Problem with slash character in CONTAINS queries

Hi there,
i've got a problem with a CONTAINS query using Oracle Text.
The following query works fine:
select col1 from my_table_text where contains(text,'%02%')>0;
When i'm trying the query
select col1 from my_table_text where contains(text,'%02/%')>0;
the following error occurs:
ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: Oracle Text error:
DRG-50937: query too complex
I didn't find anywhere that the slash has a special meaning (escape character or something else). This occurs only when the slash character is positioned immediately after or before the % operator. The search string '%0/2%' works.
Oracle version: 9.2.0.1.0
OS: Solaris 8 SPARC
Maybe someone can help me.
Thanks in advance,
Chris

Hi Chris,
I think you want to search for all words having '02/'.
Am I right? In that case try using '02//'
Yes. '/' means escape character. So when it finds '/%' it tries to escape '%'.
Hope this helps.

URGENT Problem with Greek Character from an Oracle database

Hello, I am having a serious and urgent problem with the character settings of an oracle database (8.1.7). The database is sitting in a solaris unix server and when we run the env command we have the following in the NLS_LANG parameter: AMERICAN_AMERICA.WE8ISO8859P1 (I do not know if this is helpful). When I retrieve data from oracle database (through a VB.NET 2005 program)to a dataset I use a special font in order to see the greek characters (HELLASARIAL). But when I am trying to save these data to a TXT file the greek characters are like Chinese to us. I tried several encodings (System.Text.Encoding.GetEncoding(869)) but without success. Can someone tell me how to convert the oracle greek characters during the selection or during the saving to the TXT file?
Please respond as fast as you can.
Thanks in advance

Here is the answer of the microsoft:
I have the information that you have a VB.Net 2005 application connected to an Oracle database 8.1.7.4 hosted on a UNIX server.
This database has the CharacterSet WE8ISO8859P1.
When retrieving Greek characters from this database in the application, you cannot see them.
Could you please send me a screenshot of these characters in the .Net application?
Are they displayed as gibberish, or as inverted questions marks (?)?
I already had similar cases with Hebrew characters hosted on an Oracle database.
These characters were displayed as questions marks on the client side.
This is due to the fact that System.Data.OracleClient is using the Server CharacterSet to display the characters.
If your Greek characters are not stored in the WE8ISO8859P1 characterset, then they won’t display correctly on the client-side.
This is different from OLEDB where you could interact on client side by modifying the NLS_LANG parameter in the registry HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0.
The client NLS_LANG and the server CharacterSet had to match in order to correctly display the data, and avoid SQL*NET conversion.
So there are two solutions to your case:
- The first one is to create a new database using the P8 characterset. The Oracle .Net managed provider will so be able to use it and display the characters correctly.
- The second one is to use the OLEDB.Net managed provider, and then use OLEDB for Oracle provider. OLEDB will take care of the client NLS_LANG registry parameter.
Would it be possible to test your application against an Oracle database with WE8ISO8859P8 characterset?
Would it be possible to test it with the OLEDB .Net managed provider, and after checking the NLS_LANG client registry parameter?

I'm having problems with FlashPlayerPlugin and plugin-container. They keep starting up and bogging down the system. This has been a recent occurrance. I've made sure that I have the latest version. I notice the problem when I am opening some applicatio, and it freezes. If I go to Task Manager, I can see the two Adobe apps sucking up CPU cycles. If I end the processes, then the other apps continue. Today, I uninstalled FlashPlayerPluginqand plugin-container. All day since I have had no freezing of an app. What should I do to correct the problem?

Here's an explanation of what those processes are.
Inside Flash Player Protected Mode for Firefox
I'm curious about what you did to uninstall just those.

I keep getting a message about a problem with the plug in container for firefox. what does it mean?

I am getting a pop up box saying that there is a problem with the plug in container for firefox. It keeps saying do I want windows to find a fix for it and close it or do I just want to close the program. What is this plug in container for firefox and why am I constantly getting this message? It has been happening for the past month or two.

It means either you have a faulty/out of date plugin, or your firewall/antivirus is causing problems with Firefox.
Make sure you update all your plugins and disable unwanted ones.
https://www.mozilla.org/en-US/plugincheck/
https://support.mozilla.org/en-US/kb/disable-or-remove-add-ons
Also, make sure your firewall/antivirus is not blocking plugincontainer.exe from the Firefox folder in your computer. How you make sure that's not the case will depend on your firewall/antivirus.

Problem with the result of multiple queries in Web Intelligence (BO XI R2)

We have a problem with Web Intelligence reports. Behavior of the results is like if we selected the function Count in Designer the properties indicators. Same queries separated one for one report give correct results and together 7 queries in one report give correct results only for the first query and for others (6 others) same results for each date (if report is monthly) or the same result for each hour (if the result is daily) for all Queues tested (other which were not tested have result 0). Even the function Sum inserted into the report structure behaves weird u2013 we have the same result as in the filed (it is a copy of that result, not a sum). We tested queries together in SQL Developer and they give correct results, while in BO big query which contains script from Query 3, Query 2 and Query 1 cannot be completely executed (it executes without end).
We use Business Objects XI R2 SP3.
Thanks in advance.

Hi Peter,
I guess it is the problem due to the merged dimension and different granurality level in the BO queries. From the document properties uncheck the option of auto-merge common dimension objects or manually unmerge all the common dimensions
than give it a try.
I guess this would solve your problem. If not can you provide more query details like what objects you have used in the query.

Adobe forms - problem with the character "9"

I have the problem with printing Adobe forms that were introduced with Russian country version.
Funny enough I have no problems with russian characters. They all print all right.
We have however the problem with character "9". On the preview of the pdf it looks ok. When I print it from PDF preview it prints ok. But when I process it for sap to the HP output device (device type HPLJ4) "9" gets replaced with "<".
Has anyone experienced this problem?

ok, you're right. But, my problem is a little bit different :
I would like to replace the "\n" character (new line) by the 2 characters "\n".
I test this source code :
String tmp = "First line\nSecond line";
tmp.replaceAll("\n", "\u005C\u005Cn");
System.out.println(tmp);
tmp.replaceAll("\n", "\\n");
System.out.println(tmp);
tmp.replaceAll("\n", "\\\\n");
System.out.println(tmp);
The 3 results are the same :
First line
Second line
I never have "First line\nSecond line".
Best regards.
K96
PS : The objective is to write the string in a SQL request.

Problem with a character in an external table

I have Unix Sun OS 5.8
I received 1 file with data. The problem is that this file has a character ' ' in the end file then the charge has an error. The character in the end file is in hexadecimal: 0A, 1A.
Then I have an External table and I put the the clause LOAD WHEN (COMARC != ' ') but when I edit the external table I see LOAD WHEN (COMARC != '.').
And the last record with the ' ' character doesnât filter.
Note: the character isn't a space ' '. It is the hexadecimal: 0A, 1A
What I have to put in the LOAD WHEN (COMARC != '??????????') to filter this character?

I put LOAD WHEN (COMARC != x'0A1A') but I receive the error:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-00554: error encountered while parsing access parameters
KUP-01005: syntax error: found "single-quoted-string": expecting one of: "and, not, or, )"
KUP-01007: at line 3 column 26
ORA-06512: at "SYS.ORACLE_LOADER", line 14
ORA-06512: at line 1
If I put:
LOAD WHEN (COMARC != ' ') for example I don't received any error!
What happens?
Thanks!

ABAP Objects: Problems with controls in splitter container

Hi community,
I have problems with the second control in a splitter container.
In the left container I build up a <u>list tree</u>.
On double click on a node a <u>column tree</u> in the right container is created.
This is working fine.
But if I double click on another node in the left container the right tree remains unchanged.
What do I have to do to update/refresh the tree in the right splitter container.
Thanks in advance.
Regards
Ferdi

Thanks for your reply Thomas and Serdar,
I now destroy the right container and the right tree control if it exists after the event 'double_click' on a node in the left tree.
The result is now that the container is created (I can see it on screen) but no tree is shown.
If I just destroy the tree control but not the container the tree from the first double click on the left tree is shown.
In the debugger I see that the list tree instance is linked to the caontainer (after first and second creation of tree control)
Maybe you can see in the coding below what's wrong or missing.
Coding after EVENT DOUBLE_CLICK in left Tree: <pre>
destroy old tree instance and container
if not g_container_2 is initial.
    call method g_container_2->free.
    clear: g_container_2, g_tree_2.
endif.
create right container
call method g_splitter->get_container
            exporting row      = 1
                      column   = 2
            receiving container = g_container_2.
setup the hierarchy header
hierarchy_header-heading = 'Hierarchy Header'.
hierarchy_header-width = 37.
create a column tree model instance
create object g_tree_2
    exporting
      node_selection_mode = cl_column_tree_model=>node_sel_mode_single
      item_selection = 'X'
      hierarchy_column_name = 'C1'
      hierarchy_header = hierarchy_header.
create tree control
call method g_tree_2->create_tree_control
    exporting
      parent = g_container_2.
perform add_columns.
perform define_events.
set registered events
call method g_tree_2->set_registered_events
    exporting
      events = events.
perform get_data.
perform add_nodes_2.
expand the root node
call method g_tree_2->expand_node
    exporting
      node_key = 'Root'
      level_count = 3.
</pre>

Instant Messenger has problem with disorder character

Hi all,
We have problem with some disorder character in IM.
Actually it happens with the name of contact. We use Chinese version, all are ok except the name of the user, it's strange. We also find the codeset is UTF-8, but only name perform a disorder problem.
Any idea? Thank u in advance.

Update:
Chinese words can be typed and display properly except the name of the speaker, just like MSN, in the content we can see:
$&%& : hello, <some chinese words>
@#$^&: hello, ...
This is the problem.

Problem with JavaFX 8 Self-contained Application !

Hello everybody,
I generate a JavaFX 8 Self-Contained Application for Windows (.msi).
Eclipse 4.3.1 (Kepler)
JDK 8 B116 (EA - i don't use the lasts beta versions (B117 and B118) because there is a bug during installation for Windows XP)
Scene builder 2.0 (EA)
When i install this application (exec .msi) on my PC (Windows XP SP3 - JDK 7 and 8 installed), no problem.
So i install this application on 2 others PC (PC without JDK 8 installed).
The first PC on Windows XP SP3 (JDK 5 and 6 installed) : display problem - the font is very big as if I had made a zoom on the contents of the window !
The second PC on Windows 7 PRO (JDK 7 installed) - when in launch the application by the system menu, i have two strange problems
1/ when i move my mouse on the content of the window, this content becomes black !
2/ it's necessary to resize the window (full screen) and to come back to the original size to obtain a correct display !
I don't know where is the problem(s) ?
is it linked to JDK 8 (BETA version) embedded ?
If you have a idea do not hesitate !
Thanks you in advance

I only use external FW HDDs for my video work; my Capture Scratch files are on external drives and I export finished movies to external drives. My project files are on my system drive, this is the best way to work, I have never had any problems I could associate with this configuration
I am assuming you've gone thru your project, your timeline and everything is kosher. Is everything fully rendered? Have you mixed down your audio? Have you tried exporting just the last 30 seconds of one of the projects to see if you can replicate the problem?

Problem with chinese character for dot matrix epson LQ-1600K III

Hi All,
I really runs out of idea about my problem now. The problem is about Print Chinese character to dot matrix printer (Epson LQ-1600K III). I tried to so many device type to solve this issue, looks like the only device type can be use are CNSAPWIN and CNEPSON with CNSONG font type. The others if I print to the printer, the chinese character became # (although in the print preview it`s okay and display correctly).
Here is the bottleneck if I use CNEPSON:
- if I have 2 window at the left and right position, if the left window has chinese character, the right window automatically shift right about 1.5 CM, which is damn weird!!! Can somebody help me
- I tried so many ways to adjust the line size for my detail window (to cater positioning at pre-printed boxes), but looks the font size always become 10pt and line size cannot be adjustable (based on smartstyle).BUT if I used device type epescp2, it can be done!
Here is the bottleneck if I use CNSAPWIN:
- I need to create format type in windows and SAP (SPAD). and every PC that use this printer, must define the Paper size ( China Special paper size 12inch)
- I also think this is not a good idea because as I far as I know this is not the correct way..
Therefore, if somebody has experience about printer chinese character to dot matrix for Smartform and sapscript..please kindly help me give some advice.
Do I use the wrong device type?
Thanks in advance!
Regards,
Willy

Hi friends , we are using the same model ....
Are you using the chinese version operation system ? because we can print the chinese charaters without problem in LQ 1600KIII .....
We are using CNSAPWIN device type + Frondend printing access method ....

Problem with special Character & in Proxy

Hi,
We have a File --> XI --> R/3 Scenario. In this scenario, from XI we are passing the data to R/3 by calling the Proxy. When the data in the file has special character like & (for example <Companyname>Dave&Busters</Companyname>), it is failing in R/3. But if I replace "&" with "&" in the file it works fine. Is there any solution to this problem without writting custom code in XI to replace & with &.
Thanks
Sudheer

>But if I replace "&" with "&" in
> the file it works fine. Is there any solution to this
> problem without writting custom code in XI to replace

No. If the sender of the message provides an XML format with an unescaped &, then the XML is not valid and therefore cannot be processed.
All adapters (IDOC, RFC, File with content conversion) perform the escaping and deescaping.

Problem with Japanese character Codes

I have been working for a company which got a product to support the sms activities. We are developing a new feature which supports Japanese language as of now along with english. We developed a new character set called PDC which is a combination of the following Japanese character sets JIS + SHIFT- JIS+ KATAKANA + ASCII.
I am using Java API Charsets.jar to convert the bytes using the respective character sets to a STRING and presenting the converted STRING on a JSP.
The Problem is I am able to see the Jap Chars which belong to JIS + ASCII but not for KATAKANA and SHIFT-JIS.
I am using the below page tag in JSP.
<%@ page contentType="text/html; charset = JIS " %>
I couldn't find any other tag specifically which supports all the character sets. Could some one please help me?
Pradeep.

Okay... you developed a new character set... that's great. How's the browser supposed to know anything abou it?
Maybe just use UTF-8 which should support all of that and other languages as well and stop boxing yourself into a fixed charset.

Boolean Search problem with the "&" character

I need to perform a Boolean search and include names such as "John Wiley & Sons", "R & D", for example, that have the "&" character in it. The problem is that Acrobat considers the character "&" as an "AND". I have tried to use "\&" but it didn't work. Does someone know if it is possible to consider "&" as a character, instead of a logical operator, in a Boolean search, and if yes, how?

I've already done it.
Do you think this will help?
I doubt that Apple will listen to us. Users with a problem that occurs quite a lot.
