CLOSED- Recursive Tree with Recursive Table and seperate Relationship table

Hi All,
I am trying to achieve a adf recursive tree with recursive table but relationships are stored in separate table like
Table A:
id name
1 Val1
2 Val2
3 Val3
4 Val4
5 Val5
Table B:
fromid rel_type toid
1 Parent-of 2
2 Parent-of 3
3 Parent-of 4
1 Parent-of 5
I did lots of reading from forum and various posts but couldn't make it work.
Any suggestion what would be best approach and/or sample code for this ?
Thanks

I think that you can get this done by defining a VO that fetches all the top level nodes and have a view link to a VO that has all the details with a self recursive viewlink
Query for the top level
Select A.id, A.name
from A
Where A.id not in (select disctinct toid from B)
Query for the detail level
Select A.id, A.name, B.from, B.to
from A,b
where a.id = b.toid;
ViewLink is going to be:
detail.from=master.id
and another viewlink for the recursive relationship
detail.from=detail.to

Synchronize recursive tree with edit form

Hi,
I am trying to synchronize recursive tree with form, i have followed this post exactly Oracle ADF Developer: ADF - Synchronizing form with recursive tree
the first level of the tree works but the inner levels does not.
I am using JDEV 11.1.2.3

Resolving loops in a star schema with 5 fact tables and 6 dimension tables

Hello
I have a star schema, ie 5 FACT tables and 7 dimension tables, All fact tables share the same dimension tables, some FACT tables share 3 dimesnsions, while other share 5 dimensions.
I did adopt the best practices, and as recommended in the book, I tried to resolve them using Context, as it is the recommended option to Alias in a star schema setting. The contexts are resolved, but I still have loops. I also cleared the Multiple SQL Statement for each context option, but no luck. I need to get this resoved ASAP

Hi Patil,
It is not clear what exactly is the problem. As a starting point you could set the context up so that it only covers the joins from fact to dimension.
Fact A, joins Dim 1, Dim 2, Dim 3, and Dim 4
Fact B, joins Dim 1, Dim 2, Dim 3, Dim 4 and Dim 5
Fact C, joins Dim 1, Dim 2, Dim 3, Dim 4 and Dim 6
Fact D, joins Dim 1, Dim 2, Dim 3, Dim 4 and Dim 7
Fact E, joins Dim 1, Dim 2, Dim 4 and Dim 6
If each of these are contexts are done and just cover the joins from fact to dim then you should be not get loops.
If you could lay out your joins like above then it may be possible to specify the contexts/aliases that should work.

SQL Server 2012 Management Studio:In the Database, how to print out or export the old 3 dbo Tables that were created manually and they have a relationship for 1 Parent table and 2 Child tables?How to handle this relationship in creating a new XML Schema?

Hi all,
Long time ago, I manually created a Database (APGriMMRP) and 3 Tables (dbo.Table_1_XYcoordinates, dbo.Table_2_Soil, and dbo.Table_3_Water) in my SQL Server 2012 Management Studio (SSMS2012). The dbo.Table_1_XYcoordinates has the following columns: file_id,
Pt_ID, X, Y, Z, sample_id, Boring. The dbo.Table_2_Soil has the following columns: Boring, sample_date, sample_id, Unit, Arsenic, Chromium, Lead. The dbo.Table_3_Water has the following columns: Boring, sample_date, sample_id, Unit, Benzene, Ethylbenzene,
Pyrene. The dbo.Table_1_XYcoordinates is a Parent Table. The dbo.Table_2_Soil and the dbo.Table_3_Water are 2 Child Tables. The sample_id is key link for the relationship between the Parent Table and the Child Tables.
Problem #1) How can I print out or export these 3 dbo Tables?
Problem #2) If I right-click on the dbo Table, I see "Start PowerShell" and click on it. I get the following error messages: Warning: Failed to load the 'SQLAS' extension: An exception occurred in SMO while trying to manage a service.
--> Failed to retrieve data for this request. --> Invalid class. Warning: Could not obtain SQL Server Service information. An attemp to connect to WMI on 'NAB-WK-02657306' failed with the following error: An exception occurred in SMO while trying

I get this problem fixed in my PC that is an end user of the Windows 7 LAN System? Note: I don't have the regular version of Microsoft Visual Studio 2012 in my PC. I just have the Microsoft 2012 Shell (Integrated) program in my PC.
Problem #3: I plan to create an XML Schema Collection in the "APGriMMRP" database for the Parent Table and the Child Tables. How can I handle the relationship between the Parent Table and the Child Table in the XML Schema Collection?
Problem #4: I plan to extract some results/data from the Parent Table and the Child Table by using XQuery. What kind of JOIN (Left or Right JOIN) should I use in the XQuerying?
Please kindly help, answer my questions, and advise me how to resolve these 4 problems.
Thanks in advance,
Scott Chang

In the future, I would recommend you to post your questions one by one, and to the appropriate forum. Of your questions it is really only #3 that fits into this forum. (And that is the one I will not answer, because I have worked very little with XSD.)
1) Not sure what you mean with "print" or "export", but when you right-click a database, you can select Tasks from the context menu and in this submenu you find "Export data".
2) I don't know why you get that error, but any particular reason you want to run PowerShell?
4) If you have tables, you query them with SQL, not XQuery. XQuery is when you query XML documents, but left and right joins are SQL things. There are no joins in XQuery.
As for left/right join, notice that these two are equivalent:
SELECT ...
FROM   a LEFT JOIN b ON a.col = b.col
SELECT ...
FROM   b RIGHT JOIN a ON a.col = b.col
But please never use RIGHT JOIN - it gives me a headache!
There is nothing that says that you should use any of the other. In fact, if you are returning rows from parent and child, I would expect an inner join, unless you want to cater for parents without children.
Here is an example where you can study the different join types and how they behave:
CREATE TABLE apple (a int    NOT NULL PRIMARY KEY,
b varchar(23) NOT NULL)
INSERT apple(a, b)
   VALUES(1, 'Granny Smith'),
   (2, 'Gloster'),
   (4, 'Ingrid-Marie'),
   (5, 'Milenga')
CREATE TABLE orange(c int NOT NULL PRIMARY KEY,
d varchar(23) NOT NULL)
INSERT orange(c, d)
   VALUES(1, 'Agent'),
   (3, 'Netherlands'),
   (4, 'Revolution')
SELECT a, b, c, d
FROM   apple
CROSS JOIN orange
SELECT a, b, c, d
FROM   apple
INNER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM   apple
LEFT   OUTER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM   apple
RIGHT OUTER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM   apple
FULL OUTER JOIN orange ON apple.a = orange.c
go
DROP TABLE apple, orange

Multiple 'logical joins' between a fact table and one dimension table

It appears that one cannot create multiple ‘logical joins’ between a fact table and one dimension table in OBIEE using the Oracle BI Administration Tool. For example, considering a Business Model with a dimension table TIMES and a fact table FACT containing START_TIME and END_TIME, we would like to create separate logical joins from FACT to TIMES for the START_TIMEs and END_TIMEs? Obviously, the underlying foreign keys can be created, but as far as I can tell the Oracle BI Administration Tool doesn’t support this. The workaround would be to replicate the TIMES table, but that’s ugly.
I seek an alternative approach.

Try this. Create an two aliases for the TIMES dimension (Start & End) in the Physical Layer and then remove foreign key to the "Parent" Times dimension. Create the Foreign Key in the Physical Layer to the new aliases and then create the complex joins in the BMM Layer to the new aliases as well. This will allow you to present both dates within the same table in the Presentation Layer. Not the most elegant solution but it works.

Lookup Flat Table and Lookup Qualifier Table

Hi,
Can any body confirm that if I will change the type of lookup-flat type field to lookup-qualifier type field. But the structure of Lookup Flat table and Lookup Qualifier table will be the same then the Java code written to populate the lookup-flat type field will work without any changes with its new type (lookup-qualifier).
Right now when I run the code after the above said changes, no error comes but no values is assigned to that field.
Another way to ask this question, can a simple Qualifier Lookup table(without having any qualifier type field) be used as like Lookup flat table.
I would appreciate if any body can help me in this regard ASAP.
Regards
Shahid Nadeem

Hi Alok,
I think this Qualifier importing after main table import is quite trickier that you estimate.
1)Map all the fields of qualified table with source fields whther they are qualifiers or non-qulaifiers.
- we will only be able to view the Non Qualifier field in the qualified table.
2)Now the main step is when you finish all field and value mapping there will be also a Target field name on your qualified table with values of display field. this field must be mapped to a source field to import qualified table. do value mapping also.
- This target field is the linkup field you are talking abot i feel, and it is viewed only in the main table and, as i have only on one non- qualifier this will not be a combination of any display fields.
3)I am not abl eto see the Non -Qualifier in my main table
So how do i proceed.
Kindly guide
Thanks

How to provide joins between oracle tables and sql server tables

Heterogeneous joins do not exactly scale and performance can be severely degraded by network speed and b/w availability. And there is nothing you can do in the application and database layers to address performance issue at the network level in this case - your code's performance is simply at the mercy of network performance. With a single glaring fact - network performance is continually degrading. All the time. Always. Until it is upgraded. When the performance degradation starts all over again.
If the tables are not small (few 1000 rows each) and row volumes static, I would not consider doing a heterogeneous join. Instead I would rather go for a materialised view on the Oracle side, use a proper table and index structure, and do a local database join.

DB Adapter inserting data in to regular tables and LOG / History tables

I have a requirement of reading a XML file using the File Adapter and inserting into Data base.
I'm using File Adapter --> Mediator --> DB Adapter
When I insert the data I have to insert in to regular tables and LOG / History tables the same data.
There is a foreign key relationship with regular table and History table. How to insert in to both tables (regular and LOG / History)?
Thanks in advance

while configuring the adapter, you need to create the relationships between the two tables, while importing the tables, import the two tables...

Diference b/w normal tables and pl/sql tables

They are memory structures that store data and go away when your program stops running - essentially arrays or "tables" in other programming languages. "normal" ("heap") tables are stored on disk and are persistant - they store data permanently.
already we have tables then what is the purpose of pl/sql tables.Collections are used to store data temporarily in memory, when it will be accessed shortly or repeatedly for fast access. This works best with smaller data sets because if you store too much data in a collection you can run out of memory to use
what are the advantages of pl/sql tables compare nor mal tables.Collections give you faster access to data you need to read more than once during the same application. They work well for fast lookups and for smaller data sets can improve program performance slightly with the use of the bulk collect and forall PL/SQL operators under the right conditions.

To reset the timeout or delay values, use the ip dhcp snooping database timeout seconds or the ip dhcp snooping database write-delay seconds global configuration command.To renew the database, use the renew ip dhcp snooping database privileged EXEC command.

Inner join on Buffred table and not buffered table.

Hi guys,
   Can you suggest me how can i write select query using inner join on buffered table and not buffered table. i written like this. is it right?
SELECT a~vbeln
         a~vkorg
         a~kunnr
         a~kunag
         a~wadat_ist
         a~xblnr
         b~bukrs
   FROM likp AS a INNER JOIN tvko AS b
    ON avkorg = bvkorg BYPASSING BUFFER
INTO TABLE itab_likp
WHERE vbeln = s_vbeln.
Thanks.
RAJ

Hi Raj ,
Please find below my Commentes :
1. When you use "Bypassing buffer" clause in Select statement , the data what is there in the buffer of application sever is always ignored and Read is performed from the Physical database always. This Clause is advisable where you require realtime data (Not recommended generally in reporting)
2. It is advisable that you should not use small table in the innerjoin with big table. In the query you have written there are 2 tables:- LIKP and TVKO outof which TVKO is a master table containing very few records than LIKP (Contains huge data for Delivery header).
So my recommendation will be : -
1. Eliminate the "Bypassing Buffer" clause from your Query
2. Break the select query into 2 select queries breaking the join and with some ABAP logic populate the Internal table "itab_likp".
This will be optimum way inwhich you can write the select query for your senarion. Also Ensure that indexes are being used for better selectivity.
Hope this will help to you.

Nikhil

Difference between client dependent table and client independent table

hi all,
i m new in sap pls tell me the difference between client dependent table and client independent table.
tell me in detail.
thanks and regards
vikas saini

HI
Client dependent Means if you create that data in one client is limited to that client only and it is not accessable in other clients
Like SAP SCRIPTS and STD texts data
where as Client Independent means the data if you create in one client that is available in that as well as in other clients
Like SMARTFORMS, All dictionary Objects data and Repository objects data like Programs, Fun modules, tables etc..
There is no specific reason behind why scripts are client dep[endent and smartforms are client independent!!!
As for SAP -- Scripts are called client dependent because if you create client in say,200 it would be available in that only.If you want to test the script in client 300 then it won't be there,you will have to go to transaction se71 in 300 .Then Utilities-> Copy from client.Give the source as 200 & form name(i.e. script name) & copy.
Few more reasons why....? Please read below:
SAPscript technology is based on a mainframe product from the 1980s.SAPscript forms have always been -- under the hood -- relatively passive objects, with minimal embedded logic. These forms were designed to be driven and controlled by ABAP programs, much in the way ABAP programs read in database tables to produce reports;
if you ever download a SAPscript form (e.g., via utility program RSTXSCRP), and look at the portable text file it produces you'll see what I mean.
Many text objects (e.g., invoice header texts) are bound directly to documents which are client-dependent, so it makes sense for these text objects to also be client-dependent. From a complexity standpoint, SAPscript forms are close enough to these text objects where I can see how it made sense at the time to make them client-dependent too.

JOINING local table and DB Link table performance

Hellou everybody,
can somebody tell me how it is work in Oracle DB when you want to join some local table and DB Link table for example:
Select a.col1, b.col2
from local_table a , remote_table@dblink b
where a.key = b.key;
and when I use DRIVING_SITE hint and the all data from remote table is transforming (pushing) into my DB (in some temporar space), it will transform although Indexes from remote table?
So when I use some JOINS, this joins will be fast enought? Will they using remote table indexes to query the data or not?
Thank you for response.
