Scenario of two parents SelectoneChoice and child selectOneChoice

Hello

I use jdev 11.1.1.5

I use selectOneChoice cascading. Everything is working fine.but I had another requirement. I have search Vo, that have all of the transient attributes.

few attribute this choice VO have LOV. For example

I have childLov1 and parent1 lov. ChildLov1 have views on the criteria that is passed by the attribute of parentLov1.Now I have an another parentLov2 which is almost identical to parentLov1.

My use case is updated on the basis of parentLov1 or parentLov2 childLov1. Setting a day will come from parentLov1 or, sometimes, parentLov2

How to get there?

All three lov of a VO research? Please suggest?

I solved this problem using the variable layout application session

How to upgrade the parent table and child by updating the parent table
I have a parent EMPLOYEE table that includes columns (sysid, serviceno, employeename...) sysid is the primary key, serviceno is the Unique key and I have DEPENDENT child table includes columns (sysid, employee_sysid, name, date of birth...) there still SYSID is a primary key for the table of dependants, employee_sysid is a foreign key in the EMPLOYEE table.

Now I want to change SYSID (with the help of the sequence) in the EMPLOYEE table that they want an update in the table of people dependent

Note: I have 10000 records in the EMPLOYEE table as I have 5 more children tables that need to update new SYSID.

Please help me
first disable FOREIGN KEY constraints.
You can update Parent and child record with the help of the trigger.
Here I give you an examlpe... It can help u.

create a parent (id number primary key, name varchar2 (100)) table

parent columns and child
Hello world

I have a table "test_table" like below where there is a child column and the parent column. I need to write a query to find out the values of column of child who does not exist in the parent column. I wrote something like that works but is it the right way, or is there a better way?

Thank you

parent of the child
100 200
200 300
300
400

Query:

Select child test_table
where mother <>

Thank you.

PK
Hello

The answer to your question is this query:

SELECT t.child FROM test_table t
WHERE NOT EXISTS (SELECT 1 FROM t1 test_table WHERE t1.child = t.parent);

This get you all the lines where there is no parent with the same value.

However: Why would you have a table like this one with the parent-child relationship within the same table?

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

Responsive HTML5 with mergedprojects, creates a hyperlink to a file in the project html parent to a child html file and it does not work! The child has with the parent TOC, but need to tie. Help, please!

Hi group!
I have a brilliant parent project that serves as a springboard for other projects. Users click a component of software they want and are redirected to a page with a list of all the documentation available for this component. Click on the name of a document and access - a lot of PDF files. BUT I also wish they were able to tie the online help for the component. After having read up on the link through / between projects, I knew that I needed to create a parent project (for the page intro and links brilliant) and projects for children (for software components).
THEN
I created a parent sensitive HTML5 project and the projects of two children. I compiled the parent to create mergedprojects files, and then open the projects children and collected to the appropriate mergedprojects folder. I then created a hyperlink to the file list html documentation in the project parent towards the child file software component html (output folder and start page [which is the same as the default theme]) and the link does not work! The child and its table of contents appears in the parent TOC so topics are here, but I can't link to them. If necessary, I can send screenshots.
Where I am dorking this place?
Thanks in advance for your time and help!
Scottie 'needs help' gear

What is your relationship like? And how did you create the link?

A typical reactive merged help is structured as follows:

index.htm (Master home page)

mergedProjects

childName

index.htm (starting page for child)

A child from the index.htm page link would look like this:... /... index.htm

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" 
           xmlns:xdb="http://xmlns.oracle.com/xdb"
           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:sequence>
            <xs:element name="child" type="Child_T" minOccurs="1" maxOccurs="unbounded" xdb:SQLName="CHILD"
                      xdb:SQLInline="false" xdb:defaultTable="CHILD" "/>
        </xs:sequence>
        <xs:attribute name="ID" xdb:SQLName="ID" use="required" />
    </xs:complexType>
    
    <xs:complexType name="Child_T" xdb:SQLType="CHILD_T">
       <xs:sequence>
         <xs:element name="name" type="xs:string" xdb:SQLName="NAME"/>
       </xs:sequence>
     </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
</parent>

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?

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
Vishal
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?

BULL, INSERTION IN THE PARENT TABLE AND THE CHILD TABLE
Hi all

We use bulk insert to improve performance. How to use this concept when I insert the records parent in table parent and child?

example... I have a procedure that accepts the array of student objects

each student object is defined as *(student name, student age, course_object_array) *.

the 3rd element course_object_array is defined as *(coursename,course fee,facultyname) *.

a student can be associated with several courses

Now, I have to insert the data into two tables namely students (studentname, studentage and student_number)
courses (course_id, coursename, fees, facultlyname, student_number)

I use sequences to fill the columns student_number and course_id.

If I use bulk insert, and insert all the records in the parent table how do I the association for each record of a child. How will I know what child folder must be associated with which of the parents?

Hi thanks for the reply Solomon.

I actually know about the bulk collect and for all...

Have you read that FOR ALL with in fact BULK COLLECT? It will allow you to bulk insert via for ALL with VOTING student_numbers attributed to each student placed in a collection. Then, you will use this collection collection of course list to fill the RACE table.

Problems with the Parent and child Pages...

I created a parent page with several pages of the child, but when I transferred to my host FTP pages do not come to the top in the hierarchy in the URL bar. I want it to be "www.website.com/parent/child.html" but they come as 'www.website.com/child.html '.
How can I change this? I thought that by creating a page parent to the child which would automatically when loading pages. Help, please!
Thank you!!!

Muse currently publishes all the pages in the root directory of the Web server. It does not create a folder structure based on the structure of the site defined in Plan view. The structure of the site defined in the Plan view is used by the Widget Menu to generate Menus correspondents and submenu entries.

Hope that specified in the query.

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.

How to access the methods of the / in the parent and child responsible sovereign wealth funds?

Hello world
Imagine the following configuration. The main SWF load a child swf file.
In AS2, I would use just _parent or _root to call the desired function. How can be done in AS3?
Is it still possible? Can I call a function on the main swf that loaded? What happened the other way around, this time of principal to the loaded swf format?
Thanks for the support!
See you soon
:::-)

In AS3, you can call the _parent (AS2) using MovieClip (parent) (AS3) and similar to the _root. If you load a child swf, you must understand that the child normally lives in the charger you loaded with, so to return to the loaded swf file you have to go (parent.parent) MovieClip.

So much to talk to the child going to swf, go through the following discussion... http://forums.Adobe.com/thread/720211?TSTART=0

The professional events and child master relationship
Hi all

Consider there are two entities in a master-child relationship, is there a way to trigger the event of business such that the payload contains several details of a row for each master.
I guess that declaratively, we must publish log sales on master and child entities separately.
Is there another possible way?

Thank you
Lalit.
Lalit,

Your use case makes sense to me. My personal opinion is that the docs for business events in British Colombia ADF are a little light; However, there is a paragraph that gives a hint of a glimmer of a grain of hope that can run your scenario:

To support scenarios of composition (for example, an order to buy with invoice lines), a child
entity can raise events defined on the entity relationship and events defined on the child
entity can include attributes of the parent entity. When a child entity raises an event
on a parent entity, only one event is triggered for a top-level entity given by
transaction, no matter how many times the child entity triggers the it.

You have a relationship defined between your master/child entities composition?

I had not the time personally to play with log sales again, unfortunately :(

Contextual menu tree different for parent elements and children

Hi people, I'm trying to write a vi with a tree control... I was able to create a context menu for the item parent by right clicking on the tree-> Advanced-> Run - Time control-> context Menu-> Edit... However, I would like to create two menus, one adapted to the parent element and the other specific to the child elements... any help? Thank you

I think you need to dynamically create your run menu according to the selected item in the tree control. You can do this by using the menu running events and the functions in the menu in LabVIEW.

There is a palette for this:

Cannot use casting "to more specific class ' function to the parent class of child class

Hello

I am using OOP for my request for data acquisition. I have different e/s analog and digital materials. I create a superclass named DAQ.lvclass. This class has four childs: analog in out analog, digital, and Digital Out. I am trying to invoke screws of the child of the parent class's class. For that I am throwing the class parent her child to aid "to a more specific class' function. But I get the below error.

Error 1448 occurred at the more class specific in DAQ.lvclassMain.vi AQ

Possible reasons:

LabVIEW: Bad type cast. LabVIEW does not deal with the run-time value of this class of LabVIEW as an instance of the given class of LabVIEW.

How can I handle these cases where I have to call child VI of the parent member?

I have attached two screws 1 snapshot. Main DAQ: it's the class main VI parent who manages all functions. 2. read the analog inputs: this VI trying to set the parent class for its class of the child and child vi reads value of data acquisition task. I get the second error off VI.

Kindly help.

Honestly, I have NO idea on what you want to do.

Inheritance of classes in EACH OOD (object-oriented design) requires to define common ground as the parent class. Children can add things like properties and methods.

If you set children who have no points in common, you have made a mistake.

If all children have too many different specific methods, your OOD is absent.

Example:

Parent defines the method A.

1 child adds the B method.

Child 2 adds method C.

But method B will not be usable on 2 children while method C will not work with 1 child.

It is an approach that you want to prevent. In any programming language oriented OBJECT. This adds unnecessary complexity leading to difficult to maintain the code, and it is prone to errors.

However, if you're going to do, "to more specific class ' is the correct type cast. But your screenshots and error messages, it is obvious that refine you a particular child's casting only. You must extend the code to check the real child, specifically expressed and call the method. That being said, your code increases the complexity you want to add a bunch of case of structures which essentially nihilates all THE BENEFITS of the use of OOP.

I'm sorry to say that.
