LC_COLLATE with dotfiles at top, then case-insensitive sorting

Hello,
I would like to have the following sort order in file managers or when using the "ls" command:
1. dotfiles should be on top
2. other files should follow but case-insensitive
For (1) LC_COLLATE=C works, but it then sorts the remaining file case-sensitive
For (2) e.g. LC_COLLATE="en_US.UTF-8" or de_DE.UTF-8 works.
Is there a locale that fits to my needs? If not, is it possible to edit a locale or create custom rules?
Thank you!

Y = Opportunity Revenue
X = Month
The report is a 4-month forecast, but not using built-in Forecasting that CRMOD uses; this report uses the Forecast checkbox in an opportunity to determine if the oppty should be on the forecast report, then grabs the overall Oppty Revenue from that same region of the Oppty (not using line/Product level revenue field).
The report uses a table and above that a chart with 3D cylindrical output where each press model (derived from a field in the Oppty header) is a different color (I'm letting Analysis defaults set the colors for each product).
My boss wants to sort the colors from smallest model size to largest model size for consistency sake and to make the chart easier to comprehend with a glance.
Is this even possible? I could see sorting by revenue size, but that's not always the best indicator (as some used larger presses may sell for less than new smaller ones).
Any ideas?
Thanks,
Andy

ADF table: case-insensitive sorting

I have an <af:table> that uses a SortableModel as it's data source. I have sorting enabled on the table, but it's sorted according to case sensitivity.
My data source has mixed case, and I'd like to be able to sort regardless of case. Is there anyway to change the behavior so it does a case-insensitive sort instead?
Thanks

In case anyone else is looking for this, I went ahead and wrote an extension of CollectionModel that performs a case insensitive sort on String objects. I'm posting it here in the hopes it will help others in the same jam I was. It would really have been helpful if Oracle had made the source code to SortableModel available. I hope I did things properly with the rowKey stuff since there are no examples to work from.

How to make a sortable column in a table to do a case insensitive sort ?

Hi :
I am using Jdeveloper Studio Edition Version 11.1.1.1.0 and my table columns are sortable but i want to make sure that it case insensitive sort ,for example if i have following column values :
abc,def,ABC,ghi
Sorted results should not be likes this : abc,def,ghi,ABC
instead of this it should be like this : abc,ABC,def,ghi
Please let me know more about it.
Thanks
AN

Dear,
I'm using the same configuration, Could u tell me how did u done the sort in a column in any case.

Case insensitive selects with 'like'

I use a 10g database (10.2.0.2 same behaviour with 10.2.0.1). What we want is case insensitive selects with 'like' operator in the where clause. NLS_COMP is set to 'LINGUISTIC' and NLS_SORT is set to 'BINARY_CI.
In a table we have two columns one of type 'varchar2' one of type 'nvarchar2'. The databases national character set is set to UTF8. Case insensitive sorting works with both columns. Select statements with '.... where varchar2col like '%r%' returns also values with upper case 'R' values (that is what I expect).
The select statements with '.... where nvarchar2col like '%r%' however does not return the row with upper case 'R' values.
I used SQL*Plus: Release 10.2.0.3.0 and other clients and the behaviour is the same so
I think it is not client related.
Is that a known issue or is there any other parameter to set for UTF8 nvarchar columns?
Any hint is very much appreciated! Here are the nls settings in database, instance and session:
DPARAMETER      DVALUE IVALUE SVALUE
NLS_CHARACTERSET WE8ISO8859P1
NLS_COMP      BINARY LINGUISTIC LINGUISTIC
NLS_LANGUAGE      AMERICAN AMERICAN AMERICAN
NLS_NCHAR_CHARACTERSET UTF8
NLS_RDBMS_VERSION 10.2.0.1.0
NLS_SORT BINARY BINARY_CI BINARY_CI
NLS_TERRITORY      AMERICA AMERICA AMERICA

OK. Found out what the problem is. It is obviously the client.
While using the instant client and setting the parameters (NLS_SORT=BINARY_CI and NLS_COMP=LINGUISTIC) as environment variables does not work correctly, at least not for nvarchar2 fields. The nls_session_parameters show the correct values, but selects with 'like' operators in the where clause do not return case insensitive. Issuing the 'alter session' commands and again setting the nls parameters solves the problem.
Using the full client installation also works, in case the parameters are set in the registry on windows systems. With the full client it it not necessary to issue the 'alter session' commands again.
So obviously the problem is instant client and nvarchar2 field related. That's too bad....

Intermittent oracle errors with case-insensitive searches

Hi
I have a table with several columns, two of them are indexed with oracle text.
When I ask queries containing "CONTAINS"-clauses against these columns everything works great. However I have a few other columns in table that I want to run case-insensitive comparisons with.
So I enable case-insensitivity:
ALTER SESSION SET NLS_COMP=LINGUISTIC
ALTER SESSION SET NLS_SORT=BINARY_CI
Now I suddenly start getting intermittent errors.
When I call a query:
SELECT
FROM
article_table at
WHERE
CONTAINS(searchfield , '%MEAT%') > 0
Sometimes it works, but sometimes I get:
ERROR
ORA-29902: ett fel inträffade när rutinen ODCIIndexStart() kördes
ORA-20000: Oracle Text error:

Anyone knows what is going on? Is this bug? Is there a fox for it?
Thanks for any help anyone can provide.
/Kjell

Clearly that's a bug. Unless anyone here recognizes it and can point you to the bug/patch number I would strongly recomend you to take it to oracle support.
Incidently, doing a search for '%MEAT%' is usually a bad idea. Leading wildcards will disable the use of the index on the $I table, so unless you're using the SUBSTRING_INDEX option such searches will usually perform very badly. They shouldn't cause "internal errors", of course.

How can I double sort my message list? Sort then a sub sort

I would like to sort my messages by date (or some other category), then sort by another category while keeping the first sort. In other words, a sort within a sort. I'm using TB 24.6.0

example:
If you select
View > Sort by > select: 'From' and 'Descending' and 'Group by Sort'
You will get a list of names Z at top and A at bottom, with a sublist of emails sorted with newest at top.
Changing the sort selection from Descending to Ascending will put the names sorted A at top, but the dates per person will be oldest at top.
As I prefer the emails to be in date newset on top, it means I have to select to have the order of 'From' with A at bottom; depends on your preference.
Additional:
If you start by selecting: 'From' and 'Descending' and 'Group by Sort'
then change sort to 'Ascending', you may notice no change until you hover the mouse over the entire list, this is a known bug.
Please feel free to Vote for this bug, you may need to logon / tregister.

Insensitive Sort in DataGrid

Hi All,
Is there a property that can be set to provide for a
case-insensitive sort? or do I need to create a custom sort compare
function?
Thanks,
Tom

I imagine the datagrid is resetting when you reassign its dataProvider.
If you use a single instance of XMLListCollection as the dataProvider
for the grid and assign your XML data to the XMLListCollection's
'source' property, your data will update without the grid resetting.
Here's a very simple example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
   xmlns:mx="http://www.adobe.com/2006/mxml"
   layout="vertical"
   creationComplete="setDataProvider()">
   <mx:Script>
      <![CDATA[
         import mx.collections.XMLListCollection;
         [Bindable]
         private var xmlOriginal : XML =
            <root>
               <item name="Alpha" letter="Z"/>
               <item name="Beta" letter="P"/>
               <item name="Gamma" letter="X"/>
               <item name="Delta" letter="P"/>
            </root>
         private var xmlUpdated : XML =
            <root>
               <item name="Alpha" letter="F"/>
               <item name="Beta" letter="U"/>
               <item name="Gamma" letter="A"/>
               <item name="Delta" letter="P"/>
               <item name="Epsilon" letter="F"/>
            </root>
         private function setDataProvider() : void
            dataGrid.dataProvider = new XMLListCollection( xmlOriginal..item );
      ]]>
   </mx:Script>
   <mx:DataGrid
      id="dataGrid"/>
   <mx:Button
      label="Simulate Update"
      click="XMLListCollection( dataGrid.dataProvider ).source = xmlUpdated..item"/>

Case Insensitive Search coupled with "LIKE" operator.

Greetings All, I am running Oracle 11gR1 RAC patchet 25 on Windows X64.
This db supports and application that requires case insensitive searches.
Because there are a few entry points into the db I created an "after login" trigger:
CREATE OR REPLACE TRIGGER MyAppAfterLogon_TRGR
AFTER LOGON
ON DATABASE
DECLARE
vDDL VARCHAR2(200) := 'alter session set nls_comp=''linguistic''';
vDDL2 VARCHAR2(200) := 'alter session set nls_sort=''binary_ci''';
BEGIN
IF ((USER = 'MyAppUSER') OR(USER = 'MyAppREPORTINGUSER')) THEN
EXECUTE IMMEDIATE vDDL;
EXECUTE IMMEDIATE vDDL2;
END IF;
END MyAppAfterLogon_TRGR;
This ensures that everyone connecting to the DB via any mechanism will automatically have case insensitive searches.
Now, to optimize the know queries I created the standard index to support normal matching queries:
select * from MyTable where Name = 'STEVE';
The index looks like:
CREATE INDEX "CONTACT_IDX3 ON MYTABLE (NLSSORT("NAME",'nls_sort=''BINARY_CI'''))
This all works fine, no issues.
The problem is when I write a query that uses the "LIKE" operator:
select * from MyTable where Name like 'STEV%';
I get back the record set I expect. However, my index is not used? I can't for the life of me get this query to use an index.
The table has about 600,000 rows and I have run gather schema stats.
Does anyone know of any issues with case insensitive searches and the "LIKE" clause?
Any and all help would be appreciated.
L

I think there is issue with your logon trigger :
"IF ((USER = 'MyAppUSER') OR(USER = 'MyAppREPORTINGUSER')) THEN"
it should be :
IF UPPER(USER) = 'MYAPPUSER' OR UPPER(USER) = 'MYAPPREPORTINGUSER' THEN
because user name stored in Upper case. Check and try.

Making ADF Search case insensitive without using Execute with Params??

I have a ADF search page baed on VO. I'm not Execute with Params form, instead i'm using normal ADF search page. Is it possible to make the search case insensitive?? if yes, how to do that?

Ok, i'll try to find out the SRDemo application using ADF BC.
And In Execute with params form,i'm already using UPPER on both the sides of where clause.
Say my VO query is like
select <table name>,...
from fnd_tables t,fnd_applications a
where a.application_id = t.application_id
and upper(t.table_name) like upper(:EntityName) || '%'
Then i created the ADF paramaters form by dragging and dropping the Execute with param from data control pallette.. when i run this page and do the search, it throws the error given in my second update...Any clue why that error is coming?
Thanks

5.0 won't work - extensions message is "localized string not found". When I force it to try to load a new window it shows a gray screen with the bookmarks on top then immediately closes and wants to report the error. Has been this way since 5.0 came out.

I first tried downloading Safari when the 5.0 update came out last year. When I choose the app in the dock, I get the blue top bar (Safari, File, etc) but nothing else loads. I uninstalled the app and tried again several times, but no success. For over a year now I've used Firefox as a result. Today I thought I'd try again, but same results. When I choose "new window" in the file menu, I get a small gray window with my bookmarks on top, then in a few seconds, the app quits unexpectedly and the report an error screen appears. I've unchecked all the languages in the information area for the app, cleared all history, cookies, and cache. Still the extensions tab in the preferences area has "LOCALIZED STRING NOT FOUND" in 4 places. It won't show what that means when I click the "?". Will I ever be able to use Safari again?

Perform the suggestions mentioned in the following articles:
* [[Firefox is already running but is not responding]]
-> Profile in use
* [http://kb.mozillazine.org/Profile_in_use]
Check and tell if its working.

Search on text with diacritic, and case insensitive

Hello to all,
I'm using this condition in a query on XML:
field[contains(@value, "gangesa" )
If @value= 'Gaṅgeśa' I'd like to get this record also by using the word: "gangesa" So I need to map:
ṅ = n
ś = s
And do it in case insensitive. Somebody can help me?
Thank you,
Cristian

ALTER SESSION SET NLS_COMP=LINGUISTIC;

Case-insensitive Search with Search Form

I am using a Search Form with a UIX Page. One of the issue that need to be resolved is to be able to do case-insensitive search for text information stored in some database columns. Please advise me how to implement case_insensitive search with JDeveloper's Search Form.
Thanks in advance,

Hi Qian,
This article (below) by Steve Muench explains how you can customize Query by example behaviour of ADF BCs and if you really want, how to create your own ViewCriteriaAdapter (but you don't have to go quite that far - luckily :) ).
http://radio.weblogs.com/0118231/2005/02/10.html#a492
Here is what I did. I implemented the following method in my base view object class (MyBaseViewObject). Note that this code is based on a piece of code that Steve posted on his blog (http://radio.weblogs.com/0118231/stories/2003/07/11/implementingAViewCriteriaAdapterToCustomizeQueryByExampleFunctionality.html); originally an example about creating your own ViewCriteriaAdapter.
Since applyViewCriteria(oracle.jbo.ViewCriteria) is used by the query-by-example mechanism you're able to "intercept" the ViewCriteria on "it's way in". After that the standard ViewCriteria does it's job as ususal and generated the where clause when required.
public void applyViewCriteria(ViewCriteria vc)
     if( null == vc || vc.size() == 0 ) super.applyViewCriteria(vc);
     ViewCriteriaRow criteriaRow = (ViewCriteriaRow)vc.first();
     StructureDef def = criteriaRow.getStructureDef();
     AttributeDef[] attrs = def.getAttributeDefs();
     System.out.println(getClass().getName() + ": applyViewCriteria()");
     boolean bFirst = true;
     do{
       if(vc.hasNext() && !bFirst) criteriaRow = (ViewCriteriaRow)vc.next();
       criteriaRow.setUpperColumns(true);
       for (int j = 0, attrCt = attrs.length; j < attrCt; j++)
         String criteriaAttrVal = ((String)criteriaRow.getAttribute(j));
         if (criteriaAttrVal != null && !criteriaAttrVal.equals("") && !JboTypeMap.isNumericType(attrs[j].getSQLType()))
          criteriaRow.setAttribute(j,criteriaAttrVal.toUpperCase());
       bFirst=false;
     }while(vc.hasNext());
     super.applyViewCriteria(vc);
NOTE that doing this makes all your views case insensitive (to vc search) you may want to implement more functionality in your base view object to set whether a view is in case insensitive mode or not.
ALSO that flag will not be passivated (if I remember correctly - someone correct me if I'm wrong) so you'll have to add that flag to the passivated data.
Cheers!

I have loaded and reloaded Reader 9. I cannot open a pfd document.      I can save it to desk top then open it via a drop down box that has a "open with Adobe Reader 9". How can I avoid having to do this?

I have loaded and reloaded Reader 9. I cannot open a pfd document.      I can save it to desk top then open it via a drop down box that has a "open with Adobe Reader 9". How can I avoid having to do this?

Hello Michael,
Thank you for your response. My operating system is XP. When I try to open a pfd document I just get a series of letters and symbols in a dialog box. The top of the box says "select the encoding that makes your document readable". I can choose Windows, MS-Dos, or other (there is a long list to choose from). None seem to make a difference. If I save the document to my desk top I can right click on it and choose an option "Open with AdobeReader 9" and it opens fine.
Thank you,

Subject: I have loaded and reloaded Reader 9. I cannot open a pfd document.      I can save it to desk top then open it via a drop down box that has a "open with Adobe Reader 9". How can I avoid having to do this?
Hello:
What operating system does your computer use? What happens when you attempt to open a PDF document rather than saving it first? Please include any/all error messages. Also, have you tried opening documents from other locations or just one in particular?
Thanks,

Mapping with case insensitivity in Filter operator expression

I need to import data from an ODS into DW table.
How can I set this before a certain mapping is run to make it case insensitive?
execute immediate 'alter session set NLS_SORT=BINARY_CI';
execute immediate 'alter session set NLS_COMP=LINGUISTIC';
Thanks,
JGP

Hi,
Use upper(column) in the filter expression.

LC_COLLATE with dotfiles at top, then case-insensitive sorting
