blob field , we are getting invalid expression in the procedure marked with error line.
the procedure i am using is as follows
CREATE OR REPLACE PROCEDURE INSERT_SQL
AS
BEGIN
FOR VAL_CURSOR IN
--Get the Data from the table with status 0
SELECT rs_report_rowid FROM BIJU.rs_report where rs_report_status = 0
LOOP
for new_cursor in
--get the details of the record with the row id
select id ,name,DOB from biju.sample where rowid = val_cursor.rs_report_rowid
LOOP
---insert the data from oracle to sql where the oracle data type contains blob(here photo field data type is blob).
Error Line: insert into [email protected](id,name,photo) values(new_cursor.id,new_cursor.NAME,new_cursor.DOB);
END LOOP;
END LOOP;
COMMIT;
END;
i want to know that tg4msql won't support the blob data type on the oracle end?we configured blob eqivalent in sql server as binary.Any help or suggestion regarding this are welcome..
regards
Srini

Srini,
Support for LOB was added in v9.2. It is not supported in 8i.

Change Date Type Description and Re Arrange

Dear Expert,
I would like to change description of each date type in block date and arrange date rows as new sequence in IC Web Client, I try to do it on t-code BSP_DLC_SDESIG_DL but I cannot, the transaction allow to adjust only field STRUCT.APPT_TYPE_DESCR description , I would like to change each date value description in this structure and arrange them. Have anyone used to do this? Please suggest me.
Best Regards,
Krin
Edited by: Krin Thongkam on Aug 3, 2010 11:22 AM

Hi,
If you mean the Dates assignment block; this is populated by the date profile assigned to your transaction type.
Go to SPRO --> CRM --> Transactions --> Basic Settings. You can find which date profile is used for your transaction type in the detailed view.
Then go to SPRO --> CRM --> Basic Functions --> Date Management --> Define Date Profile. Here you can check which date types are used in your profile. You can rename these using SPRO --> CRM --> Basic Functions --> Date Management --> Define Date Types, Duration Types and Date Rules. I think the sequence of the dates is determined alphabetically on date type.

Data type support 9i Release 2

Does oracle 9i relase 2 support the float datatype for replication .

As a matter of fact oracle 9i has two types of api for external tables one is oracle_loader and the other is oracle_internal which in 10g become oracle_datapump.
What my question is how can I use the other type in case of external table as we are doing in 10g? Do I need to run any script to enable this feature or is there any privillege issue?
I've given the read, write privillege to the user and the oracle user has read/write permission in os level on the location of the directory.
