• XDB. XMLIndex problem and table (XMLSEQUENCE (EXTRACT (xmltype, path))

  Hello
  I have a database of Oracle 11 g Release 11.1.0.6.0 - 64 bit Production With the Real Application Clusters option.
  
  I feel something strange with an XMLType column.
  I have a table configurator.t_vehicle_configuration (id_vehicle x_configuration NUMBER, XMLType).
  x_configuration is unstructured.
  
  I created an index on the field of xml in this way:
  
  CREATE INDEX idx_vehicle_configuration ON configurator.t_vehicle_configuration (x_configuration) INDEXTYPE IS XDB. XMLIndex;
  
  Then I have a package implementing a function that count nodes in the xml field and its return values
  
  This does not (return 0 instead of 1):
  

      SELECT count(*)
        INTO count_
        FROM configurator.v_vehicle_configuration vc,
             table(XMLSEQUENCE(EXTRACT(vc.x_configuration, '/vehicleconf/GeoFence/spaceTarget[@id="'||in_id_space_target||'"]/user[@id="'||in_id_user||'"]/alarmwhen'))) p
       WHERE vc.id_vehicle = in_id_vehicle;
      
      RETURN count_;

  This mode of operation (return 1):
  

      str_ := '/vehicleconf/GeoFence/spaceTarget[@id="'||in_id_space_target||'"]/user[@id="'||in_id_user||'"]/alarmwhen';
  
      SELECT count(*)
        INTO count_
        FROM configurator.v_vehicle_configuration vc,
             table(XMLSEQUENCE(EXTRACT(vc.x_configuration,str_))) p
       WHERE vc.id_vehicle = in_id_vehicle;
      
      RETURN count_;

  As this mode of operation:
  

      SELECT /*+ NO_XMLINDEX_REWRITE */ count(*)
        INTO count_
        FROM configurator.v_vehicle_configuration vc,
             table(XMLSEQUENCE(EXTRACT(vc.x_configuration, '/vehicleconf/GeoFence/spaceTarget[@id="'||in_id_space_target||'"]/user[@id="'||in_id_user||'"]/alarmwhen'))) p
       WHERE vc.id_vehicle = in_id_vehicle;
      
      RETURN count_;

  And also this way it works:
  

      SELECT count(*)
        INTO count_
        FROM configurator.v_vehicle_configuration vc,
             table(XMLSEQUENCE(EXTRACT(vc.x_configuration, '/vehicleconf/GeoFence/spaceTarget[@id="228"]/user[@id="49"]/alarmwhen'))) p
       WHERE vc.id_vehicle = in_id_vehicle;
      
      RETURN count_;

  I sailed a bit on the internet but I have found no help for my problem...
  I guess that's something concerning the substitution on the fly of the variables, which does not work with an index.
  Do you have any suggestions?
  Is there a way that will prevent the rewriting of all the functions?
  
  Thanks in advance

  First

  On 11.1.0.6.0 Please do not use table (xmlsequence (extract ())) Please use the SQL/XML standard XMLTAble operator...

  SELECT COUNT(*)
     INTO count_
    FROM configurator.v_vehicle_configuration vc,
             XMLTABLE
            (
                '$XML/vehicleconf/GeoFence/spaceTarget[@id=$ID_SPACE_TARGET]/user[@id=$ID_USER]/alarmwhen'
                passing vc.x_configuration as "XML",  in_id_space_target as "ID_SPACE_TARGET",  in_id_user as "ID_USER"
             )
       WHERE vc.id_vehicle = in_id_vehicle;
  
      RETURN count_;
  

  2. never generate XPATH strings dynamically (Note XMLTABLE simply will not allow it). It is almost impossible to optimize since in the case escalated, the query may be a function of the processing line, and it leaves the vulnerable application WHO the problems of injection. Earlier versions of XML DB supported the use of string concatenation technique to provide the value of predicate as a method of implementation of the bind variable, but from what I remember, this is only implemented and tested for storage relatiion object. Even when workng with storage relational object this technique should not be used in the development of new code n a 10.2.x post database. As far as I know this was not implemented for binary XML / XML INdex since the implementations of XMLQUERY, XMLTable and XMLEXists provided a much more robust implementation and standardized to link the underlying values at query runtime

  If you do not know the XPATH expression until run time please build the complete SQL statement dynamically and run it via EXECUTE IMMEDIATE or DBMS_SQL, then pay attention to injection vunerabilities in your application.

  The fact that you get different results seems to be the result of the previous method of binding of predicates works do not correctly with the XML Index. If the solution I gave above does not work, please fill out a bug and that we can continue the investigation

• XMLTable performance vs TABLE (XMLSequence ())

  Hello world
  
  I encountered a problem which I hope I can find help with.
  
  He has a task to analyze a large XML text (~ 15 MB) and update a table based on it. So I created a procedure that takes a parameter of XMLType and does the job. Pretty simple. However, the thing is that if I use XMLTable, which is the preferred method to parse the XML, it runs for hours. Once I replace XMLTable with the method TABLE (XMLSequence ()), the procedure ends in less than two minutes on the same machine. Seems very strange to me.
  
  Any ideas what could be the cause of such a poor performance from XMLTable?

  Because you have them different tasks. With the XML Table, you create a game via the return of intermediate results. Why not use the same approach to Table (XMLSequence ()) as in

      select
        ap.member_id,
        ap.point_id,
        ap.country_numeric,
        ap.place,
        ap.name,
        ap.currencies,
        ap.address,
        ap.contact,
        ap.contact_phone,
        ap.details,
        to_date(ap.enabled_date, 'DD.MM.YYYY'),
        ap.works
      from
        xmltable('/document/directory/reply[@type=''Points'']/data/row'
          passing p_Points
          columns
            member_id int path 'column[@col="1"]/@value',
            point_id int path 'column[@col="2"]/@value',
            country_numeric character(3) path 'column[@col="3"]/@value',
            place national character varying(50) path 'column[@col="4"]/@value',
            name national character varying(255) path 'column[@col="5"]/@value',
            currencies national character varying(255) path 'column[@col="6"]/@value',
            address national character varying(255) path 'column[@col="7"]/@value',
            contact national character varying(40) path 'column[@col="8"]/@value',
            contact_phone national character varying(40) path 'column[@col="9"]/@value',
            details national character varying(255) path 'column[@col="10"]/@value',
            enabled_date character(10) path 'column[@col="11"]/@value',
            works national character varying(255) path 'column[@col="12"]/@value') ap;
  

  I hope it works now as fast as the old method, but you will need to provide the statistics on that. I'm interested to see the moment of execution.

  Now if you want it to run faster, then

  CREATE TABLE xml_hold (xml_col xmltype);  -- can be a global temporary table if you desire
  

  and in your code

  INSERT INTO xml_hold VALUES (p_points);
  

  then change select it above to

      from xml_hold xh
        xmltable('/document/directory/reply[@type=''Points'']/data/row'
          passing xh.xml_col
  

  This works because the default storage for XMLType columns in 11.2.0.2 was replaced by SECUREFILE XML BINARY. When you store XML in this column, Oracle preprocesses the XML file and stores the data in a binary format that is more effective to deal with. You can read about that in the Oracle documentation if you wish. Even with the charge to convert the XML into an internal format, the whole processing time should be faster given the application can now run much more efficiently.

• Download massive updated the planned orders in table msc_supplies

  Hi all

  I need your suggestion below requirement:

  For item RM, we planned order suggested that the CPHA; before releasing it, we want to change Date of implementation and the amount of order, then output the last modified scheduled released automatically to create the PR in purchases & Payables.

  In order to change the planned orders of RM, we export order planned the Workbench of the CPSA in the worksheet and then change dates, quantity, etc. in the worksheet. We want this change data to insert in the table msc_supplies automatically with manually intervene them and followed by releasing these planned automatically orders to create a PR

  We want to know how to achieve this requirement. We want to know the available custom hook and script to insert record in to msc_supplies.

  Have a great day.

  Thank you

  Sanngo

  Hello

  We expect steps below:

  (1) export the planned RM command suggested by the CPSA to the spreadsheet or report.

  (2) prepare the csv file with mandorty field as shown below in the table, i.e. date, quantity, etc. and format the data according to the custom intermediate table created.

  (3) custom concurrent requests created, which is used to locate the data file and upload the data to a custom intermediate table.

  (4) of the intermediate table that we are download the same data in the database MSC_SUPPLIES table (make a validation here check) in the same program. After that a manually scheduled commands added to the table of MSC_Supplies and can be found in the CPSA workbench.

  (4) in the same concurrent application of custom, call "automatic rejection" to release these records of the base table of msc_supplies, where release_flag a value of 1.

  We want to know the required fields need to be updated in the staging table custom and the base table:

  ORGANIZATION_CODE ORGANIZATION_ID

  ITEM_SEGMENTS INVENTORY_ITEM_ID

  ORDER_TYPE_TEXT ORDER_TYPE (5)

  New Date FIRM_DATE

  New quantity FIRM_QUANTITY

  Argument Plan_ID

  Transaction_id

  RELEASE_STATUS (1)

  SR_INSTANCE_ID

  You can test adding the manually planned adhoc decrees on Workbench CAWC namely, which are updating fields in the MSC_SUPPLIES table.

  Have a great day.

• Adding field in the item table programmatically

  Hello.

  I'm doing a generic 'engine' for generating test reports/certificates.

  I made a custom data containing type report item, I used to do a local variables array of report called table of report item items.

  The data type contains generic areas (chain of title elements, a string of type item, etc.) and a container of the element data.

  The idea is to increment the array of items to report with report items and then fill the data container of the element with the fields of for example a Table element container.

  Either that, or just add a field in the report item with the data Table element type.

  But I can't find a way to add fields programmatically in a container.

  Anyone know if this is even possible?

  Found!

  Using from one stage of education, who points to the array of report items using the NewSubProperty method.

  Finished with the following statement:

  Parameters.Report_Element_Array.InsertElements (GetNumElements (Parameters.Report_Element_Array), 1, 0),
  Parameters.Report_Element_Array [GetNumElements (Parameters.Report_Element_Array)-1]. NewSubProperty("Element_Data",PropValType_NamedType,False,"NSE_Report_Table",0)
  
  

• Update on the table by extracting the data from the table even under certain conditions

  Hi Experts,

  3 3 APRIL DEV 98 Y IND123 ABC

  CONDITION: I need to take lines which has the minimum BATCH_NO for each of the EMP_SYS

  for example,.

  1 FEBRUARY 10 PROD 84 Y IND123 ABC

  DEV 1-23 APRIL 98 Y IND123 ABC

  For the above two lines, I need to update the status of DEF. How to select this criterion and update in the same query?

  Currently, I used the query to select the minimum BATCH_NO for each of the EMP_SYS below.

  SELECT EMP_SYS, BATCH_NO, JOIN_DATE, FLAG, LOGIN_ID, STATUS

  Of

  EMP_SYS, BATCH_NO, JOIN_DATE, FLAG, LOGIN_ID, STATUS, SELECT ROW_NUMBER)

  COURSE NR (PARTITION BY ORDER OF EMP_SYS OF EMP_SYS)

  FROM EMP

  WHEN STATUS = 'ABC' AND FLAG = "Y".

  )

  WHERE

  NR = 1;

  If I try to use the update on the above query statement... It updates every 6 rows instead of 2 rows.

  Please suggest me a way to update only the two lines that has the minimum BATCH_NO for each of the EMP_SYS.

  But is possible to write the query without using the Group of?

  Update e EMP

  set STATUS = "DEF".

  where BATCH_NO = (select min (BATCH_NO) from EMP I where STATUS = 'ABC' AND FLAG = 'Y' and i.emp_sys = e.emp_sys)

  And my another problem here... I don't know why my first clue didn't work...

  Probably the syntax. The main indicator uses parentheses, as

  /*+
  select /*+ leading(table1, table2) */ *
    from table1, table2
  */
  

  Remember that you must use the table alias name in tips for the identifier to be recognized

  You can also consider using the y indicator (if you must use a hint) for several tables - beware, it is MUCH easier to do worse performance with this suspicion using the order of the tables in the FROM clause in left to right

  /*+
  select /*+  ordered */ *
    from table1, table2, table3
  . . .
  */
  

  How I create index will affect how it works?

  How the index was created probably won't affect how it works. Indexes can be created using constraints and directly with the CREATE INDEX command. The creation of the index should not be as important as its defined characteristics: index type, columns, etc.

• Values in the list by the order of table in SELECT Union

  Version: 11.2
  
  Apparently a very basic thing. But I couldn't do it :)
  
  In the UNION example below automatic sorting in is based on alphabetical order. I want to get rid of this sort and list the values according to the order of the table in the SELECT.
  
  Test data

  create table test1 (name1 varchar2(10));
  
  create table test2 (name2 varchar2(10));
  
  create table test3 (name3 varchar2(10));
  
  
  insert into test1 values ('EARTH');
  insert into test1 values ('TAURUS');
  insert into test2 values ('YELLOW');
  
  insert into test2 values ('ALPHA');
  insert into test2 values ('TANGO');
  
  
  insert into test3 values ('BRAVO');
  
  
  select name1 from test1
  union
  select name2 from test2
  union
  select name3 from test3;
  
  NAME1
  ----------
  ALPHA
  BRAVO
  EARTH
  TANGO
  TAURUS
  YELLOW
  
  6 rows selected.

  In the above example, I want the values in the first array SELECT listed first, then all the values of the second table in SELECT it and so on.
  
  Basically my requirement will be
  

  Return all values from test1 (alphabetically sorted)
  then
  Return all values from test2 (alphabetically sorted)
  then
  Return all values from test3 (alphabetically sorted)

  Expected results:

  NAME1
  ----------
  EARTH  ------------> from the first table in the SELECT
  TAURUS ------------> from the first table in the SELECT
  ALPHA  ----------------------> from the second table in the SELECT
  TANGO  ----------------------> from the second table in the SELECT
  YELLOW ----------------------> from the second table in the SELECT
  BRAVO  ------------------------------> from the third table in the SELECT

  Hello

  Union made a distinct in terms of the line. From the line "ALPHA", 2 and the line 'ALPHA', 3 are different, they both show in the result set.

  Further, you are all just lucky, that you get the results you want with the order clause:

  order by 2
  

  This performs a sort on the second column (1,2,3)
  Also, you want to sort on the first column (name1, name2 and Name3). The order clause should be (as already shown correctly abbove):

  order by
    2, 1
  

  Kind regards

  Is it possible to use the table headers as the control of the ORDER BY in the SQL query?

  You can, but I think it's generally easier to use table sort client-side. It is much faster and easier to implement. Just get kind of table to the client side. Here is an example.

• single output item table

  I'm a picture fill successfully and now in train to go through each element and output of my VI.

  

  The problem I have is the for loop goes through without sending the value to my indicator. I flipped through all the options of tunnel and placed the marker inside the loop for. From my experience in programming, my logic seems solid. To finish > element in process > element Output > loop iteration until the condition is met. What is the missing piece that I can't translate into Labview code? Thank you.

  HI amacapa,

  you always miss the concept of stream...

  When FilteredOutput is an output of your VI you will always produce just a scalar value - after that the whole VI was executed!

• Channel separation order waveform table parametricaly?

  Hello.

  I have an application where I gain two temperature & strain. The number of each type of sensors varies from one test to the other. I want graphic of each type on different graphics so that I can scale properly. I enclose a picture of my application.

  Is it possible to control through front?

  Say, using a digital command to set the number of strain gauges (first N channels are strain gauges, thermocouples of rest), then separate the data.

  Thank you

  Hi user,

  You can use the function split array.

• ExtractValue, extracted, xmlsequence

  for example, if the first row not contained that single product/Notebook (as the second row) there is need to use TABLE (XMLSEQUENCE...), right? Only extractvalue (demo_field, "Product/Notebook/@Brand") would suffice, right? xmlsequence is necessary because the first line has several entrances laptop and all these multiple information is always returned as a bunch of items for laptop (knots?) instead of relational lines, is that correct? then xmlsequence comes into play in order to convert every book of this bunch of laptops in topics separated more later converted into relational lines by SCOREBOARD operator. is it more correct?

  Thank you

  Yep, that sounds about right.

  With XMLTABLE, it would be something like this...

• 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!
