I am querying a view in sqlserver 2000 via an odbc database link.
When I query a 26 character wide column in the view in sql developer, it will only return up to 13 characters of the data.
When I query the exact same view in the exact same sql server database from the extact same oracle database using the exact same odbc database link using sql navigator, I get the full 26 characters worth of data.
It also works just fine from the sql command line tool from 10g express.
Apparently, sql developer is confused about how to handle multi-byte data. If you ask it the length of the data in the column, it will tell you 26, but it will only show you 13.
I have found a VERY PAINFUL work around, to do a cast(column_name as varchar2(26) when I query it. But I've got hundreds of views and queries...

In all other respects, the settings I have appear to be working correctly.
I can enter multi-byte characters into the sql worksheet to create a package, save it, and re-open the package with the multi-byte characters still visible.
I'm using a fallback directory for my jdk with the correct font installed, so I can see and edit multi-byte data in the data grids.
In this case, I noticed the problem on a column that only contains the standard ascii letters and digits.
Environment->Encoding = UTF-16
All the fonts are set to a font that properly displays western and ge'ez characters. The font has been in use for years, and is working correctly in all other circumstances.
The Database->NLS Parameters tab under sql developer preferences shows:
language: American
territory : American
sort: binary
comp: binary
length: char (I've also tried byte)
If there are other settings that you think might be relevant, please let me know.
I've done some more testing. I created an oracle table with a single column and did an insert into ... select from statement across the database link. The correct, full-length data appeared in the oracle table.
So, it's not a matter of whether the data is being returned or not, it is. It is simply not being displayed correctly. It appears that sql developer is making some unwarranted decisions about the datatable across the database link when it decides to display the data, because sql plus and sql navigator have no such issues.
This is really a very serious problem, because if I cannot trust the data the tool shows me, I cannot trust the tool.
It is also an invitation to make an error based upon the erroneous data display.

Display selected language in multi-language environment

Hi there
I have 3 keyboards defined in settings>General>Keyboard EN, FR, DE
Swapping from one to the other shows me shortly on the spacebar the language I've chosen. Also the "return" key is renamed. Bad thing is that DE and EN both use the term "Return"
Has somebody an idea how I could display the active language as icon, or as text on the spacebar (like iphone 3.1), or whatever solution exist
Thanks for your help

To my knowledge there is no way to change anything like this on the iPad. If you hold down the Globe button you can see a list and tell what keyboard is active. That is all there is at present.

OBIEE11g - Report Multi Currency Display (Static Data)

Hi All,
I have a requirement where i need to display amount data in multi currency format in OBIEE 11g like LCY and OCY format.User have to select the currency type like USD,YEN,EURO and resulting amount data in report should display in that currency format.
Pls suggest me is it required to do ETL Changes i.e we need to load data in Database in multi currency format
can we do this at Report level i.e can convert the amount in required currency format.
Note: Spot rate is currency data it's loading by monthly its a static data.
please refer my expected output screen short:
http://imageshare.web.id/images/0dnlgxlvmhl7u5tdbac1.jpg
(currently we are displaying one currency now we need to show multicurrency)
Just FYI...
joins:
"GPC_DataMart"."GPC_DataMart"."dbo"."MX_SPOT"."OCY" =
"GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."ORIG_CURRNBR"
AND
"GPC_DataMart"."GPC_DataMart"."dbo"."MX_SPOT"."PPN_DT" = "GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."Business_Date"
here ocy & ORIG_CURRNBR is the foreign currency (i.e: USD,YEN,EURO etc)
Calculation part:
CASE WHEN "GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."Product_Type" IN ('Bond', 'Bonds', 'Callable Bonds')
THEN "GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."Nominal_AMT" * "GPC_DataMart"."GPC_DataMart"."dbo"."MX_SPOT"."NON_DISC_SPOT"
WHEN "GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."Product_Type" ='Equities' THEN
("GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."MKT_VALUE" - "GPC_DataMart"."GPC_DataMart"."dbo"."IW_POSITION"."CAPITAL_GAIN" ) * "GPC_DataMart"."GPC_DataMart"."dbo"."MX_SPOT"."NON_DISC_SPOT"
END
in the above calc amount * spot_rate
I already refer the below one but it wont suite for my case:

BI Bean that displays the data in tabular layout (multi-row)

Hi,
I know there isn't a graphic type in BI Beans that can display data in multi-row tabular layout as one graphic object. Oracle Forms can actually display this layout but they want to display everything in one page without scrollbars (without the need to scroll for the other records that isn't displayed yet in the screen). Is this at all possible in Oracle Forms using BI Beans? Are there other possible approaches aside from BI Beans?
Thanks in advance.

Hello Vikas,
>> How does one go about troubleshooting & fixing this sort of thing?
By given us a bit more information :)
• Is it a manual Tabular Form (using the ITEM API) or a wizard created one?
• Are the Insert/Update operations work correctly? If not, what is the type of your PK column(s)?
• If the problem is limited to the Delete operation, maybe the problem lies with the checkbox column. Are you sure that on page it is rendered as the f01 column?
• As triggers are involved, can you save the PK that the trigger sees? Is it the expected value?
• Are there any other processes that are fired before the DML process? If so, maybe the problem is with them. You can temporarily disable them and see if it change anything.
>> Tabular forms are the most frustrating, opaque component in Apex, wish they were easier to troubleshoot
Yes, I agree. However, I believe that 4.1 made some serious advancement where Tabular Form is concerned. Having simplified Tabular Form related Validations and Process should make things easier, and as a result, prone to less errors. Still, the main problem is that the type of error you are talking about is usually the result of metadata problems and these are indeed very hard to track.

Report to display (actuals data from one cube and plan from another)

Hi Gurus,
         I have a requirement in reporting to display actual data from one cube and plan data from a different one.
        The example below might give a clear picture of the requirement.
rows has key figures and columns = months
Jan | Feb | Mar | Apr | May | Jun ...   ....
GrossSales
Net Sales
Now if I run the report for Current month (Apr), then for the months of (Jan, Feb and Mar) i need to get the data from CUBE1   and for the remaining months (Apr thru Dec) from CUBE2.
Similarly when i run the report next month(may),
then (data for Jan, Feb, Mar, Apr from CUBE1)
and ( May thru Dec from CUBE2)
Any suggestions.
Thanks in Advance
Kumar

Hi Henry,
     We alreadey have a multi provider which includes
FinDat Cube(CUBE1) for actuals and Comm.Goals cube (CUBE2) for plan.
So you suggest that we have two versions of key figure for actual and plan.
ie. each KF will have two versions.
actuals = (version 10, FiscPer<curr.mnth, key figure, acutals cube)
Plan = (version 20, FiscPer>=curr.mnth, key figure, comm.goals cube)
eg:
Jan | Feb | Mar | Apr | May | Jun ...
GrossSales(Act)
GrossSlaes(Plan)
Net Sales(Acutal)
Net Sales(Plan)
Correct me if I am wrong.
the report has a lot of key figures, having two versions for each kf will be confusing.
the user would like to see
Jan.....| ...Feb |..Mar |..Apr.....| May |
GrossSales   Act Value|Act.V |Act.V| PlanVal|PlanVal|
Net Sales
where Act.Value is from CUBE1
         Plan Value is from CUBE2
Thanks

Problem to display japanese/multi-byte character on weblogic server 9.1

Hi experts
We are running weblogic 9.1 on linux box [REHL v4] and trying to display Japanese characters embedded in some of html files, but Japanese characters are converted into a question mark [?]. The html files that contain Japanese characters are stored properly in the file system and retained the Japanese characters as they should be.
I changed character setting in the html header to shift_jis, but no luck. Then I added the encoding scheme for shift_jis in jsp_description and charset-parameter section in weblogic.xml but also no luck.
I am wondering how I can properly display multi-byte characters/Japanese on weblogic server without setting up internationalization tools.
I will appreciate for your advice.
Thanks,
yasushi

Can Iphoto display the date and time of a pic on the pic?

I know I can get info and see a pics info, but can Iphoto display the date and time of a pic on the pic itself?

Use the Photos->Batch Change menu option to set the Title to Date and Time. That will give you what you want under each thumbnail.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
NOTE: iPhoto 8's new option in the library rebuild pane, "Rebuild the iPhoto Library Database from automatic backup" may make this tip obsolete. We'll know when users have occasion to use it and see if that's the case.

Group data with multi tables in report.rdlc

I have a report.rdlc which contains 8 tables and every table reads from different dataset which also reads from different procedure, these tables finally view data for one employee, and this was working correctly. Now I need to view the same report but
for multi employees, I don't know how to make one group(employee number) for the 8 tables although they have different datasets and procedures
this is a Pressing problem
please help me

Hi nermo,
According to your description, you want to display 8 tables in detail rows group on employee number. So it will have 8 tables for each employee. Right?
In this scenario, we can create a dataset whick only return the employee number and put the employee number into a table. Put the 8 tables into 8 separated reports, then add these reports as subreports into detail row. It will display these data even they
are from 8 different dataset. If you want to filter the records in those tables based on the employee number. You need to have the Employee parameter in both main report and subreports and pass the parameter to run subreports. We have tested in this scenario
in our local environment. Here are screenshots for your reference:

Display of data based on priority

Hi All,
I have a requirement of displaying data based on the priority of numbers.
Example: There are 3 Part Numbers- 342, 310, 317.
I want to store this data in Lookup table(Multi).
Is it possible to display the data based on the number like 310, 317 & then 342.
Is there any other option to do this?
Regards,
Pramod

Is it priority or is it sorting of records?
If this is sorting then you can do it in data manager, in your lookup flat just click on field name (column name) data manager automatically sort the record or right click on column name>sort>ascending/descending.
If this is priority case then please elaborate more.
Howevere, In multivalued field when you will take say 310 and 317 in main table record and do search on it in both the cases 310 and 317, DM will display same field means this record will be common in 310 and 317.
if your question is concerned to different tings, please explain.

Strange scenario,Oracle can not display the data in mysql correctly

I use Heterogeneous Service+ODBC to achieve "oracle access mysql"(any other method?),and now i find Oracle can not display the data in mysql correctly:
-------mysql------------
mysql> create table tst(id int,name varchar(10));
Query OK, 0 rows affected (0.00 sec)
mysql> insert into tst values(1,'a');
Query OK, 1 row affected (0.00 sec)
mysql> select * from tst;
------------+
| id | name |
------------+
| 1 | a |
------------+
1 row in set (0.00 sec)
mysql> show create table tst\G
*************************** 1. row ***************************
Table: tst
Create Table: CREATE TABLE `tst` (
`id` int(11) DEFAULT NULL,
`name` varchar(10) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8
1 row in set (0.00 sec)
-------------oracle ------------------
SQL> select count(*) from "tst"@mysql;
COUNT(*)
49
SQL> select * from "tst"@mysql;
id
1
SQL> desc "tst"@mysql;
Name Null? Type
id NUMBER(10)

You can make the following query on the result page:
"select * from the_table where movietitle = ? and cinema = ?"
then you set movietitle and cinema to those which the user selected. If the resultset contains more than 0 rows, that means the movie is available.
Below is the sample code, it assumes you have a connection to the database:
PreparedStatement stat = myConnection.prepareStatement("select * from the_table where movietitle = ? and cinema = ?");
stat.setString(1, usersMovieTitleSelection);
stat.setString(2, usersCinemaSelection);
ResultSet res = stat.executeQuery();
if (res.next()) {
out.print("The movie is available");
} else {
out.print("The movie is not available");
}Now just add that to your JSP page. Enjoy ! =)

Not displaying the data in the ALV Microsoft Excel (Ctrl+Shift+F7)..

Hi,
Check whether the tool bar export is disabled in the alv.
check in the alv->set_table_for_first_display FM the toolbar exclude export list.
If that is ok, then try download manually by providing abutton and clicking it. You can download data manually in this way.

DataGrid does not display XML data

Hello, and thanks for reading this...
I am having a problem displaying XMLList data in a DataGrid.
The data is coming from a Tree control, which is receiving it
from a database using HTTPService.
The data is a list of "Job Orders" from a MySQL database,
being formatted as XML by a PHP page.
If it would be helpful to see the actual XML, a sample is
here:
http://www.anaheimwib.com/_login/get_all_orders_test2.php
All is going well until I get to the DataGrid, which doesn't
display the data, although I know it is there as I can see it in
debug mode. I've checked the dataField property of the appropriate
DataGrid column, and it appears correct.
Following is a summary of the relevant code.
...An HTTPService named "get_all_job_orders" retrieves
records from a MySQL database via PHP...
...Results are formatted as E4X:
HTTPService resultFormat="e4x"
...An XMLListCollection's source property is set to the
returned E4X XML results:
...The "order" node is what is being used as the top-level of
the XML data.
<mx:XMLListCollection id="jobOrdersReviewXMLList"
source="{get_all_job_orders.lastResult.order}"/>
...The "jobOrdersReviewXMLList" collection is assigned to be
the dataProvider property of a Tree list, using the @name syntax to
display the nodes correctly, and a change event function is defined
to add the records to a DataGrid on a separate Component for
viewing the XML records:
<mx:Tree dataProvider="{jobOrdersReviewXMLList}"
labelField="@name"
change="jobPosForm.addTreePositionsToDG(event)"/>
...Here is the relevant "jobPosForm" code (the Job Positions
Form, a separate Component based on a Form) :
...A variable is declared:
[Bindable]
public var positionsArray:XMLList;
...The variable is initialized on CreationComplete event of
the Form:
positionsArray = new XMLList;
...The Tree's change event function is defined within the
"jobPosForm" Component.
...Clicking on a Tree node fires the Change event.
...This passes an event object to the function.
...This event object contains the XML from the selected Tree
node.
...The Tree node's XML data is passed into the positionsArray
XMLList.
...This array is the dataProvider for the DataGrid, as you
will see in the following block.
public function addTreePositionsToDG(event:Event):void{
this.positionsArray = selectedNode.positions.position;
...A datagrid has its dataProvider is bound to
positionsArray.
...(I will only show one column defined here for brevity.)
...This column has its dataField property set to "POS_TITLE",
a field in the returned XML record:
<mx:DataGrid width="100%" variableRowHeight="true"
height="75%" id="dgPositions"
dataProvider="{positionsArray}" editable="false">
<mx:columns>
<mx:DataGridColumn width="25" headerText="Position Title"
dataField="POS_TITLE"/>
</mx:columns>
</mx:DataGrid>
In debug mode, I can examine the datagrid's dataProvider
property, and see that the correct XML data from the Tree control
is present. However, The datagrid does not display the data in any
of its 6 columns.
Does anyone have any advice?
Thanks for your time.

Hello again,
I came up with a method of populating the DataGrid from the
selected Item of a Tree Control which displays complex XML data and
XML attributes. After the user clicks on a Tree branch, I call this
function:
public function addTreePositionsToDG(event:Event):void{
//Retrieve all "position" nodes from tree.
//Loop thru each Position.
//Add Position data to the positionsArray Array Collection.
//The DataGrid dataprovider is bound to this array, and will
be updated.
positionsArray = new ArrayCollection();
var selectedNode:Object=event.target.selectedItem;//Contains
entire branch.
for each (var position:XML in
selectedNode.positions.position){
var posArray:Array = new Array();
posArray.PK_POSITIONID = position.@PK_POSITIONID;
posArray.FK_ORDERID = position.@FK_ORDERID;
posArray.POS_TITLE = position.@POS_TITLE;
posArray.NUM_YOUTH = position.@NUM_YOUTH;
posArray.AGE_1617 = position.@AGE_1617;
posArray.AGE_1821 = position.@AGE_1821;
posArray.HOURS_WK = position.@HOURS_WK;
posArray.WAGE_RANGE_FROM = position.@WAGE_RANGE_FROM;
posArray.WAGE_RANGE_TO = position.@WAGE_RANGE_TO;
posArray.JOB_DESCR = position.@JOB_DESCR;
posArray.DES_SKILLS = position.@DES_SKILLS;
positionsArray.addItem(posArray);
So, I just had to manually go through the selected Tree node,
copy each XML attribute into a simple Array, then ADD this Array to
an ArrayCollection being used as the DataProvider for the DataGrid.
It's not elegant, but it works and I don't have to use a Label
Function, which was getting way too complicated. I still think that
Flex should have an easier way of doing this. There probably is an
easier way, but the Flex documentation doesn't provide an easy path
to it.
I want to thank you, Tracy, for the all the help. I checked
out the examples you have at www.cflex.net and they are very
helpful. I bookmarked the site and will be using it as a resource
from now on.
