Ignoring case in Hashtable key names

Is there any way to check a Hashtable for a key value (which is a string) but to ignore the case of the letters in the string?
if(hashtable.contains(keyValue)){ .... }
returns false if the string keyValue has different capitalization from the key in the hashtable.
Thanks

No, if you want to do it by subclassing Hashtable (incidentally, why Hashtable rather than HashMap?) then you want to override the put, get, contains, and remove methods to call String.lowerCase() on the key. Sylvia's suggestion was to insert a wrapper around String into the map rather than to subclass the map.

Rename hashtable keys

I need to rename some keys in an Hashtable, and i'm wondering if there are "better" ways than creating a new Hashtable and copying the values into it with different key names.

About using HashMap instead of Hashtable i'm not sure
i can do so, because i'm just modifying a part of a
huge web app and i'd need to make sure the change
doesn't affect other parts. Don't mess with it if you don't have to. I assumed (incorrectly) that this was a new program.
By the way what's the
advantage of HashMap over Hashtable ?HashMap isn't synchronized, and has some additional performance benefits over Hashtable. That doesn't mean that Hashtable is used when you need to synchronize the Map. The Collections class provides a method for that. The main reason is that Hashtable was replaced with HashMap. A new hashtable implementation was not created for no reason. There were problems with the original design. HashMap is a living class and will be updated and improved upon as needed. We can't say the same for Hashtable. The main reason Hashtable is still around is that it is used in too much code in the JDK and elsewhere. A lot of developers still use it and I think that's a huge mistake.

Interactive Reports filter ignoring case

Is there a way to have the built-in interactive report filter ignore case? I am currently passing the 'LIKE' filter to my interactive report to search for employee names. I want it to ignore the case so 'SMITH' would be the same as 'Smith' when doing search.
ie. upper(:P1_NAME) like upper(EMP.NAME)

But I'm not capturing the time. The default format is DD-MON-RR.
This is crazy, I have used other Adhoc tools that didn't treat dates that way.
Seeing as the operators change depending on the data type selected by the user, the option must be controlled in the application. Oracle is excluding it for some reason, but they really need to let the administrator control that.
This is in Interactive Reports. The users don't want to have to format the dates, or anything else. They just want to filter the data to a certain date and the = sign should be allowed. If they are capturing time, then the administrator can truncate the date and make it available via another field/column.

UI Designer, DataModel-View, Element-Search-Filter should ignore case

Hi,
I'm currently working within UI Designer and want to bind elements to my OWL.
After selecting a name space and a BO afterwards, I want to search within the loaded BO meta data.
Doing so, I figured out that the search is case sensitive.
In other words, search for 'node' brings no results, but 'Node' does the job.
Hopefully there are no derivations like 'nOde'
@DevTeam, please do 'ignore case'.
Thanks.

Hi,
I tested in 3.0, there the search is no longer case sensitive. So it seems to be corrected.

SCCM 2012 R2 Compliance Settings and registry key name

Hello,
in my baseline, i need to check if a registry key exists (..i know it's easy using an existential rule type), but i need to use the "LIKE" to compare the key name.
Example: the registry key can have the name "RegKeyName_1" OR "RegKeyName_2" OR "RegKeyName_3" so i need to check something like "RegKeyName%"
How can i do that? I hope it's clear...thanks!

First you read the needed registry key values and then store them to variables, after that you compare these variables and return the value based on your needs.

Ignoring case.................

Hello Experts ,
        I am trybin to read data from infotype table pa0002 . I am accepting the Last name ( vorna ) as input .
I am trying to fetch matching records in internal table USING SELECT QUERY .
But the name (vorna ) is *case sensitive* so in table name can be stored as
Rahul
RAHUL
rahul
If user input is RahuL . Query return zero number MATCHING of records .
My requirement is Query should return all three matching records .
How can i do the comparison of name to retrive all matching records IGNORING THE CASE .
i tried following query
SELECT PERNR VORNA NACHN GBDAT FROM PA0002
    INTO CORRESPONDING FIELDS OF TABLE ITAB
    WHERE upper( VORNA )   = upper( STRU_USERIP-VORNA )
    AND   ENDDA >= SY-DATUM
    AND   BEGDA <= SY-DATUM .
But wont work since UPPER is not allowed ,
can anyone provide solution to this problem .
Your Help will be appericiated .
thks ,
Rushi

hi,
There are few ways to ignore case while selecting values :
1. Have all the records in either Capitals or Small Letters in DataBase Table.
2. Have one extra column with either Capitals or Small Letters to do search.
3. Declare Range Tables.
An Example of Ranges :
a. Range declared for which search criteria is there.
Data : lr_name TYPE RANGE OF fmfint-bezeich,
          lr_name_line LIKE LINE OF lr_name.
Data lt_rfc type table of fmfint,
        wa_rfc type fmfint,
        w_output type fmfint,
       t_output type table of fmfint.
b. i_name is the value entered by user in Search Criteria.
if i_name is not initial.
      lr_name_line-sign = 'I'.
        lr_name_line-option = 'CP'.
        lr_name_line-low = i_name.
APPEND lr_name_line to lr_name.
ENDIF.
c. Select all records.
select * from fmfint into table lt_rfc.
d. Filter records using Loop and where condition
loop at lt_rfc into wa_rfc where
bezeich IN lr_name.
MOVE-CORRESPONDING lw_rfc TO w_output.
        APPEND w_output TO t_output.
        CLEAR: w_output,lw_rfc.
endloop.
now finally you have all records based on input entered in table t_output.

How to get key name from parameter list

hi..
i want string from parameter list.. i hv already created parameter list like
ADD_PARAMETER (param_list_id, 'EMPID', TEXT_PARAMETER,'123');
ADD_PARAMETER (param_list_id, 'EMPNM', TEXT_PARAMETER, 'ABC');
ADD_PARAMETER (param_list_id, 'EMPADD', TEXT_PARAMETER, 'XXX');
i got value like '123' ,'ABC', 'XXX' using
eg. get_parameter_attr(param_list_id,'EMPID',aprmlist,avalue)
but i want key name like 'EMPID' , 'EMPNM', 'EMPADD' from param_list_id
is it possible to get this key name from parameter list ???
Thanks...

I cannot think of a way to do that. The code that reads the list is supposed to know the key names. That is sort of the point with parameter lists. If you need to have parameter lists that can be interepreted by some code that doesn't know about a specific list but knows how to interpret it by inspecting the key names, perhaps you can specify a separate parameter list with the key names as values and call the keys of that list something generic?

Using a heirachical key name in bean:message

This is sort of an odd requirement but it will help me out greatly if I can find a way to do this.
I am working on creating a JSP which generates vxml. I am using a resource properties file to read in text that I need to speak, or the names of wave files that I need to play. I grab these using a bean:message tag lib call. This all works fine but now I need to extend this app to handle several different States (Kentucky, Ohio, etc) which may or may not have small variations in their verbiage.
Tell me if I am going about this entirely wrong but this is what I think would be nice to do:
I would like to use the name of the key in this form:
"prompt.company.state"
Where an example resource properties file might be like this:
mainmenu.columbia.ky=mainmenu_ky.wav
mainmenu.columbia=MM_Columbia.wav
mainmenu=mainmenu.wavWhat I would like to happen is if I request the key "mainmenu.columbia.ky" it returns the "mainmenu_ky.wav", but if I request "mainmenu.columbia.oh" it would return "MM_Columbia.wav"
The idea is that a company may operate in different states and customize its prompts for that state if custom prompts exist but if they do not exist it uses the default for that company. Also there could be different company names also so if I asked for "mainmenu.northface" I would receive "mainmenu.wav"
This is sort of like localization but I want to have all the keys in one file.
My thought is that I would need to create my own taglib that extends bean:message and then parses the key name accordingly until I find a matching key. My problem is I have no idea where to start when doing that. I am while I have a strong Java background its been almost 4 years since I've worked on a project using it, and all this Struts and JSP and JSTL stuff is quite new to me.
Does anyone have any tips for me? Maybe there is another tag lib out there which does exactly what I need and I just don't see it. Help anyone?

In which case composite primary key allows NULL values in it

Hi to all
In what case composite primary key allows nulls in it.
Let us suppose, I created a composite primary key with 2 attributes.
CREATE TABLE sample
BNK_Id NUMBER(6),
BNK_Name VARCHAR2(20),
CONSTRAINT BNK_Id_Name_PK PRIMARY KEY(BNK_Id,BNK_Name)
When it allows null values in it.
thanks in advance

Are you sure that your instructor was not talking about unique keys? As Solomon said, a primary key always implies not null on all of the columns of the PK. However a unique key does not automatically imply not null, and can have nulls in a column as long as the values in the populated columns are unique.
SQL> create table test (
2     id number,
3     pid number,
4     descr varchar2(10));
Table created.
SQL> alter table test add constraint test_unq

Table altered.
SQL> insert into test values (1, null, 'desc1');

Why Hashtable class name is like this instead of HashTable

I have a doubt in Collections, why Hashtable class name is like this, because, Every class name is start with CAPS like, ArrayList, SortedSet, etc. then the second name first letter should be in CAPS.
Is that any special for that. Can anyone clear my doubt
Thanks in advance.

Mixed case in column & table name

Hi,
How can tell SQL to use mixed case for column & table name?
For example:
create table PerNode (netId number, nodeId number);
select netId, nodeId from PerNode;
The above statements automatically made to upper case. But I wanted to retain the case sensitiveness in the column & table names.
I know a way by including the names in double quote in the case will make this to retain the case.
But I don't want to give all the time the column & table names within double quote.
What I wanted to know is that is there any ALTER kind of statement will make the SQL to use the case I use in the name of the column & table.
I greatly appreciate your advice.
Thanks,
--JK

Oracle column names and table names are case insensitive unless you enclose them in quotes.
Unless you want to have two tables, one called PerNode and one called pernode or some such, I'm not sure what benefit case sensitivity would have. One can certainly use mixed case SQL statements in stored procedures and ad-hoc SQL for readability-- only in the Oracle internals is everything changed to upper case.

In the case without primary key

Hi experts,
In the case without primary key, we can define a primary key?
In the case
Source: SQL Server 2000
Target: Oracle 11.2.0.3
When both the source and target does not have primary key.
Thank you

ITunes ignores the "The" in artist names, but...

iTunes ignores the "The" in artist names, but is there a way you can get it to ignore "The" is other languages, such as "Les" for French and "Die" for German?

The simple answer is Yes, but you will have to do it manually for each song.
Select the song that contains the "Les" or "Die" and right click and select get info.
Go to the sorting tab.
The second row has artist and sort artist.
You want to keep the "artist" box the same and under the "sort artist" box, type in the name without "Les" or "Die"
iTunes does this automatically for some words such as "A", "An" or "The"
but if you want it done for other words, you have to do it manually.
Hope this helps.

When sorting, Itunes ignores "The" of my artists names

When sorting, Itunes ignores "The" of my artist name.
Is it normal?
Like "The Offsprings" is sort with my "O" artist.
Is there a way that I tune would recognize it?

Ok but its weird, itunes recognize The on my bros laptop and not on mine.
