Extract a specific node of XMLTYPE value

I have a piece of code that puts an answer Google geocoding in an XMLTYPe variable. I then use lines similar to the following to retrieve values such as address and location:

px_xml.EXTRACT('/GeocodeResponse[1]/result['||pn_result_number||']/formatted_address[1]/text()').getstringval();

It's a pretty lazy way of just looping through my results and picking a specific value.

Now, I need to extract just the addresses zip_code of XML component and can't do in the same way. Someone at - it ideas?

A call to the example is:

https://maps.googleapis.com/maps/API/geocode/XML?address=London+Eye & Bounds = 49.90878, - 7.69042. 60.88770,-0.83496 & key =

but you need to add your own key to operate. There are several components of the address and I just want to identify who has the type "zip_code".

Thank you!

It's a pretty lazy way of just looping through my results and picking a specific value.

And what about using a more friendly approach, XMLTABLE namely:

Extract data from complex XML of XMLType with nodes parents containing several internal nodes

Use an XPath predicate to target only the required component, for example:

select x.long_name
from xmltable('/GeocodeResponse/result'
       passing px_xml
       columns
         long_name   varchar2(200) path 'address_component[type="postal_code"]/long_name'
     ) x
;

Extraction of a node in an XMLtype table - selection of the previous query
Hey all,.

I work with a server Oracle 11 g r2 and basically need to be able to analyse and select nodes from it. I spent hours scouring the net and reading the manual oracle xml db trying to find an appropriate solution to my problem, but I can't seem to identify the correct way to do it. I have some experience in programming, but none with databases oracle, sql or xml in general so forgive me if this is a trivial question.

OK, so the question:

I have a very simple XML file saved under catalog.xml and it is as follows:

<>Catalog
< cd >
< title > hide your heart < /title >
< artist > Bonnie Tyler < / artist >
< Country > UK < / country >
< company > CBS Records < / company >
< price > 9.90 < / price >
< year > 1988 < / year >
< CD >
< cd >
Empire Burlesque < title > < /title >
< artist > Bob Dylan < / artist >
< country > USA < / country >
< company > Columbia < / company >
< price > 10.90 < / price >
< year > 1985 < / year >
< CD >
< / catalogue >

Now, I want to be able to extract the title of the given cd a certain artist. So, for example, if the artist is "bob dylan", the title should be "empire burlesque".

Now I created an XMLType table in Oracle as follows:

CREATE BINARY XMLTYPE STORE AS XML BINARY XMLType TABLE.

I then load my xml file into oracle by:

Insert the BINARY values (XMLTYPE (BFILENAME ('XML_DIR', 'catalog.xml'), nls_charset_id ('AL32UTF8')));

So far so good.

Now for the part of the excerpt:

First of all I've tried:

SELECT extract (b.object_value, ' / catalogue/cd/title ')
Binary b
WHERE existsNode (b.object_value,'/catalog/cd [artist = "Bob Dylan"]') = 1;

EXTRACT(B.OBJECT_VALUE,'/CATALOG/CD/TITLE')
--------------------------------------------------------------------------------

< title > hide your heart < /title >
Burlesque Empire < title > < /title >

1 selected line.

It did not work because the xml file was all in 1 row then I realized that I had to split my xml in separate rows. Doing that, I had to convert the nodes < title > a virtual table using the functions XMLSequence() and table(). These functions convert nodes two title returned by the extract() function in a virtual table composed of two XMLType objects, each of which contains a single title element.

Second test:

SELECT value (d)
Binary B,
Table (xmlsequence(extract(b.object_value,'/catalog/cd'))) d
WHERE existsNode (b.object_value,'/catalog/cd [artist = "Bob Dylan"]') = 1;

VALUE (D)
--------------------------------------------------------------------------------

< cd >
< title > hide your heart < /title >
< artist > Bonnie Tyler < / artist >
< Country > UK < / country >
< company > CBS Records < / company >
< price > 9.90 < / price >
< year > 1988 < / year >
< CD >

< cd >
Empire Burlesque < title > < /title >
< artist > Bob Dylan < / artist >
< country > USA < / country >
< company > Columbia < / company >
< price > 10.90 < / price >
< year > 1985 < / year >
< CD >

2 selected lines.

It's better because it is now divided into 2 different lines so I should be able to make a selection - where, and then select the title from the artist.

However, this is where I have questions, I tried to literally hours but I can't understand how to use the results of the query above in my next. So I tried to use a suquery in this way:

Select extract (sub1, ' cd/title')
Of
(
SELECT value (d)
Binary B,
Table (xmlsequence(extract(b.object_value,'/catalog/cd'))) d
) sub1
WHERE existsNode (sub1,'/ cd [artist = "Bob Dylan"]') = 1;

However, sql * plus displays an error:

ORA-00904: "SUB1": invalid identifier.

I've tried dozens of variations to try to use subqueries but I simly can't do things.

I heard you can do also do this using variables or pl/sql, but I don't know where to start.

Any help would be greatly appreciated I tried everything at my disposal.
This should help you get started!

Questions about the management of specific nodes in different hierarchies

Hi all
I have a question about the specific management of some particular set nodes, which are located in different hierarchies within a same version.
I want to know if there is any editing made to certain properties of these specific nodes or if the nodes are deleted/moved/edited approval to be triggered for the data manager.
or should not allow users to edit (adding/moving/deleting/changing property values) or those specific members.

According to my understanding of the nodes of domain prevents the removal of nodes, but I don't want my Member prefix/suffix, domain is the only way to prevent the change.

Thanks and greetings
Madhu

We have an obligation to not allow a node to remove or deleted without the approval of the admin, so I created a Boolean property AllowDelete is false, which is substitutable, default and is available only in a category of property Admin, for which most of the users do not have access. Then, I created a validation of PropRemove with an error message that tells the user to contact a user admin to remove or delete the node. The admin can change the AllowDelete to true, then can either remove himself or to allow the user to do.

How to call the specific node of the navigation model?
Hello

I have a portal application webcenter containing a custom navigation template. HIES model is used by the menu tree and bread crumbs.
Users request a link in the template to navigate to the home page. I could make a case of navigation in my ADFC-config file to navigate to the home page, but I would rather use the navigation model. Is there a way to select a specific node in the navigation model and navigate using a button or a link?
I've been looking for this much time, but could not find an example. It's has enough of the menu etc, but not cela.
Thank you...
You can use the same navigation model just like using the template of menu xml

PIN dbms_cube.build jobs parallel to a specific node on the CARS
Is it possible to Pin dbms_cube.build jobs parallel to a specific node on CARS. Currently, work with say parallelism of 10 bays on all nodes of the RAC.

Is it possible to control for the jobs of the child works on the subset of nodes. Unable to see how we can link to categories of jobs and services with dbms_cube.build.

Any suggestions will be much appreciated.
JOB_CLASS was added in 11.2.0.2 precisely for this purpose. It is undocumented, because he missed the 11.2.0.1. Deadline for documentation, but it has exactly the same meaning as the job_class parameter in DBMS_SCHEDULER. CREATE_JOB.

Check the value of the attribute of a child node to xmltype data type.

Hello

I have a xml stored in the column with the data type as "XMLTYPE.

<?xml version="1.0" encoding="ISO-8859-1"?>
<Settings>
  <Setting Name="A1" Value="N"/>
  <Setting Name="A2" Value="N"/>
  <Setting Name="A3" Value="SOMEVALUE"/>
  <Setting Name="A4" Value="N"/>
  <Setting Name="A5" Value="Y"/>
  <Setting Name="A6" Value="N"/>
</Settings>

I don't want to loop in each child node. But want to know if the value of the A5 parameter is Y or N? Is there a way I can find it without making the child node extract "Setting" and then a loop of each node to find the value?

Kind regards

You specify your Oracle version then here are two options. If 10.2 or higher, use XMLTable, otherwise use the option of ExtractValue.

-- The WITH simply simulates your existing table that I do not have.
WITH fake_tab AS
(SELECT XMLTYPE('

  
  
  
  
  
  

') tab_col
  FROM dual)
-- For 10.2 and higher use this SELECT
SELECT a5
  FROM fake_tab,
       XMLTABLE('/Settings'
                PASSING fake_tab.tab_col
                COLUMNS
                a5   VARCHAR2(10)  PATH 'Setting[@Name="A5"]/@Value');

-- For 10.1 and before
SELECT ExtractValue(tab_col, '/Settings/Setting[@Name="A5"]/@Value')
  FROM fake_tab;

I can extract a value for FULL-TIME 1 or 2, is not a problem.
However, how can I go on the selection of a value of an attribute below FULL-TIME X, where X is the maximum value of FULL-TIME in any node in the XML document?

I tried to the last node corresponding to my way, but it is not always the case that the FULL-TIME max will correspond to this scenario.

Any help would be greatly appreciated!

Thank you very much, Pete

Retrieve / search a specific node of the XML file
Hello

I have a question about reading the XML (search) in PL SQL file:

There is an XML file with the following structure:
```
<root>
  <Hnode1 attr1="value1" />
  <Hnode2 attr1="value1" /> 
     <node1_of_Hnode2 id="10" personname="Steven"/>
     <node2_of_Hnode2 id="20" personname="Christian"/>
     <node3_of_Hnode2 id="30" personname="Arnold"/>
     .
     .
  <Hnode2/>
<root/>
```
How it is possible to filter a node by one of its attribute value. For example:
The id of a person - I guess that id = 20. In this case I would like to get the whole node (in this case node2_of_Hnode2) to get the personname = > 'Christian '.
Just like a SELECT statement (WHERE ID = 20)

Is it possible to get it in a single order or should it be buckled on all the lines in the Document. Can you please provide an example for me.

Thank you for advice!
The basic version is 10.

Sorry, this is not a version.
For example:
```
SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
PL/SQL Release 10.2.0.5.0 - Production
CORE     10.2.0.5.0     Production
TNS for 64-bit Windows: Version 10.2.0.5.0 - Production
NLSRTL Version 10.2.0.5.0 - Production
 
```
The use of the extraction of the values?
1. better in a Select statement. assignment directli in a variable, or by using the xmlquery function?

PL/SQL or SQL calls to the XMLType methods such as getStringVal() or extract() function should be equivalent (save the change of context).
However, none of them are the right way to retrieve a scalar value of a given node.
You must use the rather extractValue() function (SQL only) for immediate release< 11.2="" and="" xmlcast/xmlquery="" starting="" with="">

Another Question:

I've seen a lot of options for dealing with XML files.

In my case only query data in XML files is relevant.

I've seen to many API called XMLDOM, DMBS_XMLDOM, XMLTYPE...

When to use these APIs. Can you give me feedback on this please?

It is a broad topic.
An appropriate response will depend on your condition.

-You have to deal with large files and if so what size?
-Performance/memory management is a concern for you?
-You want to extract unique values or process the XML content in the form of relational data?

If you have any specific test cases to show us, please post in the {forum: id = 34} forum and make sure to include all the necessary details (see the FAQ).

but that just ends up with the following error (of course): ORA-19279: dynamic XQuery type mismatch: expected - singleton sequence got several sequence element

Any ideas on how I can do to get this snippet? I would like to make in a single call XMLTABLE if I can, but it is probably not possible - otherwise, I'm happy to go with another call to XMLTABLE if necessary.

Thank you.

PS. I'm on Oracle 10.2.0.4

Extraction of data to xml by value
How can I retrieve from an xml value by value?

In this example, I need to extract one by a pair of LABEL / VALUE:
pLABEL = pVALUE 101 = A
pLABEL = 102 pVALUE = B
pLABEL = 102 pVALUE = C
pLABEL = 102 pVALUE = D

If I run the query in this example, I get all the data at once:

ABCD
101102103104

PL/SQL procedure successfully completed

The labels are not always the same.

DECLARE
t varchar2 (1000): =' < tip t = "1" > '
||     ' < info > < label > 101 < / label > < value > < / value > < / info > '
||     ' < info > < label > 102 < / label > < value > B < / value > < / info > '
||     ' < info > < label > 103 < / label > C < value > < / value > < / info > '
||     ' < info > < label > 104 < / label > D < value > < / value > < / info > '
||     "< / Tip >."
v_xml XMLType: = XMLType (t);
r varchar2 (1000);
pLABEL number (10);
VARCHAR2 (10) pVALUE;

BEGIN

Select extract(v_xml,'//tip/info/value/text()').getStringVal () in double r
where existsNode (v_xml, '//tip/info [label = "101"]') = 1;
dbms_output.put_line (substr (r, 1, 255));

Select extract(v_xml,'//tip/info/label/text()').getStringVal () in double r
where existsNode (v_xml, '//tip/info [label = "101"]') = 1;
dbms_output.put_line (substr (r, 1, 255));

END;

You will need to use a function to return the nodes of a collection as a set of lines. In 10g, it is table (xmlsequence ()). 11 g, you can use XMLTABLE().

Here is a sample of 10g:

Select
ExtractValue (value (p), "/ info/label") label.
ExtractValue (value (p), "/ info / value ') value
Of
table)
xmlsequence)
extract)
XmlType)
' < Tip t = "1" >
< info > < label > 101 < / label > < value > < / value > < / info >
< info > < label > 102 < / label > < value > B < / value > < / info >
< info > < label > 103 < / label > C < value > < / value > < / info >
< info > < label > 104 < / label > D < value > < / value > < / info >
< / tip > '
)
,'/ / info'
)
)
) p ;

Prevent the change of name of specific nodes

Hi all
DRM can we prevent the renaming of the names of nodes for certain specific levels in the hierarchy and not the whole hierarchy.
Preference of the system RenameLimb/Renameleaf can be prevented, but it is a property of the system and changing this property applies to any application and all versions.
I want my restriction to only specific hierarchy and levels.
Can any validations or it's training of security privileges will in this scenario.
Thank you
Madhu

Hi Madhu,

Have you tried to use access to the node groups and granted read only access to the relevant level?

Transfer values of ROWTYPE in ROWTYPE with different COLUMN specifications. keeping the Default_Data values

Hello
I have a problem on dynamically the transfer values of different columns in two variables given rowtype type.
My intention is to transfer values from table1 into table2.
Basically, I stated to vars of v_table1 and v_table2% rowtype, each of them contains columns with the same, and also the individual column names.
v_table2% rowtype must be initialized with default values.
I would like to insert v_table2 values in table2 later by practice 'INSERT INTO TABLE2 VALUES v_table2'.
Before inserting, I need to change several values of column by different rules, but these rules are not relevant for my actual demand.
The point is, how can I transfer the values of v_table1 in v_table2 for the hanving of columns with the same column name, without hard-coding the names of columns, because these two tables contain many columns.
In addition values initialized with v_table2 default_data values should not be overwritten by data does not exist in the same named column of v_table1.
Example: If v_table1. D is NULL, it should not replace the default value initialized former "Monday".
Conditions:
Table 1 contains the following values:
Column name Value
A '1'
B '2'
C NULL VALUE
D 'somedata '.
E NULL VALUE
F « 3 »
After the transfer of the values of v_table1 in v_table2, I guess that the following data:
Column name Value Source
C NULL VALUE Table1.C
D 'somedata '. Table1.D
E "Tuesday". DATA_DEFAULT from Table2
F « 3 » Table1.F
G NULL VALUE
H NULL VALUE
Right now I am already able to fill the v_table2 with the default values:
```
declare
  lv_query varchar2(1000);
  
  type cur_typ is ref cursor;
  rcur_typ cur_typ;
  
  v_table2 table2%rowtype;

begin
    for rec in (select *
                from user_tab_columns
                where table_name = 'TABLE2'
                order by column_id
                )
    loop
      if rec.data_default is null then
          lv_query := lv_query||', null';
        elsif rec.data_type = 'NUMBER' then
          lv_query := lv_query||', '||rec.data_default;
        elsif rec.data_type = 'DATE' then
          lv_query := lv_query||', '||rec.data_default;
        else
          lv_query := lv_query||', '||rec.data_default||'';
      end if;
    end loop;
    
    lv_query := 'SELECT'||substr(lv_query, 2)||' FROM DUAL';
    dbms_output.put_line(lv_query);
    
    open rcur_typ for lv_query;
    fetch rcur_typ into v_table2;
    close rcur_typ;
end;
```
I have no idea how to achieve the transfer of v_table1 to v_table2 without substitute default values of table2.

As far as I know I can find these columns with column names by querying:
```
select column_name from user_tab_cols where table_name='TABLE1' intersect select column_name from user_tab_cols where table_name='TABLE2'
```
Maybe you can give me some advice.
Thank you very much.
Sample data:
```
CREATE TABLE "TABLE1" 
   (    "A" VARCHAR2(20 BYTE), 
    "B" VARCHAR2(20 BYTE), 
    "C" VARCHAR2(20 BYTE), 
    "D" VARCHAR2(20 BYTE), 
    "E" VARCHAR2(20 BYTE), 
    "F" VARCHAR2(20 BYTE)
   );

  CREATE TABLE "TABLE2" 
   (    "C" VARCHAR2(20 BYTE), 
    "D" VARCHAR2(20 BYTE) DEFAULT 'Monday', 
    "E" VARCHAR2(20 BYTE) DEFAULT 'Tuesday', 
    "F" VARCHAR2(20 BYTE) DEFAULT 'Wednesday', 
    "G" VARCHAR2(20 BYTE) DEFAULT 'Thursday', 
    "H" VARCHAR2(20 BYTE)
   );

INSERT INTO "TABLE1" (A, B, D, F) VALUES ('1', '2', 'somedata', '3');

INSERT INTO "TABLE1" (A, B, D, F) VALUES ('1', '2', 'somedata', '3');

You can build a dynamic query that checks the values of all columns in the table 1,

and if a column contains null, then retrieves the default value of the column in table2,

or null if this column doesn't have a default vallue.

Something like this pseudocode
```
SELECT
   if column A is not null then take A from table1, else take default for column A from table2
   .....
   if column X is not null then take A from table1, else take default for column X from table2
FROM table1
```
The default budget can be extracted from USER_TAB_COLUMNS
```
select column_name, data_default from user_tab_columns
where table_name = 'TABLE2'
order by column_id
;
```

Hierarchy of the building under a specific node in the outline
Hello

We have an obligation to create a hierarchy under a specific dimension member in the sketch. We have the dimension of time in which there are two nodes 'Time_Hierarchy379' and 'Time_Hierarchy383', now we need generate a rule file that generates a hierarchy, 4 levels deep, under the node 'Time_Hierarchy379 '. The construction of a hierarchy, to use the reference level or generation method, but how do you ensure that the hierarchy is built under the node "Time_Hierarchy379" specifically? Members 'Time_Hierarchy379' and 'Time_Hierarchy383' have been created manually, and they are not a part of the data in the source dimension tables. Help, please.

Thank you
Krishna
It is not necessary that these two members is a part of the data in the source table.

During the creation of the rule file, you can insert a column with 'create text using... "and specify the Member under which you want the hierarchy must be created. Label with appropriate generation and level and you should be able to build the desired hierarchy.

Kind regards
Sunil

Column name	Value	Source
C	NULL VALUE	Table1.C
