Using data from one-to-many relationship

Hi,
i have an one-to-many relationship among two tables similar to the structure as in the below reference:-
[One-to-many-reference|http://docs.oracle.com/cd/E23507_01/Platform.20073/RepositoryGuide/html/s1204repositoryexamplefonetomanymappi01.html]
taking this as an example, i have the city's name with me. using this data in the addr_tbl in the 'address' item-descriptor, i need to get the value of the 'name' in the usr_tbl in the 'user' item descriptor. i will have the list of 'city' with me which i have to iterate and display the corresponding 'name'.
will i be able to perform this in the jsp itself or does it have to be done in java? a sample code snippet or reference for doing this will be of much help.
thank you.

Thanks a lot, Sheik.
if i have to do the reverse, ie for the 'name' in the usr_tbl of user item-descriptor i have to fetch the 'city' values in the addr_tbl, will it suffice if i do the following?
<dsp:droplet name="/atg/dynamo/droplet/RQLQueryForEach">
<dsp:param name="queryRQL" value="name=\"sirius\""/>
<dsp:param name="repository"
value="/com/MyRepository"/>
<dsp:param name="itemDescriptor" value="user"/>
<dsp:oparam name="output">
<dsp:valueof param="element.address.city"/>
</dsp:oparam>
</dsp:droplet>

Formatted Data from 1 to many relationship tables

Hi All,
How can we get data from 1 to many relationship table in a formatted way, for example I have tables:
Search (Id, title)
Criteria (Id, searchId, radius, latitude, longitude)
Results (Id, searched, zip-code, city, state)
And I want response to look like this:
"Id":"A86E8DE3-36B0-4DBE-822E-326F84AF8FEE",
"title":"Untitled",
"criteria":{
"Id":"A86E8DE3-36B0-4DBE-822E-326F84GHFUI",
"searchId":"A86E8DE3-36B0-4DBE-822E-326F84AF8FEE",
"radius":5,
"latitude":31.2379068,
"longitude":-85.456757
"results":[
"Id":"A86E8DE3-36B0-4DBE-822E-326F8HKLLKJ",
"searchId":"A86E8DE3-36B0-4DBE-822E-326F84AF8FEE",
"zipcode":"36302",
"city":"Dothan",
"state":"Alabama"
One ugly way would be to get search data and then execute two queries against each search one for criteria and one for result. Any other way. Also sometime we to need to increase timeout of Custom API request depending on the complexity
of it. How to sort it out?
Thanks,

There are a couple of options:
Use database views. For an example, see my forum posts on this thread: https://social.msdn.microsoft.com/Forums/azure/en-US/4c056373-d5cf-4ca6-9f00-f152d2b01372/best-practice-for-syncing-related-tables-in-offline-mode?forum=azuremobile#0e23494c-1da2-4ee3-ac5a-6955d0dfed3e.
Or, if you using the .NET backend, you can use Automapper to flatten the relationships:

Complicated Question (see pdf): Use data from one table to find the same data in a second table and take other data from that table and place it in a third table. :)

I don't even know if this is posible.
I'm using iwork '09
View PDF

I hope I can clarify:
For our purposes here:
Table 1 = "Step 2 - Product Sizes"
Table 2 = "Option id Master"
Table 3 = "Export - Product Info"
Table 1:
The user would enter values for "productcode," "Horz," and "Vert"
"Size" would auto fill based on values in Horiz and Vert (I have this taken care of already).
Table 2: This is a completely static table that I want to search against. - Data from other tables in the doc does not alter or change the data in this doc.
We just want to look at table 2. Find the existing value in "table 2 : size" column that matches the "table 1 : size" column and then pull the "optionids" and "productprice" from that row.
Can the value from "Table 1 : Size" be used as a search term in "Table 2 : Size?"
Table 3: The user does not enter any values on this table.
"productcode" is pulled from table 1 - "Table 1 :: A5" = "Table 3 :: A5"
"optionids" and "productprice" are pulled from Table 2 columns "D" and "E" - however we do not know which Table 2 row it is pulling from until we enter data in Table 1.
As I'm writing this I'm realizing that
A. this is probably really confusing to you.
B. this may be impossible inside of numbers.
If you have some other method that would facilitate the same out come but be structured differently please let me know.
--- maybe to help you understand further what I am doing here is my current workflow:
I record the size of a piece of art.
Then I manually go to my "Option id Master" and find the same size.
I then copy the corresponding "optionids" and "productprice" cells. (these options control the prices displayed on my website)
I got to my "Export - Product Info" table and paste the values in the corresponding cells.
I was hoping to automate this as it takes a long time when you have hundreds of products.
Thanks for the help!

Using data from one table in another

Can anyone help me? I'm new to this.
I have a table called Mileage; Column A = Location, B = Number of miles
I want to use the data in my Business Accounts table so that when I enter a location it will automatically enter the number of miles in the cell next to it from the Mileage table.

Brilliant! Thank you.
If the Mileage table does not have a location in yet (if I've not entered it into the table yet) how can I get the result to enter an error or an oops rather than the number to the one nearest to it?
I've looked on the function descriptions but none of it is written in english
Thanks

How to insert data in a one-to-many relationship

How do you insert data into the client, my model entity beans have a one-to-many relationship.
PARENT ENTITY BEAN
PARENT-ID
PARENT-NAME
The ejbCreate(Integer parentID,String name)
CHILD ENTITY BEAN
CHILD-ID
CHILD-NAME
PARENT-ID(foreign key of PARENTID).
ejbCreate(Integer parentID,String name,String foreignparentID)
In a jsp page i collect the parent details and 3 corresponding chld details in a text box.
Can you please tell me how do i proceed from here...
ie. how to i insert data into the entity beans..
Do i pass the child as a collection, and within parents ejbCreate() method do i lookup for the childs home interface and insert one -by -one from the collection.
1. Considering the above example, can some one pls tell how the ejbCreate() mehod signatures, for the parent and child entity beans should be.
2. Pls also show some sample client code as to how to make an insertion.
3. In case you are passing a collection of child data, then in what format does one have to insert into a collection and also how does the container know how to insert the values in the child table , bcoz we are passing as a collection.
4.In case collections cannot be inserted do we need to iterate into the collection in parent's ejbCreate() method, and manually insert into the database of the childtable, thereby creating child entity beans.
Thanks for your time and support...
regards
kartik

Hi,
3. In this case of course child's ejbCreate(and postCreate) looks like
ejbCreate(Integer childID,String name,ParentLocal parent) {
setId(Id);
setName(name);
ejbPostCreate(Integer childID,String name,ParentLocal parent) {
setParent(parent);
Here you don't need IDs, but it happens only using Locals, not Remotes, if I'm not wrong. Container does it itself.
1. Of course, if you have parent.getChildren() and parent.setChildren() then you don't need any loops, but it should be done anyway in postCreate, because in ejbCreate there no parent exists yet.
Once more 3: example - I'm using JBoss 3.2.5 as EJB container. It has tomcat inside and EJB and JSP+Struts use the same jvm. It means for me that I don't need to use remote interfaces, just locals. And in this case I can implement ejb-relations. So, a have the abstract method parent.getChildren() which returns Collection of ChildLocal - s and method parent.setChildren(Collection childrenLocals) which creates/modifies children by itself.
I have not used remotes for a long time, but as I remember it was not possible to implement ejb-relations using remotes.

Gio

Summarizing data in a one-to-many relationship

Post Author: Bob Amiral
CA Forum: General
I use an order tracking system that has a one to many relationship between the main order information file and the line items file. For each order, there can be one or more items in the items file. I am having no luck trying to summarize data in such a way that shows selected information from the order file with only a summary from the item file on one line. Instead, the reports expands by adding a line for each and every entry from the item file that relates to the order.
How can I summarize data from the item file to show only one line of item data in the same line as the order data?

What types of containers need to be used for one-to-many relationships

While looking at toplink examples, I noticed that synchronized containers only are being used for one-to-many relationships even though it's not required by the documentation.
Is it required?
Also how does merge affect it? I'm gettning concurrent modification exceptions from time to time, while using iterators for containers from these relationships.
Does it mean that I have to use enumeration on vectors only and toplink merge isn't atomic? So there is no isolation when toplink merges the data from unit of work into identity maps?
There is nothing about thread-safety and threading aspects of accessing containers for CollectionMapping based relationships. Please advise.

Non synchronized containers can be used but may require some extra code to handle concurrent access. If you are accessing the objects from the shared cache (not cloned in a UnitOfWork) then you will need to isolate your iteration within a synchronized block, synchronized on the collection itself, or handle the ConncurrentModificationException if they happen rarely.
Because these are shared instances of these collections other threads may be writing to them while they are being read from.

Hi experts, how to use open sql to read data from one " maintenance view"?

i want to use this part of data within report ,so how to use open sql statement to read data from one " maintenance view"?

Hi
You can't use OPEN SQl statements to fetch data from maintenance view
You have to use only Database views
see the different types of views and the difference
The followings are different types of views:
- Database View (SE11)
Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set.
In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
- Help View ( SE54)
Help views are used to output additional information when the online help system is called.
When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.
- Projection View
Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.
A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
- Maintenance View ( SE54 )
Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
Please have a look at below link. It will help you.

Data transfer using EDI from one SAP system to other SAP system

Dear all,
I understand that i should use normal ale-idoc features to transfer data from one sap to other sap system.
but can i transfer those idocs using EDI from one SAP to other SAP system

Hello,
surely you can do so.
EDI means that you transfer data in standardized EDI-formats. To get the data at the source into that formats you normally use an EDI-Converter, which maps the IDOC-format into the EDI-format. Then you send the data in EDI-format to an EDI-converter at the target. There's the reverse mapping. You map the EDI-Format into IDOC-format and book these IDOCs into SAP.
I think this makes only sense if you cross organizational borders within the business process, e.g., if you define an exchange with many customers, but not all of them have an SAP-system.

Can I transfer data from one external drive to another using my MacAir as a platform?

I am trying to transfer about 94 Gigs of data from one external drive (Touro) to another (Seagate) using my Mac Air which only has about 14 Gigs of available space. How best can I accomplish this operation?

Niel - I know that I must be a real dunce on this. I tried opening the additional window on finder and then dragging and dropping from the Touro drive to the other open finder window for the Seagate drive. Again, it bounced back. What is NTFS? And how do I find if either or both of the drives are formatted in that manner?
Again, thanks for you help on this.
JC
PS I just got the info on the Seagate that it is Windows NTFS formatted. What do I do now? Is Paragon something I can download off the Internet? Why, since I formatted the Seagate to run on my Mac Air would there still be a problem? The packaging on the Seagate says it is compatible with Mac OS systems. jc

Can you transfer data from one numbers spreadsheet to another using conditional formatting?

I have a tracker document set up for client payments and when I indicate payment received, it flags green using conditional formatting. However I would like these to automatically transfer to another sheet - without having to cut and paste the associated data to the other sheet. Can I set up conditional formatting to do this? If not how could I get and automatic transfer?
thanks forum.

Hi Kangers,
There are a number of ways to transfer data from one table to the next. It should not be hard to set up.
Conditional formatting would not be involved it moving the data but you could set it up to flag the data in the new table.
Without knowing what your tables and data look like it is hard to propose a solution.

What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,
LaVIEWan
Solved!
Go to Solution.

Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

Best Way to port the data from one DB to another DB using Biztalk

Hi,
please suggest best way to move the data from one db to another DB using biztalk.
Currently I am doing like that, for each transaction(getting from different source tables) through receive port, and do some mapping (some custom logic for data mapping), then insert to target normalized tables(multiple tables) and back to update the status
of transaction in source table in sourceDB. It is processing one by one.
How/best we we can do it using bulk transfer and update the status. Since it has more than 10000 transaction per call.
Thanks,
Vinoth

Hi Vinoth,
For SQL Bulk inserts you can always use SQL Bulk Load
adapter.
http://www.biztalkgurus.com/biztalk_server/biztalk_blogs/b/biztalksyn/archive/2005/10/23/processing-a-large-flat-file-message-with-biztalk-and-the-sqlbulkinsert-adapter.aspx
However, even though a SQL Bulk Load adapter can efficiently insert a large amount of data into SQL you are still stuck with the issues of transmitting the
MessageBox database and the memory issues of dealing with really large messages.
I would personally suggest you to use SSIS, as you have mentioned that records have to be processed in specific time of day as opposed to when the
records are available.
Please refer to this link to get more information about SSIS: http://msdn.microsoft.com/en-us/library/ms141026.aspx
If you have any more questions related to SSIS, please ask it in
SSIS
forum and you will get specific support.
