Can i create a sequence using java?

Hi,
I have a problem here.
I have to update records to my oracle9i database.
One of the fields in my tables has to be auto number, meaning whenever i add records to this table, this fields will automatically be updated jus like a counter.
I am told that i could do this by writing a sequence. can any1 help me out?
Thanks a million!

To create a sequence in Oracle you can use this (with SCHEMA being replaced by whatever Schema that you are adding the Sequence to)...
CREATE SEQUENCE SCHEMA.SEQUENCEGENERATOR
START WITH 1 INCREMENT BY 1 MINVALUE 1 CACHE 20 NOCYCLE NOORDER ;
From a stored procedure or java code you could
then use the following to get the next available number
SELECT SEQUENCEGENERATOR.nextval INTO v_record_id from dual;
This may or may not work for your needs. Everytime the Select statement is executed a number will be "used". As an alternative you could use something like .... Select Max(number) from Table (this could be table that contains your "auto number" or a seperate support table.

Can I create Oracle Database using Java ???

HI ...
Can I create a Database using Java... ? If yes can any one tell me how ? I mean provide some codeing help... ???

If you mean a table yes, since the create table statement is exactly that, an SQL statement, if you mean an SID then I would have to say (AFAIK) no.

Can not create i.war using java -jar ords.war static

C:\glassfish4\ords>java -jar ords.war static "c:\app\sybrandb\apex_4.2.6\apex\im
ages"
WAR Generation complete
WAR location : C:\glassfish4\ords\i.war
Context path : /i
Static resources : c:\app\sybrandb\apex_4.2.6\apex\images
Ensure the static resources are available at path: c:\app\sybrandb\apex_4.2.6\ap

I downloaded ORDS from OTN yesterday
Needless to say this directory does exist (it works when I run the listener standalone, providing this path)
Why is everything which Oracle releases in this area always broken and badly documented?
HELP!

To create the manifest, you use the constructor
JarOutputStream(OutputStream out, Manifest man).
However, I am having problems with creation of my files and I came here to look for answers. No .war file i have created has been deployable.

Can't create a sequence within a pl/sql block with execute immediate.

Hi All. I created a user and granted it the 'create sequence' privilege though a role. In a pl/sql block I try to create a sequence using 'execute immediate' but get a 1031-insufficient privileges error. If I grant create sequence directly to the user, the pl/sql block completes successfully. Can anyone explain this behavior? We're running 11.2 Enterprise Editon.
Thanks,
Mark

In a definer's rights stored procedure (the default), you only have access to privileges that have been granted directly, not via a role.
There are two basic reasons for that. First, roles can be enabled or disabled, default and non-default, password-protected, etc. so the set of roles a particular user actually has is session-specific. Oracle needs to know at compile time what privileges the owner of the procedure has. The only way to do that (without deferring the privilege check) is to ignore privileges granted through roles.
Second, since 99% of privilege management DBAs do involves granting and revoking roles, it's helpful that changing role privileges will never cause objects to be marked invalid and recompiled which can have side-effects on applications. DBAs only need to worry about causing problems on those rare cases where they are granting or revoking direct privileges to users.
You can create an invoker's rights stored procedure by adding the clause (AUTHID CURRENT_USER). That defer's the security check to run-time but allows the procedure to see privileges granted through roles in the current session. But that means that the caller of the procedure would need to have the CREATE SEQUENCE privilege through the role, not the owner of the procedure.
And just to make the point, dynamic object creation in PL/SQL is almost always a red flag that there is something problematic in your design. If you are creating sequences dynamically, that means that you'd have to refer to them dynamically throughout your code which means that your inserts would need to use dynamic SQL. That's not a particularly easy or safe way to develop code.

You are essentially asking how to write an IDE (Integrated Development Environment). This is a big question. You might start by looking at existing IDE's (JBuilder, Forte...) and see how they do it. If you want source, there is probably an open source IDE you can lift most of your code from.

How to create sql database using java frame or appelet?

thanks a lot

While duffymo is correct in regard to most major database products, it's my understanding (warning! wild-ass guess coming) that the Hypersonic DB is more "application-centric" and the dynamic creation of databases is part of its design. It's pure Java database software, and therefore is not appropriate for all database projects, in particular those that require extremely high-performance.
See http://hsqldb.org/
I've not used it yet (but soon though), and I can't really advise anyone about it.
However, I'm wondering if you phrased you question in a way that is confusing us. To most of us in casual conversation, a "database" is both (1) a large organized collection of data and (2) the software that is used to organize and access it. However, the phrase "create a database" usually means creating a (1) database (a collection of data) using an already created (2) database software, such as Oracle, MySQL, DB2, HSQDB, etc., etc. If you'r question is, how do a create some new database software using Java, the answer is that this is a very very big and hard thing to do for the general case and probably not something you want to be doing.

check out javadoc for java.io
File reldir=new File("NewDir");//relatively where your program runs
reldir.mkdir();
File absdir=new File("C:/NewDir");//absolute path
reldir.mkdir();
File newdir=new File(absdir,"SubDir");//defines another dir under absdir
newdir.mkdir();

HT5071 Can I create a book using the IBooks Author word processing software, save it as a PDF, then have it professionally printed by an offset press to sale in brick and mortar stores? If so, is this procedure free me from any IBooks restrictions?

Can I create a book using the IBooks Author word processing software, save it as a PDF, then have it professionally printed on an offset press to sale in brick and mortar stores? If so, is this procedure free from any IBooks restrictions?

It's your content, under your control.
If you output as an .ibooks file, and you want to sell it, the store is the only outlet, otherwise, you can do as you wish.

How do I increase the maximum number of images I can acquire in a sequence using the IMAQ 1424 with 80 MB of onboard memory and a Duncan Tech camera?

I've increased the maximum number of buffers to higher than I need, but I still cannot acquire more than 139 images with the Duncan Tech digital video camera before I get a memory lock error. Is there any way to increase the number of images I can acquire in a sequence using the IMAQ 1424 with 80MB of onboard memory?

It sounds like you are already bypassing the onboard memory. If you weren't, you would only be able to acquire about 20 images.
If I understand correctly, you do not convert the images until after you acquire them. This means each acquired image is 4.13 MB, and 139 images will take 574 MB of memory. I wouldn't be surprised if that was all the free memory available on a 1 GB machine. The operating system, LabVIEW and any other software running probably take up the rest of the memory. You might want to put your computer on a diet and minimize the number of other programs and utilities running. The only other option I see is getting more memory if possible.
Is there a way that you can reduce the number of images you need to acquire? Pe
rhaps skipping every other frame? Do you really need more than 139 images?
Is it possible to acquire the images in monochrome? That would triple the number of images that you could acquire.

Can't Create New Sequence

FCS2 Upgraded and updated yesterday.
For some reason starting today I can't create new sequences. New Sequence doesn't make a new sequence in any of the bins (but doesn't crash - just nothing happens), whether from the File menu or right-clicking in a bin.
Importing XML (from Color or even via Color > Send to FCP) doesn't create a sequence either.
Creating a new project gives me an empty project, with no sequences in it either.
Anyone?

And, as always, FCP Rescue can make backing up or trashing your preferences nice and easy.

Once you've got a functioning preference set, you can back it up to restore later in case this happens again.
