Group using the order of rows
Hi allone of my friends asked me a question and I think it's possible but how?
without using PLSQL, can it be done by sql?
We have a table and its data like this:
X Y
----------
A S
B S
C S
D T
E T
F S
G S
H RI mean, for this example, A, B and C Archives is a group, D, and E are another group and E and F are one group to another. as you see ABC records and EF has same value Y (which is S) but I would like to assume they are different groups because of the order.
If I give a number of groups, it looks like this:
X Y
----------
A S 1
B S 1
C S 1
D T 2
E T 2
F S 3
G S 3
H R 4PS: we do not want just sql, plsql
If you don't care about the group being sequential numbers:
with t as (
select 'A' x,'S' y from dual union all
select 'B','S' from dual union all
select 'C','S' from dual union all
select 'D','T' from dual union all
select 'E','T' from dual union all
select 'F','S' from dual union all
select 'G','S' from dual union all
select 'H','R' from dual
)
select x,
y,
row_number() over(order by x) - row_number() over(partition by y order by x) rn
from t
order by x
/
X Y RN
- - ----------
A S 0
B S 0
C S 0
D T 3
E T 3
F S 2
G S 2
H R 7

Activate search resource group using the string key
Hi all
RIM has provided APIs (Resource Bundle) to support the localization of the applications. We are able to use it
ResourceBundle.getBundle(BUNDLE_ID, BUNDLE_NAME).getString(key);
He expects int key and generated dynamically by Blackberry. There are 2 cases.
- Local labels, we are aware and we can provide keys for those who, for the latter is no problem.
- From backend error codes. This is not a definitive list. This is the string value. But we cannot find the resource group by using this key of type string. We have to check what the error code and create the key to this and allows to retrieve the label.
if(errorCode.equals("SOME_ERROR_CODE"){ Dialog.alert(LanguageResource.getString(SOME_ERROR_CODE)); } else if (errorCode.equals("ANOTHER_ERROR_CODE"){ Dialog.alert(LanguageResource.getString(ANOTHER_ERROR_CODE));}To avoid this check, we thought that if this was possible.
String msg = LanguageResource.getString("SOME_ERROR_CODE")); if (msg == null) // Label not found Dialog.alert(LanguageResource.getString("GENERAL_ERROR"); else Dialog.alert(msg);Now, API provides no support for this, is the solution to create the own property file and load them but I think that the Blackberry does support playback of the file as Java Standard properties or may be something else. The same reflection API is not supported in Blackberry up to now, there may be support in the future. This could allow to dynamically use the variable as the key name.
Someone did it faced simular situation and made a work around? All entries would help.
Kind regards
Sandeep
Edited: updated information on option of the reflection API.
It will never take in charge of reflection as the baseline for BB Os is J2ME and therefor java 1.3/1.4
you will have to translate the error to the resource key string yourself.

Cannot create groups using the API
Hello
I have an approval workflow for the creation of a new organization and it works fine. Once the final level of approval is finished, I should create a new org and three groups within the IOM. My adapter creates the new organization successfully. However, I get exception when I try to create groups. Is someone can you please tell me what is the question. I assigned all group permissions to the users group on the approval of the application. Here is the snippet of code with the exception I get:
HashMap < String, String > orgMap = new HashMap < String, String > ();
orgMap.put ("Organizations.Organization name", orgName);
orgMap.put ("Organizations.Type", "Organization");
long orgKey = orgOper.createOrganization (orgMap);
System.out.println ("new agency created");
HashMap < String, String > groupMap = new HashMap < String, String > ();
groupMap.put ("Groups.Group name" orgName + "Admin");
long adminGroupKey = groupOper.createGroup (groupMap); -It's the line, I get the following exception

I used the following link and I was able to create groups based on these steps. However I have a question, in the initialization block SQL SQL has a variable name,
Select "GROUP «groupname...»» ». How is the presentation layer knows that the name of the variable 'GROUP' is attributed to membership in a group? Thank you.
http://obieeblog.WordPress.com/2009/06/18/OBIEE-security-enforcement-%E2%80%93-external-database-table-authorization/Griup is a session of the system variable. As soon as you crush with block values init, same value will be overwritten at each location.

How to use the order by clause
Hi Al
order_tracker1 is a tabular_block that I use this to search I want to order by when I search by serch_value
Please guide
The code given is used to find
declare
l_where varchar2 (4000);
Start
If: search_type = "ALL" then
l_where: = ' id | party_name | COMMENT1 | del_date like "%' | : serch_value | » %''' ;
on the other
l_where: =: search_type |' as "%' | : serch_value | » %''';
end if;
set_block_property ('order_tracker1', default_WHERE, l_where);
go_block ('order_tracker1');
execute_query;
end;
Thanks and greetings
Vikas SinghalHai,
Change the line set_block_property ('order_tracker1', default_WHERE, l_where); TO
set_block_property ('order_tracker1', default_WHERE, l_where |) "order by serch_value");
or in time design, you can give in the palette of the ORDER BY Clauesproperty.
or you can write to set_block_property (ORDER_BY, 'order_tracker1', 'serch_value');
Kind regards
Manu.

I have following requirement, please guide me.
1. create a list of values with 2 fields, Code and Description

I could not figure out how you pulled your expected results, especially the last column. I guess that your problem I have several prod_id table productline / salesline. If a group of prod_id in these table should solve your problem. Something like that

How to check for charts grouped using the FrameMaker API?
I have a page with bundled graphics frame and also other graphic objects that are not consolidated or are grouped into a different set. How can I check if all the objects in an image are grouped in one package?
Michael is correct. Specifically, the graphics have a FP_GroupParent property, which returns the ID of the FO_Group object that the graphic is in (if any). If the graph is not grouped, I believe that this property returns a value of zero. Thus, all graphics within a group will have the same value for FP_GroupParent.
Note that you can combine both groups, which then makes things much more complicated. A FO_Group object also has a FP_GroupParent property that theoretically allows an unlimited amount of group nesting. I hope that you don't have to deal with that.

Behavior on the order of the selected line group
When you use a GROUP BY clause with one or several columns, the results will be in the sorted order of GROUP columns (default) or we will use the ORDER BY clause?Hello!
Use ORDER BY, GROUP BY my using an algorithm of hash, so not necessarily rows will be sorted appropriately.

And my another problem here... I don't know why my first clue didn't work...Probably the syntax. The main indicator uses parentheses, as

You can also consider using the y indicator (if you must use a hint) for several tables - beware, it is MUCH easier to do worse performance with this suspicion using the order of the tables in the FROM clause in left to right
/*+ select /*+ ordered */ * from table1, table2, table3 . . . */How I create index will affect how it works?
How the index was created probably won't affect how it works. Indexes can be created using constraints and directly with the CREATE INDEX command. The creation of the index should not be as important as its defined characteristics: index type, columns, etc.

What's the point of having several columns in the ORDER BY clause?
DB version: 10 gr 2
When you use the ORDER BY clause, the lines are always sorted by the first column in the ORDER BY clause. So, what's the point of having several columns in the ORDER BY clause (I always see this in production codes)?
For the below SQLs' schema SCOTT, result sets are always classified according to the first column ename. When I added use asc and desc of employment, does not change the result set.

But if I want to get the family names in descending order when there are two very old person, then I will add the second column in the order by clause

The value of the PropFlags using the API
Hello
I created a new group using the c# API calls. I need to ensure that the new group is not deleted. So I tried using the SetFlag method to set these property flags.
The code snippet is as
userGroup = eng. NewUser (null);
userGroup.LoginName = "Test";
userGroup.AsPropertyObject (). Flags ("PropFlags_NotDeletable", 0x1, 0x400000);
userGroup.AsPropertyObject (). Flags ("PropFlags_NameNotEditable", 0x1, 0x400000);However, the newly created group doesn't have these flags set.
How can I go on the definition of these indicators?
Thank you
Arun
You pass incorrect arguments to the function flags. The first parameter is the string to search for the property you want to set flags on. In this case, pass an empty string to reference the user object. The second parameter specifies the options for the function. In this case you need anything. The third parameter specifies the desired flags set on the property. You must pass the combination of indicators (PropFlags_NotDeletable |) PropFlags_NameNotEditable). If you remember the flags feature, it will overwrite the flags that you set in previous calls.
userGroup.AsPropertyObject (). Flags ("", 0 x 0, PropFlags_NotDeletable |) PropFlags_NameNotEditable);
