Question on multiple table view controllers

Hey there,
I don't need to know the exact code of how to do this, I am just wondering for now if this is the right way to do this.
What I want is my Root View to have 3 prototype cells(including disclosure indicators), including a subtitle, and 1 button at the bottom of the prototype cells.
When tapping a cell, (there are 3 different table view controllers that can open, depending on the cell chosen), it pushes to a Table View Controller that allows the user to tap a row they want, a check mark shows the row they tapped, then when they tap the back button to go back to the Root View, I want their choice from the Table VC they were just at, to show up in the subtitle field under the prototype cell they chose. Same goes for the other 2 prototype cells.
Once the user has chosen all 3 and can see their choices in the prototype cell's subtitle, they can tap the submit button, and it will read from a database, querying all the selections from the 3 subtitles in the root view, and take them to a new Table VC that displays the results, with disclosure indicators for each selection from the database. They can go back to the Root VC, or they can choose a row from the database results and go into the Detail VC for that selection.
I hope this makes sense, so I ask this:
1. Is this the best way to pass data back to the Root VC, as in using the subtitle of the prototype cell's. I liked it because the subtitle is smaller than the cell so it shows what you chose from the Table VC you were at and checked a certain value from.
2. If this is the way to do it, how do I pass the values from the Table VC that has a checkmark that you chose, back to the Root VC's subtitle for that cell you initially chose.
Side note: The button on my Root VC takes up the whole width of the screen and i can't seem to change it, is there a way to customize the size with my mouse or do I need to write custom code?
I am not at home so I can attach pics later as I have a 'not working model' that shows what I am doing and might be easier to udnerstand.
Any help is definitely appreciated as I just need to know if I am on the right track.
Thanks!!

Insert into multiple table view

I have a view with multiple table query and and INSTEAD OF trigger on the view that inserts into multiple tables. When I attempt to do a commit out of a ADF Creation Form, I get the following error: ORA-01779: cannot modify a column which maps to a non key-preserved table ORA-06512: at line 1.
Has anyone had success inserting into multiple tables via a view that has more than one table?
Thanks,
Lisa

Lisa,
Sounds like your instead-of trigger may not be being called and you are trying to insert directly into the view.
I did write a [url http://stegemanoracle.wordpress.com/2006/03/15/using-updatable-views-with-adf/]blog entry about using a view with instead-of triggers last year.

Question about multiple tables and formulas in numbers

I was wondering about having a formula that effects one table based on data in the other table. I have a spreedsheet that i created for work. In column A is a list of addresses. In column B-ZZ is a list of "billing codes" the get applied to the service work done for that address.Its kind of difficult to look at this large spreadsheet on my iphone and edit it on the go. Is there a way to, Have another column, possibly on sheet 2 or something, where i type in these "billing codes" and they would fill an x or some other character in cell that corrisponds with that billing code on that address line? So to be as plain as possible, I want to enter data in one cell (another sheet if possible) and have it "mark" another cell in response to the specific data on that "entry cell." Im thinking this way because instead of scrolling back and fourth on the sheet on my iphone, to "mark" the boxes, i could just navigate to sheet 2 enter the data, or "billing codes" and they would "X" the cell that would match up with the code column and address row. each address row would have a seperate "entry field" in sheet 2, to make the formula easier. thanks for any help

Tom,
That's a lot of columns for jsut a table of marks that reflect an input. Sure, you could have each cell in that giant table check to see if some corresponding cell contains certain text, but that document is going to be slower than you might be able to tolerate.

Question about multiple table JOIN syntax

Good morning,
I'm trying to join three tables and getting an error. Here is the query:
with
p (messageid, parentmessageid, subject) as
    select 2001, null, 'xyz'    from dual union all
    select 2002, 2001, 'ngh'    from dual union all
    select 2003, 2001, 'nghj'   from dual union all
    select 2004, 2001, 'pppp'   from dual union all
    select 2005, null, 'hhhhh' from dual union all
    select 2006, 2005, 'hhhhj' from dual
m (thread, messageid) as
    select 1004, 2001           from dual union all
    select 1005, 2006           from dual
select p2.messageid, p2.parentmessageid, p2.subject
from (p p2 left outer join m m2
                          on (p2.parentmessageid = m2.messageid))
       join m m3
         on m3.messageid = p2.messageid
;                which gives an "ORA-00918: column ambiguously defined.
I can't figure out why it gives that error. I fail to see the ambiguity.
Thank you for helping,
John.
P.S: In case someone wants to get a good laugh, here is a "solution" that does not have any ambiguity:
with
parentchild (messageid, parentmessageid, subject) as
    select 2001, null, 'xyz'    from dual union all
    select 2002, 2001, 'ngh'    from dual union all
    select 2003, 2001, 'nghj'   from dual union all
    select 2004, 2001, 'pppp'   from dual union all
    select 2005, null, 'hhhhh' from dual union all
    select 2006, 2005, 'hhhhj' from dual
messagethread (thread, messageid) as
    select 1004, 2001           from dual union all
    select 1005, 2006           from dual
j1 as
   select p.messageid, p.parentmessageid, p.subject, m.thread
     from parentchild                     p
          left outer join messagethread   m
                       on p.parentmessageid = m.messageid
j2 as
   select j1.messageid, j1.parentmessageid, j1.subject, j1.thread, m.thread t2
     from j1 left join messagethread m
       on j1.messageid = m.messageid
select j2.messageid, j2.parentmessageid, j2.subject, nvl(j2.thread, t2)
from j2
order by messageid

John.I tried NO_QUERY_TRANSFORMATION and MATERIALIZE but the error still was there. So it might not be a problem of rewriting the query.

Ability to query on all columns from a view with multiple tables

I have view with 4 tables. view has about 50 columns.
hypothetically, I want to build a form to give the user an ability to query on any of those 50 columns. user can search on one or more fields.
what is the best way to write the query to retrieve the results without performance impact.
please let me know if the question is not clear.

If you want to permit them to query any of 10 fields with no restrictions, you could create 10 separate single-column indexes. The optimizer would have to try to pick the best of these indexes if you specified multiple search criteria. But since you have a view which presumably means that you've got multiple other indexes involved for the underlying join conditions, you'd probably want/need to combine the column lists of the indexes you're adding for searches with the indexes you've created for joins, which requires looking at the text of the view and figuring out the best way to optimize the 10 single-column searches. Of course, it is possible that the optimizer could chose to do something like a b-tree to bitmap conversion on multiple indexes which could allow it to use multiple independent indexes for your queries, but that's generally not ideal performance-wise.
All this is a fancy way of saying that there probably isn't a cut and dried answer to your question. You need to figure out the queries you're trying to optimize (say, the 10 single-condition queries) and you need to figure out what set of indexes on the various underlying tables provides the best performance weighing those benefits against the cost on other side of maintenance during DML. Which is going to depend on the text of the view, the underlying tables, the existing indexes, etc.

Want to update data in a view based on multiple tables

Hi
I am facing a problem i want to update data in tables using a view. As that view is based on multiple tables so i am unable to update data. i came to know we can update table from view only if view is based on single table. so if anyone knows any alternative please let me know.
Thanx
Devinder

Devinder,
The table can be updated through a view based on multiple tables, if and only if the table is a "key preserved" table. Rather than explaining myself, i avoided the burden of typing by finding the material in Oracle Docs and pasting it for you :-)
If you want a join view to be updatable, all of the following conditions must be
true:
1. The DML statement must affect only one table underlying the join.
2. For an INSERT statement, the view must not be created WITH CHECK
OPTION, and all columns into which values are inserted must come from a
key-preserved table. A key-preserved table in one for which every primary
key or unique key value in the base table is also unique in the join view.
3. For an UPDATE statement, all columns updated must be extracted from a
key-preserved table. If the view was created WITH CHECK OPTION, join
columns and columns taken from tables that are referenced more than once
in the view must be shielded from UPDATE.
4. For a DELETE statement, the join can have one and only one key-preserved
table. That table can appear more than once in the join, unless the view was
created WITH CHECK OPTION.

[ADF Help] How to create a view for multiple tables

Hi,
I am using Jdeveloper 11G and ADF framework, and trying to create a view to update multiple tables.
ex:
Table A has these fields: ID, Name
Table B has these fields: ID, Address
A.ID and B.ID are primary keys.
B.ID has FK relationship with A.ID
(basically, these tables have one-to-one relation)
I want to create a view object, which contains these fields: B.ID (or A.ID), A.Name, B.Address.
So I can execute C,R,U,D for both tables.
I create these tables in DB, and create entity objects for these tables.
So there are 2 entity objects and 1 association.
Then I create a view object based on B and add fields of A into the view:
If the association is not a "Composition Association",
when I run the model ("Oracle Business Component Browser") and try to insert new data, fields of A can't edit.
If the association is a "Composition Association", and click the insert button, I will get
"oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity"
If I create a view object based on A and add filed of B into the view:
When I run the model and try to insert new data, fields of B can't edit, no matter the association is or is not a composition association.
So... how can I create a view for multiple tables correctly?
Thanks for any advices!
Here are some pictures about my problem, if there is any unclear point, please let me know.

Edited by: user8093176 on Oct 25, 2009 12:29 AM

Hi Branislav,
Thanks, but the result is same ....
In the step 2 of creating view object, I can select entity objects to be added in to the view.
If I select A first, and then select B (the "Source Usage" of B is A), then finishing the wizards.
When I try to create a new record in the view, I can't edit any properties of B (those files are disabled).
If I select B first, and then select A in crating view object, the result is similar ...
Thanks for any further suggestion.

How do I reference multiple tables in SSAS Data Source View Named Calculation functionality?

Hi SSASers -
On the Data Source View node of SSAS Visual Studio Interface, I want to create a named calculation that references multiple tables. Something like: CASE WHEN tableA.Column1 = 'Y' Then tableB.Column1 ELSE tableB.Column2 End, but the compiler throws an error
here "Deferred prepare could not be completed".
What is the syntax for referencing multiple tables on this node or how else can multiple tables be used to create a calculated value in SSAS? I'm new to SSAS and so far have been building big views and building calculations this way. Another option is the
Calculation tab off the cube node but this calculation will need to be based off of dimensions AND measures so please provide a syntax example here also.
Thanks in advance!
Carl

Thanks Jiri! The named query functionality off the Data Source View node is exactly what I was looking for - it's just a view on the SSAS side of things instead of the relational dbase.
Sorry for the delayed answer verification - got pulled into something else last week. Carl

Create opaque view in OBIEE with multiple tables

Hi,
I need some help with the opaque view since i have never created it in past. I want to create an opaque view which fetches data from multiple tables. Is it possible to do that ? Or is there any other alternate option available in OBIEE ? I read the following blog and other similar blogs on opaque views but could not find option to use it for query with multiple tables:
Oracle Business Intelligence: Creating Opaque View in Physical Layer in OBIEE 10g
Also can you please advice how to join two tables from different databases in OBIEE ?
Kindly advice.
Regards,
Andy

Hi Andy,
As per my knowledge you can create Opaque View on one table at a time.Joining two tables from different databases yes we can create a report from multiple data sources.Check this

Creat View from Multiple tables , Multiple Select

Hello Everyone ,
I have a question and am not sure if this the correct forum to post it .
I have two table studentTable and CourseTable which is each student take more than one course . 1:M
for example Student1 take 2 courses (C1 , C2).
Student2 take 3 courses (C1,C2, C3).
I need to create a table/View that contain student information plus all the courses and the score for each course in one row.
for example
Row1= Student1_Id ,C1_code ,C1_name ,C1_Score ,C2_code,C2_name ,C2_Score
Row2=
Student2_Id,C1_code, C1_name,C1_Score,C2_code ,C2_name ,C2_Score , C3_code,C3_name,C3_Score
and since Student 1 just took two courses , I should enter NULL in 'Course 3 fields'
My Struggle is in the insert statement
I tried the following but it show an error
Insert Into Newtable
( St_ID, C1_code,c1_name, C1_Score ,C2_code ,C2_name,C2_score,C3_code ,C3_name,C3_score)
Select
(Select St_ID from StudentTable)
(Select C_code,c_name,c_Score
from Coursetable,SudentTable
where course.Stid =Studet.stid)
(Select C_code,c_name,c_Score
from course ,student
where course.Stid =Studet.stid ),
(Select C_code,c_name,c_Score
from course ,student
where course.Stid =Studet.stid );
I'm fully aware that the New table will break the rules of normalization ,but I need it in this way for specifc purpose.
I tried also the PIVOT BY functionality but no luck with it .
FYI , I'm not expert in using SQL Syntax , I just know the basic.
I will be great full for any helpfull suggestions to try ,
thank you very much.

First Table is Member table which Represent
Students Information
.The fields in this table are
member_sk (PrimaryKey), full_or_part_time, gender, age_at_entry, age_band_at_entry, disability, ethnicity,
widening_participation_level, nationality
Second Table is Modules table which include
the Courses' scores that Student took .
The fields in this table are
Module_result_k(Primary Key), member_sk(Foreign key to connect to Member table), member_stage_sk
,module_k(Foreign key to connect to Module table), module_confirmed_grade_src, credit_or_result
Third Table is
AllModuleInfo which is include
general information for each course .The fields in this table are
Module_k (Primary key), module_name ,module_code, Module_credit, Module stage.
The New table
that I will create has the following fields
member_sk (PrimaryKey), full_or_part_time, gender, age_at_entry, age_band_at_entry, disability, ethnicity,
widening_participation_level, nationality
" This will be retrieved from Member table"
Also will include
Module 1_name ,module1_code, Module1_credit, Module1_ stage, member1_stage_sk
, module1_confirmed_grade_src, credit1_or_result
Module 2_name ,module2_code, Module2_credit, Module2_ stage, member2_stage_sk
, module2_confirmed_grade_src, credit2_or_result
I will repeat this fields 14 times which is equal to Maximum courses number
that any of the students took.
//// I hope now my questions become more clear

Table View with Multiple Context Nodes

I want to create a table-view consisting of an object composition, e.g. multiple business objects. The chtml:configCellerator -tag supports just one context node which corresponds to just one business object.
How do you create a table composed by different objects, i.e. BTAdminH and BTAdminI ?
Edited by: romanglass on May 18, 2010 4:07 PM

Hi,
I would suggest to create a new component and not to disturb the standard ones. Because the super class of the header context node (BTAdminH in your case) must be inherited from CL_BSP_WD_CONTEXT_NODE_DTV - Deep table view.
The dependent nodes must be passed to return parameter rt_result of method GET_SUB_CNODE_DEFINITIONS.
This cant be done via wizard. I just tried to replicate your scenario. Below are the steps,
1. create a view with context node BTADMINH as tableview. Then change the super class of the context node to CL_BSP_WD_CONTEXT_NODE_DTV.
2. Add another context node BTADMINI and mark it as dependent to BTADMINH.
3. Now change the super class of context node BTADMINI to CL_BSP_WD_CONTEXT_NODE_TV (Table View).
4. Redefine method GET_SUB_CNODE_DEFINITIONS in context node BTADMINH.
In the view layout you should use cellerator and pass an iterator with interface IF_THTMLB_CELLERATOR_ITERATOR. The interface has a method RENDER_DEPENDANT_OBJECTS which returns the table of dependant objects.

Arun

Passing Multiple table row from one view to another view

Hi,
How to Passing Multiple table row from one view to another view in Web Dynpro Abap. (Table UI Element)
thanx....

Hi Ganesh,
Kindly do search before posting.. this discussed many times..
First create your context in component controller, and do context mapping in two views so that you can get values from
one veiw to any views.
and for multiple selection, for table we have property selection mode.. set as multi and remember context node selection
selection cardinality shoud be 0-n.
so, select n no of rows and based on some action call sec view and display data.( i think you know navigation between veiw ).
Pelase check this...for multi selection
Re: How to copy data from one node to another or fromone table to another table

AppleScript Studio - Table View Questions

Hello Apple Discussions --
I am trying to figure out how to do two things with a table view that has one row in it:
1. Run a piece of code on each row's information. In this case, each one of the rows will have a POSIX path in it.
2. Put the number of rows in a variable.
I am using the "Drag and Drop" sample code from the developer tools. Thanks in advance for anyone's help!

Hi Przemek,
As the DO_INIT_CONTEXT method exists in the IMPL Class and as you said that BTADMINH is available in the view, you can access it directly like this.
DATA: lr_btadminh TYPE REF TO if_bol_bo_property_access,
ls_atadminh TYPE CRMST_ADMINH_BTIL .
lr_btadminh ?= me->typed_context->btadminh->
collection_wrapper->get_current( ).
CHECK GET_PROPERTIES IS BOUND.
lr_btadminh->GET_PROPERTIES ( IMPORTING es_attributes = ls_atadminh)
Filter your internal table first and then populate the value node.

Multi layer table view/navigation controller hierarchy best practice

Hi,
I am new to iPad/iPhone development and wondering what the best practice for multiple layers of table views is? I understand the principle of a navigation controller providing the framework for moving up and down a list but have not yet quite got my head around if you should have one navigation controller for the whole tree or several navigation controllers.
In my app I need to have the following:
Main view -> window view showing some interactive elements (picker, buttons etc.)
Setup view -> Hierarchy managed by nav controller/table views
The setup view needs to manage the following hierarchy...
- Level A:
- Global app variables (one table view)
- Level B Items (table view showing list of items at belonging to Level B)
- Level B Item 1 (table view showing list of items at level C belonging to level B item 1)
- Level C Item 1 (table view showing list of items at level D belonging to level C item 1)
- Level D Item 1 (table view showing list of items at level E belonging to level D item 1)
- Level E item (table view for properties of item at Level E)
- Level D Item n
- Level C Item n
- Level B Item n
Each level in this has some properties and then a list of child items.
What would be the best way of structuring this? I would assume that creating a class that extends a view controller for each level is a given but what about the control of the navigation? Should this be handled by one navigation controller or one per level? I think I know the right answer but have not seen a neat way of implementing
I think I am also best off having each level in it's own xib but, once again, am not 100% sure that this is the best design pattern.
Many thanks in advance for any help/pointers!
Cheers

Hi Julian,
I have struggled with the same questions you are addressing. On a previous project we tried to model based on packages, but during the course of the project we encountered some problems that grew overtime. The main problems were:
1. It is hard to enforce rules on package assignments
2. With multiple developers on the project and limited time we didn't have time to review package assignment
3. Devopelers would click away warnings that an object was already part of another project and just continue
4. After go-live the maintenance partner didn't care.
So, my experience is is that it is a nice feature, but only from a high level design point of view. In real life it will get messy and above all, it doesn't add much value to the development. On my neew assignment we are just working with packages based on functional area and that works just fine.
