Spatial index on table with object-column (and inheritance)

Hi!
Is it possible to create a spatial index on a table with an object-column (and inheritance) like this:
CREATE OR REPLACE TYPE feature_type AS OBJECT (
shape MDSYS.SDO_GEOMETRY
) NOT FINAL;
CREATE OR REPLACE TYPE building_type UNDER feature_type (
name VARCHAR2(50)
CREATE TABLE features ( no NUMBER PRIMARY KEY, feature feature_type);
[...] user_sdo_geom_metadata [...]
Then
CREATE INDEX features_idx ON features(feature.shape) INDEXTYPE IS MDSYS.SPATIAL_INDEX;
throws:
ORA-01418: specified index does not exist
Curious! :)
If I define feature_type with "NOT FINAL" option but without subtypes, I get (create index):
ORA-00604: error occurred at recursive SQL level 1
ORA-01460: unimplemented or unreasonable conversion requested
So I think besides object tables also inheritance isn't supported whith oracle spatial!?
Thanks,
Michael
ps:
We use Oracle9i Enterprise Edition Release 9.0.1.4.0 / Linux.
Solves Oracle9i 9.2 this problems?

Hi
You'll need to be on 9.2 to do this....

Suggestions for JSF table with sortale columns and Pagination

Hi,
My JSF application needs a table with sortable columns and also pagination.
Thank you.

Just add a bunch of commandlinks and/or commandbuttons at the right locations and invoke the appropriate logic in the backing bean.
You can find some useful insights in this article: [http://balusc.blogspot.com/2006/06/using-datatables.html].

Replication on the table with XMLType column and schema registered

Dear All,
Does Oracle XML DB 11g support replication for tables with schema registered?
Is there any recommended approach?
Thanks and regards,
Swapnil

Hmmmm ... I don't know if I should smile or frown with the implication that I am an OO guy :D :D
Most of my colleagues when I started working as a software engineer, treated me as too low-level because of my C background (started doing C in 1985).
In my last job, my colleagues hated my guts because I was asking them to squeeze every bit of performance out of C++ by using STL which is definitely not OO (although C++ is).
My current colleagues treat me as a DB guru (which I most definitely am not) and they overlook/forget the fact that most of them use Java libraries in their projects, that I wrote for them !
I am inclined to believe that I do not fall into any category in the end...
The only thing I am for sure - and I am proud of it - is inquisitive. I want to know everything there is about the tools I use, and so I end up spending hours and hours investigating... (Microsoft found that out the hard way when I filed 16 bug reports in 8 days when Visual C++ 6 came out ! Not that it hurt them though...)
This is where my confession ends (and my working on the XML validator starts...)

Pivot Table with Dynamic Columns and Headers

Hello,
I'm trying to pivot a table of data where the column headers will be dynamic. While I know how to pivot the table to get what I want how will I be able to pick up the table column header from the Pivot to display in the report?
For example:
Unpivoted data is Employee Code, Branch Code, Problem Code, # of Problems.
There is many records for a given Employee and Branch that I want to pivot so the Column headers are the Problem Codes and the data below is the SUM(num_problems) for that Problem.
So the data may look like this for Tech Bob, Branch NY.
Problem = LEAK, Num_problem = 5
Problem = DAMAGE, Num_problem = 2
Problem = OTHER, Num_problem = 3
Which problem codes may appear is unknown but selecting the DISTINCT(problem) across all techs gives me the column headings to use.
So if I pivot this data, I get this Row:
Tech = Bob, Branch = NY, DAMAGE = 2, LEAK = 5, OTHER = 3
So first can SSRS handle having dynamic columns? Only Tech and Branch are known and the remaining columns are dynamic based on how many Problems they worked on.
Second, how can I set the column heading in my Tablix to be the Problem Code?
Sherry

You just need to use a matrix container
Use EmployeeCode and BranchCode for row group
ProblemCode as column group and SUM([No Of Problems]) as the data expression and it will generate the columns for you based on ProblemCode values automatically.

Performance of large tables with ADT columns

Hello,
We are planning to build a large table ( 1 billion+ rows) with one of the columns being an Advanced Data Type (ADT) column. The ADT column will be based on a TYPE that will have approximately (250 attributes).
We are using Oracle 10g R2
Can you please tell me the following:
1. How will Oracle store the data in the ADT column?
2. Will the entire ADT record fit in one block?
3. Is it still possible to partition a table on an attribute that is part of the ADT?
4. How will the performace be affected if Oracle does a full table scan of such a table?
5. How much space will Oracle take, if any, for storing a NULL in an ADT?
I think we can create indexes on the attribute of the ADT column. Please let me know if this is not true.
Thanks for your help.

I agree with D.Morgan that object type with 250 attributes is doubtful.
I don't like object tables (tables with "row objects") too.
But, your table is a relational table with object column ("column object").
C.J.Date in An introduction to Database Systems (2004, page 885) says:
"... object/relational systems ... are, or should be, basically just relational systems
that support the relational domain concept (i.e., types) properly - in other words, true relational systems,
meaning in particular systems that allow users to define their own types."
1. How will Oracle store the data in the ADT column?...

Dropping a column in composite xmltype table with virtual column

Selection in table with Master Column

Hi,
can anybody explain me how selection works in table with MasterColumn (TreeByNestingTableColumn)?
I've created a table with several columns and the "master" one behaves differently from others.
First of all, leaf elements of master column are not clickable (i.e. I don't receive notification "onLeadSelect" from the table, when user clicks in the cell of leaf element of the column). With expandable elements I receive loadchildren event and can react on selection.
I'm using TextView as cell editor, will try LinkToAction, may be it will resolve situation, but it's rather workaround as solution
Second, getLeadSelection doesn't work anymore for the table - it works with indexes of top level elements only.
However onLeadSelect action brings me selected row number, which I somehow should map to the tree.
I.e. when I get "25" as selected element, I recursively traverse context node to find 25th element. Which is rather slow operation as for any selection I have to reiterate whole structure and I hope that visual appearance is similar to context element order.
May be there is simplier ways to get selected element by its index in "flat" list?
And one another strange thing: first click on the table sends me onLeadSelect "0", but highlight points to the element user clicked - not necessary first one.
Context node is "single" selection, initLeadSelect=true,
selection = 0..1 (with 1..1 setTreeSelection doesn't work - method I want to use to be able to select a node in hierarchy on my own)
all quite similar to other tables I have, which works well. Just the problems with the table, where Master Column is used.
Thank you!
Best regards,
Nick

>Valery's proposal was to perform reverse traverse from current element to root and summarize parent element indexes.
It seems to work:
in method, which sets selection I applied
// we need to know index of the element not in whole context, but in scope of table-relevant node
int index = getIndexInContext(selElement, wdContext.currentXXXElement());
IContextElement curContext = wdContext.currentContextElement();
int firstVisibleRow = curContext.getTableFirstVisibleRow();
int visibleRows = curContext.getTableVisibleRows();
if (index < firstVisibleRow || index > firstVisibleRow + visibleRows) {
curContext.setTableFirstVisibleRow(index);
and method getIndexInContext looks as:
    private int getIndexInContext (IWDNodeElement element, IWDNodeElement root) {
          int index = element.index();
          if (element == root) {
               return index;
          IWDNodeElement parent = element.node().getParentElement();
          if (parent == null) {
// do whatever you like here for error diagnostic
               myMsgMgr.reportException("Internal Error: getIndexInContext - element is not under passed root", false);
               return 0;
          // +1 - every level adds 1 (otherwise indexes of first children of hierarchy will be 0)
          return index + getIndexInContext(parent, root) + 1;

How to create a table with editable column values.

Hi everyone,
I think this is very simple but i'm not able to find how to do this. This is my requirement. I need to create a table with n columns and 1 row initially. user should be able to enter data into this table and click of a button should insert data into the data base table. Also there should be a button at the bottom of the table to add 1 row to the table.
I know how to do the insert to database, but can anyone please let me know how to create a table that allows user to enter data and how to create a add 1 row button?
Thanks in Advance!

Raghu,
Go through the ToolBox tutorial Create Page & Advanced table section of OAF Guide.
Step 1 - You require to create EO & a VO based on this EO. This EO will be of DataBase table where you want to insert the data.
Step 2 - Create a Advanced table region. (Refer this Adavanced table section for more on this)
Step 3 - Attach this VO in the BC4J component of Adavanced Table region.

Gyan

Bsp table with editable columns

Hi,
I want to create a table with some columns and include check box.
Is it possible?
I want to do this
Table :
Date   Time    Checkbox   Checkbox
Also how can i make the columns editable ?
Thank you

hello,
The basic idea would be use ITERATOR class reference in your 'Tavleview' HTMLB element
Iterator class should user interface 'IF_HTMLB_TABLEVIEW_ITERATOR', here you can modify column properties (GET_COLUMN_DEFINITIONS method) and cell properties (RENDER_CELL_START)
For your need:
RENDER_CELL_START method, example coding would be:
CASE p_column_key.
     WHEN 'Column name'.
    p_replacement_bee = cl_htmlb_checkbox=>factory(
                        id       = p_cell_id
                        _checked = p_cell_binding
                        disabled = 'X' ).
ENDCASE.
Thanks

When comparing database tables with lob columns via "Database diff" in different environments indexes are shown as different

When using "Database diff" selecting other schemas only for compare own objects are shown too!Hi!
For tables with lob columns (clob, blob, etc.) indexes with system names are automatically created per lob column.
If I am on different database instances (eg. dev/test) these system names can differ and are shown as differences, but these is a false positive.
Unfortunately there is now way to influence the index names.
Any chance to fix this in sql developer?
Best regards
Torsten

Only the Sql Dev team can respond to that question.
Such indexes should ONLY be created by Oracle and should NOT be part of any DDL that you, the user, maintains outside the database since they will be created by Oracle when the table is created and will be named at that time.
It is up to the Sql Dev team to decide whether to deal with that issue and how to deal with it.

ASSM and table with LOB column

I have a tablespace created with ASSM option. I've heard about that tables with LOB columns can't take the advantage of ASSM.
I made a test : create a table T with BLOB column in a ASSM tablespace. I succeeded!
Now I have some questions:
1. Since the segments of table T can't use ASSM to manage its blocks, what's the actrual approach? The traditional freelists??
2. Will there be some bad impacts on the usage of the tablespace if table T becomes larger and larger and is used frequently?
Thanks in advance.

Can you explain what you mean by #1 because I believe it is incorrect and it does not make sense in my personal opinion. You can create a table in an ASSM tablespace that has a LOB column from 9iR2 on I believe (could be wrong). LOBs don't follow the traditional PCTFREE/PCTUSED scenario. They allocate data in what are called "chunks" that you can define at the time you create the table. In fact I think the new SECUREFILE LOBs actually require ASSM tablespaces.
HTH!

Is this with the Travel database or another database?
If it's another database then make sure your columns
allow nulls. To check this in the Server Navigator, expand
your DataSource down to the column.
Select the column and view the Is Nullable property
in the Property Sheet
If still no luck, check out a tutorial, like Performing Inserts, ...

Hi i have created a unique index on table on 3 columns.

Hi i have created a unique index on table on 3 columns.I want to know when i have 2 records
which contain same values in 2 fields and the 3rd field contains a null
will unique index allow me to insert these records.

Robert Angel wrote:
This must be one time when null = null. ;)
regards,
Robert.Not really, it is more the case that the non-null columns need to be unique. Your second attempt failed because there was already an index entry with 'a', 'b', and the lack of a value for column c gave Oracle no way to differentiate between the two rows so they are not unique.
A subtle, but conceptually important difference. :-)

Sparse table with many columns

Hi,
I have a table that contains around 800 columns. The table is a sparse table such that many rows
contain up to 50 populated columns (The others contain NULL).
My questions are:
1. Table that contains many columns can cause a performance problem? Is there an alternative option to
hold table with many columns efficiently?
2. Does a row that contains NULL values consume storage space?
Thanks

[NULLs Indicate Absence of Value|http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10743/schema.htm#sthref725]
A null is the absence of a value in a column of a row. Nulls indicate missing, unknown, or inapplicable data. A null should not be used to imply any other value, such as zero. A column allows nulls unless a NOT NULL or PRIMARY KEY integrity constraint has been defined for the column, in which case no row can be inserted without a value for that column.
Nulls are stored in the database if they fall between columns with data values. In these cases they require 1 byte to store the length of the column (zero).
Trailing nulls in a row require no storage because a new row header signals that the remaining columns in the previous row are null. For example, if the last three columns of a table are null, no information is stored for those columns. In tables with many columns, the columns more likely to contain nulls should be defined last to conserve disk space.
Most comparisons between nulls and other values are by definition neither true nor false, but unknown. To identify nulls in SQL, use the IS NULL predicate. Use the SQL function NVL to convert nulls to non-null values.
Nulls are not indexed, except when the cluster key column value is null or the index is a bitmap index.>
My guess for efficiently storing this information would be to take any columns that are almost always null and place them at the end of the table definition so they don't consume any space.
HTH!

Oracle 11.2 - Perform parallel DML on a non partitioned table with LOB column

Hi,
Since I wanted to demonstrate new Oracle 12c enhancements on SecureFiles, I tried to use PDML statements on a non partitioned table with LOB column, in both Oracle 11g and Oracle 12c releases. The Oracle 11.2 SecureFiles and Large Objects Developer's Guide of January 2013 clearly says:
Parallel execution of the following DML operations on tables with LOB columns is supported. These operations run in parallel execution mode only when performed on a partitioned table. DML statements on non-partitioned tables with LOB columns continue to execute in serial execution mode.
INSERT AS SELECT
CREATE TABLE AS SELECT
DELETE
UPDATE
MERGE (conditional UPDATE and INSERT)
Multi-table INSERT
So I created and populated a simple table with a BLOB column:
SQL> CREATE TABLE T1 (A BLOB);
Table created.
Then, I tried to see the execution plan of a parallel DELETE:
SQL> EXPLAIN PLAN FOR
2 delete /*+parallel (t1,8) */ from t1;

Yes I did it. I tried with force parallel dml, and that is the results on my 12c DB, with the non partitionned and SecureFiles LOB column.
SQL> explain plan for delete from t1;
Explained.

The DELETE is not performed in Parallel.
I tried with another statement :
SQL> explain plan for
2        insert into t1 select * from t1;
Here are the results:

It seems that the DELETE statement has problems but not the INSERT AS SELECT !
