I have a new project working with an existing oracle database. I've always been a SQLServer guy, so first time with Oracle.
Any recommendations for a SQLServer Management Studio type app for Oracle?
I would start with Oracle SQL Developer. It's a client app so you can see your tables, run queries, etc. It's free, fast and will get you started.
(It's not as good as toad, of course)
toad
You can also use pl/sql developer: http://www.allroundautomations.com/plsqldev.html?gclid=CJLCqNrIz5kCFYQ-3godM3Pmug
I personally like Toad the best but I know many people who prefer SQL Developer. Definite pros and cons to both but like a lot of things it comes down to what you are used to. I haven't used the freeware version of Toad much but I've heard it's somewhat lacking. In my opinion, if you have money to spend go with Toad, if you are looking for something for free go with SQL Developer.

When I was a student we studied Oracle Database 10g: SQL and PL/SQL textbooks. At that time I asked the lecturer if I can take lab files. And he told me that they are freely available at Oracle website. But now I can't find them. I mean a filled database. At that time it contained data about King, Kochar, De Haan etc and about their departments.
Any Oracle version would suit. 10g would be fine. And newer filed would be ok as well.
Thank you in advance.
you can install the sample schemas when you initially create the database or you can install them afterwards if the database already exists.
First you can try looking in $ORACLE_HOME/demo/schema/. The sample schema install scripts should be in there.
If you need to download them from Oracle, head to their website under the Downloads section for Oracle Database, and select the version and platform you are using currently. The example schemas are in the Oracle Database Examples zip file.
There should be similar instructions for each version, but the link to 11g is below.
Oracle® Database Sample Schemas 11g Release 2 (11.2)

I'm having a little hard time using the SQL Developer, like when doing lengthy scripts and there's an error somewhere, I have to go at most line by line searching the error. I recently shifted from Toad since it is not a free software anymore. Do we have have any open sourced free alternative to SQL Developer?
All of these tools rely on Oracle for information on the location of an error. If you don't get that information in SQL Developer then you're not going to get it from another.
Well, if you only need a software that will check your query for errors, and that the error will be pointed out by line, personally I'm using this site. I have been using it to check the errors line by line.

I'm looking for an Oracle database management tool like sql server management studio.
I've searched the internet and found a lot of tools on the following link:
http://www.freedownloadscenter.com/Search/oracle.html.
But I don't know which one is better.
I need a stable and easy-to-use GUI tool for working on windows.
The best free ones are (in no particular order)
SQL Developer
TOra
TOAD
Oracle Enterprise Manager (parts are included in the licence)
Eclipse plugin - SQL Explorer
The best commercial ones are (in no particular order)
TOAD
DBArtisan
Oracle Enterprise Manager
PL/SQL Developer
My shop uses an open-source Eclipse plugin called SQL Explorer: http://eclipsesql.sourceforge.net/ It has good stuff for examining schemata; it integrates with your source code control system; it works on other database table servers too.
We also use a commercial tool called PL/SQL Developer: http://www.allroundautomations.com/plsqldev.html
This tool has a "SQL Beautifier" which can tidy up some of the hairiest queries you can imagine. In tidying them up, it helps the one writing the query find typos. It also has a context menu that will do "EXPLAIN PLAN" on a query that's already running, and a way to stop a running query. Those are incredibly handy tools.
Carpenteri mentioned Oracle Enterprise Manager. That comes with your Oracle thick client. I find it helpful for getting an instance-wide view of what's going on in your server.
If you are looking for a system management tool for your Oracle database it is worth looking at the Oracle Enterprise Manager
You could use a combination of some tools like SQL Developer, SQLTools and Aqua Data Studio

I am a 3 year experienced software developer with fairly good TSQL knowledge in SQL Server. I am looking for expanding skill to Oracle also. What all things I should learn to say confidently thaty 'I know Oracle'?
Any free online certification available?
Pease share your thoughts..
Thanks
Lijo
Assuming you want to expand your Oracle application development skills (and not your DBA skills) you could look at gaining the 1Z0-047 Oracle Database SQL Expert certification. A good study guide for this is OCA Oracle Database SQL Expert Exam Guide: Exam 1Z0-047. I used this in combination with the Oracle 11g SQL Reference to pass 1Z0-047.
Working with Oracle in production for a couple of years will also help you to expand your Oracle skills.
As an introduction to essential Oracle concepts and techniques have a look at Expert Oracle Database Architecture: 9i and 10g Programming Techniques and Solutions by Tom Kyte.
As to "free online certifications", I'd not bother with those (if any).
They have no value, are impossible to verify that the person claiming to hold them actually does and are not recognised by pretty much anyone.
At best they could serve as practice for the real exams, at worst they'll give you a bad impression about your skills (as they may well have bad questions requiring factually incorrect answers).

I currently work with an Oracle database and we use stored procedures for all our SQL queries. The problem I have is that we do not really having a coding standard for our packages. So what happens is that every developer has a different style (or in some cases no sense of style) in how they format there packages. Making them difficult to read and work on with out first reformatting. We all pretty much just use Notepad or Notepad2 to write our packages.
I am unfortunately not in a position to mandate a coding standard and enforce it (just a code monkey at this point) so I was hoping to find a free SQL code formatter that I can use myself, and possibly suggest to others on the team to use, to make my life easier.
I have considered writing a small application that would essentially take a file as input and reformat everything, but before I did this I figured I would ask if anyone new of such a tool that is already available and is free.
So does anyone now of any such tools available?
There is a free one online sqlformatter, also SQLinForm, personally i use TOAD and have done since before it was bought by Quest (10 years?)
VIM script
Aqua Data studio $ I use this one all the time.
I like TOAD for Oracle. It has a format feature that's decent. I see there's a freeware version, though I have not used it.
Toad for Oracle
nicest, most mature
$$$

Toad for Oracle, free version
free
this will do what you want
limitations are related to number of connections, size of data mods, etc.

Oracle SQL Developer (up and coming, free!)
free
from Oracle
cross platform

I had the exact same experience from Day One working with Oracle stored procedures - "I have to use NOTEPAD?! Oh HELL no."
So I hopped on the internets and what I found were people saying "Hey, I have to create stored procedures in Oracle, isn't there anything better than NOTEPAD?!"
And the canonical answer was: "Download TOAD, you'll be glad you did". So I followed their advice, was very happy with it, and I'm pleased (if a bit amazed) to see it is still a popular answer.
