Link view to z-table

Hi,
the maintenance view V_QPGR_KAT is used in customising. We would like to add some fields to this view so I have been asked is the following possible....
Create a new z-view which links V_QPGR_KAT and the new z-table. I can't see how to do this without creating a new view which would be a copy of V_QPGR_KAT with the new z-table added to it.
Is there another way?
Thanks.

Hi,
u can use the Tcode QS41 Select the appropriate catalog and press enter then click on New entries button.
With regards,

Maintaince view of a table

Hi All,
I have created a custom table. While I display data for this table I need one extra field (from some other table) in the display. That extra field is not in the include structure.
Any pointers...
Thanks in advance.
Neerja

Hi,
Checkout if there is any link between the custom table and the other table from which you want to add one more field and proceed with creation of database view or maintainance view.
Cheers!!

Creation of view on single table?

Hi Team,
I have a requirement like for creaation of view on single table (QMEL) in SAP ECC side...
Note: in this table i need 2o fields only....not all fields.
First can we create view on single table?
if 'Yes' can any one tell , How we can creat view on single table?
While creation of view we have four options..
1)Data base view
2)Projection View
3)Maintanace view
4)Help view
in these four options which tyep of view we can choose for creation?
please can any one suggest me and do the need full..
i am waiting your responce...

I quickly skimmed the links provided by others; and in my short discussions with DBA friend of mine; and other sources... partition should be based on user needs, sql server resources, and partition maintenance time.
Lets say you have 50 regions and 1) partition the data by region, AND 2) place each partition on a different disk, and 3) i am in Texas and only query data in the Texas region then performance will be increased because I am not scanning through the other
49 regions.
If you have temporal data (dependent on time - like say financial reports that are sent to the SEC) - the partitions are by time: 1) data from last 13 months is stored on SSD, 2) data 13 months - 3 years old is on HDD, and 3) data >3 years old is stored
on compressed HDD. (i say 13 months so you have an entire year and month to date) --- accountants can get the current data VERY quickly, project managers who need to see a 3 year trend will not have to wait long, and when the SEC calls, who cares?,
the reports can be queued and generated at night when no one is working.
I see partitions are giving the users the least amount of data to query which speeds their results.

Creation of Database View on different tables

Hi All,
I want to create a Data base View on 5 Tables(LIKP,EQUI,MARA,QMFE,QMUR).
My Question is i will create a View without any selections and the View is based on tables Link (Primary&foreign keys) only.
Once my View is ready i will pull the data from SAP R/3 based on Infopackage selection.
Is my approach is correct?or i need to mention any thing while creating the View itself?
Waiting for reply and your points are assured.

Error while trying to view the details table from Show/Hide icon

What we are having is two tables, Outer and Inner, having Outer VO and Inner VO,outer VO is linked with inner VO. Now when I am trying to view the inner table
through Show/Hide icon to see the details of the table ,I am getting an error like ...
The record with primary key values {2280} could not be found in view object MisForecastHeadOfiiceAM.InnerTableVO_OuterInnerVL_InnerTableVO.
I want to know how this error can be resolved

Hi Abdul,
We are not getting error while searching. As said earlier
While search for the first time > We could see proper results in out table and Even show/hide is working fine and display correct data in Inner table
When searching for the second time with different criteria > We could see proper results in outer table and on clicking show/hide (to view inner table data), we are getting error.
The record with primary key values {2280} could not be found in view object AM.ViewLinkVL_InnerTableVO
From the error message, we found that its trying to get the row (of inner table) pertaining to first search results and not for the outer table row in context to second search results.

Can we write a join on a view and a table

Hi all,
can we write a join on a view and a table. i got the requirement from my functional people about the following one
Select CAUFV-AFUNR, CAUFV-AUART, AFVC-VORNR, CAUFV-FTRMI, CRHD-ARBPL
into <ProOrd>, <OrdTyp>, <Opt>, <RelDat>, <WorCen>
from CAUFV, AFVC, CRHD
where CAUFV-WERKS = plant in selection screen
and CAUFV-AFUNR = production order in selection screen
and CAUFV-AUART = production order type in selection screen
and CAUFV-FTRMI = range of release date in selection screen
and CAUFV-AUFPL = AFVC-AUFPL
and AFVC-ARBID = CRHD-OBJID
and CRHD-OBJTY = A
here CAUFV is a view and CRHD and AFVC are transperent tables.
please tell me any feasible solution for this..
Thanks in Advance..

Embed E-mail Link in ADF Bound Table?

I've got a table on a JSP that includes an e-mail address. I'd like to put an e-mail link right in the table for the address, so the user can just click on it and launch their email. Is this possible? If so, what's the syntax? Nothing I've tried comes out right.

Great idea, but unfortunately, it doesn't seem to work. It appears that the browser is not interpreting it correctly. Here's what I have in my SQL Statement:
'Send E-Mail'
When I run it, the application shows that text literally in the grid. If I view source from the browser, I see:
<td><a href="mailto:[email protected]">Send E-Mail</a> </td>
I've tried substituting in the SQL the ASCII characters (< for example) and it just renders that as literal text too.
Any other ideas?

[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.

(A is Prod, B is CpuSocket)
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.

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.

Is there a way to view all the table names in a certain schema?

Is there a way to view all the table names in a certain schema?

SELECT table_name FROM user_tablesThat won't do much good given this piece of information:
i am trying to finish a lab for school but i don't know what tables are in my
professor's schema. The appropriate solution is
SELECT table_name
FROM all_tables
WHERE owner = 'PROFESSOR_YAFFLE'
/This will show the names of the tables which Prof. Yaffle has granted to us.

View dependent on table

hello gurus
i'm running oracle 8.1.7.4. . we can describe a view but I need to know how can we find out on which tables a view is based on and what 's it's definition
Thanks

Hi,
>>I need to know how can we find out on which tables a view is based on
In addition, you can also make use of the *_DEPENDENCIES data dictionary views in order to list informations about direct dependencies and dependency among some schema objects.
e.g:
LEGATTI@ORACLE10> create table t1 (id1 number);
Table created.
LEGATTI@ORACLE10> create table t2 (id2 number);
Table created.
LEGATTI@ORACLE10> create view my_view as select id1,id2 from t1,t2;
View created.
LEGATTI@ORACLE10> select * from user_dependencies where name='MY_VIEW';
NAME        TYPE    REFERENCED_OWNER   REFERENCED_NAME   REFERENCED_TYPE
MY_VIEW     VIEW    LEGATTI            T1                TABLE
MY_VIEW     VIEW    LEGATTI            T2                TABLE          Cheers

View, Clustur & Pooled Table

Hi,
I have few questions on the above topics.
How can we retreive data from View , Clustur & Pooled Table using Select statements.
If possible can you explain me with an example.
what kind of data can we retreive from them . for example BSEC - how can we use it .
Thank you in advance.
Ry

hi,
You can access them using SELECT statements, you CAN NOT use joins though.
For example, BSEG is a cluster table.
report znave_0003 .
data: ibseg type table of bseg with header line.
parameters: p_bukrs type bseg-bukrs.
select * into table ibseg from bseg
up to 100 rows
where bukrs = p_bukrs.
loop at ibseg.
write:/ ibseg-bukrs, ibseg-belnr.
endloop.
to retrieve the data from a view....
Declare the internal table with the type of View.
Data : itab type table of zview001.
or write select query as
select * from zview001 into corresponding fields of itab.
Also you can uncheck the Unicode checks active (checkbox) in the program attributes.
{When you check that unicode checkbox, you should use an internal table without a header line. Instead you should declare a work area)
Hope it helps...

View on cluster table

hi all,
I am trying to create a view for the tables bkpg and bseg.but am unable to as the error is "bseg is cluster table".
can't we create view for cluster table. if can, how

You cannot create a view because BSEG is in a cluster table
For this reason SAP has provided some "secondary index" tables, look for :
     BSAD     Accounting: Secondary Index for Customers (Cleared Items)
     BSAK     Accounting: Secondary Index for Vendors (Cleared Items)
     BSAS     Accounting: Secondary Index for G/L Accounts (Cleared Items)
     BSID     Accounting: Secondary Index for Customers
     BSIK     Accounting: Secondary Index for Vendors
     BSIM     Secondary Index, Documents for Material
     BSIS     Accounting: Secondary Index for G/L Accounts

View on DB Table

I want to create a view on DB Table eg CSKS. Can anyone show me how to do this or Show me where I can find information to create view on DB Table.
Thanks.

hi anil,
In database theory, a view is a virtual or logical table composed of the result set of a query. Unlike ordinary tables (base tables) in a relational database, a view is not part of the physical schema: it is a dynamic, virtual table computed or collated from data in the database. Changing the data in a table alters the data shown in the view.
The result of a view is stored in a permanent table whereas the result of a query is displayed in a temporary table.
Views can provide advantages over tables;
They can subset the data contained in a table
They can join and simplify multiple tables into a single virtual table
Views can act as aggregated tables, where aggregated data (sum, average etc.) are calculated and presented as part of the data
Views can hide the complexity of data, for example a view could appear as Sales2000 or Sales2001, transparently partitioning the actual underlying table
Views take very little space to store; only the definition is stored, not a copy of all the data they present
Depending on the SQL engine used, views can provide extra security.
Views can limit the exposure to which a table or tables are exposed to the outer world
Just like functions (in programming) provide abstraction, views can be used to create abstraction. Also, just like functions, views can be nested, thus one view can aggregate data from other views. Without the use of views it would be much harder to normalise databases above second normal form. Views can make it easier to create lossless join decomposition.
Rows available through a view are not sorted. A view is a relational table, and the relational model states that a table is a set of rows. Since sets are not sorted - per definition - the rows in a view are not ordered either. Therefore, an ORDER BY clause in the view definition is meaningless and the SQL standard (SQL:2003) does not allow this for the subselect in a CREATE VIEW statement.
Read-only vs. updatable views
Views can be read-only or updatable. If the database system is able to determine the reverse mapping from the view schema to the schema of the underlying base tables, then the view is updatable. INSERT, UPDATE, and DELETE operations can be performed on updatable views. Read-only views do not support such operations because the DBMS is not able to map the changes to the underlying base tables.
Some systems support the definition of INSTEAD OF triggers on views. This technique allows the definition of logic that shall be executed instead of an insert, update, or delete operation on the views. Thus, data modifications on read-only views can be implemented. However, an INSTEAD OF trigger does not change the read-only or updatable property of the view itself.
Advanced view features
Various database management systems have extended the views from read-only subsets of data. The Oracle database introduced the concept of materialized views, which are pre-executed, non-virtual views commonly used in data warehousing. They are a static snapshot of the data and may include data from remote sources. The accuracy of a materialized view depends on the frequency or trigger mechanisms behind its updates. DB2 provides so-called materialized query tables (MQTs) for the same purpose. Microsoft SQL Server, introduced in the 2000 version, indexed views which only store a separate index from the table, but not the entire data.
Equivalency:
A view is equivalent to its source query. When queries are run against views, the query is modified. For example, if there exists a view named Accounts_view and the content is:
accounts view:
SELECT name,
       money_received,
       money_sent,
       (money_received - money_sent) AS balance,
       address,
FROM table_customers c
JOIN accounts_table a
    ON a.customerid = c.customer_id
The application would simply run a simple query such as:
Sample query
SELECT name,
       balance
FROM accounts_view
The RDBMS then takes the simple query, replaces the equivalent view, then sends the following to the optimiser:
Preprocessed query:
SELECT name,
       balance
FROM (SELECT name,
               money_received,
               money_sent,
               (money_received - money_sent) AS balance,
               address,
          FROM table_customers c JOIN accounts_table a
               ON a.customerid = c.customer_id        )
From this point on the optimizer takes the query, removes unnecessary complexity (i.e. it is not necessary to read the address, since the parent invocation does not make use of it) and then sends the query to the SQL engine for processing.
