• Questions to extract the XMLtype column attributes

  I cannot retrieve the values of a column of the XML data type. There are 16 fields and when I try to extract the data the XML snippet is that each of them in 1 great return value.

• extraction of xmltype and excluding all the tags of the namespace?

  Hi all
  I am trying to extract the xmltype column in another xmltype column in another table.
  
  Select xt.attachment_content, xt.attachment_type, xt.attachment_format
  OF document_version dva.
  XMLTABLE)
  XMLNamespaces ('http://oracle.com/test1/1.0'),
  "AttachmentList/attachment.
  
  PASSAGE document_content
  COLUMNS
  attachment_content path of xmltype "content."
  path of varchar2 (100) to attachment_type 'type,'
  XT attachment_format varchar2 (100) path 'format')
  
  This query returns results, BUT the content has tags and namespaces in the game too. I just want to return the content than ANY version of xml without xmlns: (xmlnamespaces) and etc.
  
  Please help me how to do this.

  OK, thanks for the effort, however, this is not a test case from work, by far...

  The input XML is not valid because you probably just copied the version without escape sequence and paste here.
  The cuts you made in the XML load make invalid too.

  The query is not true either, syntax XMLNamespaces is bad, but also the XPath expression.

  I understand that you want to present a simplified scenario based on but you are in fact wasting time by not giving something that we can run.

  Now, if I have a query document_attachments table content column displays the results, but with all the tags of the namespace and etc.

  As said, I doubt that the request you give will never recover anything, but that is a different problem.

  What I would like to know because my first answer is why namespaces are a problem for you? They are part of the document and it is easy to deal with them once we know how to do it.

  For example, this retrieve the value of the content as CLOB (plain text) and convert on the fly of XMLType:

  INSERT INTO document_attachments (doc_id, content, type, format)
  SELECT dva.doc_id
       , xmlparse(document xt.attachment_content) as content
       , xt.attachment_type as type
       , xt.attachment_format as format
  FROM document_version dva
     , XMLTable (
         XMLNamespaces(default 'http://optimal.com/SP/2/RandPCommon/DocumentStore/GatewayRequestStore/1.0')
       , 'AttachmentList/attachment'
         PASSING document_content
         COLUMNS
           attachment_content clob          path 'content'
         , attachment_type    varchar2(100) path 'type'
         , attachment_format  varchar2(100) path 'format'
       ) xt
  ;
  

  Now, the contents column is:

  
  
   
  
    
  
     6
     6
    
   
   
    
     /1/2/28/8

      U
      TX
     
    
    
     /1/2/27/8
     /SSRF/Body/Location[@serial='USA:AF:LT:7c5c3cef2cf74ef']/Address[1]/@country
     
      
      Brownsville
      U

• How to extract a string from a varchar column value

  Hello
  I have a varchar2 column that got the xml data. I want to extract the value of a tag < test > < / test >
  
  I can't use EXTRACT because the column is not XMLTYPE.
  
  Please suggest.

  Insert first only the first two columns:

  INSERT INTO TESTXML (id,name) VALUES(1, 'ABCDEFTEST');
  INSERT INTO TESTXML (id,name) VALUES(2, 'XYZUVWTEST');
  INSERT INTO TESTXML (id,name) VALUES(2, 'XYZUVWTES');
  

  Make this update:

  update testxml set temp=rtrim(ltrim(regexp_substr(name,'(.*?)'),''),'');

  Or what is the problem here?

  -Thank you

  Hello

  Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  PL/SQL Release 11.2.0.3.0 - Production

  CORE Production 11.2.0.3.0

  AMT for Linux: Version 11.2.0.3.0 - Production

  NLSRTL Version 11.2.0.3.0 - Production

  Trigger Before Insert or Update to a table, I invoke a PL/SQL package function to check the size of an xmltype column (passing as IN OUT NOCOPY).

  PL/SQL functions retrieves the xmltype. GetClobVal(), check its size, and when it is beyond a limit, he tries to insert the data into another table (GTT - global temporary table).

  Finally, it changes the value of the value of the column of xmltype to the shorter XML (just by referring to the corresponding record in the TWG).

  But the Insert SQL in the TWG operation strike ORA-22993: specified input is greater than the amount actual source.

  I don't know why this happens. In the internet I only find references on importing files in lob/clob.

  Anyone have the same problem?

  I know that you prefer to have a sample program to demonstrate the problem - I'll try to post one, but it will take time.

  But maybe someone can help me based on the information above already.

  -Thanks a lot!

  Best regards

• Compare the values of the XMLType column to two different lines using XMLDiff in GR 11, 2

  I have a table of data with a row of XMLType and I need a way to compare the XML data against the other. I guess I could use a function and return a XMLDIFF base output to the caller, but the function logic is a bit fuzzy. Would be nice to format the output finally in a table format.
  
  I looked on http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions241.htm#SQLRF20025 and output in a format of table as shown in Re: how to find compare and identify between xmldocs .
  
  I ran across some examples do not explain the best way to compare the XML code that is in the best performing XMLType column.
  
  Any help would be appreciated.

  Are you referring to different rows in the same table or different tables or?

  Basically, you need to change the example of Odie so that the XMLDiff retrieves the XML from places in Pb, say something like

  XMLDIFF(SELECT aXml FROM table WHERE ...,
          SELECT bXml FROM table WHERE ...)
  

  This allows to avoid bringing the XML of the DB in the client code.

  Don't know if that's what you're looking for, but hopefully it helps a little.

  insert into rds_xml_config values ('TRANSMIT_SEQ', 'INTERFACE',' < transmit_seq > <!-file sequence number will be updated after each race-> < file = "RTP" Type_de_fichier > < file_seq_num > 2457 < / file_seq_num > < / file > < file Type_de_fichier = 'RTS' > < file_seq_num > 2453 < / file_seq_num > < / file > < Type_de_fichier = "RTL" file > < file_seq_num >) 2522 < / file_seq_num > < / file > < / transmit_seq > ');

  I have to add < file = "RTX" Type_de_fichier > < file_seq_num > 0 < / file_seq_num > < / file >.

  As a temporary work around, I used below the update statement.

  Update rds_xml_config

  Set config_xml =' < transmit_seq > <!-file sequence number will be updated after each race-> < file = "RTP" Type_de_fichier > < file_seq_num > 2457 < / file_seq_num > < / file > < file Type_de_fichier = 'RTS' > < file_seq_num > 2453 < / file_seq_num > < / file > < Type_de_fichier = "RTL" file > < file_seq_num > 2522 < / file_seq_num > < / file > < file = "RTX" file_type > < file_seq_num > 0 < / file_seq_num > < / file > < / transmit_seq > '

  WHERE module_type = "INTERFACE".

  AND module_name = "TRANSMIT_SEQ";

  SEQ numbers will be modified for each race of the file, so I cannot use the work temporary around during migration to production, have we a way to add new XMLtag.

  Thank you

• Ask about the structured storage of XMLTYPE column in Oracle Xml db

  Dear all,

  Version of DB: Oracle 11g (11.2.0.3.0)

  I have a table with an XMLTYPE column with a structured storage.

  CREATE TABLE Orders
      (
      Order_id NUMBER NOT NULL,
      Order_etc VARCHAR2(100),
      Order_desc XMLType NOT NULL
      )
      XMLTYPE Order_desc STORE AS OBJECT RELATIONAL XMLSCHEMA  "http://localhost/public/xsd/order_desc_xsd.xsd" ELEMENT "OrderState";
  

  I then recorded the XSD XML Db schema that is required for the structured storage.

  Before the creation of the table, I had created a table XMLTYPE (db_objects) and was able to use the query to verify that all objects, the XMLTYPE table got broken into when I signed his XSD below.

      SELECT column_name,      
             data_type
      FROM   user_tab_cols
      WHERE  table_name = 'DB_OBJECTS';
  

  And used under query to find data stored in the object-relational structure for my table (DB_OBJECTS) created with definition of XMLTYPE.

    SELECT EXTRACTVALUE(xseq.column_value, '/THISROW/OWNER')       AS owner
      ,      EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_NAME') AS object_name
      ,      EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_TYPE') AS object_type
      ,      EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_ID')   AS object_id
      ,      EXTRACTVALUE(xseq.column_value, '/THISROW/CREATED')     AS created
      FROM   db_objects do
       ,      TABLE(XMLSEQUENCE(EXTRACT(VALUE(do), '/ROWSET/THISROW'))) xseq  
      WHERE  ROWNUM <= 10;
  

  Now could someone let me know, How to find how the column of XMLTYPE (Order_desc) was divided between other objects, just as I did for the Table with XMLTYPE (as shown above)?

  Thank you very much.

  First of all, because you are on 11.2, ExtractValue is obsolete and the documentation lists three options to use instead.  Here's an (untested) option

  SELECT owner, object_name, object_type, object_id, created
    FROM db_objects do,
         XMLTable('/ROWSET/THISROW'
                  PASSING do.object_value
                  COLUMNS
                  -- Set data types accordingly
                  owner        VARCHAR2(20) PATH 'owner',
                  object_name  VARCHAR2(20) PATH 'object_name',
                  object_type  VARCHAR2(20) PATH 'object_type',
                  object_id    VARCHAR2(20) PATH 'object_id',
                  created      VARCHAR2(20) PATH 'created');
  

  Secondly, why the column order matter?  You store in a method of object / relational.  As long as the XML is valid per the schema, Oracle will be able to store the data and thus to retrieve later.  How these data are mainly internal Oracle and shouldn't be touched because it can be changed from one version to another.  You can use the schema annotation to control how Oracle cards and stores the XML content, but nothing in there specifies the column order I know.

  It seems several details are missing information which could help others to answer your question as to what you need.

• The xmltype column search and listing content in relational format

  Hi all
  
  I have a database of GR 11, 1 subject table containing the xmltype column. I'm writing a query that displays conetents xml in a relational format.

  My goal is to search for documents TRANSFER_LOGS for lines that contain flaws: attribute name = "circuit.exception". Then report "fault: name attribute" and their values in relational format. For example:
  

  TRANSFER_ID    TRANSFER_RESULT FAULT_FAIL_REASON    FAULT_CIRCUIT_EXCEPTION                               FAULT_WS_NAME   FAULT_DESTINATION_HOST
  ----------     --------------- ----------------     -------------------------------------------------------- -------------   ---------------------
  T3217          REJECTED       CONNECTION REJECTED  com.es.circuit.CircuitAbortException: connection rejected  PUSHDOC       es.live.com

  I am new to oracle XML sql querying. Documents in the column of xmltype TRANSFER_LOGS have many namespaces and the query I've tried does not work. So, any help or pointers to search and extract TRANSFER_LOGS in above format is greatly appreciated.
  
  Thanks in advance.

  I want to create indexes for child nodes. I read THAT XML structure cannot have collection as index it should be singleton.
  So can someone tell me no work around to create indexes for these nodes, or whatever it is that I missed as follows.

  Note the first example XMLTable does not use the index because the data type of AMOUNT is given wrong...

• excerpt from the XMLType column

  In my XMLType column I'm storing XML content that is the xml below.

  <? XML version = "1.0" encoding = "UTF-8"? >

  How to write a query to extract the Application name?

  Here, it should return "anais" and "yu123".

  I'm using Oracle 11 g.

  Thanks in advance.

  Something like the following, where TMP_XML. DOC is my XMLType column:

  SQL> select x.*
    2  from tmp_xml t
    3     , xmltable('/Project/Children/Application/Basics'
    4         passing t.doc
    5         columns application_name varchar2(30) path 'Attribute[@Name="Name"]'
    6       ) x
    7  ;
  
  APPLICATION_NAME
  ------------------------------
  rty
  yu123

  [/ code]

  Like the above, I have an xmltype in a table that has other non-xmltype columns.   I have a requirement to extract them out in a single xml document in a manner similar to the last SQL it.

  the problem is that if I do it according to the foregoing, I add a redundant node artificially.  the first node < x_data > is not necessary, but how can I go and add the xmltype column to the result without having to qualify it with another element around it?

  know how to do the following:

  < outerelement > < itemID > 1 < / itemID > < x_data dummyattr = "1" >

  < item > blah < / item >

  < element > more blah < / item >

  < / x_data > < / outerelement >

  ?

  Too bad... I had a moment mute:

  Select xmlelement ("outerelement"

  xmlelement ("itemID", item_id)

  x_data

  )
