DB Adapter Multi Table sequence generation through a procedure call

Hi,
I am trying to insert data into multiple tables (master/detail) .The proble I am facing is I need to insert data in such a way that the primary key column should be substitued by the value returned by a procedure/function .
So I cannot use native sequencing as well for the primary key. Do let me know if anyone has done this before or anyone has any suggestions on this
Thanx

here is some sample code for and object type for a simple PO.
create or replace type xxsoa_poline_inbnd_row_type as object

Multi-Value Sequence!

Hello everyone,
First of all, sorry about my poor english! I'm a brazilian undergraduate student but I never attended english classes, kinda auto-learned by attempts... well, I think this is enough to my introduction. Oops, that's something I need to tell also. I'm already kinda experienced with the following databases, but I am very newbie at Oracle. (Firebird[some years and currently using it], DBase[a long long time ago], Paradox[ a long time ago too], MSAccess (omg!!!) and MySQL).
I have the followin' situation:
My very simple test table:
CREATE TABLE TESTSEQ (
SEQNO NUMBER(4),
CLASS VARCHAR2(20),
... constraints, checks, everything else).
Some records:
SeqNo | Class
001 | Red
002 | Red
003 | Red
001 | Green
002 | Green
001 | Blue
002 | Blue
003 | Blue
Ok, let's get into the problem. Each Class must be sequencially numbered. The easiest way is to use "SELECT MAX(SEQNO) WHERE CLASS = Something..", but I will have concurrency problems :)
Usually, the best solution for "autonumbering" is to use a SEQUENCE... then I can look for a SEQCOLORS.NEXTVAL... but I will need to restart it for the Classes.... this way can be a burden.
The "user application" can create a new sequence for each new class... SEQCOLOR_RED, SEQCOLOR_GREEN... and I think this solution is a lot better than mess with the value of a single sequence. (solution 3)
The last solution I though is to use a Single Table SEQCOLORS ( LAST_SEQ, CLASS ), and use a concurrency transaction to "lock" the SEQCOLORS table while get a new value... It's seems to me this is the best. (solution 4)
But, what could be really good and what I'm looking for is a way to create a safe concurrent "multi value sequence". It could be something like:
// CODE
CREATE SEQUENCE MVSEQ_COLORS MULTIVALUE;
MVSEQ_COLORS.ADDINDEX('GREEN');
MVSEQ_COLORS.ADDINDEX('RED');
SELECT MVSEQ_COLORS.NEXTVAL['GREEN'] FROM DUAL.
And know the one million question. Is there any approach for my dream-like sequence above? I'm glad for any tips and if i'm right about the "solution 4", i need some help to the "lock table" thing... the better approach to do it.
Thanks in advance ;)
[]'s
I though that could be good a pratical use:
Relations:
ORDER(_order_id_, description, other_fields...)
ORDER_ITEM(_order_id_, seqno, item_description, other_fields...)
In order_item, seqno must be restart each order... but at my problem I'll add itens to random orders frequently..

Like the answer below, a good and simple approach for real world to the composite primary key is to use a timestamp or a single sequence for everyone, not a multi-sequence. But this is not whats this thread about. The question is not about this particular model, but IF we require a "multi value sequence", what's the best approach. In my particular problem, a timestamp would be a perfect candidate key. (a case where the user or terminal/device is part of the primary key ^^)
"CREATE TABLE TESTSEQ (
DEVICE_ID NUMBER(7),
SEQDATE DATE,
CLASS VARCHAR2(20),
... constraints, checks, everything else)."

If it really needs to be stored, then the question becomes how "current" doees it need to be. If you can take some latency, then you could use an approach similar to what MScallion suggested, and schedule a job in the database to update the sequential serial every x amount of time. Essentially, you would use a real Oracle sequence (or perhaps a timestamp column) to determine the order of the rows to enable you to sort them to assign a serial sequence. you would only need to update rows that currently had no values in the serial key column.
The upside of this is that you do not have the serialization issues you would get from locking based approaches, the downside is that there is a lag between a record being inserted and the key being generated.
If you can go with this approach, then I would. If you need to have child records based on the serial key, then would also recommend that you use a real Oracle sequence as a surrogate key to use in the FK relations with the chilren. That way, you can establish the child relationship immediately if neccessary.
If you cannot take the latency in generating the serial key, then you need to serialize using a "sequence" table, something like:
CREATE TABLE class_seq (
   class_name VARCHAR2(30) NOT NULL,
   last_seq   NUMBER NOT NULL,
   CONSTRAINT class_seq_pk (class_name) PRIMARY KEY)
ORGANIZATION INDEX;I would prime that table with a value of 0 (or the current max sequence in the class) for each class. Then all of your inserts into the table need to be structured like:
SELECT last_seq FROM class_seq
WHERE class_name = <class> FOR UPDATE;
INSERT INTO test_seq (seq, class_name) VALUES (<val from above +1>, <class>);
UPDATE class_seg
SET last_seq = <val inserted>
WHERE class_name = <class>;
COMMIT;I would strongly recommend that if you have to do this, you make really sure that all inserts to this table are done through a stored procedure that encapsulates this logic, and contains enough error checking/handling code to make sure that transactions are commited or rolled back as appropriate.
Having said that, I would also strongly prefer the delayed generation approach, even if you need to schedule the job to run every couple of minutes.
Note that all of the comments above are taking your assertion about the neccessity of this at face value. Personally, I'm not entirely convinced that it is either necessary or desirable, but I haven't read the book :-)

Multi-table mapping is not inserting into the primary table first.

I have an inheritance mapping where the children are mapped to the parent table oids with the "Multi-Table Info" tab.
One of children is not inserting properly. Its insert is attempting to insert into one of the tables from the "Additional Tables" of "Multi-Table Info" instead of the primary table that it is mapped to.
The other children insert correctly. This child is not much different from those.
I looked through the forums, but found nothing similiar.

I would expect the Children to be inserted into both the primary table and the Additional Table? Is the object in question inserted into the primary table at all? Is the problem that it is being inserted into the Additional Table first? If it is, are the primary key names different? Is it a foreign key relationship?
If the object in question has no fields in the additional table is it mapped to the additional table? (it should not be)
Perhaps providing the deployment XML will help determine the problem,

Viewing multi-cam monitor for multi-cam sequences not on track 1

Hi,
I just found out that the multi-cam monitor in the Program Monitor goes blank if the multi-cam sequence is not on track 1. Is there a way to fix this? Thank you in advance.

How do you toggle the track targeting so that you can see the multi-cam preview for two stacked multi-cam sequences? I'd like to cut between different takes and it'd be a pain to toggle every time. Final Cut Pro has no problem of doing this but it seems that Premiere is a little picky about track targeting. I attached an example of how the project would look like going through two takes of multi-cam sequences.

Help with multi-table mapping for one-to-many object inheritance

Hi,
I have posted on here before regarding this (Toplink mapping for one-to-many object inheritance but I am still having problems mapping my object model to my schema.
Object model
The Person and Organisation objects contain base information and have the primary keys person_id and organisation_id. It is important that there is no duplication of person and organisation records, no matter how many times they are saved in different roles.
There are two types of licenceholder in the problem domain, and the ILicenceHolder interface defines information and methods that are common to both. The PersonalLicenceHolder object represents one of these types of licenceholder, and is always a person, so this class extends Person and implements ILicenceHolder.
The additional information and methods that are required by the second type of licenceholder are defined in the interface IPremisesLicenceHolder, which extends ILicenceHolder. Premises licence holders can either be people or organisations, so I have two objects to represent these - PremisesLicenceHolderPerson which implements IPremisesLicenceHolder and extends Person, and PremisesLicenceHolderOrganisation which implements IPremisesLicenceHolder and extends Organisation.
The model is further complicated by the fact that any single Person may be both a PersonalLicenceHolder and a PremisesLicenceHolderPerson, and may be so several times over. In this case, the same basic Person information needs to be linked to several different sets of licenceholder information. In the same way, any single Organisation may be a PremisesLicenceHolderOrganisation several times over.
Sorry this is complicated!
Schema
I have Person and Organisation tables containing the basic information with the primary keys person_id and organisation_id.
I have tried to follow Donald Smith's advice and have created a Role table to record the specialised information for the different types of licence holder. I want the foreign keys in this table to be licenceholder_id and licence_id. Licenceholder_id will reference either organisation_id or person_id, and licence_id will reference the primary key of the Licence table to link the licenceholder to the licence. Because I am struggling with the mapping, I have changed licenceholder_id to person_id in an attempt to get it working with the Person object before I try the Organisation.
Then, when a new licenceholder is added, if the person/organisation is already in the database, a new record is created in the Role table linking the existing person/organisation to the existing licence rather than duplicating the person/organisation information.
Mapping
I am trying to use the toplink mapping workbench to map my PremisesLicenceHolderPerson object to my schema. I have mapped all inherited attributes to superclass (Person). The primary table that the attributes are mapped to is Person, and I have used the multi-table info tab to add Roles as an additional table and map the remaining attributes to that.
I have created the references PERSON_ROLES which maps person.person_id to roles.person_id, ROLES_PERSON which maps roles.person_id to person.person_id and ROLES_LICENCE which maps roles.licence_id to licence.licence_id.
I think I have put in all the relationships, but I cannot get rid of the error message "The following primary key fields are unmapped: PERSON_ID".
Please can somebody tell me how to map this properly?
Thank you.

I'm not positive about your mappings, but it looks like the Person object should really have a 1:M or M:M mapping to the Licenceholder table. This then means that your object model should be similar, in that Person object could have many Licenses, instead of being LicenceHolders. From the looks of it, you have it set up from the LicenceHolder perspective. What could be done instead if a LicenceHolder could have a 1:1 reference to a person data object, rather than actually be a Person. This would allow the person data to be easily shared among licences.
LicenceHolder1 has an entry in the LicenceHolder table and Person table. LicenceHolder2 also has entries in these tables, but uses the same entry in the Person table- essentially it is the same person/person_ID. If both are new objects, TopLink would try to insert the same person object into the Person table twice. I'm not sure how you have gotten around or are planning to get around this problem.
Since you are using inheritance, it means that LicenceHolder needs a writable mapping to the person.person_id field- most commonly done through a direct to field mapping. From the description, it looks like roles.person_id is a foreign key in the multiple table mapping, meaning it would be set based on the value in the person.person_id field, but the person.person_id isn't actually mapped in the object. Check to make sure that the ID attribute LicenceHolder is inheriting from person hasn't been remapped in the LicenceHolder descriptor to a different field.
Best Regards,
Chris

Splitter operator doesnt use multi table inserts in OWB...very very urgent

Hi,
I am using OWB 9i to carry out tranformations. I want to copy the same seuence numbers to the two target tables.
Scenario:
I have a source table source_table, which is connected to a splitter and the splitter is used to dump the records in two target tables namely target1_table and target2_table. I have a sequence which is also an input to the splitter, so that I can have the same sequence number in the the two output groups of he splitter. I then map the sequence number from the two output groups to the two target tables expecting to have the same sequence number in the target tables. But when I see the generated code it creates two procedures and effectively inserts sequencing numbers in the target tables which are not consistent. Please help me so that I have the same sequencing numbers in the target tables which are consistent.
Well the above example works in row based operating mode but not in set based mode. Please give me a valid explanation.
OWB pdf says that splitter uses multi table inserts for multiple targets. After seeing the generated code for set based operations I dont agree to this.
Its very urgent.
thanks a lot in advance.

Hi Mark,
You got me wrong, let me explain you the problem again.
RDBMS oracle 9.2.0.4
OWB 9.2.0.2.8
I have three tables T1,T2 and T3.
T1 is the source table and the remaining two tables T2 and T3 are target tables.
Following are the contents of table T1 -
SQl>select * from T1;
DEPTNAME LOCATIO?N
COMP PUNE
MECH BOMBAY
ELEC A.P
Now I want to populate the two destination tables T2 and T3 with the records in T1.
For this I am using splitter operator in OWB which is suppose to generate multi table inserts, but unfortunately its not doing so when I generate the SQL. There si no "insert all" command in the sql it generates.
What I want is, when I populate T2 and T3 I use a sequence generator and I want the same sequences for T2 and T3 eg.
SQl>select * from T2;
NEXT_VAL DEPTNAME LOCATIO?N
1 COMP PUNE
2 MECH BOMBAY
3 ELEC A.P
SQl>select * from T3;
NEXT_VAL DEPTNAME LOCATIO?N
1 COMP PUNE
2 MECH BOMBAY
3 ELEC A.P
I am able to achieve this when I set the operating mode to ROW BASED. I am not geting the same result when I set the operating mode to SET BASED.
Help me....

Multi Camera sequence went black (mostly)

So, I edited three separate multi camera sequences... They all looked great and I exported them through media encoder. When I went to look at my files one of the three had a really small file size and I noticed it was all black.
I went back into premeir pro cc and sure enough that multi cam seqence was all black as well (except about 3 seconds of footage right in the middle from two different cameras). Now when I go back to the original sequence (not the nested multi cam) It is just fine so I know the clips are still linked into PP. Also, I can make a new multi cam sequence from the original and it is just fine as well.
I think PP just F'd up... and unless someone can tell me how to go back in the file save history or something I'm sunk because premier auto saved when I last closed it. I'm seriously at a loss as to why this happened as it was just fine when I went to export it... or at least nearly immediately before. Why is there 3 seconds of footage in the middle of all black 47min sequence? and that 3 seconds is from inside of a 10 minute clip on the original un nested sequence so It's not as if just one video file was showing up.
Okay, so more than figuring out what happened I want to move on with my life. Is there anyway to copy the edit points onto a brand new multi cam sequence? Does anyone have any ideas what happened that I can undo?
Thanks,
Okay, so this is weird.... so, the original un nested sequence was 1:30 hours with 45 minutes of unused audio at the beginning. When I made my nested sequence for multi cam editing I selected the last 45 minutes and nested that. Everything functioned just fine, but somehow during export it took my multi cam sequence and added back in the 45 minutes of blank audio....so when I extended the multi cam sequence to 1:30 there was all my video... but my edits were all done on top of the audio. Seriously Stupid, and definitely a bug!!!
Is there any sort of file save history that I can revert to?

I accidentally found the auto-save folder which had 50+ versions of my project saved (thanks to no one, including Mark for pointing out that Premier Pro made new files each time it auto saved) And the issue is present in all of them, even back to a time when I am 100% positive I was working on the sequence inside of premier and it was displaying correctly.
So, that means that premier was not saving my file correctly, even though it was displaying correctly inside the program at that time. Then, when media encoder opened it for export the nested sequence was out of sync from the original, and today when I reopened it in premier it showed everything out of sync.
I'm using premier CC as a trial because I was considering upgrading from cs5 for the clip sync and increased features. Clip sync didn't work for my files so I had to use pluraleyes anyways and this bug I experienced today means that I lost 4hrs of work and 2 more hrs trying to figure out if I could recover my 4hrs of lost work. Now, I have to re-edit and I'll definitely be doing it in CS5

Multi table insert and ....tricky problem

I have three account related table
--staging table where all raw records exist
acc_event_stage
(acc_id NUMBER(22) NOT NULL,
event_code varchar2(50) NOT NULL,
event_date date not null);
--production table where valid record are moved from staging table
acc_event
(acc_id NUMBER(22) NOT NULL,
event_code varchar2(50) NOT NULL,
event_date date not null);
--error records from staging are moved in here
err_file
(acc_id NUMBER(22) NOT NULL,
error_code varchar2(50) NOT NULL);
--summary records from production account table
acc_event_summary
(acc_id NUMBER(22) NOT NULL,
event_date date NOT NULL,
instance_flag char(1) not null);
records in the staging table may look like this(I have put it in simple english for ease)
open account A on June 12 8 am
close account A on June 12 9 am
open account A on June 12 11 am
Rules
Account cannot be closed if an open account doesnt exist
account cannot be updated if an open account doesnt exist
account cannot be opened if an open account already exist.
Since I am using
Insert all
when open account record and account already exist
into ...error table
when close account record and open account doesnt exist
into ...error table
else
into account_event table.
select * from acc_event_stage order by ..
wondering if the staging table has records like this
open account A on June 12 8 am
close account A on June 12 9 am
open account A on June 12 11 am
then how can I validate some of the records given the rule above.I can do the validation from existing records (before the staging table data arrived) without any problem.But the tricky part is the new records in the staging table.
This can be easily achieved if I do cursor loop method,but doing a multi table insert looks like a problem
any opinion.?
thx
m

In short,in simple example,
through multi table insert if I insert record in production account event table from
staging account event table,making sure that the record doesnt exist in the production table.This will bomb if 2 open account exist in the current staging table.
It will also bomb if an open account and then close account exist.
etc.

Shared-table-sequence in atg

HI guys,
What is shared-table-sequence attribute for table tab why we should use and when
I have gone through the document but i didnot get exactly
Please any one please give me clear picture on this

Hi,
Like Nitin Dubey said it's used in many to many relationship.
Typically used only in versioned repositories, this attribute is set to an integer between 1-9, which specifies the relationship of this table to other tables in a many-to-many relationship.
In a two-sided many-to-many relationship, the table with the ‘second’ side should set this attribute to 2; the table with the ‘first’ side should set this attribute to 1.
In a versioned repository, set this attribute to 1 for the table that contains the asset_version column; set it to 2 for the table that contains the sec_asset_version table.
For more information look this doc: Oracle ATG Web Commerce - <table>

Exported Videos from Multi-Camera Sequence not Identical to the Frame

I imported media and made a multi-camera sequence, set the in/out points, exported each camera with identical in/out points. However, the exported durations differ by a few frames even though I'm conforming to ProRes with same in/out points. Anyone know why they are not accurate to the frame? This worked out fine in FCP7.

I'm a little lost. Take me through the process step by step (with reasoning behind).

Can we change table into XML through OWB

Hi everyone,
Is it possible to change table into XML through OWB?
Can anybody help me.
just send me the steps to do
Thanks in advance
Rachit

Hello, Rachit
As far as I understand our question you need to export data from the table into XML file.
I dont think you have direct operator within OWB (at least for ver. 9.2.0.4). But anyway, you could write PLSQL procedure using DBMS_XMLQUERY to perform XML generation and transform it with your stylesheet.
Unfortunately, this package uses DOM to work with XML, so could have a serious memory consumption while trying to export large tables this way.

Multi-Cam Sequence - Effects on Source Sequence Don't Apply

Project has multi-cam sequence (nested), with color correction and other effects applied to the source sequence. However, effects on the source sequence don't apply as they would with a normal nested sequence. I'm assuming there is a setting that I'm unaware of that would enable this functionality, but so far I've been unable to find it.
Any help would be greatly appreciated!

It really was not necessary for me to determine that the effects were not properly applied, but since you asked, yes I did the blur test. I also have no idea why it does not work.
I have 4 hours of multicam footage and a client deadline fast approaching, and am feeling EXTREMELY frustrated that Adobe doesn't seem to have a proper help line phone number or chat through which I can promptly receive proper help after I have committed to this program for the next year of my professional life.

Single image sequence generation. ?

Hello, ..
Essentially, I'm looking to find the best solution, to the idea of building sequences where and with using - importing, different sequencial, single images.
— To be clearer perhaps, I'm a Weather student / enthusiast, and this would be toward generating a sequence / different sequences .. of hourly weather-satellite obtained images.
To this point, or up until very recently, and in fact for several years previous, I have - in fact, been able to do this fairly simply, with using an older version of QuickTime (older logo, I think that main version offered still, through "Tiger".) and, with once I've dropped a first or more initial image more in particular, into the application, then merely dragging and dropping whichever others into its main viewer-window, checking save, and naming the file.
— Perhaps, unorthodox. But, it's worked just fine for the idea.
— And, of course, this idea can't be used with the newer version/s of QuickTime.
"very recently": .... Today, and with having been using this method of "simple sequence" generation, together with older version of QuickTime, on my relatively new "iMac", and running Snow Leopard, Mac OS X v. 10.6.8 - all up to date, ....
.. I've found that I'm no longer able to access the older version of the application. (I think this advent, might be related to a "MacKeeper" clean-up that I did recently. ....)
— In fact, the main reason that I can't say more exactly, which version it is - or was, in fact.
Beyond this question more general, I'm thinking — (Something, I think that I'd read at one point in the past.) — that I can in fact do what I've suggested above, with / within QuickTime Pro.
Hope this is clear - at all.
Any help. ?
Appreciate your response and time.

Opening an "image sequence" (folder of sequentially named same dimension files) is a feature found only in QuickTime Player Pro.
Beginning with Snow Leopard the OS includes QuickTime Player X (in Lion it is 10.1) in the Applications folder and QuickTime 7.6.6 is moved to the Utilities folder.
QuickTime X has its own feature set but can't be upgraded to "Pro".

Sequence generation(urgent)

Hi
im new to jdev..I would like to set sequence generation for table fields.Im using JSp as my client and populating fields in the jsp screen.pls let me know is there any thing to set on wizard or any help in tutorial..thnks..

I'm assuming that you've added your code segment to EmpImpl.java.
The first parameter to SequenceImpl() should be the name of a database sequence, not the name of a table column.
Once you've changed that, if you still get the same error, you need to check whether EmpImpl.java has a method called setId(), since this is what your error is complaining about. Your entity should contain accessor (getter and setter) methods by default. If your entity doesn't have these methods, then edit the entity, select the Java tab in the Entity Object Wizard, and check "accessor methods" for the entity object class.
Lastly, I recommend testing your business components in the business component browser (aka the tester). This is a way of making sure your business logic works before you try to run your client.

How to stabilize parts of a multi-cam sequence ?

I want to stabilize parts of a multi-cam-sequence. So I right-klick the clip to send it to Aftereffects. But this will end up in sending the whole multi-clip (two povs, 30 minutes of length).
How can I extract parts of the multi-cam-sequence I want to have stabilized?

Have you cut the clip each side before sending it?
You could try making a subclip..... though I haven't tried it so I don't know for sure that would work - it's worth trying through.
An alternative is to render the part of the clip to a file, stabilize that then use the replace footage to replace the footage on the multicam sequence. This is more hassle, but at least you have an actual file that is stable rather than relying on dymanic linking (which has failed me a couple of times).
