Split Oracle 11g Table Partition and Insert new rows
Hi,
I have a doubt that i would like to be clarified. I need to split a partition of a table with more than 800 Million records, but at the same time (during the split operation) i need to insert new records (not in the partition that is being splited). Is there any problem/risk doing this? Is the insert ETL process going to fail ?
Thanks in advance
Greetings.
Nuno

Hi Enrique,
Thanks for posting in MSDN.
Based on the description, you want to modify the formula for the A1 and B1 cell when you insert a new rows.
Yes, we can use Worksheet.Change to dermin the change of data on the worksheet then we can modify the formula as we wanted. Here is a sample for your reference:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Me.Range("A1").Formula = "=MAX($A2:$A" & Me.UsedRange.Rows.Count & ")"
Me.Range("B1").Formula = "=MIN($B2:$B" & Me.UsedRange.Rows.Count & ")"
End Sub

Min and Max and insert new rows
Hello,
I am really a beginner in Excel (2007). I am not sure if this is the correct forum, anyway.
I have grouped some rows in a sheet (rows 1, 2 and 3, columns A and B, table below), some of the columns have numeric values in that group and I have a row (inside that group) that shows the maximum and minimum values (row 1):
A B
+ 1 43 12 <- MAX and MIN values for row 2 and 3 columns A and B
+ 2 34 12
+ 3 43 34
I am using MAX and MIN functions: A1 = MAX($A2:$A$3), B1 = MIN($B$2:$B$3)
The problem comes when I want to insert more rows after row 3, the formula keeps wrapping to A$2:$A$3 therefore I need to readjust the formula to: MAX($A2:$A$4) manually (for MIN is the same).
A B
+ 1 43 12 <- Are the same, they should be
"98 and 10"
+ 2 34 12
+ 3 43 34
+ 4 98 10 <- New row, but the maximum and minimum continues to be the same, I want to extend the formula automatically to the 4 row when I insert the new row.
Question:
How can I extend the function of the MAX and MIN formula automatically when I insert new rows?
Please consider that I may insert rows at the beginning, in the middle or the end.
Thanks,
Enrique.

Removing rows and inserting new rows with new data in JTAble!!! (Plz. help)
I have a problem, The scenario is that when I click any folder that si in my JTable's first row, the table is update by removing all the rows and showing only the contents of my selected folder. Right now it's not removing the rows and instead throwing exceptions. The code is attached. The methods to look are upDateTabel(...) and clearTableData(....), after clearing all my rows then I proceed on adding my data to the Jtable and inserting rows but it's not being done. May be I have a problem in my DefaultTableModel class. Please see the code below what I am doing wrong and how should I do it. Any help is appreciated.
Thanks

#####################################The following code works fine but it doesn't show me the new updated date in my JTable. I tried to print the values that I am getting and it does give the values on the prompt but doesn't show me on the JTable only first two are shown and the rest of the table is filled with the same values. I don't know what's going on and am tired of this TableModel thing so pla. take a time to give me some suggestions. Thanks

How to split the blob byte array and insert in oracle
how to split the blob byte array and insert in oracle
I am having a string which is of more than lenght 4000 so i am using BLOB datatype as input to get the string.
need to split the blob in oracle and store in the different column
The string is of bytearray i need to strore it in each column based on the byte array.this will be my input i need to split the above and store it in different columns in a table.
for spliting say
Column1 -1 byte
Column2-3 byte
Column3-5 byte
ColumnN-5 byte
Table will have corresponding data type
Column1 - number(10,2)
Column2 - Float
Column3 - Float
ColumnN-Float
here Column2 datatype is float but it will always have 3 byte information.
where as Column3 datatype is also float but it will always have 5 byte information.
Say N is Column 120 -
Receiver JDBC: Error while doing the Deleting and Inserting new records
Hi All,
I am doing Idoc to JDBC scenario. In this I am collecting & bundling different type of Idocs and then sending to the JDBC receiver. My requirement is to delete the existing records in the database and insert the new records. I have configures as mentioned in the link
Re: Combining DELETE and INSERT statements in JDBC receiver
In the above link its shows for single mapping. In my scenario I am using multi mapping for collecting idocs in BPM. If I configured for normal mapping then it is working fine(Deleting existing records and Inserting new record). Whenever I am using multi mapping then I am getting following error in the receiver JDBC communication channel u201CError while parsing or executing XML-SQL document: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)u201D . Can you please tell me what might be the problem.
Thanks & Regards,
T.PurushothamHi !
check this out:
JDBC - No 'action' attribute found in XML document - error
JDBC receiver adapter: No 'action' attribute found in XML document
It appears that the inbound payload (the one that is going from XI to the JDBC adapter) does not have the requiered tag to specify which SQL action to execute in the receiver system. Maybe the multimapping is not creating the desired output message format.

BOM Change - Delete an item(s) and insert new line items
Hi,
We need to mass update BOMs like for some of the existing BOM's we need to delete some line items and insert new line items. We want to use the BOMMAT04 IDOC in LSMW but I'd like to know couple of things before I go ahead with that approach
For instance, I've a finished good material 12345678 and it has three components
a) Item 0010 Material 30101010 of quantity 10
b) Item 0020 Material 30101011 of quantity 11
C) Item 0030 Material 30101012 of quantity 12
Now, I'd like delete Item 0010 and add a new item 0040 Material 30101013 of quantity 13.
In the segment E1STKOM, there is LOEKZ (Deletion Flag) but I dont want to flag for deletion but instead delete the whole line item and add a new line item.
Is there any way to achieve this using BOMMAT04 IDOC? If not, can you please suggest me a better way to do it
Any help is greatly appreciated
Thanks,
SrinivasDear Srinivas,
1.IF you want to change for an individual BOM,use CS02,select the item which you want to delete,select the entire and click on
delete button and then add new line items and save.
2.For Mass changes of BOM you can use CS20.
3.Check these functional module's also if you want to change using a report,
CS_BI_BOM_CHANGE_BATCH_INPUT Change bill of material via batch input
CSEP_MAT_BOM_SELECT_CHANGE API Bills of Material: Select BOM(s)
CS_CL_P_BOM_MASS_CHANGE
CS_CL_S_BOM_CHANGE_COMPLETE
Check and revert back,.

Very Common Scenario - Insert new Rows whose primary Key is not in View Obj
Question : How can you add new records when the primary key of the records are not present in view ? I am facing infinite loop for the below logic .
The View Object is derived from 2 entity object (tableA,tableB) . The view has created in such a way that tableA data is updatable and tableB is read only. The view contains all the unique records of tableA and tableB . i,e the SQL query returns all the existing records from tableA , and those are not in tableA picks from tableB . Therefore , the Sql Query returns the primary key of tableA as 0 for the records which are not present in tableA but exist in tableB .
there fore My sql qery like below
select A.P_ID, A.mapping_id, A.dataValue FROM tableA A
UNION select 0 P_ID , B.mapping_id , 0 dataValue From tableB B ;
Now my challenge is how can to add those new records that taken from table B and insert to TableA ? I am getting an infinite loop for the below logic -
Below code has been written in my Managed bean -
public void addNewSelectedMappings(){
DCBindingContainer dcb = (DCBindingContainer)evaluateEL("#{bindings}");
DCIteratorBinding dciter =
dcb.findIteratorBinding("CustomView1Iterator");
ViewObject vo = dciter.getViewObject();
Row row = null;
while ((row = vo.getCurrentRow()) != null)
Number mappingId =
(oracle.jbo.domain.Number)row.getAttribute("mappingId");
java.lang.Number dataValue = ( java.lang.Number)row.getAttribute("dataValue ");
if(mappingId .equals(0)){
BindingContext bindingContext = BindingContext.getCurrent();
BindingContainer bindings = bindingContext.getCurrentBindingsEntry();
// call the client interface defined in the AM
OperationBinding methodWithArgs = (OperationBinding) bindings.get("insertNewRow");
//add argument
methodWithArgs.getParamsMap().put("mappingId",mappingId);

The base idea here is if the record is added successfully you would then get the new primary key then manually add the record to the underlying data source. Does not matter if we are talking a single table or a master-detail setup.
The following shows the basics
https://code.msdn.microsoft.com/Adding-new-records-into-bff5eaaf
All of the above is done without using a DataSet yet the same thing needs to happen with a DataSet, simply focus on the one table.

ODI - SCD Type 2 - Insert new row error
Hi All,
For Dimension I have a surrogate key, a natural key, and a column with "overwrite on change", start_date, end_date, current_record_ind. When I run the interface with the default SCD Type 2 for SQl server, this runs fine. But when I change that one column from "overwrite on change" to "insert new row", it fails on the update step. What should I be looking for anf fixing.
Thanks for your time and help.DB: SQL Server 2008.
IKM = IKM MSSQL Slowly Changing Dimension
Error Message: ODI-1228 - Incorrect syntax near the keyword from.
Code: update T
set
from database.dbo.Dim_type as T,
database.dbo.I$_Dim_type as S
where T.Cd = S.Cd
and T.Current_rec_ind = 1
and IND_UPDATE = 'U'
To overcome the issue, I have commented the update code in the Knowledge module and the insert works, but for this one it is ok, but I have requirements where one column needs to be overwritten and other column changes will require to add a new record. How to handle both?
Thanks for your time. -
How to lock a table when i insert a row
hi, friends,
how to lock a table when i insert a row, then unlock the tableIf you want to lock the whole table so that no-one else can do DML then you go LOCK TABLE <table> IN EXCLUSIVE MODE. This lock remains in force until you commit or rollback.
There are less powerful locking modes available, but you can look those up in the OTN online documentation.

Could some please help me in the setps involved in it .
Thanks a Lot in advanceIf you can use Data Pump, here are your commands:

Table Partitions and Rolling Window: free space not reclaimed
I have a couple of processes that involve the rolling window scenario where we drop an old partition and add a new partition monthly. We are seeing, however, that free space is not being reclaimed, and so I keep having to feed new datafiles into the tablespace (which is LMT). I was (mistakenly, it seems) under the impression that dropping a partition frees up that space for re-use.
We're currently on Oracle 10gR2 (10.2.0.2), but these tablespaces were orginally created in 9i. I've read that one solution is to implement "table shrinking," however I also see that is only available on tables in an ASSM tablespace. I see that ASSM is the default for tablespaces in 10gR2, but since my tablespaces were created in 9i, I assume they are not ASSM.
I'd like to see what other people think of this scenario. Surely a lot of people do the rolling window scenario and need space reclaimed.No, it is of concern because Sanadra was messing with the partitions. She could have inadvertantly caused something to happen, in this case the free-space issue, and it's imperative to get all of the details.

Insert new row into oracle databse through application module usng ADF Form
I am using Jdeveloper 11.1.2. I am a beginner. I had tried in-built createInsert and commit method to add new row into oracle DB. For that, I had created ViewObject, VOImpl and AMImpl. Then, I created to jsf page. On first page, I dragged and dropped createInsert fn and VO(as ADF-readonly table) from DC Palette. and on second page, I dragged and dropped my VO(as ADF-Form) and commit (as Button) from DC palette. I created task-flow for it. when i click on createInsert button, i redirected to second page. where i filled all the required information on form. After filling, when i clicked commit button, i redirected to first page.(coz i created task flow to return first page after commit). New row is inserted into ADF-table, but when i checked my oracle DB, there was nothing added.
Thus, I want to use custom method to insert row into OracleDB. So how can i get this? what are the steps required to do this? what programming codes required in Bean.java and AMImpl.java. Or is there any other steps to do this?
please provide me detail steps and programming code for bean, amimpl or for VOImpl or EOImpl.
please help me.User,
To insert a row into the db you have to use a VO which is based on an EO (entity object). There is no java class (or impl) needed. You can all do this decoratively.
All you have to think of is the PK of the new row. You can use Groovy for that (http://tompeez.wordpress.com/2011/09/02/using-groovy-expression-to-set-a-primary-key-with-a-sequence-number/)
The rest is like you described it yourself. Drag the Vo onto the page, drop it as read only table, drag the createInsert onto the page as button and set up the navigation. On the second page drag the same VO onto the page and drop it as ADF Form. drag the commit operation onto the page as button and setup the navigation back to the first page.
