XML PIVOT QUERY QUESTIONS

I'm new to PIVOT queries. I was making reference to the discussion that follows, but ran into a problem. https://forums.Oracle.com/message/9393302

When I added the XML to format data, I started to have NULL values rather than what I was looking for.

WITH (AS PIVOT_DATA)

SELECT * FROM)

SELECT THE REGION, FCST_PERIOD, PRIME_PART, FINAL_FORECAST

OF XYZ WHERE FCST_PERIOD > = last_day (trunc (sysdate)) + 1 and FCST_PERIOD < = last_day (add_months(sysdate,12)) AND PRIME_PART IN ('BLAH')

)

PIVOT XML (SUM (FINAL_FORECAST) FOR FCST_PERIOD IN (SELECT DISTINCT FCST_PERIOD OF XYZ))

)

SELECT PRIME_PART, REGION,

EXTRACTVALUE(FCST_PERIOD_XML,'/PIVOTSET/ITEM[1]/COLUMN[2]') FCST_PERIOD1,

EXTRACTVALUE(FCST_PERIOD_XML,'/PIVOTSET/ITEM[2]/COLUMN[2]') FCST_PERIOD2,

EXTRACTVALUE(FCST_PERIOD_XML,'/PIVOTSET/ITEM[3]/COLUMN[2]') FCST_PERIOD3

OF PIVOT_DATA;

RESULTS IN:

PRIME_PART	REGION	FCST_PERIOD1	FCST_PERIOD2	FCST_PERIOD3
BLA	MIDWEST	(NULL)	(NULL)	(NULL)
BLA	WEST-NV	(NULL)	(NULL)	(NULL)
BLA	SOUTH-EAST	(NULL)	(NULL)	(NULL)
BLA	WEST-CA	(NULL)	(NULL)	(NULL)
BLA	SOUTHWEST	(NULL)	(NULL)	(NULL)
BLA	EAST	(NULL)	(NULL)	(NULL)

The second part of my question is how would I do a group when you use a pivot query. When I finished, I've has several parts and would like to group by REGION.

Thank you!

Names of elements and attributes in XML are case-sensitive.

Try with:

EXTRACTVALUE (FCST_PERIOD_XML, ' / PivotSet/item [1] /column [2]') FCST_PERIOD1

There is also a good chance that EXTRACTVALUE is frowned upon in your version. Instead, use XMLQuery or XMLTable.

That being said, using XML PIVOT just to grind it later into a number known columns is pretty useless.

The same can be achieved much more efficiently with regular PIVOT operator (and if necessary analytical function).

Post some examples of data in the table of your database and your final result expected to get useful assistance.

pivot query question

I have a query in Oracle 11:

 select to_char(da,'DY-DD') days
from (
        select rownum -1 + to_date('2012-10-15','yyyy-mm-dd') da, l
        from   (select level l
                from   dual  connect by level <= to_date('2012-10-21','yyyy-mm-dd') - to_date('2012-10-15','yyyy-mm-dd')+1)
        order by 1)

Result

"DAYS"
MON-15
TUE-16
WED-17
THU-18
FRI-19
SAT-20
SUN-21

What I need which is present in a row instead of a column:

 MON-15  TUE-16  WED-17  THU-18  FRI-19  SAT-20  SUN-21

This should be done with pivot requests? Any suggestion please!
Thanks in advance.

I need in 7 different columns.
Oracle version is 11.2.0.1.0. Could you give an example of how to do this with pivot query?

Here's one way:

WITH     all_days     AS
(
     SELECT     LEVEL  AS n
     ,     TO_CHAR ( TO_DATE ('2012-10-15','yyyy-mm-dd') + LEVEL - 1
               , 'DY-DD'
               )     AS dy_dd
     FROM    dual
     CONNECT BY  LEVEL <= TO_DATE ('2012-10-21','yyyy-mm-dd') + 1
                        - TO_DATE ('2012-10-15','yyyy-mm-dd')
)
SELECT     *
FROM     all_days
PIVOT     ( MIN (dy_dd)
       FOR  n  IN (  1  AS col_1
                      ,  2  AS col_2
                      ,  3  AS col_3
                      ,  4  AS col_4
                      ,  5  AS col_5
                      ,  6  AS col_6
                      ,  7  AS col_7
                      ,  8  AS col_8
                      ,  9  AS col_9
                      , 10  AS col_10
               )
      )
;

This always displays exactly 10 columns.
If the subquery produces less than 10 dates, then the last columns will be NULL.
If the subquery produces more than 10 dates, will be not shown the 11th (and later versions).

There is nothing special about the number 10; You can have any number of columns you want. The number of columns and their names is fixed when you write the query, regardless of what is in the subquery. If you want a dynamic number of columns, or names derived from data, see {message identifier: = 3527823}

Pivot query

Hi all

I wrote a pivot query but it is not giving me the expected output.

with test as
( select 'outgoing' type_of_call, 'local' sub_type_call, '1sec' pulse, 0.3 call_charge from dual union all
  select 'outgoing' type_of_call, 'STD' sub_type_call, '2sec' pulse, 1.5 call_charge from dual union all
  select 'outgoing' type_of_call, 'ISD' sub_type_call, '1sec' pulse, 4 call_charge from dual union all
  select 'SMS' type_of_call, 'local' sub_type_call, '1' pulse, 0.5 call_charge from dual union all
  select 'SMS' type_of_call, 'STD' sub_type_call, '1' pulse, 1 call_charge from dual union all
  select 'SMS' type_of_call, 'ISD' sub_type_call, '1' pulse, 3 call_charge from dual
)
select * from test
pivot(count(type_of_call) for (sub_type_call) in ('local','STD','ISD') );

O/P should look like
Type_of_call         pulse_local     charge_local  Pulse_STD   charge_STD  pulse_ISD  charge_isd
outgoing             1sec            0.3            2sec        1.5         1sec        4
SMS                  1               0.5            1           1           1           3

Is there something that I am missing in the query?

Thank you

This sounds like a job for LISTAGG:

SELECT NULL AS link

label

LISTAGG (comp_name, ',')

THE Group (ORDER BY ComputerName) AS value1

OF test1

GROUP BY label

;

If you would care to post CREATE TABLE and INSERT statements for your sample data, then I could test it.

Are you sure that the results you posted are what you want from data provided?

Is of the order of the elements in a significant list? In other words, when you say you want to get the results:

COMP1, COMP2

you'd be just as happy with

ORDI1, COMP2

? If the order is important, explains what this order.

Getting counties and divide by the sum in a single Pivot query

Hello

I have a pivot query that gives counties of all codes. I have also separated the number with the total in the same query.

e.g

  col1          col2                   col3
error_1       05-Jun-2012       parts
error_1      05_june_2012     parts
error_1      04_june_2012     consumables
error_2      04_june_2012     consumables
error_3      03_june_2012     parts
.
.
.

Now, the output should have the counts / divided into sum multiplied by 100. Basically, the percentage.

output will be something like

error                     June-2012                                 May-2012                              Feb-2012 ....      headers
error_1                    60%                                          0 %                                         0%
error_2                    20%                                          0                                             0%
error_3                    20%                                           0%                                         0%

Any suggestions please?

Hierarchy XML query question

I have a table in the form of:

A, B AND C 1 2 3
B 4 5 6 D
A C 7 8 9

I want my XML in the form
< name FOO = 'A' >
< BAR name = "B" >
< name ZEE 'C' = >
< x >/< x > 1
< Y > 2 / < y >
< Z > 3 < /z >
< / ZEE >
< name ZEE = "D >.
< x > 4 / < x >
< Y > 5 / < y >
< Z > 6 / < z >
< / ZEE >
< / BAR >
< BAR name = "C" >
< name ZEE = 'A' >
< x > 7 / < x >
< Y > 8 / < y >
< Z > 9 / < z >
< / ZEE >
< / BAR >
< / FOO >

Is such a thing possible via SQL directly or I have to do a sort of XSL transformation? Can someone tell me something that speaks of how this is done?

It should do so using bys group successive and enveloping the xml of lower level with parent elements.

with

select akdomain, datacenter, akresource,
       xmlagg(

-- Consolidate the resources by domain, datacenter.

PTC connector query questions
I develop a connector and had some questions about the presentation of the petition. I tried to read the documentation and help, but saw no reference to these issues. I know that some of these things may not still have public API, but any help would be appreciated.

(1) is it possible to disable the entry blank for a ComboBox and set one of the values? I am referring to when you click on the button '+' on a query and selecting a comboBox field. I tried the 'enableEmptyEntry' attribute but could do not seem to work.

(2) is there a way to prevent several lines for the same domain? I'm trying to match a web interface that allows values separated by commas in certain areas and not others. Trying to decipher the intent of the user if they use multiple lines for the same field becomes confused.

(3) is there a way to disable 'Match All' or 'match any '?

Thank you
After further review, the removal of the empty the box entry drop-down list on the query page is not possible.

One feature that we've added in the last release to support the case where the user needs to find records with a null or empty value for this combobox field. For example, finding bugs without test status. We have generic for all drop-down list boxes.

The 'enableEmptyEntry' attribute is intended to work with the attribute "emptyEntryValue" as a pair. The user can do something like this in def.xml:
enableEmptyEntry = 'true '.
"emptyEntryValue =""
Our framework poster in the drop-down list instead of empty or the default value .

We recorded a feature request for this for a future version. Currently, writer connector is not a way to customize our application page, including the MatchAll, MatchAny option.

Progressive, Question on the fields of dynamic/DocID/Query Question of profiling

This may seem like a newb question but someone has a logical division of the BOM designation DocID?
In the course, we are responsible to use DocID = 1 and DocID = 2, but when/why would you use DocID = 3 or higher?
Any help would be greatly appreciated with the portion of dynamic fields/query string of the progressive profiling course.
Thank you.

The DocID is a complete example. You can actually assign the query string to be what you want. I recently use cmpID for the campaign ID, where I spent to map identity of the campaign and then sent the URL to redirect dynamically the campaign ID field. In my case, we worked with 10 different docs or goods, so we had to actually 10 unique codes. In this case we would have, for example cmpID = 483h76d; cmpID = 9j872hd, etc, etc. If you want to learn more about how you can use the query string values, see this post: how Progressive E10 profiling using the component of cloud - scroll down to step 6 and you'll see how to set up dynamic rules using query strings.

Can someone advice how can this be corrected?

I reworked the code to use the scott. EMP table.

I got the SQL Select function resulting and he ran in SQL Developer.

Syntax 1

You must remove aliases for tables of the PIVOT() section.

line 16 and 17 should be

SUM (SAL)

FOR USE IN (...)

Syntax 2

Line 11: you add comma and space (2 characters)

Line 17: you remove only 1 tank

Syntax 3 (problem semi)

Although the APEX works with it, I would abandon the semicolon (;) to the end.

To name the columns, you must create a function that returns the name of the report column.

Again, this must match the columns listed in the SELECT part

reminder of my warning:

Using a "SELECT *" and lack of "ORDER BY" in your cursor will cause you problems. (maybe not now, but it will.)

Query does not work on my iPad (was: media query question)

I am a site for mobile/tablet/Office of coding and while my office and the iphone respond to the CSS, my ipad does not work. The changes that I do take the tablet in dreamweaver, but when they go live the ipad does not. Of course, my media query must be incorrect, but I can't understand the question. Any help is very appreciated.

Thank you.

Yes. It is inevitable because smart phones are getting bigger while tablets are smaller & more. He's always going to be some crossover. Think of it this way, when a Tablet is behaving as a mobile device, he takes over the mobile network. When the shelf behaves more like a desktop computer, you need the layout of office.

Similarly, a great smartphone in landscape mode is likely to resemble the layout of your tablet.

See the FluidGrid example below:

http://ALT-Web.com/FluidGrid/Fluid2.html

Office = 4-col layout

Tablet = 2-col layout

Mobile = 1-col layout

For purposes of illustration, I added a thick border of gold at the disposal of the Tablet only.

/ * Tablet Layout: 481px to 768px. Inherits the styles of: Mobile layout. */

@media only screen and (min-width: 481px) and (max-width: 768px) {}

.gridContainer {width: 92%; border: 16px solid gold}

Why XML XML Simple query on Table Eval does not work?

I have a request that a simple select on a binary xml table on 11.2.0.1:

Unfortunately, the query returns with a null value instead of; RickBlanchard9963

Must be something obvious missing here...
Any help is appreciated.

Kind regards
Rick Blanchard

The sample document contains evalId = "RickBlanchard9963", not "RickBlanchard9972" but it's probably a typo?

The real problem is that you are missing from the default namespace declaration in XMLQuery.

Dynamic form: XML Data Import Question (I'm almost there..)

Niall was very useful gettig me at this point. Thank you very much!
I did all my updates and changes that have been suggested in the following form:
https://Acrobat.com/#d=t1uvlNlj4Yrh7zxtpbJiRg
My question is, when I import the XML data file, only a few of the shows of information upward?
Thought of back in all it took to get to this day, I don't know if I should not be only to count my blessings to be where I am? But, if someone (and knowing Niall is probably reading this - but I was too embarrassed to ask for more help), could help to tell me what I should do, I think it will be the last time I have to ask for help... at least on this form.

Thank you!!!

Hi Rob,

In this case you don't need a data connection.

If you select a field and go to object > link tab, you will see a drop-down list to specify the data binding for this field. Currently it is set to 'None', which means that the field data will not be exported. Similarly, if you had an XML file with data, it would not be imported into the field.

Here is a screenshot of LC Designer ES2, which is slightly different for earlier versions, but the basic process is the same.

Go through each field and change 'No data binding' / 'None' to 'Use the name' / 'Normal '.

Then when you are proposing and import, data populates the fields.

Hope that helps,

Niall

BI Publisher data model / query question
Hello

I'm designing a report of BI Publisher where I need to show negative numbers in red. I'm perfectly fine with the help of the conditional formatting to do this (just using the default value is conditional formatting in the add-in in MS Word, that generates code like this:)

<? If: number(Cost_-_MTD) < 0? > <? attribute@InContext:color;' Red '? > <? end if? >

BUT...

I have columns returning who sometimes have a NULL value in them, and when they have the value NULL, it causes the foregoing to the pipe upwards. So I thought, 'I'll just add IfNull() in queries defined in the model data, and who will take care of the problem... "

that works - a little. Now, my problem is if I have to go back and change the query for some reason, I get an error "query cannot be parsed, please modify the query manually. I really don't want to do that, I wish that other developers do NOT have to manually change the queries.

So my question is - is it possible to add in the IfNull() directly in the query designer, so it should not be changed manually from that moment?

p.s. using IfNull OBIEE server as our data source.

Thanks in advance,
Scott
I don't think there is a way to add the ifnull condition in the query designer. So, you will need to manually change the query...

In your model so you can add additional control like this:
<0?>...

Thank you!

Still not sure why nvl shouldn't meet your needs:

  from emp pivot (sum (sal)

Pivot query problem

All (running 11.2 OEL on 5),
I'm fighting figuring how to get the result I want to with the following data:

CREATE TABLE REGION_LOOKUP 
   (     REGION_ID NUMBER NOT NULL ENABLE, 
     REGION VARCHAR2(5) NOT NULL ENABLE, 
     PRIMARY KEY ("REGION_ID") ENABLE
   )
/ 
CREATE TABLE IND_REVENUE 
   (     ID NUMBER, 
     IND_REV_DATE VARCHAR2(30), 
     IND_REVENUE NUMBER, 
     REGION_ID NUMBER, 
     CONSTRAINT IND_REVENUE_PK PRIMARY KEY (ID) ENABLE
   )
/
INSERT INTO REGION_LOOKUP (REGION_ID, REGION VALUES(1,'EMEA');
INSERT INTO REGION_LOOKUP (REGION_ID, REGION VALUES(2,'LAD');
INSERT INTO REGION_LOOKUP (REGION_ID, REGION VALUES(3,'APAC');
INSERT INTO REGION_LOOKUP (REGION_ID, REGION VALUES(4,'NAS');
INSERT INTO REGION_LOOKUP (REGION_ID, REGION VALUES(5,'JAPAN');
/
INSERT INTO IND_REVENUE VALUES(1,'10-Jun',73.10,4);
INSERT INTO IND_REVENUE VALUES(2,'10-Jul',49.30,4);
INSERT INTO IND_REVENUE VALUES(3,'10-Jun',3.20,2);
INSERT INTO IND_REVENUE VALUES(4,'10-Jul',0.30,2);
INSERT INTO IND_REVENUE VALUES(5,'10-Jun',28.60,3);
INSERT INTO IND_REVENUE VALUES(6,'10-Jul',12.40,3);
INSERT INTO IND_REVENUE VALUES(7,'10-Jun',64.00,1);
INSERT INTO IND_REVENUE VALUES(8,'10-Jul',19.80,1);
INSERT INTO IND_REVENUE VALUES(9,'10-Jun',6.60,5);
INSERT INTO IND_REVENUE VALUES(10,'10-Jul',4.70,5);
/

Here's what I would get. The column date 10 - Jun 10 - Jul is 'dynamic', and there will be a new column each month.

Region     10-Jun     10-Jul      Total
APAC      $28.6     $12.4      $41.0
EMEA      $64.0     $19.8      $83.8     
JAPAN       $6.6      $4.7      $11.3
LAD       $3.2      $0.3       $3.5
NAS      $73.1     $49.3     $122.4
Total     $175.5     $86.5     $262.0

I think something like that (I'm stuck) but of course, this does not at all and is also hardcoded regarding columns.

select rn, 10-Jun, 10-Jul, (10-Jun + 10-Jul) as Total from
(select      RL.REGION_NAME as rn, RL.REGION as re, IR.IND_REVENUE as rev
 from      REGION_LOOKUP RL,
      IND_REVENUE IR where IR.region_id = RN.region_id)
pivot (SUM(rev) for rn in
('10-Jun' as 10-Jun,
'10-Jul' as 10-Jul))

All great ideas?

See you soon,.
Andy

Fixed the instructions insert, sorry about that. Copy and paste before the coffee is not good.

Hi, Andy.

A Tael says:
A nice solution,

Thanks, but what solution do you mean? There were at least 4 different solutions on this page.

but is there a way to avoid the queue to a file?

Do you mean the dynamic SQL solution? Yes, the coil is just a way to make the dynamic SQL statements.
In SQL * more you can write the variable part of the query to a substitution variable (see below).
In PL/SQL, you can assemble a select in VARCHAR2 variable.

PROMPT     ==========  2. Dynamic Pivot using Substitution Variable  ==========

--     *****  Preliminary Query:  *****

COLUMN     sql_txt_col     NEW_VALUE     sql_txt

WITH     all_jobs     AS
(
     SELECT DISTINCT
          job
     ,     DENSE_RANK () OVER (ORDER BY job)     AS r_num
     FROM     scott.emp
)
SELECT     SYS_CONNECT_BY_PATH ( job || '''     THEN 1 END) AS '
                      || job
                      || '_CNT'
                      || CHR (10)               -- Newline, for legibility only
                   , ', COUNT (CASE WHEN job = '''     -- Delimiter, goes before each entry
                   )                                       AS sql_txt_col
FROM     all_jobs
WHERE     CONNECT_BY_ISLEAF     = 1
START WITH     r_num = 1
CONNECT BY     r_num = PRIOR r_num + 1
;

--     *****  Main Query  *****

SELECT     deptno
&sql_txt     -- Ends with newline, so occupy that line
FROM     scott.emp
GROUP BY     deptno
ORDER BY     deptno
;

/*
EXPLANATION:

Using a substitution variable is very similar to using a script.
The main difference is that the output of the preliminary query has to
go into one row.  This is done with SYS_CONNECT_BY_PATH, and getting
that requires that the jobs be numbered with consecutive integers, 1, 2, 3, ...
which we get from DENSE_RANK.

The NEWLINE character was added just to make the output line easier
to read during debugging.
