Need Optimized Solution to insert a table with 70 columns

Hi,
I need to insert almost 13 million records to a table which has 70 columns, and each column is a derived one.I have used the pl/sql tables to get all the 13 million records and process them, it takes 3 mins for 100 records. Any optimized solution for this.
Thanks in Advance

Hi,
This is not a direct load, i need to take all the 13 million records(single column say for eg. employee id) from a table and with which i need to get 60 different columns(say for eg., employee dept, emplyee salary) from different tables and finally insert them (13 million records with 60 columns) into the target table(employee dimension table).
Any suggestions for this.
Thanks

Sample insert into table with BLOB column

This is my first opportunity to work with BLOB columns. I was wondering if anyone had some sample code that shows the loading of a blob column and inserted into the table with a blob column.
I have to produce a report (including crlf) and place it into a blob column. The user will download the report at a later time.
Any suggestions / code samples are greatly appreciated!!!!

You can enable string binding in TopLink.
login.useStringBinding(int size);
or you could enable binding in general,
login.bindAllParameters();

ORA-07445 in the alert log when inserting into table with XMLType column

I'm trying to insert an xml-document into a table with a schema-based XMLType column. When I try to insert a row (using plsql-developer) - oracle is busy for a few seconds and then the connection to oracle is lost.
Below you''ll find the following to recreate the problem:
a) contents from the alert log
b) create script for the table
c) the before-insert trigger
d) the xml-schema
e) code for registering the schema
f) the test program
g) platform information

You should report this in a service request on http://metalink.oracle.com.
It is a shame that you put all the effort here to describe your problem, but on the other hand you can now also copy & paste the question to Oracle Support.
Because you are using 10.2.0.3; I am guessing that you have a valid service contract...

Insertion in Table with Virtual Column

Hi,
I am using 11.1.0.7.0 on Solaris 10.
I created following table:
test@mytest> create table mytest (c1 number, c2 number generated always as (1) virtual);
Table created.
test@mytest> create unique index idx on mytest(c2);
Index created.
test@mytest> insert into mytest values(1);
insert into mytest values(1)
ERROR at line 1:
ORA-00947: not enough values
test@mytest> Why it is not letting me insert into the table, because we cannot insert value in a virtual column?
regards

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, ...

How to insert a table with variable rows in smart form

Hi all,
How to insert a table with variable rows in smart form?
Any help would be appreciated.
Regards,
Mahesh.

Hi,
Right click the mouse->create->table
If you want 5 columns, you need to declare 5 cells in one line type of the table
Click on Table -> Details, then do the following
Line Type 1 2 3 4 5
L1 2mm 3mm etc
Here specify the width of the columns as many as you want..
then in the header/main area of the table, click create Table Line, Rowtype is L1, automatically 5 cells will come,In each cell create a text element, display the variable to be printed there.

BI Answers - need 2 compound layouts with tables with different columns

Hi,
I need 2 tables in the same report with different columns displaying. Is this possible?
I wanted to put them in their own compound layout and call each one with a view selector,
but it seems impossible to create a 2nd table with different columns in the one report.
Each time I try and replace one of the columns in the 2nd table with a different column,
a message appears saying the deleted column will be deleted from all views.
Many thanks for anyone's help.
- Jenny

As per my knowledge - your requirement can be done with Pivot view but not with regular table view.
We dont have exclude column - functionality in table view.
Else, instead of creating in same report create the req. with 2 separ. reports but place them on single dashboard in 2 sep. sections.

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.

Table with frozen columns

In a recent project I've had the need of a Java Swing table with frozen columns.
After a long research at the Swing forum at java.sun.org and google I found out that
1. Currently there is no proper Open Source solution
2. All the postings at sun are good concepts, but far away from solutions
3. The only (for me )acceptable commercial solution is the JCTable from Quest (formerly KGroup)
Since I want to have full control over the source code of the table, I decided to collect all the tips from this forums and write my own table.
Here is the my first result:
http://jroller.com/resources/kriede/CoolTable.java
The main idea is to have two tables, one for the locked columns (=fixed columns = frozen columns) and one for the scrollable columns. With all the tips from this forum it was more or less a puzzle to make it work pretty. The next task will be to provide a JTable-like interface, meaning to write delegate/adapter methods to the API of the two nested JTable instances.

The FixedColumnExample from the link that you provided doesn't work with JDK 1.3 or higher.
Anyway, putting a seperate table for the fixed columns into the row header is the first step to solve the problem of fixed columns.
The next problem is to synchonize the scrolling behaviour of the two tables. The FixedColumnExample tries to do it by overwriting the valueChange method (maybe this was working with JDK 1.8), but with JDK 1.2 or higher it is recommended to use ChangeListeners. That's what I am doing, as also described here: http://www.chka.de/swing/components/JScrollPane-bugfix.html.
Another problem is navigation with the tab or arrow keys: The default actions for those events move the selection only within one JTable. It would be nicer, if e.g. the tab key moves the selection within one row across both, the fixed and the scrollable columns.
Those problems and some more are solved in the CoolTable sample:

Export table with LOB column

Hi!
I have to export table with lob column (3 GB is the size of lob segment) and then drop that lob column from table. Table has about 350k rows.
(I was thinking) - I have to:
1. create new tablespace
2. create copy of my table with CTAS in new tablespace
3. alter new table to be NOLOGGING
4. insert all rows from original table with APPEND hint
5. export copy of table using transport tablespace feature
6. drop newly created tablespace
7. drop lob column and rebuild original table
DB is Oracle 9.2.0.6.0.
UNDO tablespace limited on 2GB with retention 10800 secs.
When I tried to insert rows to new table with /*+append*/ hint operation was very very slow so I canceled it.
How much time should I expect for this operation to complete?
Is my UNDO sufficient enough to avoid snapshot too old?
What do you think?
Thanks for your answers!
Regards,
Marko Sutic

I've seen that document before I posted this question.
Still I don't know what should I do. Look at this document - Doc ID: 281461.1
From that document:
FIX
Although the performance of the export cannot be improved directly, possible
alternative solutions are:
+1. If not required, do not use LOB columns.+
or:
+2. Use Transport Tablespace export instead of full/user/table level export.+
or:
+3. Upgrade to Oracle10g and use Export DataPump and Import DataPump.+
I just have to speed up CTAS little more somehow (maybe using parallel processing).
Anyway thanks for suggestion.

Marko

Find size of table with XMLTYPE column STORE AS BINARY XML

Hi,
I have a table with structure as:
CREATE TABLE XML_TABLE_1
ID NUMBER NOT NULL,
SOURCE VARCHAR2(255 CHAR) NOT NULL,
XML_TEXT SYS.XMLTYPE,
CREATION_DATE TIMESTAMP(6) NOT NULL
XMLTYPE XML_TEXT STORE AS BINARY XML (
TABLESPACE Tablespace1_LOB
DISABLE STORAGE IN ROW
CHUNK 16384
RETENTION
CACHE READS
NOLOGGING)
ALLOW NONSCHEMA
DISALLOW ANYSCHEMA
TABLESPACE Tablespace2_DATA
- So HOW do I find the total size occupied by this table. Does BINARY storage work as LOB storage. i.e. I need to consider USER_LOBS as well for this.
OR foll. will work
select segment_name as tablename, sum(bytes/ (1024 * 1024 * 1024 )) as tablesize_in_GB
From dba_segments
where segment_name = 'XML_TABLE_1'
and OWNER = 'SCHEMANAME'
group by segment_name ;
- Also if I am copying it to another table of same structure as:
Insert /*+ append */ into XML_TABLE_2 Select * from XML_TABLE_1.
Then how much space in ROllbackSegment do I need. Is it equal to the size of the table XML_TABLE_1?
Thanks..

I think foll query calculates it right while including the LOB storage as:
SELECT SUM(bytes)/1024/1024/1024 gb
FROM dba_segments
WHERE (owner = 'SCHEMA_NAME' and
segment_name = 'TABLE_NAME')
OR (owner, segment_name) IN (
SELECT owner, segment_name
FROM dba_lobs
WHERE owner = 'SCHEMA_NAME'
AND table_name = 'TABLE_NAME')
It's 80 GB for our Table with XMLType Column.
But for the second point:
Do we need 80GB of UNDO/ROLLBACK Segment for performing:
Insert /*+ append */ into TableName1 Select * from TableName;
Thanks..

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;
Best regards,
Nick

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.

Exporting Table with CLOB Columns

Hello All,
I am trying to export table with clob columns with no luck. It errors saying EXP-00011TABLE do not exist.
I can query the table and the owner is same as what i am exporting it from.
Please let me know.

An 8.0.6 client definitely changes things. Other posters have already posted links to information on what versions of exp and imp can be used to move data between versions.
I will just add that if you were using a client to do the export then if the client version is less than the target database version you can upgrade the client or better yet if possilbe use the target database export utility to perform the export.
I will not criticize the existance of an 8.0.6 system as we had a parent company dump a brand new 8.0.3 application on us less than two years ago. We have since been allowed to update the database and pro*c modules to 9.2.0.6.
If the target database is really 8.0.3 then I suggest you consider using dbms_metadata to generate the DDL, if needed, and SQLPlus to extact the data into delimited files that you can then reload via sqlldr. This would allow you to move the data with some potential adjustments for any 10g only features in the code.

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
