• Ask the CLOB column (with XML content)

  1. how to extract a particular xml tag value for a column with the CLOB data type.

  Example:

  < REQUEST_DETAIL >

  PR < GROUP_TYPE > < / GROUP_TYPE >

  < GroupName > ASSET MANAGEMENT TECHNICAL DATA < / GroupName >

  < BUS_UNIT_ACRN > SCS-FCAT < / BUS_UNIT_ACRN >

  < PROJ_MGR_ID > < / PROJ_MGR_ID >

  < / REQUEST_DETAIL >

  Select

  XmlType (provable). Extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal)

  e t

  /

  example above works.

  If I do not know the order of xml tag to ask how can I get the value.

  (/ * * / / * * / REQUEST_DETAIL/GROUP_TYPE / * / *)

  2 using the DBMS_LOB. SUBSTR takes longer to run and it never returns results and session will wait status for access to LOB_INDEX content (at the same time the CLOB column is used by the application).

  Y at - it another option for faster results.

  SELECT DBMS_LOB. SUBSTR (xml_blob, 4, DBMS_LOB.) INSTR (xml_blob, "< name >", 1, 1) + 6) name.

• CLOB in XML a better approach normal table?

  Hello
  
  Requirements:
  (1) I have a table that has records of 15 m and each record have a XML stored in a CLOB format (each xml is AVG 25 KB).
  (2) information in this table should be used for reporting the end (currently no OLAP structure).
  3) there are many areas in XML that is not necessary to run queries.
  (4) we intend to extract necessary fields from XML and then store them in the normal table format to make quick and simple queries (should store us as XML).
  (5) how should I proceed with this. I've not used XML in the past.
  
  Currently, we give xml data to the Java application as a batch and then Java application is extract necessary fields and then store them in the final table. What is the best with regard to the performance of the migration also? Should I convert CLOB in XML and stored in the staging of the table and then select the required fields of staging table using XML DB and then load in the final table?
  
  The main purpose is quick retrivel of the final table.
  
  Thank you.

  Typos corrected

  Hello

  I would say that approach 2, with a table binary XMLType.

  For example, suppose that the source table is TEMP_XML_CLOB and contains this structure XML documents in the donnees_xml (CLOB) column:

  
   
  
    1
    TEST 1
   
   
    
     A1234-B
     2
    
    
     Z5554-E
     7
    
    
     B1234-A
     1
    
   
  
  

  (1) first create the table XMLType:

  create table temp_xml_binary of xmltype
  xmltype store as securefile binary xml
  ;
  

  (2) the source table bulk insert:

  insert into temp_xml_binary (object_value)
  select /*+ append */
         xmltype(xml_data)
  from temp_xml_clob
  ;
  
  commit;
  

  (3) question the XML as relational data:

  SQL> select x1.id
    2       , x1.description
    3       , x2.item_id
    4       , x2.item_type
    5       , x2.quantity
    6  from temp_xml_binary t
    7     , xmltable(
    8         xmlnamespaces(default 'example.oracle.com')
    9       , '/root'
   10         passing t.object_value
   11         columns id          number       path 'header/id'
   12               , description varchar2(80) path 'header/des'
   13               , items       xmltype      path 'items'
   14       ) x1
   15     , xmltable(
   16         xmlnamespaces(default 'example.oracle.com')
   17       , '/items/item'

   22       ) x2
   23  ;
  
          ID DESCRIPTION           ITEM_ID                        ITEM_TYPE   QUANTITY
  ---------- --------------------- ------------------------------ --------- ----------
           1 TEST 1                A1234-B                        A1                 2
           1 TEST 1                Z5554-E                        B1                 7
           1 TEST 1                B1234-A                        A1                 1
   
  

  If you encounter some performance issues with this method, you can also try to create an additional index of XML structured:

• Insertion XMLAgg large output in a table with a CLOB column

  Hello
  
  I need to fill a CLOB column in a table with the output of a query select using XMLAgg which returns a string length exceeds the maximum length of the SQL 32767octets.
  
  The table I ask has 300,000 lines I need to create an XML file. When I apply the query below (without XMLAgg) I get 300 000 lines that each of the 134 characters each. However, when I add the XMLAgg I can't select the results as XMLAgg concatenates my 300,000 lines in a single line, where a length of string is too long for SQL.
  
  SELECT (XMLElement ("line", XMLELEMENT ('cell', XMLATTRIBUTES ('XML_TAG_1' "colName"), attribute1)
  XMLELEMENT ('cell', XMLATTRIBUTES ('XML_TAG_2' "colName"), attribut2)
  XMLELEMENT ('cell', XMLATTRIBUTES ('XML_TAG_3' "colName"), attribut3))
  )
  of XML_TAGS_TABLE
  -Produces 300,000 lines like below
  < row > < cell colName = "XML_TAG_1" > 12345 < / cell > < cell colName = "XML_TAG_2" > abcdef < / cell > < cell colName = "XML_TAG_3" > 123xyz < / cell > < / row >
  
  With this in mind, I created a temporary table (TEMP_TAB_TEST) with a column called XML_ROW that is a CLOB. Applying XMLAgg in the above query, I would get 300,000 lines concatenated into a string. I need to get the single string output in the XML_ROW (CLOB) column XMLAgg while I can then convert them to the XML file.
  
  I don't see how I can use XMLAgg due to the length of the output it produces? Is there a way I can fill the column clob using the XMLAgg is the result of a PL/SQL package / block Anon?
  
  Thank you very much
  Simon.

  It works for me:

  CREATE TABLE TESTCLOB (ID NUMBER, DATA CLOB);
  
  insert into testclob (
    id,
    data
  ) values (
    1,
    (SELECT XMLTYPE.getClobVal(XMLAGG( XMLElement("row", XMLELEMENT("cell", XMLATTRIBUTES('XML_TAG_1' COL1),attribute1)

  After you import your csv file just change the length CHAR (100000).

  ex: your column col1 CHAR (1000) to change CHAR (100000).

  and deploy your mapping and execution

• Audting CLOB column

  Hi all

  DB version: Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production (PL/SQL Release 11.2.0.4.0 - Production)

  Brief Description: column CLOB audit until anonymous PLSQL block but does not update an external application (such as a web application).

  More in detail, we have a base with a CLOB column table and an audit table that captures any change on the base table using a trigger of DB.

  Table audit this as below:

  ID	NOT NULL NUMBER (38)
  COMPONENT_KEY	THE NUMBER OF NON-NULL
  CHANGEDCOLUMNNAME	VARCHAR2 (30)
  CHANGEDBY	VARCHAR2 (20)
  CHANGEDDATE	DATE
  BEFORECHANGE	CLOB
  EVENT	CLO

  We observe that the audit works perfectly fine if we update the prompt SQL CLOB column. But when the column is updated. a web UI - the trigger retrieves the value of

  :OLD.CLOB_COLUMN 
  

  and reads an empty clob

  :NEW.CLOB_COLUMN
  

  .

  Possible explanation: read in-depth, including that CLOB actuallly stores the reference to memory location & database manages insertions/changes effectively CLOB columns by first introducing an EMPTY_CLOB and then subsequently using DBMS_LOB. Write() for transmitting the content of CLOB to the location of the DB. DB trigger seems to be pulled between the insert EMPTY_CLOB & the DBMS_LOB. Write() and accordingly, we find that: NEW. CLOB_COLUMN to be EMPTY_CLOB.

  The above explanation makes sense? If so, why does it work correctly from the SQL prompt? Can we not check a DB trigger CLOB columns at all?

  Thank you

  Srini

  On additional debugging, it seems not to be a problem with the database. She seems to be the implementation of JDBC for CLOB data types - where it is a 2-step process

  STEP 1 - Insert EMPTY_CLOB

  STEP 2 - lock the line & enter the stream to broadcast content to CLOB CLOB.

  Given that triggers executed immediately after STEP 1 - the NEW value is EMPTY. Here, the concepts of database are intact. In this case, the check must arrive at the JDBC layer.

  The maximum size of a column report CLOB value is 32 KB. However, the maximum size for the content of the line of the full report is also 32 KB (including the HTML markup), so you can be hitting this limit because of the size of your 10 K CLOB data + the rest of the line.

  According to the database character set and the characters which that contains data, the character encoding may use more than one byte to represent a character.

• Getting string of a CLOB column

  Hi team,

  I have a problem. as if I had the table that contains a CLOB column. Since I need to extract exactly a word string. I'll give an example on how it will be below.

  Let T_OBJ of Table has a WORK_LOG column that is a CLOB.

  The CLOB data is huge, but since I need to extract a string, containing the name that falls exactly after a WORD

  Create table T_OBJ (SNO number, WORK_LOG clob);

  Insert into T_OBJ values (1, '1263636000 AR_ESCALATOR. amended by XXXXXXXXX XXXX ("This is Auto Closed.Change was closed")

  How is the sample data. But what I found most is there are the delimiters in the text. A delimiter is exactly after name i.e. XXXXXXXX XXXX (delimiter)

  My output should be one name i.e. XXXXXXXX XXXX, which falls immediately after the text "modified by".

  I tried like this

  Select dbms_lob.substr (WORK_LOG, 50, dbms_lob.instr (WORK_LOG, "modified by"))

  of T_OBJ;

  Can someone help me please. I'm using ORACLE 11 g.

  Hello

  Check if the query below matches your needs.

  SELECT dbms_lob.substr(WORK_LOG
                        ,((dbms_lob.instr(WORK_LOG,'.',dbms_lob.instr(WORK_LOG,'Modified By ')))-    --- get position of DELIMITER AFTER MODIFIED BY
                         (dbms_lob.instr(WORK_LOG,'Modified By ')+length('Modified By ')))           --- get position of MODIFIED BY
                        ,dbms_lob.instr(WORK_LOG,'Modified By ')+length('Modified By '))             --- get position of MODIFIED BY
  FROM t_obj;
  

• Read CLOB column - by bursting

  I have two tables File_Master and File_Detail
  Primary key File_Master FILE_ID
  Primary key File_Detail FILE_ID, LINE_ID
  
  I have a CLOB FILE_CONTENT column table File_Master.
  For each record FILE_ID in File_Master, hundreds of lines are stored in the CLOB column.
  
  I want to read this 'File_Content' CLOB column and and break each line (1000 characters)
  by pieces to fill the columns in File_Detail.
  
  Since there will be thousands of lines in the process, what would be the best approach when writing PL/SQL code for better performance?
  
  Thanks in advance.

  Do you want real lines (completed by a Unix or DOS line break) of the CLOB?

  I use the following function to process the lines of CLOB (then tokenising and analysis of each line):

  create or replace type TStrings is table of varchar2(4000);
  /
  
  create or replace function ClobToLines( c clob, lineTerminator varchar2 default null  ) return TStrings pipelined is
  -- function:    CLOB TO LINES
  -- descr:       reads lines from a clob and returns each line as a separate row
  
          pos     integer;
          line    varchar2(4000);
          offset  integer := 1;
          charSep varchar2(10);
          amount  integer := 1;
  begin
          -- if no CRLF specified, detect whether DOS or Unix linefeeds are used
          if lineTerminator is null then
                  pos := DBMS_LOB.InStr( c, chr(10), offset, 1 );
  
                  if pos = 0 then
                          raise_application_error(
                                  -20001,
                                  'The CLOB does not contain char #10 (used by both DOS and Unix linefeeds) and failed to parse.'
                          );
                  end if;
  
                  if pos > 1 then
                          DBMS_LOB.Read(
                                  lob_loc => c,
                                  amount => amount,
                                  offset => pos-1,
                                  buffer => charSep

                  if charSep = chr(13) then
                          charSep := chr(13)||chr(10);
                  else
                          charSep := chr(10);
                  end if;
          else
                  charSep := lineTerminator;
          end if; 
  
          while (offset < DBMS_LOB.GetLength(c) )  loop
                  pos := DBMS_LOB.InStr( c, charSep, offset, 1 );

• How to view the report on one Clob column online?

  Hello
  
  In a set of columns in the report created with the wizard to create a Page, a Clob column is made that resembles a dozen lines high. The other elements are the high standard of a line. How can I load Apex to restore the Clob, the same height as the other columns (on one line)? Left like that, I'll only be able to see 2 or 3 lines at once, even if there is very little data in Clob columns.
  
  I would have attached a screenshot, but I do not see this feature on the forum site.
  
  BTW, I guess this is a common newbie question. I don't see an answer in the Forum or in the documentation. Your response is appreciated.
  
  Thank you
  Kim

  Unfortunately, at this stage of my Apex maturity, it would be very difficult for me to reproduce the problem on apex.oracle.com (don't laugh, Jedi are not built in a day).

  It's very simple.

  1. sign up for an account on apex.oracle.com.
  2. in your local installation of the APEX, go to SQL Workshop > utilities > generate DDL. Click create a Script and use the wizard to generate a DDL script that contains the objects of database required by your application. (You can find out what they use Application Builder > Application > utilities > database object dependencies.)
  3. your local installation of APEX export demand.
  4. download and run the DDL file on apex.oracle.com using SQL Workshop > Scripts SQL.
  5 import the request to apex.oracle.com.

  So I resort to ad a page to SkyDrive. When you see the picture, the question will be very clear and I guess that there is a way to dusty solution tucked away in the vault. Note: I would like to limit the height of the text element, not the width of it. Here's the URL for the screenshot.

  Go to the Notes column attributes. Define the number of rows to 1 and the attributes of the element to

  style="height: 1.3em;"
  

  You may need to adjust the height to match other items. (Or according to browser [s], may not need any: in Firefox on Windows 7 14 "number of lines: 1" seems to mean "number of rows: 2". ") (Go figure.)
