Change partitioned column range in range partioning in 11g

Hi All,
First of all , i am thankful to all of you for your help and suggestions in past. I have one new issue. I am using Oracle 11. There is one new functionality in 11g to do range paritioning while table creation and do daily partitioning.
CREATE TABLE TEST(
DUE_DAY DATE,
ID VARCHAR2(10 BYTE),
NAME VARCHAR2(25 BYTE)
PARTITION BY RANGE (DUE_DAY)
INTERVAL( NUMTODSINTERVAL(1,'DAY'))
PARTITION FIRST VALUES LESS THAN (TO_DATE('2012-02-05 12:00:00', 'SYYYY-MM-DD HH24:MI:SS')));
Now I found i create the partition range wrong so each partition has data from previous day 12:00 afternoon to today 12:00 afternoon instead of daily data from 00:00 am to 11:59 pm because i mentioned wrong range in partition.
I supposed to do like this:
CREATE TABLE TEST(
DUE_DAY DATE,
ID VARCHAR2(10 BYTE),
NAME VARCHAR2(25 BYTE)
PARTITION BY RANGE (DUE_DAY)
INTERVAL( NUMTODSINTERVAL(1,'DAY'))
PARTITION FIRST VALUES LESS THAN (TO_DATE('2012-02-05 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')));
My question is: Is there any way i can change it now as table already has huge data in it, so i cant go with creation of another partitioned table with correct partition range? Please let me know your suggestions and comments to resolve this issue.
Regards
Dev

I don't think it is possible to achieve this without creating a new/an intermediate table.
If you can afford down-time, you should create new table, load data into it (in parallel with nologging), drop original table and rename new table.
If you want this switchover as online operation, you can use DBMS_REDEFINITION as follows:

Change partition by range column

Hi,
is it possible (oracel 11g) to change partition by range column for a table without recreating the whole table ?
now i have it : partition by range (COLUMN_A)
i need it : partition by range (COLUMN_B)
Thanks

Yes

How to change the year in a range of column dates to the new year?

Depends on the pattern of the dates. The last procedure will work for any pattern, or no pattern at all.
For examples.the dates are assumed to be in column A, starting at A2
Sequential dates?
Enter first updated date in the first cell.
Enter =A2+1 in cell A3. Copy the cell.
Select A3 to the end of the list. Paste.
With the cells still selected, Copy, then go Edit > Paste Values.
Evenly spaced dates?
Same procedure as above, but replace +1 in the formula with + and the number of days between dates in the list.
Randomly spaced dates?
Select cell B2. Press option-left arrow to insert a (temporary) column to the left of column B.
Click on the empty cell B2 in the new column. Enter the formula below:
=DATE(YEAR(A)+1,MONTH(A),DAY(A))
Copy the cell, then select B2 - Bn where n is the last ow containing a date to be converted. Paste,
With the cells still selected, Copy.
Click on A2, then go Edit > Paste values.
Click on the column B reference tab to select all of column B.
Hover the mouse over the right end of the reference tab, and click the black triangle when it appears.
Choose Delete Column from the menu that appears.

You got local index and 3 non-partitioned "NORMAL" b-tree tyep indexes
Also if we create index as :(create index i_name on t_name(c_name)) By default it will create Global index. Please correct me......
Above staement will create non-partitioned index
Here is an example of creating global partitioned indexes
CREATE INDEX month_ix ON sales(sales_month)
   GLOBAL PARTITION BY RANGE(sales_month)
      (PARTITION pm1_ix VALUES LESS THAN (2)
       PARTITION pm2_ix VALUES LESS THAN (3)
       PARTITION pm3_ix VALUES LESS THAN (4)
        PARTITION pm12_ix VALUES LESS THAN (MAXVALUE));Regards

Adding a partition by giving date range

Hi
I have a table with partition by range over date in julian format. I want to add a new partition for date range 01-jan-2007 to 15-Feb-2007. There are partitions for last date of January and Feburary.
Can I add a new partition as
alter table <table_name> add partition <partition_name>
values less than <date_in_julian> and greater than <date_in_julian>

I don't believe that is valid syntax for range partitioning.
The "greater than" piece is taken care of by the "values less than" definition of the partition prior to the one being added.
If I understand your question, you have a partition with a date range ending prior to '01-feb-2007' and another partition with a date range ending prior to '01-mar-2007' and you would like to add a partition to cover the date range of 01-jan-2007 through 15-feb-2007? If so that is not possible and would be a different table all together. If you need to adjust the date ranges of current partitions, you could split the february partition, then merge the january partition with the newly split first 1/2 of february. Or if you need a mechanism to focus in on that date range, perhaps a materialized view of the target table specifying that date range.

STEP 3
I need to get all the dispatches on 1st of August and hence issue the statement as follows:
select * from test_partition where TRUNC(CREATE_DT)='01-Aug-2008' and EMP_RGN_NM = 'SE'
Using a function over the partitioned column, will it avaoid partition pruning? I mean will it scan all the partitiones instead of going to specific partition?
I need this urgently since we are having a discussion on this in few minutes from now.
Thanks so much
Saff

What about a function based index ?

Best way to change partition key on existing table

Hi,
Using Oracle 11.20.3 on AIX.
We have a table about 800 million rows and 120gb in size.
Want to try copies oif this table to evalaute different partitiong strategies.
What is the quickest way to do this?
Would have liked say datapump table 1 tro disk and datapumo import the data to new table but do the tables need to be of the same format.
Thanks

First your subject asks a different question that the text you posted: Best way to change partition key on existing table. The answer to that question is YOU CAN'T. All data has to be moved to change the partition key since each partition/subpartition is in its own segment. You either create a new table or use DBMS_REDEFINITION to redefine the table online.
Why do you want to export all data to a file first? That just adds to the time and cost of doing the op.
What problem are you trying to use partitioning to solve? Performance? Data maintenance? For performance the appropriate partitioning key and whether to use subpartitions depends on the types of queries and the query predicates you typically use as well as the columns that may be suitable for partition keys.
For maintenance a common method is to partition on a date by year/month/day so you can more easily load new daily/weekly/monthly data into its own partition or drop old data that no longer needs to be kept online.
You should use a small subset of the data when testing your partitionings strategies.
Can you do the partitioning offline in an outage window? If not then using the DBMS_REDEFINITION is your only option.
Without knowing what you are trying to accomplish only general advice can be given. You even mentioned that you might want to use a different set of columns than the curren table has.
A standard heap table uses ONE segment for its data (ignoring possible LOB segments). A partitioned/subpartitioned table uses ONE segment for each partition/subpartition. This means that ALL data must be moved to partition the table (unless you are only creating one partition).
This means that every partitioning scheme that uses a different partition key requires ALL data to be moved again for that test.
Provide some information about what problem you are trying to solve.
>
Is this quicker than datapump?
>
Yes - exporting the data simplying moves it all an additional time. Ok to export if you need a backup before you start.
>
Found artcle which talks about using merge option on datapump import to convert partitioned table to non-partitioned table.
>
How would that apply to you? That isn't what you said you wanted to do.

Change partitioning attribute

Hi,
I have a big table partitioned by a date column (one partition for each month). I need to change the partitioning column to another date column (partitions would also be one per month). Does any one know a simple way to do that?
Database version is 11gR2.
Thanks!

You would almost certainly need to recreate the table and move all the data from the old table to the new table. You can combine or split partitions with DDL but you can't fundamentally change how partitioning is done.

Change download columns from report

Hi! I have a report, with some columns and I'd like to change the columns when downloading as csv file.
Let's say that I have a report with col1,col2, col3,col4 and some hidden columns: col5, col6, col7. When I download the file I'd like to have only
col2, col3, col6, col7.
How can I do this?
Thanks!

Currently there is no way to do this. The CSV export function just re-runs the exact same report as you see it on the screen and transforms it to CSV format.
Another option is to create a report with the columns you want in the CSV on another page, and use the export:CSV template as in
http://tinypic.com/jzya2t.jpg
and provide a link to that page. This will run that page and instead of showing the page it will popup the File download box.
Hope this helps.

How to change the column value which is coming from DO by a calculated field?

Hi all,
I want to change a column value based on my calculated field value. I have a column which is coming from DO which is based on External Data Source. I have a calculated field in my report. When there is any change in the calculated field then the column which is coming from DO needs to be changed. It means the DO needs to get updated when there is a change in the calculated field. Or like if the calculated field meets some condition then I need to change/update the same in the DO. This has to be done on the fly. the report should not submitted for this. when there is a change in the calculated column the DO column needs to get updated.
Thanks,
Venky.

How can i change the column label text in a alv table display

how can i change the column label text in a alv table display??
A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
* declare column, settings, header object
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
get column by specifying column name.
lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
set Header Text as null
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( ' ' ).
My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."
i have checked in debugging and the error occured at the statement :
lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
Thanks,

I found it myself how to do it. The error says that it is not able to find the reference object i.e it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...
DATA : lr_cmp_usage TYPE REF TO if_wd_component_usage,
 lr_if_controller TYPE REF TO iwci_salv_wd_table,
 lr_cmdl TYPE REF TO cl_salv_wd_config_table,
 lr_col TYPE REF TO cl_salv_wd_column.
DATA : node_year TYPE REF TO if_wd_context_node,
 elem_year TYPE REF TO if_wd_context_element,
 stru_year TYPE if_alv_layout=>element_importing,
 item_year LIKE stru_year-i_current_year,
 lf_string TYPE char(x),
DATA: lr_column TYPE REF TO cl_salv_wd_column.

Get the entered value from the input field of the screen
node_year = wd_context->get_child_node( name = 'IMPORTING_NODE' ).
elem_year = node_year->get_element( ).
elem_year->get_attribute(
 EXPORTING
 name = 'IMPORT_NODE-PARAMETER'
 IMPORTING
 value = L_IMPORT_PARAM ).
WRITE L_IMPORT_PARAM TO lf_string.
Get the reference of the table
lr_cmp_usage = wd_this->wd_cpuse_alv( ).
IF lr_cmp_usage->has_active_component( ) IS INITIAL.
 lr_cmp_usage->create_component( ).
ENDIF.
lr_if_controller = wd_this->wd_cpifc_alv( ).
lr_column_settings = lr_if_controller->get_model( ).
get column by specifying column name.
IF lr_column_settings IS BOUND.
 lr_column = lr_column_settings->get_column( 'COLUMN_NAME').
set Header Text as null
 lr_column_header = lr_column->get_header( ).
 lr_column_header->set_text( lf_string ).
endif.

How can I change excel column header using Labile.

As I said in my previous post, column headers in Excel are merely row 1 cells. May be I missing something here, so please be more explicit with your question.
I guess you are using the Excel Report tools, and you want to modify an existing sheet. From my limited experience with the Excel Report tools, it is not possible to open an existing woorkbook (except as template...), so the answer to your question should be "Forget it"...
The work around is to use the example I pointed for you before, and either to write the whole new colum headers as a string array, starting in A1, or to write a single string to a given cell in row 1.
Hope this helps

Change the column width on the fly

Dear all,
I have a problem, i have a matrix report, the row is "the project name" and the column is "the items" using within each project, and the problem is the items are variable from time to time the report run for each project, so its exceeds the paper width.
And the question is, is there any way to change the width of the column on the fly, i mean dynamiclly change the column width each time the report is called to make all items fit the paper width.
Thank u

i don't think that we can change the layout of the column in reports
The simple solution for that problem is that u have to
fix the horizontal and vertical layout of the text item
better is to post this problem at reports forum
