Why Developer SQL displays arrows (relations) between parent and child tables in my entity relationship diagram?

• Cursors for parent and child, bind variable and library cache

  I was going through the documentation to understand the difference between the parent and the child cursors. Surprisingly, there's not too much help for this. I was able to collect the following information about this
  
  For each statement SQL cache library contains a cursor "parent" for the text of the SQL statement. The parent cursor is composed of a "handle" that can be searched by the hash value via the library cache hash table and an «object' which contains pointers to each of its «child» cursors Each cursor of the child is also composed of a handle and an object. The child object is composed of two segments numbered from 0 to 6. Lot 0 contains all the credentials for a particular version of the SQL statement and lot 6 contains the execution plan. This distinction between parent and child cursors is maintained even when there is only one version of each SQL statement.
  
  Lets say that 2 LMD were fired with the same set of variables bind (names of variables were same but differed from the value.) The only difference between the 2 LMD was the value of the variable binding) and under the same conditions of load.
  
  These DML 2 would be a sliders 2 children of one parent only cursors.
  
  Please tell me detailed documentation on the subject, so my question is too elementary
  
  Kind regards

  I'm not sure how useful jumping in stuff like bunch 0 and 6 bunch is in terms of understanding what is a parent and what is a child cursor.
  This quote seems to come from Steve Adams - http://www.ixora.com.au/q+a/0104/19005414.htm
  It's a good idea to cite your references.

  I'll give it a go.

  A cursor is a lot of information stored in memory on a SQL statement.

  The basic information for a parent cursor is the text of the SQL statement - exact matches of the statement can only share the parent cursor.

  The cursor of the child is really on the implementation plan specific for a statement and the different settings and parameters that caused this plan to be generated.

  There are a whole bunch of reasons why the executions of the same SQL statement may or may not reuse the existing child cursors.

  In your example 2 statements that differ by the variable binding are likely to lead to different children, although there are factors that can lead to lie different values, do not share the same children among whom for example, the length of the dregs, Adaptive setting cursor_sharing = similar and histograms, or new features like cursor sharing (on subsequent runs of renowned sql running suboptimal initially).

  It might be useful to see V$ SQL_SHARED_CURSOR. This shows the disparities that cause children to not be shared. There are more than 60 columns in this view which gives an indication of the number of factors that can influence.

  Away from the main documentation, perhaps some of the writings of the optimizer Development Group could help?

• Parsing sql - cursor parent and child

  Hi all
  
  What is the parent and child when parsing sql cursor?
  
  Thank you
  
  John

  Well, as Anand mentioned you could yourself. Here's a demo of the workaround based. Based on the change of environment, the sliders would be created and will not be shared that I made using the change of parameter of optimizer_mode. This is done in 11201 with the setting optimizer_features_enable on 10201.

  You can see an inconsistency in the optimizer_mode resulting in another creation of child cursor. You can try to use the parameter cursor_sharing similar value and bind variables that would also cause child several sliders to create. For the view V$ sql_shared_cursor, check the docs.

  Hello

  Thanks for posting your question in the Microsoft Community.

  Sinc you want to determine the parent and the child rights usings script as an exe of java or xml, the question you posted would be best suited in the MSDN Forums. I would recommend posting your query in the MSDN Forums for further assistance:

• composite unique constraint on the values of parent and child?

  Is it possible to have a composite unique constraint that contains the values of the child elements? The example below has the "child" elements are offline, but it's preferred, but optional, I know that you can have a unique constraint in the set of tables without using a reference table that contains the constraint and the two columns. How xdb manages this requirement?
  
  permit:

  <parent ID="1">
     <child><name>test1</name></child>
     <child><name>test2</name></child>
  </parent>
  <parent ID="2">
     <child><name>test1</name></child>
     <child><name>test2</name></child>
  </parent>

  not allowed:

  <parent ID="1">
     <child><name>test1</name></child>
     <child><name>test1</name></child>
  </parent>

  <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"

             xdb:storeVarrayAsTable="true"
             elementFormDefault="qualified">
      
      <xs:element name="parent" type="Parent_T"
          xdb:columnProps="CONSTRAINT parent_pkey PRIMARY KEY (XMLDATA.ID)"
          xdb:defaultTable="PARENT"/>
  
      <xs:complexType name="Parent_T" xdb:SQLType="PARENT_T" xdb:maintainDOM="false">

       </xs:complexType>     
  </xs:schema>

  xdb:columnProps = "CONSTRAINT parent_pkey PRIMARY KEY (XMLDATA.ID), * UNIQUE (XMLDATA.» "Child.Name) *" triggers the non-existent attribute
  
  
  A possible solution would be to copy the value of the primary key parent of the child element, then I could create a composite unique constraint using only the values of the child. However, I have this same requirement elsewhere in my lowest nested schema, and it can become messy / bad design with cascading of all primary keys on the schema. For example, I have a recursive element in which two attributes must be unique only within the parent company:

  <parent id="1">
     <child a="1" b="1">
        <child a="1" b="2">
           <child a="1" b="1" /> *not allowed
        </child>
     </child>
     <child a="1" b="2" /> *not allowed

  Possible solution:

  <child a="1" b="2" parent_id="1" />
  <xs:complexType name="Child_T>
     <xs:sequence>
        <xs:element name="child" xsd:SQLInline="false" xsd:columnProps="UNIQUE(XMLDATA.a,XMLDATA.b,XMLDATA.parent_id)" minOccurs="0" maxOccurs="unbounded" type="Child_T">
     </xs:sequence>
     </xs:element
  </xs:complexType>

  Is there a better design?

• link between po and mtl tables

  Hello
  
  is there a link between po_headers_all and the inventory of the super user as mtl_system_items tables
  
  I need this info to get the last provider (according to the date of approval) for each element
  
  kindly Guide
  
  thanking in advance

  Hello

  There is no direct link between po_headers_all and mtl_system_items_b. You need to connect through po_lines_all:

  po_headers_all.po_header_id = po_lines_all.po_header_id
  po_lines_all.item_id = inventory_item_id mtl_system_items_b.

  It will be useful.

• difference between materailized and a table

  Hey hiii
  
  I want to know what is a difference between a materialized view and that is to say a table suppose I create a table and another table B on the table, I created a trigger that will download all changes made to A, it IE insert, update or delete while it will perform all actions that a materialized view can perform on one or is there a difference between them
  
  
  
  Thks

  In this case, MView will be much more robust and reliable, because it is designed for that you use coding the trigger. You will manage all possible exceptions and lock the trigger claim everything is Oracle build-in MView. And also, MView can be much more powerful.

• Difference between Parent and Parent Curr Adjs

  Hi gurus,
  
  Please explain the difference between the Parent Adjs and Parent Curr Adjs.
  
  Thanks in advance

  Consider two members in the dimension entity 'A' and 'B' now these two members have a child as 'C '. Where 'C' is the shared member. Now if you switch a log to of the 'C' then this log entry has an effect on both parents 'A' and 'B '. While if you place an entry in the of the 'C' then you can also select the parent you want to get affected by the same.

  Hope this is useful

• Relative time with the Parent and child Comps

  Hi, is it possible to see the time a child-comp has in her own scenario, and in his own timeline window see what time there in a certain-comps-chronology kinship?

  I tried several views, but could not display 2 different comps and / or move the time slider to a model he moves in the other computer too...

  Kind regards

  Frank

  Well, that said Rick is the first to check, but by default, this option is enabled, so I wonder... Your compositions are in fact really nested or y at - it something to do that we do not know? As well use the parameters of the model and adjust the com time beginning when necessary. Desp you can always use simple expressions for anotehr comp time and attach it to the effect numbers...

• Displays text different between reader and acrobat

  Hey

  Had a little problem just installed adobe acrobat X on a computer and when to open documents text looks like "fuzzy" which is the best way to describe what it looks like.  the letters have no sharp edges more pixelated.  If I open the same document in adobe reader 9, it seems.  I have run all the updates for adobe acrobat X and even performed a repair installation.  still no change.  Here is a screenshot of the problem text above was the software adobe reader 9, the text down was acrobat adobe x

  the two zoom in to 150%

  Thank you

  Did you compare / order the settings in the preferences (Edit/Preferences /Page Display)?  "" There are a couple of settings under Page display that could be the culprit - it is useful to check the "rendering" section that the smooth text option has defined appropriate monitor and I personally smooth linework, smooth images and improve fine lines checked. Hope that helps.

• You want to know why the icons displayed for only some bookmarks and how to replace the rectangle with an icon dotted valid in these cases.

  As explained in the question, some of the icons for sites appear only as a dotted rectangle. There are several favorites that have been imported from a html file and some of them have no icon showing on the list of bookmark or toolbar for Firefox, but they did it on the original browser where they wre imported. As a general rule, the icons 'fills' when each of the imported sites are visited some do not no matter how many times visited.

  I checked to make sure that the fonts and colors are chosen by the site server, so this isn't the problem.

  Although it is a function a little cosmetic (navigation works fine, just no icons), the icons site much faster recognition visually, making the browser it much faster and easier on the eye.

  Any help to fix this would be greatly appreciated for a user of Firefox "second-time-around."

  Firefox normally restore the favicon if use you this bookmark.

  Dear experts,

  I need to create a form wizard with train and train the child parent. The request is to make parents to train the train left and a child in the middle. The train of the child in the course of parent is hidden.

  Do you have any suggestions?

• Question packets parent and child

  Hello

  Greetings!

  I have a Parent package and a child package that have around 20 packs inside.

  When I run the parent package and a child, the parent package runs in a few seconds, but the 20 jobs in child packages takes 1 hour of time to execute.

  In operator, it is the final parent package watch while the child packages takes time to complete. Have first child packages must complete and Parent packets after that.

  No idea why this happening.we also by controlling refreshing but his does not work.

  Thank you

  Lony

  If you call asynchronously a child/scenario package then it will return control to its parent immediately, what is the nature of asynchronous operations and you to have several processes running in parallel. If you don't want the Parent to complete its execution until all her children are processing you have 2 options:

  (1) not to call asynchronously the child, if you do not have many children parallel execution is the usual approach

  (2) However, if you have several children, parallel execution, make use of the odiwaitforchildsesion tool. You use once at the beginning of the sequence run in parallel and once at the end and this will ensure that your parent package will wait for all asynchronous operations to complete before continue. This link gives a good overview of how to implement asynchronous - parallel execution - ODIExperts.com

• Performance problem with SQL for recovering data in FACT and Dimension Table

  Hello

  We have a query that performs very slow when extracting data in FACT and the DIMENSION Table.

  SQL and Plan are in the attachment.

  Please suggest how this can be improved.

  The version of DB is 11.2.0.4

  Kind regards

  VN

  Slow is a very relative term, for about 1 hour is slow for some 1s is slow. So please always quantify your settings.

  The first thing caught my eye is done 4 times ia_oasis_tot_prov_cur_d access. Try to isolate which and change it like this and see if it returns the same result.

  select case when a.clm_capitn_ia_bil_prov_edw_sk = b.prov_edw_sk then b.prov_id end ben_billing_prov
       , case when a.clm_capitn_attnd_prov_edw_sk  = b.prov_edw_sk then b.prov_id end ben_attending_prov
       , case when a.clm_capitn_ia_pcp_edw_sk      = b.prov_edw_sk then b.prov_id end ben_pcp_number
       , case when a.clm_capitn_ia_ipa_prov_edw_sk = b.prov_edw_sk then b.prov_id end ben_ipa_number
    from edw.clm_capitn_f partition (jan2015) a
    left join
         edw.ia_oasis_tot_prov_cur_d b
      on (
             a.clm_capitn_ia_bil_prov_edw_sk = b.prov_edw_sk
          or a.clm_capitn_attnd_prov_edw_sk  = b.prov_edw_sk
          or a.clm_capitn_ia_pcp_edw_sk      = b.prov_edw_sk
          or a.clm_capitn_ia_ipa_prov_edw_sk = b.prov_edw_sk
         )
  

  If it works this means allows you to reduce certain I/O.
