XML + CLOB

Hello

I do a mini-fonction to read a CLOB xml:

create the table XmlTest of XmlType;

DECLARE

localXML ClOB;

BEGIN

localXML: = ' <? XML version = "1.0" encoding = "utf-8"? > < message >
< Pippo id = "33" status = '0' / >
< Pippo id = "34" status = "1" / >
< id Pluto = "35" status = '0' / >
< id Pluto = '36' status = "1" / >
< Barcode id = "asfjhsfjkhwegjk22312312" status = '0' / >
< Barcode id = "sdklfjosgkdfgh596895354" status = '0' / > < / messages > ';

INSERT INTO XMLTEST VALUES (XMLTYPE (localXML));

END;

When I do:
SELECT x.getCLobVal (XmlTest) x;

The CLOB create a tag perfect for my job.

So, I want to insert the id value and status in another table (id is a varchar2 and status is a number). Is possible?

I use Oracle Database 10 g Enterprise Edition Release 10.2.0.4.0

Thank you.

Your Oracle client version must be incompatible with the server.

Could check you?

Hi Vanessa,

I see several issues here.

-L' example of XML document you gave is not well-formed.
-Some XPath expressions are false, i.e. they address anything in the document.
-You must also declare the namespaces that you use in XMLTable.

Assuming that the root element is actually "mslv - its: orderCompleteEvent", it should be better:

SELECT x.eventtime
FROM test_clob t
   , XMLTable(
       XMLNamespaces(
         'http://www.metav.com/oss/Sctivation/2003' as "mslv-sa"
       , 'http://java.sun.com/products/oss/xml/Common' as "co"
       )
     , '/mslv-sa:orderCompleteEvent'
       PASSING XMLTYPE(t.xml_file)
       COLUMNS eventtime timestamp PATH 'co:eventTime'
     ) x
;

Req SQL syntax. to extract the value XML [CLOB]
Hello

I'll have the XML column in my table.

I have XML value in CLOB data type. I had an experience using extract XML from SQL syntax.

But I am unable to extract this file. I need to meet tagname value XML who gave example below.

For example, the name of the Table is A
Column name is A1

The value of column given below here.

<? XML version = "1.0" encoding = "ISO-8859-1? > < tags > < tag > < tagname > {docval} < / tagname > < tagvalue > ESPRefNotice < / tagvalue > < / tag > < tag > < tagname > {: inputvalue} < / tagname > < tagvalue > 3216 < / tagvalue > < / tag > < tag > < tagname > {officename} < / tagname > < tagvalue > ssvofficename < / tagvalue > < / tag > < / tags >

Kindly help me on this to extract the value 'tagname' or 'tagvalue' according to the above xml data.

Thank you
```
SELECT warehouse_name warehouse,
 warehouse2."Water", warehouse2."Rail"

 warehouse2;
```
check this exp in the documentation
http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/functions228.htm#CIHGGHFB

the warehouse_spec is of type xmltype. So in your case it is clob then you need to add like what I did in the query...
XmlType ()...

Hope that explains everything...

How to extract a value of sql xml column clob data

Hi guys,.

I need help with the following. I have a column with data type xml (clob data). I need to extract the information in the < RI4 > tag and the < RI6 > tag.
I truncated the data, but there is a repetition of the < RI4 > tag and consequenty internal to that tag RI6. However, each tag RI4 and RI6 has different data.

I would be grateful if you can help me with this:

<a xsi:schemaLocation="som location.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:somlocation">

  </RI6>
  </RI5>
  </RequiredInformation3>
  </RequiredInformation2>
  </RequiredInformation>
  </a>

I think that since it's the repetition I might need to make some sort of PL/SQL programming, but I really need help here to build this announcement also a way to extract the information.

Any help would be greatly appreciated.

Kind regards

Any ideas to convert oracle XML or CLOB type collections
Hi all

Have actively tried to convert collections of oracle XML or CLOB objects to be stored in the table of database for logging purposes. Tried to look for clues. You can help.

Here is the script that I created temporarily to try the code:

DROP TABLE insert_table;

CREATE TABLE insert_table
(
Serial NUMBER (9),
first name VARCHAR2 (35),
name VARCHAR2 (35),
E-mail VARCHAR2 (65).
home_phone NUMBER (10),
work_phone NUMBER (10),
CONSTRAINT serial_pk PRIMARY KEY (serial)
);

DELETE FROM temporary_table;

INSERT INTO temporary_table VALUES (1, "Arthur", "Wright", "[email protected]", 5439021232, NULL);
INSERT INTO temporary_table VALUES (2, 'will', "Ball", "[email protected]", 4379021000, NULL);
INSERT INTO temporary_table VALUES (3, 'Kerwin","Mike","[email protected]", 9018236733, 6621232356);
INSERT INTO temporary_table VALUES (4, 'Krammer', 'Cone', '[email protected]', NULL, 3238483323);

DROP TYPE obj_detail FORCE

Hello

"" "You're almost there. '"

The error you have is because you try to refer to a local variable (the collection) in a static SQL string.
A solution would be to use a binding in the query variable, but only VARCHAR2 with DBMS_XMLGEN are allowed.

However, you can bind the collection using a REF CURSOR:
```
SQL> DECLARE
  2    ctx          DBMS_XMLGEN.ctxHandle;
  3    xml          CLOB;
  4    obj_det_list obj_detail_list := obj_detail_list();
  5
  6    rc           sys_refcursor;
  7
  8  BEGIN
  9
 10   SELECT obj_detail(serial,
 11                     last_name || first_name,
 12                     'Software',
 13                     'A')
 14   BULK COLLECT INTO obj_det_list
 15   FROM temp_table;
 16
 17   OPEN rc FOR SELECT * FROM TABLE(obj_det_list);
 18
 19   ctx := DBMS_XMLGEN.newContext(rc);
 20   xml := DBMS_XMLGEN.getXML (ctx);
 21   DBMS_OUTPUT.put_line (xml);
 22
 23   DBMS_XMLGEN.closeContext(ctx);
 24   CLOSE rc;
 25
 26  END;

Advice on the use of APEX_JSON with a CLOB in the body as a string

Hello all and thanks for any help in advance.
I have the task of liaising with a 3rd party API via JSON to send information to our database. First warning is the HOST for us is not and race so I have no way of properly this test until tomorrow, but I wanted to ask this question to try to overcome a potential problem.
In the body of the JSON object, we must add a chunk of xml (already created/kept or can be created on the fly) and it must be validated on as a long string. Now, this question is that the string can be up to 20000 characters long so when its processed is stored as a CLOB in the database (not made by me).
Now my thoughts early to do this was to create a procedure allowing certain parameters get the relevant piece of data and xml stored as a CLOB. Then and that's where I maybe need some tips, follow these steps.
This host requires JSON in this format
{
'batchcode': 1234562,
'XML string': 'THIS WILL BE a MASSIVE XML STRING',
""bounding ":" ",".
"ID": "123456465",
'field1 ':
.
.
etc.
}
We currently have a few apex applications so I got a good look at the documentation and allows to generate the required using JSON:
Thus to collect information of input parameters
APEX_JSON. INITIALIZE_CLOB_OUTPUT;
APEX_JSON. OPEN_OBJECT();
APEX_JSON. WRITE ("batchcode," value from database");
APEX_JSON. WRITE ("XML string ', our xml database that is stored as a CLOB string");
APEX_JSON. WRITE (bounding "," value of database");
APEX_JSON. WRITE ('ID', 'Value of database');
.
.
.
etc.
APEX_JSON. CLOSE_OBJECT();
Then validate using endpoint:
APEX_WEB_SERVICE. () MAKE_REST_REQUEST
p_url = > 'URL of the end point. "
p_http_method = > 'MESSAGE ',.
p_username = > API_USER,
p_password = > API_KEY,.
p_body = > apex_json.get_clob_output
);
Now assuming that my method is correct only the APEX_JSON. WRITING literally accept its entry as a type CLOB and he will be able to properly analyze or will it arrive at a mansion that will actually write the string itself?
Edit I found that if I APEX_JSON. WRITE ("XML", "CLOB table column") that it exported the CLOB but not in the format I want. This is due to the fact that my CLOB has characters like <>etc in II and the output is burning out in unicode, so for example <? XML version = "1.0" encoding = "UTF-8"? "> as stored in the object CLOB becomes \u003C?xml version=\"1.0\ ' encoding =------"UTF - 8\ '? \u003E\n in the output using APEX_JSON. To write.
The only other way to do it, I think it is so divided in pieces as follows:
SELECT ROWNUM as XML_PIECE_NO, TO_CHAR (SUBSTR (a.xmldoc, (ROWNUM-1) * 4000, 4000)) AS SECTION
Of ast_xmldata one
CONNECT (ROWNUM-1) * 4000 < = LENGTH (a.xmldoc)
Then maybe concat in the JSON long xml string field.
I hope I have explained what I want to do but if not please respond any help will be greatly appreciated.

EDIT I CAME FROM WITH a SOLUTION
Post edited by: K4E - found solution 02/04/2016

Thanks for the response of Christian, logical exit that way.

Through some trial and error, I found a solution to my problem that seems effective enough without having to worry about unicode characters written. There is seemingly a procedure without papers in the APEX_JSON package called apex_json.write_raw that does what it says. All I had to do then was to use escape characters in my CLOB for things like "then I get a few good valid JSON in the format of the API, I work with love."

Hope this helps someone else with the situation.

How to open a cursor-based XML data?
Hello

I use Oracle database 11g.

I have to write a stored procedure accepts an input of XML CLOB.

After receiving the CLOB, I am required to open a cursor to XML tags and then treat each record in "XML".

I don't know how to do this.

Recalled the following link: http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb03usg.htm#CEGDJEEI

But could not meet the requirement.

Appreciate your suggestions.

something
```
create or replace procedure prc (inxml clob, xml_cursor out  sys_refcursor)

x xmltype;

begin

   select xmltype(inxml) into x from dual;

   open xml_cursor for
         select extractvalue(x,'/tag') from dual;

I am able to store complements ti xml file database (10 gr 2) I want the in to extract the pdf part to an operating system file using utl_file.
How can I extract and convert to binary (?)

Best regards

So, if I understand it, the steps are

(1) load the xml files in db.
(2) extracts the xml clob data and stored in a clob
(3) convert the clob blob
(4) to decode the blob in the base-64
(5) print the blob converted to the os file

(3) pass the clob to the base64 binary data, and then store the result in blob
(4) write blob data to o/s using UTL_FILE writing in raw mode.

table col name get the details of the table column and inserting of values depending on the data type of the column

Hello

I am train to write a procedure where I would spend the table as a parameter name and then the code would determine it is column names, and then he would insert records in each column depending on the data type. could someone help me with this.

Thank you

Hello

Perhaps you need to dummy data just for the table.

Here is my exercise

create or replace
procedure generate_rows(p_table_name varchar2, p_count number)
is
  --
  function insert_statement(p_table_name varchar2) return clob
  is
    l_columns clob;
    l_expressions clob;
    l_sql clob default
      'insert into p_table_name (l_columns) select l_expressions from dual connect by level <= :p_count';
  begin
    select
      -- l_columns
      listagg(lower(column_name), ',') within group (order by column_id),
      -- l_expressions
      listagg(
        case
        when data_type = 'DATE'
          then  'sysdate'
        when data_type like 'TIMESTAMP%'
          then  'systimestamp'
        when data_type = 'NUMBER'
          then  replace('dbms_random.value(1,max)',
                  'max', nvl(data_precision - data_scale, data_length)
                )
        when data_type = 'VARCHAR2'
          then  replace(q'|dbms_random.string('a',data_length)|',
                  'data_length', data_length
                )
        else
                'NULL'
        end, ',') within group (order by column_id)
    into
      l_columns,
      l_expressions
    from user_tab_columns
    where table_name = upper(p_table_name);
    --
    l_sql := replace(replace(replace(l_sql,
      'p_table_name', p_table_name),
      'l_columns', l_columns),
      'l_expressions', l_expressions);

InPlace schema evolution error: ORA-31166: error code internal etc...

Hello

I have a table in which I will be storing an XMLTYPE column based on an XML schema. I use the following version of the database:

SQL*Plus: Release 11.2.0.1.0 Production on Thu Aug 23 18:20:12 2012

Copyright (c) 1982, 2010, Oracle.  All rights reserved.


Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

Now, when I run my test InPlace Schema Evolution, I get the following error message:

ORA-31166: internal error code to handle ignorable attributes

< / make >

I built a re-producable case of test for the purpose of this post on the forum. For starters, I have a database scheme grants the following privileges:

DIRECTLY GRANTED SYSTEM PRIVS
=============================
CREATE TRIGGER

CREATE TABLE

EXECUTE PRIVS (SYS-OWNED PACKAGES)

grant create table to DATA_ROLE with admin option;
grant create trigger to DATA_ROLE;
grant create view to DATA_ROLE;
grant select any dictionary to DATA_ROLE;

All other scripts are run as the database schema. For the purposes of clarity, let's call the {*} TEST_DB_SCHEMA {*}. I follow the steps below in this scheme:

NOTE: When I ran the above tests, I had already created the test of XML schemas. That's why the output messages, say...

H4. Now, as it is the first time I've ever tried evolution of XML schema in Oracle XMLDB, is there someone who could potentially open the door please, re. solve the ORA-31166< / police > error?

Hello

First of all, thank you for your efforts on the provision of a decent test case.

However, there are a few inconsistencies:

-Step 5 attempts to insert into SUBMISSION_BATCH, but the table created above is TEST_BATCH
-Same for the sequence name

Now back to the real question...

I think the problem comes because you run XMLDiff against two versions saved of your drawings.
When Oracle stores a schema, it adds a large number of attributes for internal use (you can see them by querying USER_XML_SCHEMAS. DIAGRAM) but we as end users don't have to worry about them.
However, by building the Xdiff document based on these two 'internal' versions, we explicitly say Oracle whose internal attributes must be changed during the evolution of the scheme, leading to potential conflicts.

A few other comments:
-Given that you're using the binary XML schema, you must also set "genTables-online false" and more "genTypes-online false."
-Also delete all annotations from xdb:defaultTable and xdb:storeVarrayAsTable on the diagrams, they are of no use in this situation.
-Do not save the schema of the v2, it is not necessary. Just use a transient instance when calling XMLDiff

So, to summarize:

-XMLDiff run against both original patterns (do not save a new in any case, the process of evolution will take care of replacing the old).
-of course, don't forget to change the INPLACE_TRACE to INPLACE_EVOLVE when ready :)

Hope that helps.

that error occurs generally when the parser attempts to read an incomplete XML file IE start tag does not match the final tag.
I see you will have an invalid XML, it's that your CLOB? If so, this would have caused the parser for error

Regexp_replace replaces no more
Hi all

I recently had to downgrade my version of 10.2.0.3 on 10.2.0.1 database (see below for more details).
Since this change, a call to regexp_replace no longer works.

Here is a code example:

DECLARE
CTX dbms_xmlgen.ctxHandle;
XML CLOB.
Req varchar2 (4000);
BEGIN
Req: = 'SELECT table_name FROM user_tables;
CTX: = dbms_xmlgen. NewContext (req);
dbms_xmlgen.setnullhandling (ctx, dbms_xmlgen. EMPTY_TAG);
XML: = dbms_xmlgen.getxml (ctx);
IF dbms_xmlgen. GETNUMROWSPROCESSED (ctx) = 0 THEN
XML: = ' <? XML version = "1.0" encoding = "ISO-8859-1? > ';
XML: xml = | ' < ROWSET / > ';
ON THE OTHER
XML: = regexp_replace (xml, ' ^ < \?xml(.+?)------? > ',' <? xml\1 encoding = 'ISO-8859-1'? > ')--call this work does'nt
END IF;
dbms_xmlgen.closeContext (ctx);
dbms_output.put_line ('* AFTER *' | xml);
dbms_xmlgen.closeContext (ctx);
END;
/
The output xml is empty ('* AFTER *' | xml) while it was not in the latest version.
I find no relationship between regexp_replace and Oracle 10.2.0.3.

TIA
Stephan

I still don't understand why you got no result at all, but perhaps the regexp_replace as l ' somehow the clob Locator.

Here is a list of alternatives to try instead of regexp_replace. You will lose some flexibility, we need to decide for yourself if they are substitutes.

(1) replace normal
```
xml := replace(xml, '', '')
```
(2) use XMLROOT as shown in one of the previous posts. This could ruin the "prettyprinting' of the clob. But there are functions to deal with that, if it is a problem.

(3) add the encoding later. It all depends on what you want to do with the clob. If you write it to a file, then you can probably do this stage

(4) delete the first line of the Clob object and add another line instead (bad idea I think. This will make things just slow and fragile.
```
v_line1 := ...
v_tempxml := ...
xml := v_line1 || v_tempxml;
```
(4) upgrade to oracle 10.2.0.4

Update an attribute XML in a CLOB to a table column

Hello world
I have a CLOB column in my table that carries a date XML. In which I need to update the attributes of the child when they repeat with the same parents several times in the data.
For example:
Say my XML data as follows.
<? XML version = "1.0"? >
" < sample xmlns =" https://www.ABC.com "> "
< a > detail first line 
second line of detail/< c >/< c >
< /a >
< d > < c > Paris/< c > < / d >
< d > < c > France/< c > < / d >
Japan < d > < c >/< c > < / d >
< /sample >

I want to update as
<? XML version = "1.0"? >
< sample xmlns = " https://www.ABC.com "> "
< a > detail first line 
second line of detail/< c >/< c >
< /a >
< d > < c1 > Paris < / c1 > < / d >
< d > < c2 > France < / c2 > < / d >
Japan < d > < c3 > < / c3 > < / d >
< /sample >

I have tried to identify the repetition of my parent attribute using the sub query and I tried updating their attribute by extracting the XML data for each attribute parent in a loop. But it does not work

Select xml_load where xml_name = "sample1"; regexp_count (xml_val,' <d> ') -Giving more than 10K as County

Identified the attributes of the parent for help,
Select
Count (1)
of xml_load x
where existsNode (extract (xmltype (xml_val),'/ * [local - name () = "sample"]'),)
(' / d ') = 1 - he never returned me 1. I couldn't understand why as there is an attribute called < d >.
Please provide your help in achieving my requirement. Any help would be greatly appreciated.

I guess you want to insert an attribute in the existing xml document. So my suggestion is, instead of UPDATEXML you can just use INSERTCHILDXML. The following code works correctly. Hope this will be the final XML format

-Code

DECLARE

l_col1 XMLTYPE.

Nt_xml TYPE TABLE IS NUMBER;

l_ntxml nt_xml: = nt_xml();

BEGIN

XMLTYPE (xt.xml_val) SELECT col1 INTO l_col1

OF xml_test xt

WHERE xt.xml_name = 'file sample.xml ";

SOME pos

LOOSE COLLECTION l_ntxml

OF xml_test xt.

XMLTABLE (xmlnamespaces (DEFAULT "http://www.abc.com'),

"/ Report/identifier/area/CodeCategory.

PASSAGE xmltype (xt.xml_val)

COLUMNS pos for ORDINALITE

)

WHERE xt.xml_name = 'file sample.xml ";

BECAUSE me IN 1.l_ntxml. COUNTY

LOOP

SELECT INSERTCHILDXML (l_col1,'/ report/identifier/area/CodeCategory ['| l_ntxml (i) |'] /Code','@id',l_ntxml (i) ','xmlns = "http://www.abc.com" ' ")

IN l_col1

DOUBLE;

END LOOP;

-DBMS_OUTPUT. Put_line (l_col1. GetClobVal());

UPDATE xml_test SET xml_val is l_col1. GetClobVal() WHERE xml_name = "sample.xml";
