Hello
I'm now in xml... I'm trying to generate XML from a ref_cursor... can someone tell me how I can achieve this?

Does this help start?

create or replace function my_func(ctr number)
return sys_refcursor
as
  l_cur sys_refcursor;
begin
  open l_cur for select * from all_objects where rownum <= ctr ;
  return l_cur;
end;
/

One way to use it is:

select xmltype(my_func(2)) from dual ;

Another way is:

declare
   hnd dbms_xmlgen.ctxhandle;
begin
   hnd := dbms_xmlgen.newcontext(my_func(2));
   dbms_xmlgen.setrowsettag(hnd, 'CURSOR');
   dbms_output.put_line(dbms_xmlgen.getxml(hnd));

B2B Gateway fails to generate data xml for 997
Hi all

I am faced with a particular problem with one of my test B2B case, where xml for 997 EDI X 12 file is not generated. The file EDI 997 is get picked up however it will fail to generate the request message. In the report so there will be no errors. When I click on the details link on the page of reports for the 997 message the message of application link is not active and does not redirect to the details of the application pop up message by clicking on it.

Could someone of you please think why this problem occurs... It worked perfectly in my case of dev...

Please also suggest if more details could be found in the log files of B2B.

Your real problem is configuration...

You must go to the Configuration under Administration tab and section of the page, set "notify functional Inbound" accused of reception and the "receipt functional managed automatically ' to 'true '. Otherwise the message from the Application does not get generated for your 997 s entering.

To remove data XML from XML using REGEXP_REPLACE tags
Hello

I try to use the SQL REGEXP_REPLACE function on a piece of XML, to remove the actual XML data from the weather. My ultimate goal is to end up with a list separated by commas to names of XML elements. In the first stage, I want to just pull all of the actual data.

I tested the following query, and it initially appeared to work:
```
SELECT REGEXP_REPLACE('&gt;THIS IS A TEST&lt;', 
                      '&gt;([[:alnum:]]\s|\S)*&lt;',
                      '&gt;&lt;' ) AS test_result
  FROM dual;
```
Unfortunately, when I applied it to a full XML string, it did not. Here is the query to test that I used:
```
SELECT REGEXP_REPLACE('&lt;ROW&gt;&lt;TEST_ELEMENT1&gt;123&lt;/TEST_ELEMENT1&gt;&lt;TEST_ELEMENT2&gt;THIS IS A TEST!&lt;/TEST_ELEMENT2&gt;&lt;/ROW&gt;',
                      '&gt;([[:alnum:]]\s|\S)*&lt;',
                      '&gt;&lt;') AS test_result
  FROM dual;
```
I found myself with the following result:

* & lt; LINE & gt; & lt; / LINE & gt; *

What I was trying to a:

* & lt; LINE & gt; & lt; TEST_ELEMENT1 & gt; & lt; / TEST_ELEMENT1 & gt; & lt; TEST_ELEMENT2 & gt; & lt; / TEST_ELEMENT2 & gt; & lt; / LINE & gt; *

If you are reading this and you are a Posix regular expression guru, could you let me know exactly where I am going wrong? Regular expressions are not my strong point, but I would better go home.

Merge two files of system-jazn-"Data.xml"
Hello

I have a system-jazn-"Data.xml" from Apps BI 7.9.6.4 sized * 1291 KB * (having financial, HR, EAM Analytics) Note: a new installation and no changes have been made in safety.

Now for EAM Analytics, there is a bug and all application roles are not present in the policy store and apply a patch Patch 16321623 which just States copy the new file system-jazn-"Data.xml" to the location of fmwconfig (see ) doc 1548988.1 )
Problem is that the size of the system-jazn-"Data.xml" is * 342 kb.*

Looks like both of these system-jazn-"Data.xml" should be merged. (don't know, maybe this 342KO file contains all application roles)
Need advice here... as for what I'd do here. ?

Thank you
Ashish
See that there is no problem if you replace, just take the backup or rename the existing _old and copy a new. Even when I installed the OBIA on windows machine on top of some OBIEE dummy to generate the folders (biapps) of informatica, dac, RPD, catalogue files metadata then afterwards I got the file from the file 800ko and according to the guidelines of the oracle, I need to replace the one that is generated with OLIVIER on top on OBIEE which is only 320 kb file I simply replaced it na not thorw errors/problems until now. So I m confident enough to replace the file.

See this link http://docs.oracle.com/cd/E20490_01/bia.7963/e19038/windows_ic.htm#BABDCEGC paragraph 4.17 applying the security policy of the Oracle BI Applications to the BI domain

If your BI EE deployed with the Oracle's Applications of BI system is different from the BI EE system used to install some Applications of BI from Oracle, you must apply to the security policy of the domain of BI on BI EE system deployed by following the steps below.

If your BI EE deployed with the Oracle's Applications of BI system is the same as the BI EE system used to install some Applications of BI of Oracle, then the installer of Oracle's Applications of BI performs this configuration automatically.

To apply the security policy of the Oracle BI Applications to the BI domain:

Note: Machine is the machine system. B is the deployment machine.

Stop all processes in the system of BI EE. More precisely:

the Administration Server

+ (if there is a cluster) all managed servers in the cluster bi_cluster +.

all processes managed opmn

On computer B, save and rename the existing DOMAIN_HOME/config/fmwconfig/system-jazn-data.xml.

For example, if the root folder of BI EE is named OracleBIEE11g, then the folder location of the field (on Windows) can be C:\OracleBIEE11g\user_projects\domains\bifoundation_domain\config\fmwconfig.

Copy the jazn file Applications of BI of Oracle machine machine B to DOMAIN_HOME/config/fmwconfig A ORACLE_HOME/biapps/admin/provisioning/system-jazn-data.xml.

Start all processes in the BI EE system for security of Oracle's Applications of BI policy take effect. More precisely:

the Administration Server

+ (if there is a cluster) all managed servers in the cluster bi_cluster +.

all processes managed opmn

Hi, Fateh

One possible way is to use the XML features to create your XML file.
Using XML, you can make the IMAGES as a subquery XMLAGG rather than join at the table of the image.

Here is an example of the use of schema SCOTT:

SQL> select xmlelement(
  2            "ROWSET"
  3          , xmlagg(
  4               xmlelement(
  5                  "ROW"
  6                , xmlforest(
  7                     d.deptno as "ID"
  8                   , d.dname as "NAME"
  9                   , (
 10                        select xmlagg(
 11                                  xmlelement(
 12                                     "ImgUrl"
 13                                   , 'http://the.server.com/'||e.empno
 14                                  )
 15                                  order by e.empno
 16                               )
 17                          from scott.emp e
 18                         where e.deptno = d.deptno
 19                     ) as "Images"
 20                  )
 21               )

For a Web service you don't need to print the XML that is returned by the Web service.

I do not know APEX, so I don't know if APEX supports exposing an already built piece of XML, rather than expose a query result.
But my guess is that it should do very well if you ask an XMLTYPE data type (i.e. - to use the first of my examples, and not automatically printed.)

If you do not have APEX to do it this way, then I suggest that you try asking in the APEX forum rather than the SQL forum ;-)

Generate particular XML data

Hello

I need to generate this XML:

<? XML version = "1.0" encoding = "utf-8"? >
< message >
< pippo id = "30" content = "AMALI" / >
< id pluto = "14" content = "BBBBBBBBBBBBB" / >
< receptacle duckling = datetime 'CCC' = "' 10/10 / 2010:11:11:11 ' status ="0"/ >"
< / messages >

In this table, only lines with INDICATOR = 0:

CREATE TABLE TOPOLINO
(
NAME VARCHAR2 (20 BYTE),
IDENTIFICATION NUMBER NOT NULL,
DATE_TIME DATE,
CONTENT_MEX CLOB,
INDICATOR NUMBER
)

INDICATOR OF CONTENT DATE_TIME NAME ID ID2
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Pippo | 30. || ABDELLAH | || 0
Pluto | 14. || BBBBBBBBBBBBB | || 0
Duckling | || CCC | || 10/10 / 2010:11:11:11 | 0
Minni | 35. || KKKKKKKKKKKK | || 1

I'm doing some tests with XMLelements, XMLattributes, XMLconcat but not corrected its results.

Thank you very much.

Best regards.

With SQL/XML functions, an element name can be dynamic, but it is not directly possible with the attributes.
Thus, in the query below, I had to hard-code the attribute name "duckling":

select xmlelement("messages",
         xmlagg(
           case when id is not null then
             xmlelement(evalname(name),
               xmlattributes( id as "id",
                              to_char(content_mex) as "content" )
             )
           else
             xmlelement("receptacle",
               xmlattributes( id2 as "Paperino",
                              to_char(date_time, 'DD/MM/YYYY HH24:MI:SS') as "datetime",
                              0 as "status" )
             )
           end
         )
       )
from topolino
where flag = 0
;

With XQuery, however, you can generate any expression attribute name:

with t as (
  select xmltype(
           cursor(
             select name, id, id2, to_char(date_time,'DD/MM/YYYY HH24:MI:SS') date_time, content_mex
             from topolino
             where flag = 0
           )
         ) as doc
  from dual
)
select xmlquery(
'
 {
  for $i in /ROWSET/ROW
  return
    if ($i/ID) then
      element {$i/NAME} { attribute id {$i/ID},
                          attribute content {$i/CONTENT_MEX} }
    else
      element receptacle { attribute {$i/NAME} {$i/ID2},
                           attribute datetime {$i/DATE_TIME},
                           attribute status {0} }
 }
 '
 passing t.doc
 returning content
)
from t

Please can someone offer any assistance...?

Thanks for looking...

Hello

Your problem may be:
AND fu.description =: p_raisedby

If p_raisedby is null your query returns no data.

You need:
AND fu.description = nvl(:p_raisedby,fu.description)

SQL to generate the intervals from date of 6 months each, between two date ranges
Hi all

I looked in the forums, if someone uses CREATE_CHUNKS_BY_SQL for dates, but no luck.
I want to update a table using pieces of dates.
I need to generate date ranges to divide them by pieces.

I have a table where I know that max (sales_date) and min (sales_date).
Lets say max (sales_date): min (sales_date) 01/01/2008: 31/10/2010

I want to break in intervals of 6 months (180 days) as below:
```
chunk_id     start_date     end_date
--------     ----------     --------
  1          01/01/2008     06/30/2008
  2          01/07/2008     12/31/2008
  3          01/01/2009     06/30/2009
  4          01/07/2009     12/31/2009
  5          01/01/2010     06/30/2010
  6          01/07/2010     10/31/2010
```
He didn't exactly finish end of the month. Basically, I need these beaches of dates at apart 180 days.

I appreciate if someone can throw some ideas on this.

Thank you
Raj.
Hi, Raj,

Sorry, it is unclear what you are asking.

To generate a list of dates starting with min_sales_date and including all the 180 days after that up to (but not beyond) max_sales_date:
```
WITH     got_params     AS
(
     SELECT     DATE '2008-01-01'     AS min_sales_date
     ,     DATE '2010-10-31'     AS max_sales_date
     FROM     dual
)
SELECT     min_sales_date + (180 * (LEVEL - 1))     AS grp_start_date
FROM     got_params
CONNECT BY     LEVEL <= CEIL ( ( (max_sales_date - min_sales_date)
                                + 1
                       )
                     / 180
                     )
;
```
Output:
```
GRP_START_D
-----------
01-Jan-2008
29-Jun-2008
26-Dec-2008
24-Jun-2009
21-Dec-2009
19-Jun-2010
```
December 16, 2010 is 180 days after June 19, 2010, but it is not displayed, because is after max_sales_date, which is 31 October 2010.

I hope this helps you.
Whenever you have any questions, post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data.

Extending from weblogic security roles (groups) to jazn-"Data.xml" using SQLAuth...
Hello
as the title suggests is that I want to do...

The problem I encounter is that I can't map my Weblogic roles at a level of demand - roles.
I do not see my weblogic on jazn-"Data.xml" roles and I can't create groups to the application level because
everything works as SQLAuthenticator on Weblogic...
I can get the role of user with EL as #{securityContext.userInRole ['ROLE']} but it cannot apply to jazn-"Data.xml".

Hope that if anyone can help...
Thank you
Renan.

Hello

you create groups of jazn-"Data.xml" and then use the weblogic.xml file to map these business groups for groups returned by the SQLAuthenticator

Generation of the XML from the Oracle tables
I'm using Oracle 11 g R1.

I have two tables header and the line:

CREATE THE TABLE HEADER
(
EXPENSE_INFO VARCHAR2 (2000).
NUMBER OF ERROR_CODE,
REASON_OF_FAILURE VARCHAR2 (4000)
)
/

CREATE THE ROW IN THE TABLE
(
EXPENSE_INFO VARCHAR2 (2000).
DATE OF EXPENSE_DATE,
EXPENSE_CODE VARCHAR2 (10),
EXPENSE_REF VARCHAR2 (2000).
GROSS_AMOUNT NUMBER,
NUMBER OF TAX_AMOUNT,
NUMBER OF ERROR_CODE,
REASON_OF_FAILURE VARCHAR2 (4000)
)
/

These tables are linked by the EXPENSE_INFO column.

Complete the tables with the following data:

Insert in the header (ErrorCode, EXPENSE_INFO, REASON_OF_FAILURE)
values ('A', 0, 'SUCCESS');

Insert (EXPENSE_INFO, EXPENSE_DATE, EXPENSE_CODE, EXPENSE_REF, GROSS_AMOUNT, TAX_AMOUNT, ERROR_CODE, REASON_OF_FAILURE) online
values ('A', to_date (December 14, 2012 ', 'dd-mm-yyyy'), 'ABC', 'HOTEL', 100, 500, 0, 'SUCCESS');

Insert (EXPENSE_INFO, EXPENSE_DATE, EXPENSE_CODE, EXPENSE_REF, GROSS_AMOUNT, TAX_AMOUNT, ERROR_CODE, REASON_OF_FAILURE) online
values ('A', to_date (December 14, 2012 ', 'dd-mm-yyyy'), 'DEF', 'MOVIE', 10, 50, 1, "Cost Code does not exist.");

Insert in the header (ErrorCode, EXPENSE_INFO, REASON_OF_FAILURE)
values ('B', 1, "Emp Id does not exist.");

Insert (EXPENSE_INFO, EXPENSE_DATE, EXPENSE_CODE, EXPENSE_REF, GROSS_AMOUNT, TAX_AMOUNT, ERROR_CODE, REASON_OF_FAILURE) online
values ('B', to_date (December 14, 2012 ', 'dd-mm-yyyy'), "XYZ", "MILEAGE", 200, 300, 0, 'SUCCESS');

I'm not able to generate the XML file. Kindly help me.

Kind regards
Sudhanshu
I love working at the deepest level and then "wrap" with external level tags.

You want to list all columns of each LINE by line. XMLFOREST is good for this:
```
select xmlforest(
  expense_info, expense_date, expense_code, expense_ref,
  gross_amount, tax_amount, error_code, reason_of_failure
)
from line;

A
2012-12-14
ABC
HOTEL
100
500
0
SUCCESS
...
```
Now you want to wrap this up in EXPENSE_LINE_REC
```
select xmlelement("EXPENSE_LINE_REC",
  xmlforest(
    expense_info, expense_date, expense_code, expense_ref,
    gross_amount, tax_amount, error_code, reason_of_failure
  )
)
from line;


  A
  2012-12-14
  ABC
  HOTEL
  100
  500
  0
  SUCCESS
```
So far, you have a XML fragment by line in the table of the LINE. You can use XMLAGG to put those together in a single fragment - or rather, a fragment by EXPENSE_INFO.

Then you use XMLELEMENT again to give the name "EXPENSE_LINES" in this fragment.

Then you gather the header values and the 'EXPENSE_LINES' fragment in "EXPENSE_DETAILS". This gives you all the information for each row header and associated lines of the LINE.

Then, you gather all the information into one with XMLAGG header, and give everything a name with XMLELEMENT
```
select xmlelement("EXPENSES",
  xmlagg(
    xmlelement("EXPENSE_DETAILS",
      xmlforest(expense_info, a.error_code, a.reason_of_failure),
      xmlelement("EXPENSE_LINES",
        xmlagg(
          xmlelement("EXPENSE_LINE_REC",
            xmlforest(
              b.expense_date, b.expense_code, b.expense_ref,
              b.gross_amount, b.tax_amount, b.error_code, b.reason_of_failure
            )
          )
        )
      )
    )
  )
)
from header a join line b using(expense_info)
group by expense_info, a.error_code, a.reason_of_failure;
```
_Note: _ with the GROUP BY clause, you can 'total' twice, once at the expense_info level and then overall. That's what I do with the two XMLAGGs: the second he puts just all the different stuff EXPENSE_DETAILS together in one package that I wrap "CHARGES" tag autour.

Also, I omit EXPENSE_INFO of each LINE as it is already in the header information.

Generate the XML for double
Hey gurus,

I am trying to generate the XML code next to the double, however, I get an error message indicating that my higher level is not set. Any ideas? Thank you!

< PUDOOUTPUT >
< PKG >
< > 12345 SHIPMENTID < / SHIPMENTID >
< ERROR > 'NO DATA' < / ERROR >
< ERRORTEXT > "" error: could not find alias sender in SPL_SHIPPER_ACCOUNTS. "< / ERRORTEXT >"
< / PKG >
< / PUDOOUTPUT >

Select xmlelement ("PUDOOUTPUT", xmlelement ("PKG", xmlelement("SHIPMENTID",i.shipmentid),
XmlElement ("ERROR", "NO DATA")
XmlElement ("ERRORTEXT", "error: could not find the sender aliases in SPL_SHIPPER_ACCOUNTS.'")))
in p_wms_output
Double;
It works on 10.2.0.3
```
select xmlelement("PUDOOUTPUT",xmlelement("PKG",xmlelement("SHIPMENTID",123456),
xmlelement("ERROR",'NO DATA'),
xmlelement("ERRORTEXT",'Error: Cannot find shipper alias in SPL_SHIPPER_ACCOUNTS.')))
from dual;
```
I suspect the question is because you have "i.shipmentid" in your SQL statement you have to table with an alias of 'I' in your SQL statement. Do you mean something like l_shipmentid as a variable from your PL/SQL code?

Generate an equation from a graph XY

Hello

Does anyone know how to generate an equation from a graph XY. I had a set of data, generated a parcel interpolated the data set, and my model/curve is logarithmic. Although I would like to get the equation of the curve, the news, I'm really after are the slope and bias from the equation. This is the format I think that equation would be: y = (Slope) * ln (x) + Bias. Any help is greatly appreciated. Thanks in advance.

You try to run a journal able to Y = ln (x) m + c is no different to running an adjustment linear y = m x' + c, where x' = ln (x).

Yet, you can do it two ways:

Logarithm correspond to a sequence of X and will return amplitude and scale.

Consider a Y ln (bx). We know by simple logarithms ln (bx) can turn in ln (b) + ln (x)

If Y = a (ln (b) + ln (x))

Reorganization, ln (x) Y = a + a (b) ln (equivalent to your expression of the slope and bias)

where a is equal to "amplitude" and b is equal to "scale".

Linear adjustment of a sequence of X = ln (x) returns the slope and intersection.

Consider Y = m ln (x) + c = m X + c

The output of slope m, the point of intersection c.

Read xml from url

Hi all

I'm trying to get the data from this particular url: http://api.openweathermap.org/data/2.5/weather?q=London&mode=xml

I have no problem to scan directly from a .xml or xml string. But I can't read the data directly from labview or even save the file in the url as a .xml.

I already looked for example as reading and other http Web site, but has failed to adapt to my url.

If someone of you can help me

Thank you

The two of them seem to work here in LV 2011 very well:

Note that the other will require adding support for Datasocket if you build an installer and that the client HTTP screws have been added only around 2011.
