XPath max function

Hi all,
I'm a beginner working with XPath expressions.
I have a xml document 'test.xml' with the following contents.
<?xml version="1.0" encoding="UTF-8"?>

I use the code to obtain information about xml.
SELECT extractValue(value(d), '/ICRI/NombreRecurso', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') NOMBRERECURSO,
       extractValue(value(d), '/ICRI/TipoRecurso', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') TIPORECURSO,

        extractValue(value(d), '/ICRI/Descripcion', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') DESCRIPCION,
        extractValue(value(d), '/ICRI/Modificaciones/Modificacion/Secuencia', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') SECUENCIA
FROM RESOURCE_VIEW r, table(xmlsequence(extract(r.res, '/r:Resource/r:Contents/i:ICRI', 'xmlns:r="http://xmlns.oracle.com/xdb/XDBResource.xsd" xmlns:i="http://www.orswegimoarmada.es/ORSWE/ICRI"'))) d
WHERE r.any_path='test.xml'But the element Secuencia has several values and I only need to obtain the max of this values. I think, XPath max function can resolve this issue, but I don't know how do I do this?. Is it possible?
Thanks in advance,
David.

Well, I am desperate :-(((
I am trying to extend the early query, now, r.any_path must be obtained from another table that it is another registered schema also.
The folowing is a piece of this query:
SELECT
extractValue(value(di), '/ICRI/NombreRecurso', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') NOMBRERECURSO,
extractValue(value(di), '/ICRI/TipoRecurso', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') TIPORECURSO,
extractValue(value(di), '/ICRI/VersionRecurso', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') VERSIONRECURSO,
extractValue(value(di), '/ICRI/Descripcion', 'xmlns="http://www.orswegimoarmada.es/ORSWE/ICRI"') DESCRIPCION
FROM RESOURCE_VIEW r,
     table(xmlsequence(extract(r.res, '/r:Resource/r:Contents/i:ICRI', 'xmlns:r="http://xmlns.oracle.com/xdb/XDBResource.xsd" xmlns:i="http://www.orswegimoarmada.es/ORSWE/ICRI"'))) di
WHERE
    r.any_path IN
    (select extractValue(value(t), '/InfoEntradaGeneral/EnlaceICRI', 'xmlns="http://www.orswegimoarmada.es/ORSWE/PlantillaProyecto')
     FROM PLANTILLAPROYECTO p, table(xmlsequence(extract(p.object_value, '/PlantillaProyecto/Proceso/Pasos/Paso[@IdPaso="0"]/Actividades/Actividad[@IdActividad="1"]/EntradasActividad/EntradasGenerales/InfoEntradaGeneral'))) t
     WHERE existsNode(p.object_value, '/PlantillaProyecto/DetallesProyecto[NombreProyecto="Prueba"]')=1);Now, Oracle only shows me a register when the query must be three.
The query
select extractValue(value(t), '/InfoEntradaGeneral/EnlaceICRI', 'xmlns="http://www.orswegimoarmada.es/ORSWE/PlantillaProyecto')
FROM PLANTILLAPROYECTO p, table(xmlsequence(extract(p.object_value, '/PlantillaProyecto/Proceso/Pasos/Paso[@IdPaso="0"]/Actividades/Actividad[@IdActividad="1"]/EntradasActividad/EntradasGenerales/InfoEntradaGeneral'))) t
WHERE existsNode(p.object_value, '/PlantillaProyecto/DetallesProyecto[NombreProyecto="Prueba"]')=1);returns several values, for instance:
1. test.xml
2. test1.xml
3. test2.xml
Why does not it work?. I suppose that the query is correct.
I try the same with relational tables and it works fine.
Query SELECT B.COLUMN2 FROM B WHERE B.COLUMN1 IN (SELECT COLUMN1 FROM A returns several values from A and shows the right values from B.
Please, Could someone to help me?
Thanks in advance,
David.

How to Avoid Errors in Max Function When Data Contains Blank Cells

I have a column with duration values. However, it also contains some blank cells. These "blank cells" have formulas in them, but as the cells they reference too are blank the formula doesn't produce a result.>/p>
I want to get the max value from this column. When I simply do =MAX(column-name) I get an error, presumably because some of the cells are blank. This table is going to be highly dynamic, so I don't want to limit the range of the MAX() function to only those cells with values.
So does anyone know a solution for this, please? If I was some how able to create a formula which returned the range of cells with actual values, then I could use that in the MAX() function. Or, if I could somehow tell the MAX() function to ignore blank cells, but I'm not sure either of these are possible.
Thanks,
Nic

I don't see a problem with "blank" (null string) cells mixed with duration cells. MAX works fine with this mix of cells. But if the "blank" cells are numbers, not text, that gives an error.
A formula always produces a result. A formula cannot result in a blank cell. The closest you can get to "blank" is a null string (the result of two quotes next to each other with nothing between them) . So the question is, what is the result that you are calling "blank"?

MAX function

Hi Everyone,
Am aware of the following flavors of MAX function
1) choose MAX from the folders/fields list (selected items tab)
2) create calculation using: MAX keep dense
3) create calculation using: MAX analytic function
questions, pls:
===========
a) with MAX regular, MAX keep dense, MAX - analytic function
is it necessary to sort it using tools/sort - choose fields to sort by?
or does the data get sorted due to the ORDER BY clause in MAX used in a calculation
b) how to understand the diff. bet. MAX keep dense and MAX - analytic function
1) i understand that analytic functions are applied after detail row processing
does MAX keep dense calculation happen during detail row processing?
2) how did you know to advise when to use MAX keep dense, and when to use MAX - analytic function?
tx for your ideas and assistance, sandra

Hi,
a) with MAX regular, MAX keep dense, MAX - analytic function is it necessary to sort it using tools/sort - choose fields to sort by? or does the data get sorted due to the ORDER BY clause in MAX used in a calculationIt is only necessary to use a sort if you want to have the rows returned in a specific order. The order by in the max calculation defines the maximum within the group or window. It may affect the order the rows are returned, but if it does this is not guaranteed and you should use a sort on the main query.
b) how to understand the diff. bet. MAX keep dense and MAX - analytic function
1) i understand that analytic functions are applied after detail row processing does MAX keep dense calculation happen during detail row processing?Yes
2) how did you know to advise when to use MAX keep dense, and when to use MAX - analytic function?In general, if you want the result on a single row, so you have one row for each group then you should use the aggregate max. If you want to use the same max on all the rows in the window (defined by the partition) then use the analytic max.

Using max function in PL/SQL

VERY URGENT...
Am new to oracle...
I've written a package that display gif images in form of histogram/bar chart. using html,
I need to use max function to display values proportionately.
please help. i need to complete this assignment by 2/9/00 by 10.00 am at the latest. I've half written a function but I don't know if there's a simpler way fo doing this. html enabled

First of all Thanks to all gentlemen who replied ..many thanks ...
Tried the ROW_NUMBER() option but still it is taking time...have given output for the query and tkprof results as well. Even when it doesn't fetch any record ( this is a valid cased because the input header id doesn't have any workflow request submitted & hence no entry in the wf_items table)..then also see the time it has taken.
Looked at the RANK & DENSE_RANK options which were suggested..but it is still taking time..
Any further suggestions or ideas as to how this could be resolved..
SELECT 'Y', 'Y', ITEM_KEY
FROM
( SELECT ITEM_KEY, ROW_NUMBER() OVER(ORDER BY BEGIN_DATE DESC) RN FROM
WF_ITEMS WHERE ITEM_TYPE = 'xxxxzzzz' AND ROOT_ACTIVITY = 'START_REQUESTS'
AND SUBSTR(ITEM_KEY,1,INSTR(ITEM_KEY,'-') - 1) = :B1
) T WHERE RN <= 1

Use of MAX function

Hi,
I am using parent-child hierarchy and in my reports I want to show Max(hierarchy_level). When I use the function MAX directly in the report it works fine in every way. But I want to have this kind of column in the BI Server presentation catalog so the user does not need to add MAX in Analysis/Answers (this is 11g). Normally this would imply a Max(hierarchy_level) as a logical function, but in the BI Server it is not allowed with MAX function in the logical function so it does not work.
The hierarchy level is just a column from a dimension table and creating it as a fact column is not a very good solution. I also tried to solve this in many different ways, but only the MAX funtion in Analysis/Answers allways give the correct result. Used in combination with other dimensions etc. I want the exact same behaviour as I get when using MAX in analysis.
Any good ideas to solve this? Is there another function in the BI Server that works the same way as MAX ?

Very often, about a primary key, see for example our italian accounting application (our VAT invoices:fatture IVA) ), where the holes might be a problem.
Yes Rosario, of course I know that, and that's why I said "in this scenario" : if primary key is the only purpose, I don't think holes could be a problem.
Buona giornata anche a te.

Jar-file for XPath extension functions

Hi all,
can anyone tell me which jar-file contains the class for the following xpath extension function / method:

Thanks in advance, Ingo

When you go to :

Use of MAX function in Query Designer

Dear all,
i want to create a report that gives ONE line per period that holds the MAX of several lines per period. So NO addition of the KF but just one line item.
I tried to use the MAX function and/or MAX drop-down boxes via properties on KF,
but they all provide the wrong result (mostly the MAX after summaction of the KF).
Any ideas ??
Greetz,
Herman

Hi Herman
Please check the KF infoobject property which might have been set to Summation. You need to change the property of the KF to MAX if you wish to have MAX value.
Hope this might be helpful to you
Thanks

How to use MAX() function with date field

Hi Frzz,
I have created a Graphical calculation view in which i have multiple records for each employee with different dates. But my requirement is to take the records which have maximum date.
I have converted the date into Integer and applied the MAX() function. But still am getting multiple records.
Is there is any other way we can achieve this requirement in Graphical Calculation view?? Your suggestion will really help me.
Thank you.
Krishna.

Hmm... what have you tried out so far?
Look, I took the effort and created a little example, just for you
Assume we have a table that contains the logon dates of users.
Every line contains the logon date and some info on the user.
Very much like a not-normalized log file could look like.
Now, the output we want is: one line per user with the most current logon time.
Not too difficult:
1. Have a aggregation node that gives you the distinct user details - one line for every user:
2. Have another aggregation node that gives you the last (MAX) logon date per user:
Finally you do a 1:1 join on the USER_ID and map the result to the output.

Use COUNT or MAX functions inside of a query, and you have no data found

I'm writing a query with a COUNT and a MAX function.
    SELECT li.id
             , MAX(m.display_date)
            , COUNT(*)
     FROM li JOIN m ON (m.LIID=li.LIID)
    WHERE m.DISPLAY_DATE < SYSDATE - 7
    GROUP BY li.id;I would like to write a query that returns always a row foe each row in the table li.
If there are no records with the condition "WHERE m.DISPLAY_DATE < SYSDATE - 7", I would like to have a row with
- COUNT(*) = 0
- MAX(m.display_date) = TO_DATE('2010-06-08', 'YYYY-MM-DD'

Using Max Function in View Criteria

Hi
I am having a requirement where by i need to make use of max function in view criteria but not able to see any such option. Can someone please help me over it. Here is the requirement.
In table i will be having multiple rows for an employee and i need to pick latest row based on a column say request_id For e.g.
Emp RequestId
A 1
A 2
A 3
A 4
So if i pass the employee id i should get Row Number 4. In simple SQL language I want something like this
select * from emp where empid=A and requestid=( select max(requestid) from emp where empid=A)
Just wanted to know is there any approach that i can use to do all this as part of View Criteria or any other way.
Any help is appreciated!!!
Thanks
AJ

One way is this -
1)https://blogs.oracle.com/adf/entry/using_groovy_aggregate_functions_in (You might need to create a self-referencing VL for this , try if it works using a ViewAccessor too)
OR
Order by RequestId descending in your SQL for the VO if thats ok , then have the ViewCriteria for the EmpId and programmatically pickup the first row...

Problem with max function in air

Hello ,how are you,I write this query : [b]SELECT *, max(trackerId) FROM sessiontracker [/b]in
sqlite manager and it works ,but when I use it in Air application ,it send me back this error:
ReferenceError: Error #1056: Cannot create property max(trackerId) on
com.afarinesh.models.SessionTracke
,I guess that Actionscript 3 can not pars max function.
I appreciate your help

Hello,
AIR does support max function. Please see Page 1067 of the actionscript developer's guide, which can be download from http://help.adobe.com/en_US/as3/dev/as3_devguide.pdf. And I tried the max function in my AIR application: create a table, insert some records into the table, and use the "select *, max(column) from table". It works fine.
I noticed your error is the ReferenceError and related to some AS class. So I am not sure if you use any ORM tool. If so, the issue may be caused by the use of the tool. Please check the configuration and usage of the tool.
Thanks,
Yang

Max value without using max() function

Hi
Is there any way to get the max value from a table without using MAX() function
Thanks

well if you think about it i'm sure you'll find a solution
what does max(field) means, it simply is the value of the field where no other value of the same field that is > than this value exists.
consider the following :
table TAB(
fld NUMBER(5));
translate the logic and you'll have
select a.fld from TAB a where NOT EXISTS(select b.fld from TAB b where b.fld>a.fld) and rownum=1;
of course there are better ways i'm sure, you'll just have to figure'em out.
