How to define the condition in the analytic function
Oracle 10g version
Hi all
I have the following data samples:
Examples of data
WITH DATA AS
(
SELECT 100 case_id, next_date, to_date('01-feb-2015','dd-mon-yyyy') UNION double, ALL crt_date to_date('01-jan-2015','dd-mon-yyyy')
SELECT 100 case_id, next_date, to_date('01-mar-2015','dd-mon-yyyy') UNION double, ALL crt_date to_date('01-feb-2015','dd-mon-yyyy')
SELECT 100 case_id, next_date, to_date('01-apr-2015','dd-mon-yyyy') UNION double, ALL crt_date to_date('01-may-2015','dd-mon-yyyy')
SELECT 100 case_id, to_date('01-jun-2015','dd-mon-yyyy') next_date, to_date('01-apr-2015','dd-mon-yyyy') crt_date FROM dual
)
SELECT wagneur, MIN (next_date) OVER (PARTITION BY case_id) min_dt_analytical
,(
SELECT MIN (next_date) DATA dd
WHERE dd.case_id = d.case_id
AND dd.next_date > crt_date
) min_dt_sub_query
DATA d
;
My question is that I get min_dt_sub_query using sub query but I want to use the analytical instead of query sub function so I created min_dt_analytical column, but I do not have how to give the condition that is AND dd.next_date > crt_date analytical so that I can get the same result as min_dt_sub_query data accordingly. Thanks in advance

Do not know if I understood your needs... but... something like that?
WITH DATA AS (SELECT 100 case_id, next_date, to_date('01-feb-2015','dd-mon-yyyy') UNION double, ALL crt_date to_date('01-jan-2015','dd-mon-yyyy')
SELECT the 100 case_id, next_date, to_date('01-mar-2015','dd-mon-yyyy') UNION double, ALL crt_date to_date('01-feb-2015','dd-mon-yyyy')
SELECT the 100 case_id, next_date, to_date('01-apr-2015','dd-mon-yyyy') UNION double, ALL crt_date to_date('01-may-2015','dd-mon-yyyy')
SELECT 100 case_id, next_date, to_date('01-apr-2015','dd-mon-yyyy') double crt_date to_date('01-jun-2015','dd-mon-yyyy'))
SELECT d.
MIN (next_date) OVER (PARTITION BY case_id) min_dt_analytical
MIN(CASE WHEN next_date > crt_date THEN next_date ELSE NULL END) OVER (PARTITION BY case_id) AS min_dt_sub_query2
DATA d;

How to define the rules of navigation in faces - config.xml dynamically?
In jdev 12.1.2 I am studying and performing the adf faces demo (12.1.2 version).
I am trying to implement the function of navigation like this:
1. in the navigation tree in the left panel of the accordion will show the features of an application which is read from database tables;
2. When you click on a node in the navigation tree, a corresponding function/page will be launched in the Panel to the right of the home page;
3. the navigation tree nodes display names and information pages target will be resident in the database tables and will be read in my case, the control of data bindings.
and now I know, the click action was executed in this file in the demo: componentGallerySideBarTree.jsff:
->action = "#{stamp.actionOutcome}"
< af:tree id = "tree" value = "#{attrs.menuModel}" var = "stamp" = "single" rowSelection fetchSize = "200" "
Summary = "#{uploading." Summary}"disclosedRowKeys =" #{attrs.menuModel.foldersTreeState} "autoHeightRows = '0'"
displayRow selectedRowKeys = "#{attrs.menuModel.selectionState}" = "selected" "
contentDelivery = 'immediate' emptyText = "there are no demos for this category.
styleClass = "AFStretchWidth" >
< f: facet name = "nodeStamp" >
< af:panelGroupLayout id = "nodePgl" >
< af:image source = "#{stamp.ico}" styleClass = "GalleryIcon" shortDesc = "Image of a tree node" "
ID = "nodeImg" / >
< af:switcher facetName = "#{stamp.children == null?' leaves ': 'notLeaf'}" id = "nodeSw" > "
< f: facet = "journal batch name" >
< af:link id = text = "#{stamp.label"leafLink"} '"
shortDesc = "#{stamp.label} #{stamp.deprecated eq 'real'?" (not recommended) " :"} »
action = "#{stamp.actionOutcome}"
inlineStyle = "#{stamp.deprecated eq 'true'?-style: italic; color: gray':"} ' "
selected = "true" >
< af:target execute="@this"/ >
< / af:link >
< / f: facet >
< f: facet name = "notLeaf" >
< af:outputText id = value = "#{stamp.label"notLeafText"} ' shortDesc =" #{stamp.label} "/ >"
< / f: facet >
< / af:switcher >
< / af:panelGroupLayout >
< / f: facet >
< / af:tree >
and the value of actionOutcome was entered in this file DemoConfusedComponentsMenuModel.java:
(for the case of the confused component navagation tree folder)
private TreeModel _initConfusedComponents()
{
Confused components
The list < DemoItemNode > confusedComponentsNodes = new ArrayList < DemoItemNode >)
{
{
..
Add (new DemoItemNode ("Tabs", "/ confusedComponents/tabs.jspx","/adfdt/panelTabbed.png","confused.tabs"));
Add (new DemoItemNode ("iterators","/ confusedComponents/iterators.jspx","/adfdt/iterator.png","confused.iterators" ""));
}
};
DemoItemNode confusedComponentsGroup = new DemoItemNode ("Often confused", "/ images/folder.png", confusedComponentsNodes);
List ConfusedComponentsList = new ArrayList();
confusedComponentsList.add (confusedComponentsGroup);TreeModel confusedComponents = new ChildPropertyTreeModel (confusedComponentsList, _CHILDREN);
Return confusedComponents;
}In addition, there are elements in faces-config .xml to define the rules of navigation for the actions 'by clicking on the tree node.
<>navigation-case
< from outcome >confused.iterators< / de-results >
< to view - id > /confusedComponents/iterators.jspx< / to-view-id >
<!-< redirect / >->
< / navigation-case >
So, I can add a new entry in the navigation tree, like this:
1. in DemoConfusedComponentsMenuModel.javaof the file: Add
Add (new DemoItemNode ("Iterators", "/confusedComponents/cms.jspx","/ adfdt/iterator.png","confused.cms" ""));
2. in the file faces - config.xml, add:
<>navigation-case
< from outcome >confused.cms< / de-results >
< to view - id > /confusedComponents/cms.jspx< / to-view-id >
<!-< redirect / >->
< / navigation-case >
and it works!- I have successfully added a new node in the navigation tree, called a new page created by myself cms.jspx.
If I implement them using database tables (links datacontrols EO/VO),.
I think I can put action = "#{stamp.actionOutcome}" by links.
But how can I pay the entry in the faces-config file. XML? -That is to say:
How to define the rules of navigation in faces - config.xml dynamically?
Thanks in advance!
ADF 12 c comes with support for JSF 2.0, you can use the implicit navigation feature.
In short: you don't need to add case action property, any set of navigation in the name of the page (and include the path if necessary).
In your case, the name of the action will be: ' / confusedComponents/cms.jspx ' and of course, you can link the action property of method that returns this string.
If you want to add by the case of navigation program, try ConfigurableNavigationHandler.
For example:
Manager of ConfigurableNavigationHandler = (ConfigurableNavigationHandler) FacesContext.getCurrentInstance () .getApplication () .getNavigationHandler ();
handler.getNavigationCases () .put (...);

A question about the analytical function used with the GROUP BY clause in SHORT
Hi all
I created the following table named myenterprise
If I want to find which is the total sales by city? I'll run the following queryCITY STOREID MONTH_NAME TOTAL_SALES ---------- ---------- ---------- ---------------------- paris id1 January 1000 paris id1 March 7000 paris id1 April 2000 paris id2 November 2000 paris id3 January 5000 london id4 Janaury 3000 london id4 August 6000 london id5 September 500 london id5 November 1000
that works very well and produces the expected result, i.e.SELECT city, SUM(total_sales) AS TOTAL_SALES_PER_CITY FROM myenterprise GROUP BY city ORDER BY city, TOTAL_SALES_PER_CITY;
Now in one of my books SQL (Mastering Oracle SQL) I found another method by using the SUM, but this time as an analytic function. Here's what the method of the book suggests as an alternative to the problem:CITY TOTAL_SALES_PER_CITY ---------- ---------------------- london 10500 paris 17000
I know that the analytic functions are executed after the GROUP BY clause has been transformed completely and Unlike regular aggregate functions, they return their result for each line belonging to the partitions specified in the partition clause (if there is a defined partition clause).SELECT city, SUM(SUM(total_sales)) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY FROM myenterprise GROUP BY city ORDER BY city, TOTAL_SALES_PER_CITY;
Now my problem is that I do not understand what we have to use two functions SUM? If we only use one only, i.e.
This generates the following error:SELECT city, SUM(total_sales) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY FROM myenterprise GROUP BY city ORDER BY city, TOTAL_SALES_PER_CITY;
The error is generated for the line 2 column 11 which is, for the expression SUM (total_sales), well it's true that total_sales does not appear in the GROUP BY clause, but this should not be a problem, it has been used in an analytical function, so it is evaluated after the GROUP BY clause.Error starting at line 2 in command: SELECT city, SUM(total_sales) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY FROM myenterprise GROUP BY city ORDER BY city, TOTAL_SALES_PER_CITY Error at Command Line:2 Column:11 Error report: SQL Error: ORA-00979: not a GROUP BY expression 00979. 00000 - "not a GROUP BY expression" *Cause: *Action:
So here's my question:
Why use SUM (SUM (total_sales)) instead of SUM (total_sales)?
Thanks in advance!
:)
In case you are interested, that's my definition of the table:
Edited by: dariyoosh on April 9, 2009 04:51DROP TABLE myenterprise; CREATE TABLE myenterprise( city VARCHAR2(10), storeid VARCHAR2(10), month_name VARCHAR2(10), total_sales NUMBER); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('paris', 'id1', 'January', 1000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('paris', 'id1', 'March', 7000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('paris', 'id1', 'April', 2000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('paris', 'id2', 'November', 2000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('paris', 'id3', 'January', 5000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('london', 'id4', 'Janaury', 3000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('london', 'id4', 'August', 6000); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('london', 'id5', 'September', 500); INSERT INTO myenterprise(city, storeid, month_name, total_sales) VALUES ('london', 'id5', 'November', 1000);
It is clear that thet Analytics is reduntant here...
You can even use AVG or any analytic function...SQL> SELECT city, 2 avg(SUM(total_sales)) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY 3 FROM myenterprise 4 GROUP BY city 5 ORDER BY city, TOTAL_SALES_PER_CITY; CITY TOTAL_SALES_PER_CITY ---------- -------------------- london 10500 paris 17000

How to activate the Sleep function to put the computer to sleep if a program is open?
I have Windows Vista basic on a desktop Dell 530. I found that if I have a program or application running (such as I-tunes or windows media player) then the Sleep function will not put the computer to sleep. How to activate the Sleep function to replace these programs and put the computer to sleep?
Note: This is how it was with windows XP, the Sleep function would put the computer to sleep no matter what was running, he was reliable, if you left the computer and I forgot that you had something running.
Thanks for your help.
Hi kevino4130,
If you disable sharing on your computer (not only the power settings) of media, it should allow him to enter the mode 'sleep'.
See if that does not solve your problem and let us know.

How to use the @accum function in the calculation script
Dear all.
I'm new in essbase - calculation script so don't know how to use the @accum function.
I want the aggregation value of child to parent

100. 10 (+)
100-20 (+)

I'm trying calculation Script
100 = @Accum (@children("100"), jan: Feb);
It works when I use below
100 = @Accum("100-10",Jan:Feb);
Error:-number of Dimensions [1] does not match number of gen/lev [3] office [@Dim]
Don't know how I can roll up to an aggregate value of all the members of the child to the parent.
you do this more difficult it must be. If you want to accumulate up to 100 then you could just make your calc
'100 '.
but that would be only 100, to make the OU any dimension would

SQL using the analytic function
Hi allI want a help in the creation of my SQL query to retrieve the data described below:
I have a test of sample table containing data as below:
State ID Desc
MICHAEL 1 T1
ACTIVE 2 T2
T3 3 SUCCESS
DISABLE THE T4 4
The thing I want to do is to select all the lines with an ACTIVE status in the table but is there is no ACTIVE status, my request will give me the last line with MICHAEL status.
I can do this in a single request by using the analytical function for example, if yes can yiu help me on the request of unpacking.
Kind regards
Raluce
Something like that?
I had to fix it.
with testdata until)
Select 1 id, "T1" dsc "DISABLED" status of Union double all the
Select 2 id, 'T2' dsc, the status "ACTIVE" of all the double union
Select id 3, "T3" dsc, the status of 'SUCCESS' of all the double union
Select 4 id, "T4" dsc "DISABLED" status of double
)Select
ID
dsc
status
of testdata
where
status =
-case when (select count (*) in testdata where status = 'ACTIVE') > 0
then 'ACTIVE '.
Another 'DISABLED '.
end
and)
ID in (select id from testdata where status = ' ACTIVE')
or
ID = (select max (id) in testdata when status = 'DISABLED')
)STATE ID DSC
'2' 'T2' 'ACTIVE '.
Maybe it's more efficient
Select
ID
dsc
status
of testdata
where
status =
-case when (select count (*) in testdata where status = 'ACTIVE') > 0
then 'ACTIVE '.
Another 'DISABLED '.
end
and
ID =)
-case when (select count (*) in testdata where status = 'ACTIVE') > 0
then id
on the other
(select max (id) in testdata when status = 'DISABLED')

How to use the goto function?
How to use the goto function in indesign javascript?
my script begins by chekcing if the input files are present or not... If one of the input files is not present, I want the n function put an end to the operation in the display of the message tht file exists... I was wondering to use goto for tht... then how to use it? or is there an alternative to that?
GoTo is generally frowned upon by the programmers.
The only legitimate use of goto is when you need to escape from a nested loop.
If you need to jump into a routine, use break or simply in return from the current function.
The model currently used by the SDK looks like this:
do { if(condition1 == false) break; if(condition2 == false) break; if(condition3 == false) break; doSomethingReallyCool(); }while(false);
'break' the jumps at the end of the do / while loop that always comes out when you reach the end of it (while (false))
