Asking only once for a parameter...

Post Author: Nightcrawler
CA Forum: Data Connectivity and SQL
Hi,
I have a report which need to select a list of items for a dynamic lookup for the report. I have created two stored procedure in SQL which work in QA. When I link them to a report I get asked for the date range twice. This is because the two stored procedures ask for the date range for them to select data. The parameter names are the same in each stored procedure. Basically I want the screen to ask me for the date range then give me a popup list based on the items. Then pass this to the second stored procedure to run for the report ??
How is best to do this ?
Thanks
Ed

Hi,
No there are no refs in the section expert. Not sure what you mean by in and out but ? The date is passed to the sp but not returned.
It seems everytime I want to do a dynamic pararmeters for the first sp. It asks me for the varaibles but not the ones listed in field explorer.... IE if I link the field explorer fields for the first sp to the subreport it asks for the date twice ?? Once for the first sp ( I can tell this as it has the name of one of the sp fields in the top right of each question) and then again for the paremeters that are in the field explorer - which I have given a description, thus I can tell there the next set.
Surely thou these first parameters are the same ?? Is there a way of changing the priority...
It seems a complex system for something that should be very simple.
All I want is to pass two date values to have a dynamic list of rooms wchih are valid. Then pass the same date variable and the chosen room to the next sp... but prefrable without the duplicate date asking .....
I've just read the subreport linking docs but its doesnt help as everytime you refernace the parameters from the first sp that are shown in field explorer, it asks duplicate questions.
Just to make this clearer - when I say duplicate questions I mean it is obiviously runs the sp first then for those variables. Then it runs the report and asks for the field explorer variables which it has created when I first referanced the sp. Does this make sense ???
Thanks

How to set a payload field value only once for multiple instances selected?

The user needs to set a payload field value and then he can approve the task so the task can continue through the process, that's fine when the user selects one instance and sets the value in the task details section and then clicks the approve button, but how do we achieve the same behavior in a multiple way?, I mean the user can select multiple tasks in the workspace (in this case the details task page is not available and instead the following label appear "Multiple tasks selected") then if the user clicks the Actions drop down -> APPROVE he only gets the message "your request was processed successfully", so how can the user modify the payload field value only once for all the selected tasks so when he clicks APPROVE the value is populated in all the instances selected.
Thanks,
Carlos.

In the action which displays the edit page just set the form idx value before displaying the jsp.

Need to display records only once for that particular group

Hi,
I have a requirement like displaying repeated records only once for that particular group.
For eg, in the emp table, I need to display repeated deptno only once for the particular group of job.
And for the above requirement I have used the below query,
SELECT empno, DECODE (LAG (job, 1) OVER (ORDER BY job), job, NULL, job),
DECODE (LAG (deptno, 1) OVER (ORDER BY deptno), deptno, NULL, deptno)
FROM emp;
Output:
EMPNO     JOB     DEPTNO
7782          10
7934     CLERK
7839     PRESIDENT
7876          20
7788
7902     ANALYST
7566     MANAGER
7844          30
7900
7654     SALESMAN
7698
But in the above output you can find that, say deptno 10 is getting displayed only once, whereas I want that deptno 10 to be checked whether it is getting repeated within the group of JOB and than hide the deptno 10 only if it is repeated within that job group. If not, deptno 10 should be displayed again.
Please help me in this.
Regards,
Shiva

Hi,
Hope the below helps.
SELECT emp_id, job, deptno,
       CASE WHEN LAG(deptno, 1) OVER (partition by job order by deptno) = deptno THEN null else deptno end
FROM empRegards

Why java allow start() method only once for a thread

Hi ,
Why java allows start method only once for thread . suppose
Thread t = new Thread();
t.start();
say at later stage if again we call t.start() IllegalStateException is thrown , even though isAlive method returns false.
Hence the question , why start() method is allowed only once.If you need start a thread , we need to create a new instance.

Really. Why do you think that? Do you have any evidence? It is one of the first things I would think of, personally.Considering that the Thread API doesn't allow you to specify a stack address (only stack size), I think it demonstrates they wanted to remove that capability from their Thread API all together. That missing "capability" makes me believe they want me to believe it's not something I need to worry about when using their API... I think the exact semantics of the Thread class and its methods were driven by how to make it most understandable and usable for their customers. I'm certain this issue was one of many that was given considerable thought during the design and implementation of the JVM and the underlying runtime classes.
Do I have any evidence? No. But if you can point me at some first-hand information on this, I'd love to read it. Most of what I've found is second or third hand accounts. (and I mean that sincerely, not as a smart-ass remark or rebuke of your comments).
On the one hand you seem to think the Java API designers are idiots, on the other hand you think that they should be. I can't make it out.I thought my position was that the Java developers were talented enough to implement platform in whatever way their API called for; hence, the designers made a choice about how they wanted their API to be used by their customers. They decided which capabilities they wanted to include or exclude, and created an API that was consistent with their vision for this technology. While I'm certain technical limitations had an effect on the API design, I certainly don't think the API was dictated by the them.
I think the current design of the Java Thread API was a reflection of their vision to make Threading easier and more accessible to Joe Programmer, not limitations in the implementation. I never said it was wrong or that I could do better... I just said I think they could have done something different if they decided it would have made for a better customer experience. But hey, maybe I'm wrong.

Need to populate value for a KF only once for a combination of characterist

Hello All,
We had a requirement for a report. wherein we need to consolidate the data of the 0FI_GL_4 datasource and a custom table.
both these sources have only 4 fields in common i.e Fiscal Year/Period; Company Code and Pool
in the custom table, for each fiscal yr/period & Pool combination, there is a unique Plan value available.
To consolidate the data, I wrote a routine in the transformation to extract data from the custom table based n the combination of Fisc yr Period, Comp Code & Pool.
However, since 0FI_GL_4 has more than 1 entry for the above mentioned combination that is GL_accounts, document number, etc; during extraction, my plan value is being extracted multiple times to the cube and hence for a fiscal yr/period, cube shows a summation value.
I want the plan value to be picked only once.. please advice

Hi Sneha,
As I understand in your infocube along with the primary key of custom table one more field exists e.g. Document number and due to which the value is getting repeated over multiple lines.
Though all these records are valid but when you are running report on this cube without document number all the plan values are getting aggregated, again this behaviour is also correct.
For your reporting purpost I feel that you need to extract data from the custom table in other data target and then do the reporting on that, wherein the plan value will not be repeated.

Durgesh.

Running a query only once for a report in Reports 6i in a BEFORE REPORT trigger.

Hello all -
I am using Oracle Reports 6i on Windows NT 4.0 SP 6.0.
The report I am converting from Access to Oracle Reports is
rather complex, and features detail by decile (a rank) within
territory (geographical sales area). Also it features a summary
at the bottom of each territory/decile combination which
summarizes not only the territory information, but goes above
that to higher levels like district, region, and national.
With the help of a consultant, we have managed to get the report
almost finished. However, we are running into a snag with the
summary. While my two main queries need to run in the data
model as normal, I would like to run the summary query _only
once_ during the entire cycle of the report, and have the report
fields populated once for the entire report. This is possible
because for a district, the summary numbers are the same on
every page of the report, only the territory information
changes. So by only having the query run once and fill the
report values once, this would save considerably on the report
runtime.
However, I have tried a few different methods but cannot get the
report to recognize the fields in the query, most likely because
they are out of scope at report creation. Does anyone have any
ideas on how I can accomplish this in Reports? Any help would
be appreciated - I hope my question was clear, if not please let
me know.
Thanks,
-Jennifer Prichard

Hello!
You can place in the data model editor formula and placeholder
columns outside of any groups. I think you need for each of your
summary-attibutes a placeholder column and one formula column.
Use the formula column to populate the placeholders via PL/SQL.
Afterwords you can reference the placeholders anywhere you want.

Read config file only once for beans

I want to read onfiguration file Myconfig.cfg with many global values (server IP, port, database URL, pages, etc) I'm using a bean but every time a JSP or servlet create an instance of that bean all the data has to be read form disk...
I know that if I put the code for reading the file in the init() method in a servlet it is called only once, but how do I read those values from another servlet or JSP, ???
What is the best solution...

You can put initiation parameters in your web.xml file and write a servlet that is called on startup. Once the values are read you can put them into the application scope. (i.e. application.setAttribute("jdbcUrl", jdbcUr); )
Then in your JSP pages you can take them out by using the application.getAttribute("jdbcUrl"); method.

Adding list based menu only once for all related pages

Hi,
I have a one level tab application. For a given tab I have 5 different pages. I would like let the end user navigate to these pages via a list region. Currently I have added to all five pages a list region and assigned the same list item to these list regions.
Is it possible that I add this list based menu only once to my application or this is the normal way of doing it?
Is there a way to let

Use page zero.
Add regions containing the lists for each tab to the same region display point on page zero, making each region conditional using a "Current Page Is Contained Within Expression 1..." condition.

Why only once for create recovery media???

When I created recovery discs for my laptop using HP Recovery Manager, I got the message:
You can only create recovery media once for your system. So ensure that you keep it in a safe place
why only once?? what is the problem with creating the same discs again?
what is the difference when creating the recovery discs with the Backup and Restore utils in Windows 7? is it also once only? what is the difference between discs created with Windows 7 versus HP Recovery Manager?

I believe it is due to MS license agreement that only 1 set is allowed. You can of course use a CD/DVD burning program to copy the set you made.
The Recovery set you burn restores the laptop back to factory shipped state. Recovery made with Win 7 utility is an image of the hdd that includes added programs, data ,photos,etc.You also need to burn the System repair disc to use with the backup. You can use it as often as you like.

Label printing should be only once for a material doc number

Hi,
we have a tcode in which if we provide a material doc no. and number of prints..but once we print the labels,
then again if we have to print for the same material doc no..it should not print..instead it should ask for permission to print that number again..is there any option available in scripts to do like this?

try to maintain ztable
                 ztable fields document no , printed...
such that to identify the docu no has been printed previously r not...
select single printed from ztable into printed where docu no = p_document.
    if printed = X
      if it is printed then try to pop up a screen such thst to approve it ....
       else.
     print it strightly.....

With a document open password - is there a way to ask only once per session?

Here's my scenario: User is reading a "password to open" document that contains links to other web pages, etc. The user clicks on a link, goes to the new page, then uses the back button/back key to return to the password protected document, where they must type in the password to open again, and must do this every time they click a link then later attempt to return to the document.
Is there a way around the repeated retyping / reentering / rekeying the password? (My guess is no, but I'll ask anyway). The user did type in their password, most of the time just a minute or two earlier, before they clicked on the link in the password protected document.
P.S. I have a couple other questions, indirectly related (byproducts) to this general topic. I'll post those in their appropriate forum, then edit this post with links to those posts. FYI, the other posts are/will be:
Is there a better way than manually adjusting each and every link in a document to use javascript and repeating that process each time the document is updated, to make links open in new windows, (when viewing a pdf from within a browser window). [Edit: here's that link: http://forums.adobe.com/message/5055202#5055202 ]
Is there a way from an html page or from something within a PDF document (at the discretion of the document's author) to open a pdf in the acrobat reader window instead of in the browser, without asking each user to change their reader settings? [Edit: I ended up asking this question in the same post listed above]

Once the instance of Acrobat or Reader containing a password-protected PDF file has been closed, you can't avoid having to re-enter the password. If the links don't target a new tab or window, then the browser will unload the plugin - and aside from changing all the link targets, you can't prevent that.

I should be getting output just like below : the rest of it should not be repeating.
What am I doing wrong that , ItemInfo node(in output) is repeating ?How can I correct it ?
<ns0:TargetData
xmlns:ns0="http://P1.Schema2">
<ItemInfo>
    <ItemNumber>ABX-9302</ItemNumber>
    <SubItemInfo>
      <SubItemPart>aaaa</SubItemPart>
    </SubItemInfo>
</ItemInfo>
<ItemInfo>
    <ItemNumber>ABA-1307</ItemNumber>
    <SubItemInfo>
      <SubItemPart>1307-1981</SubItemPart>
    </SubItemInfo>
    <SubItemInfo>
      <SubItemPart>1307-1982</SubItemPart>
    </SubItemInfo>
    <SubItemInfo>
      <SubItemPart>1307-1983</SubItemPart>
    </SubItemInfo>
</ItemInfo>

Display group by field value only once for each group

I have a table with following fields:
TicketNo (varchar2)
TName (varchar2)
DateIssue (Date/Time)
I wanto retrieve result in the following form:
DateIssue TName TicketNo
01-oct-2006 ABC 123-7733
DEF 545-54454
GHI 254-4545
02-oct-2006 JKL 454-7897
MNO 444-7878
TName and TicketNos must be grouped by DateIssue. Since "Group By" clause uses agregate functions only, therefore this type of query will not run:
SQL> Select DateIssue,TName,TicketNo from Table1 group by DateIssue order by DateIssue;
How to display the above given result?

SQL> select * from tickets;
TICKETNO   TNAME      DATEISSUE
121-565    abc        04-FEB-07
454-hj     def        04-FEB-07
4545-856   gftr       03-FEB-07
fg45-856   gth        03-FEB-07
SQL> select decode(row_number() over(partition by to_date(dateissue) order by ticketno),1,dateissue) dateissue
2         ,tname,ticketno
3 from tickets;
DATEISSUE TNAME      TICKETNO
03-FEB-07 gftr       4545-856
          gth        fg45-856
04-FEB-07 abc        121-565
          def        454-hj
