How fast is it possible to learn Oracle if I'm proficient in mySQL?

Hi ladies and gents,
I am planning on creating an estate agency website. I have about 3 months to do that. I did computer science in uni, so i know java, c++, SQL, x/html, html, a bit of javascript, css. I bought a PHP and Oracle book.
My question is, considering the fact that I have never created a website with a fully functional database on, how long does it normally take for experience people to create such a site?
If I am a fast learner would I be able to do it in 3 months? I am really scared that I am taking on a challenge that I will not be able to handle. I will be fully committed and obviously will be spending day and night on designing and coding the site.
Finally the most important question I want people to answer is this, if I am already proficient in SQL, will learning Oracle take much time? Can I not do the site with SQL instead of Oracle at the moment?
Massive "Thanks" to any who answers my questions. I am mainly interested in your views so any reply will be welcome.

I've no idea on the project, having never done anything like that myself, but a working knowledge of SQL, whilst handy, isn't the be all and end all of working with a database.
Firstly, you've got to get the design of the database right - normalised tables, primary keys, foreign keys, etc. Getting that right makes the rest of your job much easier!
Secondly, a lot depends on the database you're working with. You'd take a different approach SQL / code wise when using Access than you would when using Oracle. So, you'd have to get familiar with the capabilities of your particular database platform in order to be able to make the best use out of it. (For example, Oracle has a different method of ensuring read consistency than MS SQL Server does, and what you can do in one big SQL statement in Oracle, you would break up into smaller queries and use temporary tables to hold the data.)
Thirdly, the SQL used in each database platform is slightly different - most of it is standard, but there are bolt-ons which are not the same across the databases (eg. in the case of Oracle, how you handle DATEs is not the same as how you'd do it in SQL Server, Sybase, etc.)
If I were you, I'd stick to using something that I knew, rather than trying to learn everything in 3 months! However, if you were wanting to bolt a website onto an Oracle database, I believe APEX could well suit your needs.

How fast text search field in Oracle without using Intermedia?

How fast text search field in Oracle without using Intermedia? Thank you, Paul.

yes,it is overriden in VOImpl
public void executeQuery()
        setQuery((new StringBuilder()).append(selectStmt).append(" order by ").append(getOrderByClause()).toString());
        OAApplicationModuleImpl oaapplicationmoduleimpl = (OAApplicationModuleImpl)getApplicationModule();
        OAApplicationModuleImpl _tmp = oaapplicationmoduleimpl;
        if(oaapplicationmoduleimpl.isLoggingEnabled(1))
            OAApplicationModuleImpl _tmp1 = oaapplicationmoduleimpl;
            oaapplicationmoduleimpl.writeDiagnostics((new StringBuilder()).append(getClass().getName()).append(".executeQuery").toString(), (new StringBuilder()).append(" Query:").append(getQuery()).toString(), 1);
        super.executeQuery();
But I have extended VO and substituted the VO . In the substituted VOImpl, instead of executeQuery(),I have written
public void customExecuteQuery()
          setQuery((new StringBuilder()).append(selectStmt).append(" order by ").append(getOrderByClause()).toString());
          executeQuery();
Will this work,or do I need to do any changes?
Thanks,

You may not agree with it, but it doesn't mean you have to be abusive.Well if you feel your point is valid and you're not just trolling, then please provide evidence or justification to back up your claims.
If I were you I wouldn't bother learning Oracle - it's just a constant life of bug-fixingBugs can exist in any development environment. It isn't specific to Oracle, Microsoft or any other company.
Bugs in the product are typically fixed with regular patches and most companies make those readily available, so there's no issue there.
Bugs in the software developed with the product are the responsibility of the developer and are not an issue with the product itself. Good design, understanding and testing make for good application development. The product on assists to facilitate the development, not to ensure that there aren't idiots developing using it.
and trying to get assistance from Oracle Support.What's the problem getting assistance from Oracle Support? Can't say I've ever had any real problems with them. They've always been most amenable. From what I gather, most people have issues with support when they themselves don't provide the necessary information to detail the issue in the first place.
There are too many people learning Oracle these days (because it's pretty easy), and most jobs are getting out-sourced anyway.There are too many people getting certification and calling themselves Oracle developers/dba's and they don't have relevant experience, that's true, but that doesn't just relate to Oracle, it relates to many areas of IT (and I'm sure many other businesses too).
Oracle is as easy as the depth you get into it. The deeper you go the more complex it can be. It's good that it's easy to get into as nobody want to come into learning a product that is just overly complex, but it's also good that it offers the power, flexibility and complexity when it is necessary.
As for many jobs getting out-sourced, I guess that depends on your country and the economic climate and the nature of your business. I think there's a little less out sourcing going on lately as companies are beginning to realise that outsourcing their development often leaves them with unmaintainable, bug ridden code, written by people who don't care about the bussiness, but just care about getting money in their pockets. Of course there are still companies where the management just see a cheap short term option and go for it anyway, which is sad really.
Saying all that however, you're points are certainly no reason to not bother learning Oracle. Your points could be applied to any product on the market. Hence why they came across as trolling.

There are links to sample code and viewlets - the vewlets are a good place to start.
There are loads of white papers.

Can any one tell me how to download The Demo Version of Oracle JD Edwards Enterprise One 9.0, for Practice purpose,

and how much capacity of hard disk need to store the same.
I am Learning the Oracle JD Edwards ERP, so that i want to Practice it in my home.
Is it possible to work demo version with out Internet facilities?

Thanks for the link, but not able to find JDE demo version for download.It's not quite as simple as 'click the download' button. You gotta get the infrastructure in place.
As recommended, go to http://edelivery.oracle.com , click on Continue, fill the legal page, select JD Edwards for your OS, and start downloading. I would probably start and stop with the Installation document, since that likely has information such 'how much of the 60GB download is really required'.
In the Oracle world, learning and practicing starts with reading.

How to use JavaMail 1.4 with Oracle Application Server 10g (9.0.4.0.0)

Hi all,
I'd like to know if it's possible and how to use JavaMail 1.4 with Oracle Application Server 10g (9.0.4.0.0), Windows version.
With the following code, I can see that the mail.jar used by the server is the one included in the jdk installation :
// I'm testing InternetAddress.class because I want to use commons-email-1.2.jar that requires mail.jar 1.4 (or higher) and activation.jar 1.1 (or higher)
// and I know that inside the commons-email-1.2.jar file, I need to call the InternetAddress.validate() method that throws a java.lang.NoSuchMethodError: javax.mail.internet.InternetAddress.validate()V if it is used with mail.jar 1.2.
Class cls = javax.mail.internet.InternetAddress.class;
java.security.ProtectionDomain pDomain = cls.getProtectionDomain();
java.security.CodeSource cSource = pDomain.getCodeSource();
java.net.URL location = cSource.getLocation();
System.out.println(location.toString());
This code returns : file:/C:/oracle/app/jdk/jre/lib/ext/mail.jar and this mail.jar file has an implementation version number: 1.2
- I've tried to include my own mail.jar (1.4.2) and activation.jar (1.1.1) files in the war file that I deploy, but it doesn't work (the server still uses the same mail.jar 1.2)
- I've tried to put the mail.jar (1.4.2) and activation.jar (1.1.1) files in the applib directory of my OC4J instance, but it doesn't work (the server still uses the same mail.jar 1.2)
- I know that a patch exists : I've read the following document: How to Make Libraries such as mail.jar and activation.jar Swappable ? [ID 552432.1]
This article talks about the Patch 6514136, but this patch only applies to : Oracle Containers for J2EE - Version: 10.1.3.3.0
Can you please help me ?
Thanks in advance for your answers,
Laurent

I strongly suggest to upgrade to AS 10.1.3 to get this.
Think of future support of AS 9.0.4. You will get not critical patch updates anymore.

Installation Guides should be clear enough, if read. Also read Release Notes for additional support/unsupport info.

However the Installation Guide for Database Client adds:

How to rename the column name in oracle 8i?

hi,
Does anyone know how to rename the column name in oracle 8i?My method was drop the relationship key first then delete the old column,finally add the new column.
Thanks for your replay.
jing

There is no facilty to rename a column name in Oracle 8i. This is possible from Oracle 9.2 version onwards.
For you task one example given below.
Example:-
Already existed table is ITEMS
columns in ITEMS are ITID, ITEMNAME.
But instead of ITID I want ITEMID.
Solution:-
step 1 :- create table items_dup
as select itid itemid, itemname from items;
step 2 :- drop table items;
step 3 :- rename items_dup to items;
Result:-
ITEMS table contains columns ITEMID, ITEMNAME

Need Best way to start learning Oracle 11g DBA

Hi.This is Tejaswi.
I want to learn Oracle 11g DBA.I've downloaded all software's and Documentation for Orcl 11g R2. Now. i want to start Learning DBA. Can any one suggest me the best way to Start learning DBA?
Please suggest me the good books For Oracle Architecture and SQL.......

Hello Tejaswi,
The advice you got about reading the Oracle Concepts and 2 Day DBA documentation is very good advice.
I found that knowing some SQL*Plus and SQL Developer was also very helpful as, they both provide a way to interface with the database and try the things you read about. For SQL Plus, I used the book:
Oracle SQL*Plus: The Definitive Guide, 2nd Edition
By Jonathan Gennick
Publisher : O'Reilly
ISBN : 0-596-00746-9 I openly recommend it. It is easy to read, the book is very well thought out, it covers what you really need to know (and more too). The author explains the subjects very well. I would definitely learn some SQL Plus and SQL developer before getting into the 2 Day DBA document (make those 2 days about 7 days each if not more).
To learn SQL, I "sort of" used (I say "sort of" because I only read some parts of it available online and at the local bookstore):
Oracle SQL by Example
By Alice Rischert
Publisher: Prentice Hallit probably has more SQL than you'd need as a DBA but, it is an excellent book you may want to consider.
If you are starting from scratch, as I did, you'll find that you need to learn multiple things at the same time. I believe SQL Plus is the best place to start, along with possibly the Concepts document. That will give you a base to build upon.
HTH,
John.

Suggested books/video series for learning oracle sql?

What are some good books/ videos for a beginner to learn oracle sql?
I learn best by being able to go through exercises.
I am using Oracle 11g express edition and sql developer. In sql developer I have only one connection to the HR schema.
Also, can I connect to the SCOTT schema in oracle 11g?

Hi,
The SQL Language reference is a great book, but its a bit dry for a beginner.
How about starting with the Getting Started and 2 Day guides here
http://docs.oracle.com/cd/E17781_01/index.htm
There are a lot of tutorials here as well
https://apex.oracle.com/pls/apex/f?p=44785:1:0::NO
google will also bring up lots of hits as well
