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.

View a single table-row as multiple rows in a GridControl

Hi,
is it possible to distribute the entries of a single row of a table/RowSetInfo over multiple lines of a GridControl?
I've seen an example on the Internet (http://www2.gol.com/users/tame/swing/examples/JTableExamples4.html) which does this without database connection but it seems as if it's necessary to replace the default JTable, TableModel and UI by customized ones. As far as I've seen it's not possible to replace the JTable which is used by a GridControl? So is there any other way to do this? (A modification of the JTable-UI itself doesn't suffice as the JTable yields wrong row- and column-numbers on mousclick-events and therefore the components of the second row are not enabled properly).
Thanks in advance

You wont be able to replace the JTable. But you can change all the attributes on the internal table which the grid uses (see getTable() method). The datamodel for the grid is impemented by oracle.dacf.control.swing.GridDataSource. You can possibly extend this class. You can also change the Table column model and the renderers used by the Table.

Could you expain how the mapping between cell renderer and the table (row, col) is done in the extended JTable - which class ?.

Creation of View from Mutiple Tables (Union of result sets)

Hi,
I have started working on Information Steward very recently and Im working on creating some profiling rules in Data Insight.
I’m working on bringing data in two tables together to apply some common rules, I have tried view option but I’m not sure how to create the views as below without joins.
View should have common columns from Table1 and Table2 so I can perform below rules.
Check uniqueness of primary key column across both the tables. Like Id – Unique in view below
Combination of two different columns should be unique in both the tables. Like First name + Last Name Unique in view
I would like to create a view which is can be done using Aggregator in Information PC and Merger in BODS.

Please let me know you thoughts on how this can be achieved in SAP IS

This is not possible in IS. You'll have to create a view at db level. Or merge all data into one table, using DS as you say.

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.

View on a single table

Hi all,
my question is: does have any sense to use a view for a single table selection ?
I need to make a selection on a db table and I haven't any value neither for the primary key nor for any secondary index.
Can I improve the table access speed in any other way ???

Hello
But there are side effects affecting db performance or things like that if I create an index on a table?
Yes. For db-tables with creating new index:
1. increase the performance of READ-operations
2. decrease the performance of INSERT/MODIFY-operations

Hi Balaiji,
proceed as follows:
Create a structure in the dictionary called ZSTRU_USR02_F
with field1 type int4
          field3 type int4
          field3 type int4
Create a table type in the dictionary:
zusr02 line type ZSTRU_USR02_F.
Create a structure in the dictionary:
ZSTRU_USR02
with tab1 type zusr02
and tab2 type zusr02
Create a table type in the dictionary:
zttusr02 line type ZSTRU_USR02
Create a controller (table.do) in a BSP-application
Add the controller class to this controller.
Add a attribute (table) instance public type zttusr02
redefine method do_request, add the following coding:
FIELD-SYMBOLS: <fs_tab> LIKE LINE OF table,
                 <fs_row> TYPE zstru_usr02_f.
DATA: lirv_view TYPE REF TO if_bsp_page,

                 iterator       = "<%=controller%>"
                 footerVisible = "FALSE"
                 encode         = "TRUE"
                 width          = "100%"/>
    </htmlb:form>
</htmlb:page>
</htmlb:content>
Go back to your controller class. Add the interface IF_HTMLB_TABLEVIEW_ITERATOR
Implement the method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS
DATA: lwa_column LIKE LINE OF p_column_definitions.
* Column 1
CLEAR lwa_column.
lwa_column-columnname          = 'TAB1'.

lwa_column-tooltipheader       = 'Tooltip Column 1'.
lwa_column-width               = '50%'.
lwa_column-wrapping            = 'FALSE'.
lwa_column-horizontalalignment = 'LEFT'.
lwa_column-verticalalignment   = 'MIDDLE'.
APPEND lwa_column TO p_column_definitions.

lwa_column-horizontalalignment = 'LEFT'.
lwa_column-verticalalignment   = 'MIDDLE'.
APPEND lwa_column TO p_column_definitions.
Implement the method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START and add:
DATA: lr_tview   TYPE REF TO cl_htmlb_tableview.
FIELD-SYMBOLS: <fs_row> LIKE LINE OF table.
ASSIGN p_row_data_ref->* TO <fs_row>.
CASE p_column_key.
    WHEN 'TAB1'.
      CREATE OBJECT lr_tview.

      lr_tview->footervisible = ''.
      lr_tview->width = '100%'.
      p_replacement_bee = lr_tview.
    WHEN 'TAB2'.
      CREATE OBJECT lr_tview.
      lr_tview->id = p_cell_id.
      GET REFERENCE OF <fs_row>-tab2 INTO lr_tview->table.
      lr_tview->footervisible = ''.
      lr_tview->width = '100%'.
      p_replacement_bee = lr_tview.
ENDCASE.
With this you get a table in a table. Now if you create a second iterator you'll be able to adjust the apperance of the inner table, as well as you can add column headers.
Hope that helps.

Creation of SAP Query in SQ02 with Single Table With Condition

Hi All,
I want to Create SAP Query in SQ02 using single Table MCHA.
ii) I dont want all entries of MCHA Table I mean , I have to apply some Condition on this Table.
i.e Suppose I am having actual data in MCHA table is like this for Material M1.
Plant    Material   Batch   BatchCreationdate
P1          M1         B1       20.06.2007
P2          M1         B1       04.05.2009
P3          M1         B1       04.05.2009
But I want the Output of SAP Query is like this:
   Material   Batch   BatchCreationdate
      M1         B1       20.06.2007
That is irrespective of Plant if Material & Batch are equal ---> 1st record with Lowest date shoud get at the output.
Please help me How write the code on single table in the SAP Query.
Thanks,
Kiran Manyam

Hi,
Your query should be like this:
Select MATNR CHARG HSDAT
from MCHA
into table t_mcha
where matnr = Materlal number from selection screen.
The structure of t_mcha should contain the fields that you select.
Then sort the table by date ascending
Sort t_mcha by HSDAT.
Hope this solves your problem.
Thanks,
Sowmya

Creation of view and use it as internal table

dear community,
My questions is taht i am write a select quary in that data is very huge so that it cant inserted in to internal table(memory size of internal table) so i thing that i create aview same as data base table and when write the select quary use packsize and transfer recoerd ds in that view and use this view in my program
is above logic can work or not
also is size of view is greater than internal table memory size.

Writing the large volume to another table(which a view is just a view of a table or group of tables) is not going to solve the problem. You still have to select the data from the view(or table). Like I said in your other threads, you need to read by package size, and do something with that subset, whether it is summaring, or writeing to another system via RFC.

Creation of rows in 2 tables

I have a Create button, and below that 2 tables namely Order and Order_Item. I have created a composition association, and a view link.
How can I perform creation of rows in both tables with a single click of Create button?

You can simply use a method in your application Module / Business Services Layer which is exposed to the ADF UI and bound to your create button.
public void createRowInMultipleTables(){
   ViewRowImpl vo1Row =<SomeVO1>.createRow();
   ViewRowImpl vo2Row =<SomeVO2>.createRow();
   //set some default values if needed by vo1Row.setAttribute(<name>,<value>); etc
   <SomeVO1>.insertRow(vo1Row);
    <SomeVO2>.insertRow(vo2Row);
//commit if needed
}

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.

Adding a single table without a logical join to another table (OBIEE 10g)

Sometimes I want to just display a single table without a logical join to another table in the repository. However, everytime I move it to the Business Model and Mapping layer and perform a Global Consistency Check, it tells me that it needs a logical join and I am forced to create another table to join to it. Thus creating a dimension-fact relationship. There are times I don't need this relationship and just want to display some data. Is there anyway to get around this?
Thanks in advance!

Yes,You have to create a join.You cannot take single table to BMM layer.You can create an alias of the table.Join this alias and base table through any common column and take both tables to BMM and desired table to presentation layer.
Another way is to create a view in physcial layer.Write a select statement like
Select primary_key from Table
Where primary_key is primary key of base table.Join this view ith base table and repeat the steps defined for Alias.

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.

Creating a "Print View" of a Table on Another Sheet

Hi-
I would like to create a "print view" of a table on another sheet that already has reorganization filters applied to it. There is a template in Numbers called "Employee Schedule" that has exactly this, where the "printable" table's cells simply reference every cell in the source table on the other sheet.
I know there is a way to very quickly (i think with a dragging motion), create the references in each cell in one or two operations, as opposed to going to each individual cell and typing in the reference to the source table. I saw a post about how to do this a while back but cannot seem to locate it again
How do I do this? Thanks again for everyones help ;-)
Thanks
Matt

Hi-
Re-reading this, I don't think this answered my question. I understand how to reference a single cell, but how do you reference an entire table easily without having to go to each cell.
Thanks
Matt
Matt,
Select the first cell by clicking once on it, such that the border is highlighted. Then grab the little circle in the lower right corner of the border and drag it to the end of your table, either right or down. You can use this method to fill down or to the right. Sometimes it can be fussy, and if it refuses to behave, then you can use the alternate method, Copy and Paste. Click once on the first cell and Command-C. Shift-click the last cell and Command-V.
