• How to find special cases in XML in the situation of overflow

  Hello
  
  I have a XML with repetitive data. I have a requirement to indicate the particular case of the data. For example, I should display DailyBenefitAmount of second instance, which is from 150.00 as in the example of XML code below.
  
  I read in Documaker documentation indicating it can be mapped to XDD and with the syntax below to find the instance.
  Syntax:? ("XDD_NAME", #instance)
  
  So I mapped my XML to XDD like? ("DailyBenefitAmount") and I used the? ("DailyBenefitAmount", 2) in my DAL script, but no luck and it does not work.
  
  Can someone shed some light, how to handle this requirement.
  
  Example of XML
  
  < id rider = "Rider_1" >
  < RiderCode > END < / RiderCode >
  < DailyBenefitAmount > 75.00 < / DailyBenefitAmount >
  < BenefitCode > ALF < / BenefitCode >
  < ModalPremAmt > 65.15 < / ModalPremAmt >
  < / rider >
  < id rider = "Rider_1" >
  < RiderCode > END < / RiderCode >
  * < DailyBenefitAmount > 150.00 < / DailyBenefitAmount > *.
  < BenefitCode > ALT < / BenefitCode >
  < ModalPremAmt > 65.15 < / ModalPremAmt >
  < / rider >
  < id rider = "Rider_1" >
  < RiderCode > END < / RiderCode >
  < DailyBenefitAmount > 300,00 < / DailyBenefitAmount >
  < BenefitCode > NHC < / BenefitCode >
  < ModalPremAmt > 65.15 < / ModalPremAmt >
  < / rider >

  XML Xpath statements can be tricky trying to cope with events. In your example where you might think this as the second occurrence of DailyBenefitAmount , it's really the 'first' DailyBenefitAmount of the second occurrence of Rider I think you want. Therefore, the Xpath statement is more like this:

  Jumper [2] / DailyBenefitAmount

  Now, you probably don't want to have a specific XPath statement by event, you may want to recover. For the presence to apply to an appropriate level, you must be able to be able to specify where the accident should be applied within the XPath expression. This is accomplished by using * inside the brackets.

  Rider [*] / DailyBenefitAmount

  When XPath is executed, the value of instance substitute in the desired node level and return the appropriate value.

• How to find AUTO_SAMPLE_SIZE set at the DB level?

  Version: 11.2.0.4

  OS: RHEL 6.4

  We use below collect stats procedure for gathering statistics for our tables.

  exec dbms_stats.gather_table_stats (-)

  ownname = > 'QMP, -.

  tabname = > 'HRTB_MASTER ', -.

  estimate_percent = > DBMS_STATS. AUTO_SAMPLE_SIZE, -.

  Cascade = > TRUE;

  method_opt = > 'for all THE COLUMNS of SIZE AUTO '.

  );

  We use a custom procedure that runs dbms_stats.gather_table_stats for the selected tables.

  Lately that gather employment stats took longer. When we checked DBA_TABLES. SAMPLE_SIZE these tables, we noticed that it is 100%. That is to say Oracle is 100% sampling.

  We thought that DBMS_STATS. AUTO_SAMPLE_SIZE was 10%, by default. How can I determine DBMS_STATS. AUTO_SAMPLE_SIZE currently set at the level of the DB? Google search did not help

  It's a shame the manuals do not tell you anything on the algorithm and particularly the effect of the global preference APPROXIMATE_NDV setting to true.

  Check the result of:

  Select dbms_stats.get_prefs ('approximate_ndv') of double;

  If the result is "true" then you have activated the mechanism of approximate_ndv for the collection of statistics on the table and Oracle will use 100% the size of the sample of auto. The advantage of this is that is don't do massive unique on each column to get the num_distinct, and it will get the correct answer to about 1.5% in time to make a small percentage using the older mechanism. If this is the case in your system, as has been pointed out by Stefan, the extra time can result from several work to calculate a number accumulated histograms; It can also disappear for large sample sizes used for indexes more.  NOTE: even with auto to 100% on the table with approximate_ndv, histograms, and index, always use the same sample old 'auto '.

  Here is a link that will take you to a whitepaper on the subject if you are interested: https://jonathanlewis.wordpress.com/2009/03/20/hotsos-2009/

  There are some side effects, however, which could have a significant impact on a few unfortunate, for example: https://jonathanlewis.wordpress.com/2014/03/02/auto-sample-size/

  It depends on what you expect. If you issue count (*) you ask Oracle "how many lines there. If you issue a County () you ask Oracle 'how non null values for are there. "

  delete from 
  where  is null;
  

  Ideally you would simply place a NOT NULL constraint on the column in question, thus prohibiting NULL values into the system (assuming that your business needs, it is that the column MUST always have a value).

• How do find no data in the table

  Hi all
  
  I have 250 table in my diagram and when I query like this
  
  Select * from object where type_objet = 'TABLE' and owner = 'MATTELLI.
  order by object_name CSA
  
  
  Some tables have no data in it. How to find the tables that not have data or records
  
  Thanks and greetings
  Srikkanth.M

  Hi Srikkanth,

  First of all, if you are only interested in object TABLE type, so you should better use dba_tables instead of dba_objects.
  Then, assuming that your statistics are up to date, it would look like:

  SELECT *
    FROM all_tables
   WHERE owner = 'MATTELLI'
    AND num_rows > 0
   ORDER BY table_name ASC
  

  Otherwise, you can go with a subquery and a 'select count.

• How to delete several lines in the details Table with PRIMARY KEY = ("VID", "LINEITEM")?

  Mr President

  My worm Jdev is 12.2.1.

  I have master tables / details.

  I have 2 lines for each PRIMARY KEY = ("VID", "LINEITEM") as below in the Details table.

  

  Please help how to get a button on a jsf page to remove these two lines at a time.

  Concerning

  So, in your app (data model) module, you have a master relationship / typical retail:

  

  And the relationship between them is based on some ViewLink

  Now go to the ViewLink, relationship, accessor.

  Take a look at the Destination accessor.

  Generate accessor object to check and give a name Acessor

  

  Then go to the master VO, Java and Include accessor, the class generate a display line:

  

  Go to the class view Java generated line, you'll find a method with the name of the accessor of the previous step, in the form of:

  public RowIterator getYourDetails...or_whaterever_IsAccessorName..() {
  }
  

  Now, in the same Java class, write the following Java method:

  public void removeDetails(){
    RowIterator details = getYourDetails...or_whaterever_IsAccessorName..(); // it is RowIterator over all details
    Row r = details.first();
    while (r != null) {
        r.remove();
        r = details.next();
    }
  }

• How to update or insert for the fa_distribution_history table?

  I need to change the location of an asset code when it changes its physical location. I looked in the tables and this change of assignment / location change updates and inserts a record in the fa_distribution_history table. I looked at a few documents, and there is a package called fa_distribution_history_pkg with the Update and Insert methods.
  The question I have is changing the assignment, that I have to update the record of the old assignment and then create one with the new assignment?
  Please let me know how I should proceed.
  Thank you.

  Hello.

  You should not use the package "fa_distribution_history_pkg" directly from your custom code.

  The ideal way is to use the public APIs provided by Oracle. In this case, you should use is FA_TRANSFER_PUB.do_transfer.

  Please try this one and advise if you are having trouble.

  See you soon

• How to do a subquery in the same table?

  I'm trying to figure out how to query inside a query...?
  
  Here is my table:
  
  NAME ID (PK)
  
  My problem is when someone creates a new line in this table, the system creates other lines associated in the same table, but it fits the ID of the line of "parent" in the name of the new colums.
  
  For example:
  
  1001 BOB_ADDRESS
  1002 FRED_ADDRESS
  1003 NEW_ROW_1001_BOB_ADDRESS
  1004 NEW_ROW1_1001_BOB_ADDRESS
  1005 NEW_ROW_1002_FRED_ADDRESS
  1006 NEW_ROW1_1002_FRED_ADDRESS
  
  
  What I want is a query that would work to something like:
  
  SELECT ID, NAME
  FROM TABLENAME,
  BY NAME;
  
  But this query finds all rows of the child >
  
  For example:
  
  ID NAME
  ---- ---------------------------------------
  1001 BOB_ADDRESS
  1003 NEW_ROW_1001_BOB_ADDRESS
  1004 NEW_ROW1_1001_BOB_ADDRESS
  1002 FRED_ADDRESS
  1005 NEW_ROW_1002_FRED_ADDRESS
  1006 NEW_ROW1_1002_FRED_ADDRESS
  1010 JOE_ADDRESS
  1100 NEW_ROW_1010_JOE_ADDRESS
  1117 NEW_ROW1_1010_JOE_ADDRESS
  
  Any thoughts?

• How to create a view in the DB table for some servers

  Hello
  
  We need create a country table which will contain data for countries.
  
  I want to create it in such a way that it will be common for all servers - but as a point of view. not the real table, only the data and views do not change.
  
  How can I do?
  
  Thanks in advance

  Are you sure you want to say 'tablespace '? A tablespace is a collection of data files. It has nothing to do with the privileges of the object, object namespaces, etc. I'm guessing that you mean that you have two schemas, OBITUARIESCS and ADVERTISEMENTCS. A schema is a collection of objects of database belonged to a particular user. A single table can exist in spaces of multiple tables (assuming it is partitioned). Different schemas can have an infinite number of tables with the same name in the same table. The database schema is the namespace for objects such as tables.

  Assuming that you have two schemas in your database, you can create a table of COUNTRIES in the OBITUARIESCS schema. You can then grant SELECT access on the table to another user, ADVERTISEMENTCS, i.e.

  GRANT SELECT ON country TO advertisementcs
  

  You can then ask questions (but not change) the COUNTRY code of the property of ADVERTISEMENTCS table

  SELECT *
    FROM advertisementcs.country
  

  If you want to be able to remove the prefix in the schema, you can create a synonym. In the ADVERTISEMENTCS schema

  CREATE SYNONYM country
    FOR advertisementcs.country
  

  and then when the code of the property of ADVERTISEMENTCS wants to query the countries table, it can just

  SELECT *
    FROM country
