Sequence number adjustment in the column

In my table maintenance generator,
I have one field called sequence number which increments by '1', each time user enters a new record in my table maintenance generator(have coded in such a way).
now the internal table, under sequence column if some records get deleted,
then the numbering of that column should be adjusted automatically.
Like
1st record -     1 A B D
2nd record -     2 A B C
3rd record -     3 A B D
4th record -     4 A B C
5th record -     5 E D F
If some user deletes 3rd record , then instead of showing the TMG as below
1st record -     1 A B D
2nd record -     2 A B C
3th record -     4 A B C
4th record -     5 E D F
the TMG should should show as
(I need that to be sequence column adjusted as )
1st record -     1 A B D
2nd record -     2 A B C
3th record -     3 A B C
4th record -     4 E D F
My thought is to write on new module in PAI,
and buils the logic in case of syst-ucomm = 'DELE'.
Please suggest me any function module availble or any good logic for this
Thanks in ADV.

This really isn't the way the TMG was meant to be used. Normally, one just uses it to manually add change or remove individual records, not a number of records based on some logic. It would probably be simpler to build a simple dynpro to take care of this.

Portal Master-detail form how to auto assign detail record sequence number

Portal Master-detail form how to auto assign detail record sequence number.Please help me?

You can just read the following section
Can I specify a sequence number generator as the default value for a form column?
Yes. Enter the following in the "default value" field for the column:
#<schema name>.<sequence name>.nextval
where <schema name> is the name of the schema containing the sequence, and <sequence name> is the name of the sequence. The entry is preceded by a "#".
For example, if the schema name is "SCOTT", and the sequence name is "CUSTOMER_SEQ", the default value entry is:
#SCOTT.CUSTOMER_SEQ.NEXTVAL
same way you can do for master - detail form.
for more information on forms please refer the following URL.

hope it helps.

Sequence number in ADF FORM.

hi All,
I have a table with ID as primary key and have a sequence created for this primary key and have a trigger for generating sequence number while inserting the record in table.
How can i map this Sequence in ADF so while inserting record from Form i can skip the ID column.
Regards,
Suresh kumar

I am using MySQL and primary key is auto incremented in my table. Therefore I have selected
SQL Plateform : SQL92
Data Type Map : Java
When I am trying to create entiry object, I do not get option of selecting DBSequence. I did some documents reading, I found out that DBSequence is part of "*Java Extended for Oracle*" Data type Map.
While creating the EO , in the Attribute Settings, I click the Browse and search for DBSequence. I found out oracle.jbo.domain.DBSeqence.
Can someone please let me know that I am going to face any problem in future by using DBSequence in his manner?
Thanks in Advance.

XML insertion/updation using merge and generate sequence number

Hi,
I am working on Oracle 11g.
I have a doubt with XML load.
I get an xml and I have to insert or update data into a table A. This I can achieve using MERGE statement.
But there is one column in Table A, that I need to populate with a sequence number, based on the data sent in the xml.
The xml does not send this column data.
And I have to make sure the sequence is created based on the order in which records are present in xml.
For example the MERGE is inserting five rows and then updating next two rows and again inserting 3 rows from xml into table A. The sequence number should be created in the same order for the column in table A.
Also for each new xml, the sequence starts with 1 and ends with the number of records in the xml. So I cannot create a sequence and use seq.nextval.
Please let me know, there is a way of achieveing this.
Thank you!

Hi,
Following up on your previous thread : {thread:id=2403469}
You can use the FOR ORDINALITY clause in XMLTable to generate the required sequence :
MERGE INTO target_table t
USING (
SELECT x.seq_num, x.pk_id, x.col1, x.col2, ...
FROM XMLTable(
         '/root/record'
         passing my_xml_doc
         columns seq_num FOR ORDINALITY
               , pk_id   number       path 'ID'
               , col1    varchar2(30) path 'COL1'
               , col2    varchar2(30) path 'COL2'
       ) x
) src
ON ( t.pk_id = src.pk_id )
WHEN MATCHED THEN UPDATE
SET t.seq_num = src.seq_num
   , t.col1 = src.col1
   , t.col2 = src.col2
WHEN NOT MATCHED THEN INSERT
(seq_num, pk_id, col1, col2, ...)
VALUES (src.seq_num, src.pk_id, src.col1, src.col2, ...)
;

How to create an INSERT trigger which creates a "sequence number"

Imagine a table T_Q with columns C_1, C_2, C_3 and UN_123.
C_1, C_2 and C_3 are all numeric and given by the user.
UN_123 has to be a calculated sequence number starting by 1 and incremented by 1 for each combination of C_1, C_2 and C_3, i.e., the sequence number depends on the key values C_1, C_2 and C_3.
Could anybody provide a code sample on how to create a BEFORE INSERT trigger , which calculates the value of the column UN_123 based on the values of C_1, C_2 and C_3 ??
Premise: Rather than using any sequence, the trigger code should only be based on the table T_Q

I aGenerating a Sequence Number within a String

Hi folks,
I am trying to create a control file which I would be using for load records using SQL*Loader. I need to generate the Sequence Number and use the value for the column REQ_NUM. I have a file TEST.TXT which contains 30 records with STUDENT_ID. I would like to create a control file because I want to load all 30 rows with the same REQ_NUM.
Here is what I have but I need to get the value of the Sequence Number.
spool testing.ctl
'load data infile 'TEST.TXT'
select
'append into table DUMMY_TABLE
FIELDS TERMINATED BY '','' optionally enclosed by ''"''
trailing nullcols
(req_num CONSTANT "select req_num_seq.nextval from dual",
student_id)'
from   dual;
spool off;
exit 0;
{code}
Any help is greatly appreciated. I am on Oracle 9i.

Sorry to have made this complicated but all I want to do is my output of the SQL as something like this.
Now, I have a Sequence out there that I was planning on using. Assuming that the Sequence is currently at 362, so when I run the SQL, I should get this output below. Makes sense ?
append into TEST_TABLE
FIELDS TERMINATED BY ',' optionally enclosed by '"'
trailing nullcols
(req CONSTANT '363',
student_id)
{code}

Sequence number in pre-insert form trigger

i have two tables invoice (master) inv_detail(detail) and assign the invoice number using a sequence number,
by writing the folowing code in the pre-insert trigger
select a.nextval into :inv_no from dual;
( i make the trigger at the form level becuause i have a master (invoice) and detail (inv_detail) relation at the same screen,so i must fetch the value of the
sequence into the :invo_no in the screen,to let the 'copy value from' property at the detail block works so the value of the foreign key will be copied from
the sequence number at the screen.
will this method be a good one for multi user envirment(to select the a.nextval in the pre-insert trigger at the from level?)

Kevin, thank you for the correct explanation. I was making an assumption and of course it was wrong.
Mohannad, please do not try to link the invoice count with the sequence number. Any time you need a count, just do a select count(*). The sequence number is ONLY a unique key, and should represent nothing else.
People have discussed this situation heavily. If you insist on trying to ensure there are no gaps, you will:
1. Fail -- there are many scenarios where gaps will occur.
2. Waste your time.
3. Whatever process you build to try to prevent gaps will cause unnecessary overhead and work for the server, and in a multi-user environment, cause processing bottlenecks due to table locks.

Sequence number/counter in File name using FTP

Hi
I have to add sequence number in the file name. How can i do that? everytime file generates it should pick up the latest file number.
Example File1 File2 File3. 1,2 and 3 are the sequnce number.
Regards

Hi ria,
You can do this by dynamic file creation. Use this following code and cretate an UDF. The map the required file format to the target header structure as below;
UDF
sequence number:
IDENTIFIER is the parameter
Import com.bp.xi.util.*;
Code:
return ServiceUtil.getSequenceValue( IDENTIFIER, container, false );
Dynamic file:
Key & Value is the parameter
Code:
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get( StreamTransformationConstants.DYNAMIC_CONFIGURATION );
DynamicConfigurationKey confkey = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", Key );
conf.put( confkey, Value );
return "";
Input parameter "Key" is given a constant value"FileName"
Second parameter "Value" is the file pattern
Mapping
Constant(File)concat function sequence numberUDF ==> Dynami File udf ==>target header record.
In the receiver communication channel check the adapter specific function, filename
points if useful

Murugavel

Sequence Number By Date Option For File Naming

I would like to see Lightroom have the option to have the sequence numbers be reset when the date changes and increment accordingly. For example, I have the file naming set to use Date (YYYYMMDD) Sequence Number (0001) and the sequence number starting at 1. As Lightroom is now I will end up with 200909010001, 200909010002, 200909020003, 200909020004, 200909030005 200909030006 etc. and what I would like to see is the option for 200909010001, 200909010002, 200909020001, 200909020002, 200909030001 200909030002.
This would make it much faster for renaming or import when using this combination of date and sequence in file names.

Hi
For the Transport Protocol "File Transfer Protocol (FTP)" files are always processed in ascending alphabetical order
If you want the file to be processed in sequence then you can use Quality of Service EOIO in the sender adapter.
The files are processed in the sequence they are picked up.
otherwise use BPM for File Sequencing..
Refer the following Threads

CM25 Sequence Number Maintenance View

Dear guru ,
i enter sequence number operation in the specific view of CM25.
In the sequence number maintenance view the production orders are sorted in order of production order number.
I want that production orders are sorted in this view in order of sequence number operation.
How can i do this ?
Thanks in advance.

I assume that you want to display the sequence number of each order in the mid and lower graphic panel, is that ?? And be able to sort order based in this field ?
Try this
Customizing
Production Planning
Capacity Leveling - Transaction: OPD0 : Overall profile
Go to list Profile: SAPSFCI001
Goto Profile for list variant: SAPSFCD001
Check also the profile for evaluation;
Subprofile for displayed fields: SAPSFCF0
Subprofile for sort criteria: SAPSFCS0
make the required changes, adding Sequence as field
I would suggest to create a complete set of new Z profiles.

Gnerating sequence number in OSB

I have a proxy service which picks up XML messages from a JMS queue. I want to insert a running sequence number in one of the node of the XML. I then want to call a business service which will send the XML out via a webservice.
Is there a option in OSB where I can generate a sequence number or do I have to use the database or is there some option in jms queue. Can the JMS correlation Id be a running sequence number?
Note: The sequence number will have to be unique and should continue the sequence even after server restart.
Appreciate your help on this.
Regards

Please check this post.
Using Weblogic jms message id for unique id
Weblogic's JMS Message ID's are statistically unique and it has a timestamp component included in it... So you can expect an increasing sequence.

Current log sequence number

i have a small doubt :
when there is log switch , the current log sequence number is stored in the control file . Is the same current log sequence number stored in the headers of the datafiles??????
waiting for your answers eargerly.....

nops i don think so.
there is no need for doing this, only controlfile needs to know about the current sequence number

Batch rename without sequence number

In LR3 I originally named imported images with the date, custom
word, and sequence number. I now want to batch rename with just the date, and cust
om word - no sequence number. Yet the rename includes the
numbers anyway, and they are different than the original sequence numbers. How do I get rid of
the unwanted numbers? Thanks

I don't think LR provides a way to cut characters from the end of an existing filename.

Date and Sequence number

I need some help coming up with some SQL that I can put in an Insert Trigger to generate a unique id. The unique ID is composed of the two digit year, the two digit month, and a four digit sequence number. At the beginning of each month, the sequence part of the number should be reset to 0001.
An example of the data follows:
02110001
02110002
02110003
02120001
02120002
02120003
Thanks in advance for any help/advice.

Creating the unique key is relatively straight forward.
CREATE SEQUENCE monthly
START WITH 1 INCREMENT BY 1 NOCACHE;
CREATE TRIGGER my_trigger
BEFORE INSERT ON my_table
FOR EACH ROW
BEGIN
:new.unique_id := TO_CHAR(sysdate,'yymm')||TO_CHAR(monthly.nextval,'fm0000');
END;Depending on your version of Oracle, you may need to select it into a variable from dual before assigning to :new.unique_id. To reset the sequence at the beginning of the month, you could use DBMS_JOB, or cron to run a procedure that drop and re-create the sequence at midnight.
