Learning PL/SQL in Oracle 10G XE

Successfully installed Oracle 10G XE on my desktop. I'm a newbie Oracle user who wants to learn PL/SQL through Oracle 10G XE.
Is this possible? Hope you can give me tips and advice on how I would start with this?
Thanks!

Certainly possible. I would suggest you crack open the PL/SQL Users Guide. DO you have previous programming experience? If so, looks at the examples.

Calling java from pl/sql in oracle 10g?its very urgent.

Hi Friends,
i hve simple java code:
class Hell
public static String Hello()
return"hello world";
& compile this code using javac & loaded Hell.class in to database using this command
c:\>loadjava -user chandru/shekar@pulser c:\Hell.class
& i wrote pl/sql like:
CREATE OR REPLACE FUNCTION Hell RETURN String as language java name 'Hell.Hello() return java.lang.String';
i will compile the code & run but at that time this error i am getting:
ORA-29516: Aurora assertion failure: Assertion failure at eox.c:317
Uncaught exception System error: java/lang/UnsupportedClassVersionError
I am using oracle 10g.Plzzzzzzzzz help me.Its very important to for me.
Is any path i hve to set for oracle 10g database.Plz any one help me.

shekar

Hello here is how I solved the problem
Let us assume that i try to load the file Hello.Java into the user scott.
public class Hello {
     public static String world() {
          return "hello world";
1) Dropjava
You must drop the java class if you already have loaded the class onto the server.
dropjava -u scott/tiger Hello.class
2) load class on server and let the server compile the source code.
It is necessary to compile the source code on the server when the server and the local machine have different Java versions. To check which Java version there is running on the client machine open a command prompt and write Java -version
loadjava -user scott/tiger -resolve Hello.java
3) Publish stored procedure
sqlplus scott/tiger@oracle
CREATE OR REPLACE FUNCTION helloworld RETURN VARCHAR2 AS                LANGUAGE JAVA NAME 'Hello.world () return java.lang.String';
4)Call stored procedure
VARIABLE myString VARCHAR2(20);
CALL helloworld() INTO :myString;
PRINT myString;

SQL Query (Oracle 10g)

Hi All,
Please find the following requirement.
Requirement -
There are 2 standalone database named database A and
database B used by 2 separate application. Database A
has schema S1 and Database B has schema S2.
Schema S1 has around 40 master tables which get updated
very frequently. This 40 tables are also present in S2
also.
We want the both the 40 tables to be in sync every
hourly or half any hour.
eg. If records are added/updated deleted in S1.emp then
same should be done in S2.emp and visa versa also.
We dont want to use dblink,materialised views or
scripts. Is there any feature in Oracle 10G like
replication or Streams where in this can be done.
Incase if are not able to replicate both ways then at
least one way can we replicate ? like any records are
added/updated deleted in S1.emp then same should be done
in S2.emp and similarly in the other 39 tables.
Thank you

Can anyone provide a SQl query to create a
schema/user named 'test' with username as 'system'
and password as 'manager'system user is created during database creation, it's internal Oracle admin user that shouldn't be used as schema holder.
In Oracle database, Oracle user is schema holder there's no seperate schema name to be defined other than username.

I've come across this tool from Oracle for Migrating SQL and mySQL databases to Oracle 10g. But the procedure and documentation was not clear. I wanted to try this once and hence I am posting here.
Could you please share your experiences if you have also tried this one already? All your inputs will be of great help in helping me understand this tool and its usage.
Thank you.

How to restore some *.sql in oracle 10g

Hi someone gave me a cd with .sql backup and told me to restore it in oracle.
Can someone tell me how to do it or some hints in the type of recovery I should use?
Thanks

mmm. not much detail in there. The .sql files are probably sqlplus scripts that at a guess create objects. If you're lucky they will also define the schema that they should be created in. The .zip file is probably a file of data either in some predefined format e.g. csv, in which case you can load it using sqlldr or it could be a big file of insert statements.
My first steps would be -
1/ find out which user the scripts are supposed to be run as.
2/ read the .sql scripts to find out what they do and which order they should be run in
3/ run the .sql scripts
4/ look at the zipped file and work out how to load it.

SQL Loader Oracle 10g problem in upload date with time data -- Very urgent.

Hi
I am trying to upload data using SQL loader. There are three columns in the table
defined as DATE. When I tried upload a data like this '2007-02-15 15:10:20', it is not loading time part. The date stored as 02/15/2008' only. There is not time on that. I tried with many different format nothing work. Can please help me ?
I have also tried with to_date --> to_timestamp it did not work.
The application is going to be in production, I cannot change DATE to TIME STAMP. This is very urgent.
LASTWRITTEN "decode(:LASTWRITTEN,'null',Null, to_date(:LASTWRITTEN,'YYYY-MM-DD HH24:Mi:SS'))",
CREATEDON "decode(:CREATEDON,'null',Null, to_date(:CREATEDON,'YYYY-MM-DD HH24:Mi:SS'))",
LASTUPDATEDON(21) "decode(:LASTUPDATEDON,'null',Null, to_date(:LASTUPDATEDON(21),'DD/MM/YYYY HH24:MI:SS'))"

Your problem is most likely in decode - the return type in your expression will be character based on first search value ('null'), so it will be implicitly converted to character and then again implicitly converted to date by loading into date column. At some of this conversions you probably are loosing your time part. You can try instead use cast:
SQL> desc t
Name                                      Null?    Type

Recommened book for learning PL/SQL

I've been trying to learn PL/SQL from Oracle's documentation, and I'm a bit tired of it.
All the information is there, but you really need to scan back and forth to collect all the bits you need. It is rather difficult.
Can you recommend a good book? I want to learn all the idea and concepts, not just the syntax. So please don't direct me to "Learn PL/SQL in 21 days".
Thanks.

It may be true that one can get away with documentation. However, it greatly depends on your background. If you learn language X, and this is your very first exposure to programming, you won't find documentation inspirational. You will suffer with badly chosen textbook too. As you progress, the matter of a good book becomes less and less important. You may find that for learning your second language you don't need a book, and this is especially true in the era of internet, when there is a great competition among web tutorials.
My apology for not being specific, but the matter of finding a good book is easy -- you just go to amazon, find several with high ASR, and chose the one based upon readers reviews. You will unlikely to expect better feedback to your question here.

Returning Partial Resultsets - Oracle 10g

Hi,
Is there a way that i can issue a long-running SQL against Oracle 10g & attempt to cancel my query half-way through, but still be able to "get hold" of the "partial result set" queried till that point in time ?
Thanks in advance.

you can run query and cancel it as well.
what do mean by partitial result set?

tnx,I haven't a clue.
As you have been advised in many of your posts, go study the documentation for whichever specific topic you are interested in.
For me to answer your questions, I would need to go get that documentation.
Then I would need to read that documentation.
Then I would need to write a forum post that interprets what I think I learned from that documentation.
It is so very much faster if YOU go do that instead of posting to a forum and expecting others to do it. You will remember what you study for a lot longer time if you teach yourself.

Oracle 10g - Introduction to SQL course question

Two years ago I completed the Oracle 9i - Introduction to SQL course. An complete the #1Z0-007 exam and pass with almost 100%.
I notice that Oracle 10g - Introduction to SQL courses are now being offer. If I have already done the Oracle 9i course and have been using SQL for the pass two years. Is doing the Oracle 10g - Introduction to SQL worthwhile ?
Will I learn anything new or is the course almost the same ?
Thanks
Brendon

Brendon,
Almost certainly not useful. I'd compare the contents of the course you did with the features that have been introduced into Oracle since the version that the course was based on, and try to find some material on these features.
Cheerio,
Colin

How do you compare Oracle 10G with SQL Server 2005?

exept for performance and pricing...
We haven't decide to upgrade SQL Server 2000 to SQL Server 2005 or buy more license for Oracle 10G...
Any comments are welcome!

OK I only came here because of APC's referral down the piece (I was curious where all the hits came from - cheers Andrew). Comments embedded anyway
Thanks Gaff!
* Staff Experience with product - how flexible is
your staff?
--Staff need to learn sth. new...:)That's a fair motivation if recruitment and retention of staff is an issue - if you want reliability giving business systems to people who don't know the tech is a rather foolish move.
* Current product use Corporation/group - if you have
15 SQL Server boxes and no Oracle, what is the
impetus for change? Same if you have 15 Oracle boxes
and no SQL Server ones.
--80% SQL server and 20% Oracle. We are thinking to
balance to 50%-50%.I'm curious as to the reasoning behind this? I don't really see what the benefit is.
* Features - Do you want/need text handling
capabilities? Data mining? Storage of non-text
records? XML?
--I think both of DB system can do these.They can
* Scalability - Is one Windows box going to meet your
needs or do you need to scale (now or eventually) to
multiple boxes of multiple CPUs?
--This is really a benefit feature of Oracle better
than SQL Server.SQLServer scales - it just scales in a different way (federated databases vs RAC).
Thank u for ur US$.02Are you evaluating the platform for an in-house development or a database neutral application - if the latter I'd be sorely tempted to find out what the development platform is or read the docs for clues. For example we are looking at a product that supports SQLServer,MSDE and Oracle. In the FAQ "how do I choose between SQLServer and MSDE?", if we do implement it will be on an MS platform.
I consider this probably the most crucial factor since SQLServer and Oracle have different architectural features they tend to generate different development approaches - porting one to the other nearly always hurts the new platform. Plus if I need support I'd be hoping that I got a bug fix from a developer and not from a developer whose fix was then ported.
The same applies to in-house dev obviously, but there at least you can hire people with the right skillset for the app development.
