  How can I get the counts for each parent in a single query
  
  Published by: user7955917 on August 24, 2012 07:26

  Generic function how you want the query to be.

  If the structure is known in advance, as in your example a 'books' and then a 'library' root element, it's as simple as:

  SQL> select x1.parent_id, x2.child_name, count(*)
    2  from tmp_xml t
    3     , xmltable(
    4         '/books/bookstore'
    5         passing t.object_value
    6         columns parent_id   for ordinality
    7               , child_list  xmltype path '*'
    8       ) x1
    9     , xmltable(
   10         '/*'
   11         passing x1.child_list
   12         columns child_name varchar2(30) path 'name()'
   13       ) x2
   14  group by x1.parent_id, x2.child_name
   15  order by x1.parent_id, x2.child_name
   16  ;
  
   PARENT_ID CHILD_NAME                       COUNT(*)
  ---------- ------------------------------ ----------
           1 book1                                   2

           1 book4                                   1
           2 bookn                                   1
           2 bookn_1                                 1
           2 book1                                   1
           2 book2                                   1

           3 book2                                   1
  
  10 rows selected
   
  

  If you want a generic solution that works without knowledge of the structure, you will need a recursive approach, and most importantly, you should know which nodes in distinct, I suppose that the leafs?

  Also, please help if you can provide the link of reference on the function name() years what are the other expression, that I can use after the path

  You can start reading the documentation: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAGCBGJ

  The clause PATH expects a XQuery expression however before 11.2, we can put only simple XPath expressions.

• Validation of DRM to restrict the number of nodes under a Parent

  Hi, I am creating a real-time validation, to limit the number of nodes under a parent to 1000. All new Member beyond 1000 should be erroneous outside. In order to achieve this, I created a property:

  VerParMemCount: String, node, derived

  Parameters: LessThanOrEqual (PropValue (Core.LeafChildren), 1000)

  This property was then used in the VerEssChldMemCountRT of Validation:

  Class: Property value is equivalent to the

  Level: node

  To check value: false

  Run this Validation: real-time batch and two

  When I test manually, it works. However in real time when I insert 1001 nodes or more from a parent, there is no notifications/errors. Any guidance how to do this job? DRM version: 11.1.2.1.107. Thanks in advance!

  Hello

  Please can you confirm - you have been assigned the validation to the level of hierarchy as the validation in real-time?

  Thank you

• Find the empty XML node on a table with 15 M lines

  I have a query that runs to always seek to empty xml node.

  CREATE TABLE TEST_TAB (ID number, doc XMLTYPE);

  SELECT COUNT (1)

  OF test_tab

  WHERE ((XMLEXISTS (declare default element namespace "http://oracle.com/»;)))  * / EmployeeNode / text () [not (empty (.))]'

  Are there specific oracle or operator XML text that is more effective to check null values or a specific type of text/xml index that is best suited looking for nulls in the whole of nodes?

  Thank you

  Kevin

  In the meantime, here's a test on a similar scenario.

  It seems that the structured XMLIndex gives the best response time. The obvious drawback is that she is very specific and cannot be used to solve other queries.

• Calculate the number of nodes in a version

  Hi gurus,

  Need a little help. Is it possible to discover a total number of nodes (all hierarchies combined) in a version?

  Kind regards

  Olivier M.

  Hi Olivier,.

  Run these queries on the main tables of DRM.

  All nodes in a version (inclusive orphans)

  SELECT COUNT (1)

  OF DRM_Schema.RM_NODE

  WHERE I_VERSION_ID = XXX

  NOTE- Where DRM_Schema represents the name of the repository of DRM and XXX is the version id that you can get if you do a right click on the version and check its properties.

  
  

  Total number of orphans in the Version-

  SELECT COUNT (1)

  OF DRM_Schema.RM_NODE

  WHERE I_VERSION_ID = XXX

  AND I_NODE_ID NOT IN (SELECT I_CHILD_ID

  OF DRM_Schema.RM_RELATIONSHIP

  WHERE I_VERSION_ID = XXX)

• Game max fixed the number of rows in a table

  Hi all
  
  I created a table that should contain only one line and avoid the possibility to add other lines to it, I used the following:
  

  CREATE TABLE <table_name> (
      <field_1> <field_type> unique,
      ...
      <field_2> <field_type>
      CONSTRAINT <field_1_ck> CHECK (<field_1> = <value>) 
  );

  It works, but it seems a bit heavy for me... Is there a better way to define a fixed/maximum number of rows in a table?

• Limit the number of partitions of a table can have

  Hello
  
  It has been a while I think about a simple method and the best solution to a performance problem in my application. Benefiting from the table partitioning seems a simpler approach. It involves tiny my application code changes and more, it keeps the logic of global application 100% intact. However, sometimes the number of required partitions can grow to more than 500 thousand. I know another application implementation of partitions that 50 thousand for one of his paintings. I wonder if Oracle recommends or puts a limit to a number of partitions of the table can have. How does that limit, if it exists, varies so each of my partition table contains only a small amount of data. say, no more than 2 thousand records each of size 1 KB. What are the important considerations to keep in mind while creating the huge number of partitions of a table?
  
  All entries on this would be a great help.
  
  
  Thank you

  Hello

  Place the table name with quotes. Maybe that's the problem.

  Try this code

  select table_name,
   to_number(
   extractvalue(
   xmltype(
   dbms_xmlgen.getxml('select count (*) c from "'||table_name||'"' ))
   ,'/ROWSET/ROW/C')) COUNT
   FROM USER_TABLES
   where iot_type IS NULL
  /

• Count the number of rising edges in table 1 d

  Hello

  I wanted to measure the frequency of a pulse signal using a MCC DAQ via libraries ULx in Labview. I have two methods to do this:

  1. use the analog inputs:

  Since data acquisition has only 1 ADC, I use a commune VI acquisition for all channels and create a multi-dimensional array with different channels in rows 0-15. Then divide them by using the function "Array Index".  I think this split removes the parameter 'time' to the wave, since it is now a table 1 d. But I already know that there will be 1000 samples each 100 m everything I want to do now is to count rising edges using a function and divide it by the 0.1 to obtain the frequency in Hz, but I don't know how. Can anyone help?

  2. use the input frequency meter:

  Because I can't use the DAQ assistant, I have to use the CI frequency-> counter 1ChanNSamp DBL 1 d in the ULx library. There is no reference to take aid to and I do not know if this method is good. I have no way of knowing since I do not have a signal generator. In addition, it does not work so far.

  Help, please.

  Thank you!

  Thank you.

  I note in your first post it is seems to want to get readings of speed about 10 times per second. To get a resolution of 1 Hz frequency direct count you need to get at least 2500 counts in a range of counting at the highest frequency. This means that you need to have at least a second. Measures of the time are another option.

  Some preliminary calculations:

  Period at 2500 RPM = 2500 Hz is 400,000 Americans.

  Period at 2499 RPM = 2499 Hz is 400,160 to the United States.

  You need to be able to resolve a difference of 160 ns period. To do this directly requires 6.25 MHz sampling rate.  It is 25 times faster that your DAQ card can enjoy.

  What other options are there? Consider only your Information.vi extract. He uses techniques of Fourier transformation and interpolation to find the frequency of a signal. I set up a quick test VI to check this. Using a sampling rate of 10 kech. / s and 1000 samples per read (10 reads per second), it has easily resolution of less than 0.1 Hz at both ends of the range of speed and largely independent of the amplitude.  This is the way to go.

• How to find the partitioned tables and the number of sheets in each table

  Hello friends,
  
  I have a scheme called ICS_OWNER where I partitioned and tables not partitoined.
  
  I want to list all the tables that are partitioned.
  
  and also
  
  I want to know what partitions exists in every partitioned table.
  
  with respective schema specified
  
  Thank you/Kumar

  When you have questions like this, you don't ask here.
  but you take your (or should I say 'your') keyboard
  and type
  Select *.
  dict
  where table_name like ' % PART %.
  /

  All the dictionary views are listed in the DICT.
