Definition of table built on a view

Hi ,
I am using a table created on a view, i can get the structure of a view from user_views.
But where can i get the structure for the table built on a selected columns of the view ?? I am looking for structure as it was defined while creating.
Thanks.

Hi,
Welcome to the forum!
As Alex said, "DESC table_name" shows all of the most important features. (If the tabel was created using "CREATE TABLE table_name AS ...", which I believe is what you mean), then that will probably be everything.
DESC gets its information from the data dictionary, which includes the views
user_tables
user_tab_columns
user_constraints
user_cons_columns
user_views
and others. You can query these views, which contain information about you own tables and views, or the correpsonding "all_" views (all_tables, all_tab_columns, ...) whcih also include tables in other schemas that you are permitted to use.
All of this reflects the state of the table at the present time. I don't think information about the table "as it was defined while creating" is kept anywhere in the data dictionary, so if the table was changed, you might be out of luck.

Select data from all the table names in the view

Hi,
"I have some tables with names T_SRI_MMYYYY in my database.
I created a view ,Say "Summary_View" for all the table names
with "T_SRI_%".
Now i want to select data from all the tables in the view
Summary_View.
How can i do that ? Please throw some light on the same?
Thanks and Regards
Srinivas Chebolu

Srinivas,
There are a couple of things that I am unsure of here.
Firstly, does your view definition say something like ...
Select ...
From "T_SRI_%"
If so, it is not valid. Oracle won't allow this.
The second thing is that your naming convention for the
tables suggests to me that each table is the same except
that they store data for different time periods. This would be
a very bad design methodology. You should have a single
table with an extra column to state what period is referred to,
although you can partition it into segments for each period if
appropriate.
Apologies if i am misinterpreting your question, but perhaps
you could post your view definition and table definitions
here.

How to use the TableSorter for two tables at the same view?

Hello,
I am using the TableSorter object in order to sort Dynpro tables.
Suppose I have two tables at the same view, is it possible to use it seperatly for both of them?
I assume that at the wdModifyView method I will need to catch the table that the user clicked on, yet I don't have an idea of how to do it...

Hi Roy,
Constructor of TableSorter
public TableSorter(IWDTable table, IWDAction sortAction, Comparator[] comparators)
So, you have to create instance of TableSorter class for each table on the view.

MVC: Create a view which populates two (or more) joined tables in a single view table

I am beginner in MVC and I would like to create a view which populates two (or more) joined tables in a single view table as described below.
I have two tables:
1 - Bloggers: - bloggerID (int);
                    - bloggerName (string)
2 - Blogs: - blogID (int);
bloggerID (int);
                - blogTitle (string);
                - blogImage (string)
A blogger can have one or more blogs while one blog must be related to only one blogger.
I would like to have a view table on my webpage as the following:
Blogger Name
Blog Title
Blog Image
Noris Gang
Virus
virus.jpg
Noris Gang
Desktops
desktop.jpg
Gauthier
Books

I'm using MVC 4 (or at least 3).
Thanks for your help.

Hello,
From your description, it is not very clear that what you mean about the View, if it means the View concept in database as SQL Server, your required view should be as below:
Create view
as
Select Bloggers.bloggerName, Bloggers.blogTitle, Bloggers.blogImage
From Bloggers join Blogs on Bloggers.bloggerID = Blogs. bloggerID
If it means the UI view in MVC concept, I suggest you could ask it on the MVC forum:

ORA-01776: cannot modify more than one base table through a join view

I have created EO based on a database view than consists of two tables, and only one is updateable.
When I try to update a row using EO, I got a following message: "ORA-01776-cannot modify more than one base table through a join view"
In Forms, this issue is resolved by setting "Query Only" property of non-updateable items to "True".
Is it possible to do something like that in ADF BC?
Thanks

Thanks for answer.
When I set "updateable" property to "Never", that attribute is protected from any change.
I'm sorry for incomplete usecase.
I have set up a list of value on that attribute, because it is a lookup field for another table and I need to get an ID from that table.
Basically, I need that attribute to be updateble for BC, but not for database.

Cannot modify more than one base table through a join view

hi guys, my current problem is that i have a datablock based on a view, now all the fields bar 1 are updateable, but this one field that is obtained through a join is displayed, the user can enter data in this field which then pupulates other fields which are required, but this specific field should not be updated. Is there an option to state this as i keep getting the error:
cannot modify more than one base table through a join view
Any help would be greatly appreciated, thanks.

the user can enter data in this field which then pupulates other fields So, using the value of "this field" you then query the rest of the fields? Can you show us the code you use to populate the rest of the fields?
but this specific field should not be updatedHave you tried setting the "Query Only" property of the field to "Yes" and the other DML properties (Ins, Upd, Del) to No?
Also, what is your Forms version?
Thanks,
Craig B-)

Issue with ADF Table bound to a View Object Iterator??

Can anyone say what would prevent an ADF table bound to a View Object Iterator from displaying all the records retrieved by the View Object Query?
I ran the query directly from sqlplus and it returned 21 rows, However when i use the same exact query in my view object and display the result in a ADF table, only 10 rows are retrieved and displayed in the table ?
Help .. Please ???

The ADF table is actually set to use 'Include Range Navigation' and to display 20 rows each time. However, only a 10 rows are retrieved and displayed and the other 10 rows are displayed as blanks with only the Table selection radio buttons in the Select Column.
e.g.
Select Data1 Data 2
o xxxxxx xxxxxx
o xxxxxx xxxxxx
o
o
o
o
The four 'o' are blanks even though there is data to be displayed.

Cannot open pdf files with Firefox's built-in pdf viewer

This just started (I think) with Firefox 37.01. This is on Win7-X64. I cannot open pdf files with the Firefox built-in pdf viewer. If I click on the file or try to open it from within Firefox, it brings up a "opening filename.pdf" message. If I select the "Open with" radio button as 'Firefox (default),' it just keeps looping on this process; it never opens. In Tools => Options => Applications, Portable Document Format (PDF) is indicated as 'Preview in Firefox.' I've never had any other PDF viewer installed on this computer. I've tried disabling all plug-ins and extensions, but it still doesn't work. I searched for solutions but haven't found any for this specific issue.
Thanks for the help.

Hello,
Have you tried, to start Firefox in safemode you can do so by following these steps
'''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
'''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
;[[Image:SafeMode-Fx35]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''

FREE3OF9 barcode font not displaying in Firefox's new built-in PDF viewer

I have a PHP web app that uses FPDF (v1.53) and the FREE3OF9 barcode font to dynamically generate a PDF which includes a barcode in it. The font is imported into the document using the FPDF AddFont method (http://fpdf.org/en/doc/addfont.htm). In versions of Firefox prior to 19, the PDF opened in a new tab, was displayed by the Adobe Acrobat plugin, and the barcode showed up perfectly fine.
Now that Firefox 19.0 is using its own built-in PDF viewer, the barcode no longer displays at all -- there's just a blank spot where it should be. It continues to display fine in IE and Chrome. How I can get the font to display correctly in the newest version of Firefox?
I understand that I can change the Action for the PDF content type to 'Use Adobe Reader' in the options, but I'd prefer to fix this so that my users don't have to change their browser settings. Or at the very least, it would be nice if they could only change the Action for PDFs originating from my site and not globally.
Thanks.

You can set the pdfjs.disabled pref to true on the <b>about:config</b> page to disable the build-in PDF viewer and use the Adobe Reader instead.

Table heading in pivot view

Hi All
I am trying to show table heading in pivot view but failed. Please help me on this
I know that can achieve in table view but looking for a solution in pivot view.
What I am lookinf for is: Pivot View
Rows ---------Measures----------
X Y (Table Heading)
col1 col2 col3 col4 col5 col6 (column names)
--- --- --- --- ---- ---- (data)
Thnaks in advance!

Ok, for example take two columns product and revenue. Consider they are 10 products.
What I have to display in report is 9 products with revenue and total revenue of those 9 products and then the 10th product and revenue and finally the grand total.
Product---Revenue
1---35
2---45
9---60
Total---140
10---70
Grand Total---210
Which can be achieved the same in pivot view (using New calculated item)
I also need to display the table headings, there I stuck with.

SQL Query with 3 tables to create a view

Hi
I have got an existing view "View_output" formed with a query which works fine:
select A,B,C,D,E,F,G,H from GTS1 where D is not null
    UNION
   select A,B,C,D,E,F,G,H from GTSN1 where D is not null;It works fine, in the output I have columns A,B,C,D,E,F,G,H
New requirement : Modify the view, by adding a new column 'I' so that the view should have
columns A through I, and no column values should be null.
This column "I" is coming from a table, say DLC
Data in DLC is a subset of the original view "View_output"and DLC have the foll.columns:
("View_output" is a datablock source for a form and only selected column values are put as output in DLC
after form manipulation)
DLC is having only 5 columns -B,C,F,H,I
When I give:
(select A,B,C,D,E,F,G,H,NULLfrom GTS1 where D is not null
    UNION
   select A,B,C,D,E,F,G,H,NULL from GTSN1 where D is not null)
UNION
select NULL,B,C,NULL,NULL,F,NULL,H,I
    from
    DLC where I IS NOT NULL;It UNIONS all required rows in the 3 tables but columns A,D,E,G are NULL, but how can I get
data in these columns?

Hi arun thats not the real isue..
I have corrected the second code now, it was a typo from my side..
all three tables already have 9 columns selected..
The view created from GTS1 and GTSN1 is constantly changing
There is no way to add column 'I' to any of these above tables
The view is the input to a form..User ticks a tickbox corresponding to records needed by them (These are the columns in the original view mentioned above)..and based on certain logic,only selected columns are now inserted/updated into the output table through the form..this is the table DLC
Now they want to insert a new data(free text) through the form, this field correspond to each record in the form ;this is supposed to be column 'I'(not designed yet)..
this is not there in the original input tables selected for the view...But then I added this column to the output table DLC (Cant think of any other method) so that column I can also get combined in the view.
Now what I want is recreate the view through,
create or replace view statement.
the view should effectively pull data from 3 tables .
The relation between 3 tables :
DLC is a subset of GTS1 and GTSN1
but may also contain data which is not in union of GTS1 and GTSN1
Only field I need from DLC is field 'I', and that too if the data is there in the union of GTS1 and GTSN1

Table Operator Vs Materialized View Operator

Hi All,
Could you please give the differences between Table Operator and Materialized view Operator in Oracle Warehouse Builder 11g.
Regards,
Subbu

Below an extract of my notes of the Materialized view. The complete notes are here :
http://gerardnico.com/wiki/dw/aggregate_table
=====Notes=====
Materialized views are the equivalent of a summary table. (Materialized views can be also use as replica).
In a olap approach, each of the elements of a dimension could be summarized using a hierarchy.
The end user queries the tables and views in the database. The query rewrite mechanism in a database automatically rewrites the SQL query to use this summary tables.
This mechanism reduces response time for returning results from the query. Materialized views within the data warehouse are transparent to the end user or to the database application.
This is relatively straightforward and is answered in a single word - performance. By calculating the answers to the really hard questions up front (and once only), we will greatly reduce the load on the machine, We will experience:
* Less physical reads - There is less data to scan through.
* Less writes - We will not be sorting/aggregating as frequently.
* Decreased CPU consumption - We will not be calculating aggregates and functions on the data, as we will have already done that.
* Markedly faster response times - Our queries will return incredibly quickly when a summary is used, as opposed to the details. This will be a function of the amount of work we can avoid by using the materialized view, but many orders of magnitude is not out of the question.
Materialized views will increase your need for one resource - more permanently allocated disk. We need extra storage space to accommodate the materialized views, of course, but for the price of a little extra disk space, we can reap a lot of benefit.
Also notice that we may have created a materialized view, but when we ANALYZE, we are analyzing a table. A materialized view creates a real table, and this table may be indexed, analyzed, and so on.
Success

Problem occured when create a tree table for master-detail view objects using SQL queries?

I am programming a tree table for master-detail view objects using SQL queries and these 2 view objects are not simple singel tables queries, and 2 complex SQL are prepared for master and view objects. see below:
1. Master View object (key attribute is SourceBlock and some varaible bindings are used for this view object.)

3. I create a view link to create master-detail relationship for these 2 view objects.
masterview.SourceBlock (1)->detailview.SourceBlock (*).
4. I create a tree table using these 2 view objects with master-detail relationship.
When I set default value for variable bindings of these 2 view objects and the matching records exist, tree table can work well. I can expand the master row to display detail row in UI.
But I need to pass in dymamic parameter value for variable bindings of these 2 view objects, tree table cannnot work again. when I expand the master row and no detail row are displayed in UI.
I am sure that I pass in correct parameter value for master/detail view objects and matching records exist.
Managed Bean:
        DCIteratorBinding dc = (DCIteratorBinding)evaluteEL("#{bindings.MasterView1Iterator}");
        ViewObject vo = dc.getViewObject();
        System.out.println("Before MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        System.out.println("Before MasterView1Iterator ShiftModeCode="+ vo.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo.executeQuery();
        System.out.println("MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        DCIteratorBinding dc1 = (DCIteratorBinding)evaluteEL("#{bindings.DetailView1Iterator}");
        ViewObject vo1 = dc1.getViewObject();
        System.out.println("Before DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
        System.out.println("Before DetailView1Iterator ShiftModeCode="+ vo1.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo1.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo1.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo1.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo1.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo1.executeQuery();
        System.out.println("after DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
5. What's wrong in my implementation? I don't have no problem to implement such a tree table if using simple master-detail tables view object, but now I have to use such 2 view objects using complex SQL for my requirement and variable bindings are necessary for detail view object although I also think a bit strange by myself.

Hi Frank,
Thank you and it can work.
public void setLowHighSalaryRangeForDetailEmployeesAccessorViewObject(Number lowSalary,
                                                                          Number highSalary) {
        Row r = getCurrentRow();
        if (r != null) {
            RowSet rs = (RowSet)r.getAttribute("EmpView");
            if (rs != null) {
                ViewObject accessorVO = rs.getViewObject();
                accessorVO.setNamedWhereClauseParam("LowSalary", lowSalary);
                accessorVO.setNamedWhereClauseParam("HighSalary", highSalary);
            executeQuery();
but I have a quesiton in this way. in code snippet, it is first getting current row of current master VO to determine if update variables value of detail VO. in my case, current row is possibly null after executeQuery() of master VO and I have to change current row manually like below.
any idea?
            DCIteratorBinding dc = (DCIteratorBinding)ADFUtil.evaluateEL("#{bindings.SSForecastSourceBlockView1Iterator}");
            ViewObject vo = dc.getViewObject();

            vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
            vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
            vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);

Inserting into a doubly nested table through an object view

Can anyone give me an example of an INSTEAD OF trigger that will mediate an INSERT into a doubly nested table of an Object View? Is there syntax that will allow it?

Here's some code to demonstrate. Note that relational tables, not an object table, are used to store object instances:
create or replace type TInnerNestedTable
is table of varchar2(20)
create or replace type TOuterNestedTable
is table of TInnerNestedTable
create or replace type TMyObject
is object
     id     varchar2(20)
,     tab     TOuterNestedTable
create
table     T_MY_OBJECT
     id          varchar2(20)     not null
