Oracle SQL Tutorials

Hey, I've been contacted by a job recruiter about an entry level position requiring Java, Oracle SQL, and Javascript knowledge. I'm currently studying for the SCJP6 test, but are there any decent free crash courses on Oracle SQL? I have previously taken a 200 level and a 400 level college course on SQL syntax, I'm just really looking for a few tutorials that can sure up my knowledge of the basics and beyond. So far I've been going through "http://st-curriculum.oracle.com/tutorial/SQLDeveloper/index.htm", but I have a feeling I will need more than that to get me back up to speed. Any suggestions?...

Hi, and welcome to the forums.
Hey, I've been contacted by a job recruiter about an entry level position
requiring Java, Oracle SQL, and Javascript knowledge. I'm currently studying
for the SCJP6 test, but are there any decent free crash courses on Oracle SQL? You could do worse than follow the gurus here - particularly anything to
do with SQL and strings, SQL and dates and SQL and Regular Expressions
inter alia. CTEs are also of interest. Performance is also a biggie.
But, always remember, that while Oracle extensions are interesting and
powerful, you MUST get the basics right.
Look at the posts here - try and answer them yourself and then check back to see
if you've got it right.

How to execute command(program) from external file in Oracle SQL developer

Hi,
Does anyone know, Oracle SQL developer version 1.0.0.14.67 got any function that can execute command from an external file?
Example, i have 100 insert SQL inside a text file,
and i want to use Oracle SQL developer to execute it. How do i read from my text file? Thanks a lots.

If you're new to Oracle, do yourself and us a favour: read some tutorials and manuals. What sqldev's worth, better download the latest version (1.1.2), lots of fixes and enhancements...
Now for the big popper: to run an external file: @file
Best of luck,

ODM within Oracle SQL Developer 3.0 , no progress during Workflow creation

Hi,
I am trying to follow the instructions mentioned at http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r2/prod/bidw/datamining/ODM11gR2.htm
In the "Create a Workflow and Add a Data Source" section when i try to create a new New Workflow from the menu, the Oracle SQL Developer 3.0 just shows a progress bar pop up with message "Validating and Updating Workflow". The workflow does not gets created even after 6 hours while the progress bar keeps moving. I tried it several times but no luck and hence not able to move further.
Thanks in advance for the help.

Hi,
Are you using the SQL Developer 3.0 Production Release?
Can you try again, but this time launch SQL Developer using the following file:
C:\<SQLDEVELOPER INSTALL DIRECTORY>\sqldeveloper\sqldeveloper\bin\sqldeveloper.exe
This will display a console window prior to SQL Developer UI being displayed.
There may be some unexpected exception that is being thrown.
It should display in this console window and give us more information to go on.
It sounds like you were able to create a Project ok.
Did you have any issues during the install of the repository?
Did you happen to save the log?
If so, can you paste it in this thread?
THanks, Mark

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

APEX, Oracle SQL Creating Inventory System

I would like to use XE to create a database to track inventory/shipping/production/forecasting and do analytical reporting in a multi-user, multi production line environment, using bar code scanning, in a client server set up. How powerful/ flexible is APEX? Should I be looking at another reporting tool? Should I be looking to manage the data with Oracle SQL? Good books to recommend that include the basics through complex apps?
Thank you.
Wade

Hi Wade,
Good books to recommend that include the basics through complex apps?You may want to have a look here at "Application Express Documentation and Tutorials" here: http://www.oracle.com/technology/products/database/application_express/html/doc.html
The best APEX book (personal opinion) is not out yet, but you can already pre-order it at Amazon. The title "Pro Oracle Application Express" by John Scott (Jes from the forums).
Thanks,
Dimitri

Copying from Oracle SQL Developer to Microsoft Word doesn't retain formatting (Font,colors etc)

Copying from Oracle SQL Developer Worksheet doesn't retain formatting (font,color etc...)in Microsoft Word but copying from other programs such as
visual studio, chrome browser etc works fine. This doesn't work even after changed the setting to Keep Source formatting of Options-> Copy and Paste Settings

Hi,
I notice that you have cross posted in Answers forum and Oracle forum. Have you tried Mr. Peter's suggestion?
Then, I recommend we check the Word settings:
1. Go to: Options > Advanced > Cut, Copy and Paste
2. Make sure that Use smart cut and paste is ticked.
3. Click the Settings button next to this option
4. Make sure that Smart Style
Behavior is checked.
If the issue still exists, please upload a sample through One Drive, I want to test.

Unable to connect to Oracle Database using Oracle Sql developer 2.1.1.64

Hi Everyone,
I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:

However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.
My TNSNAMES .ora file is as follows:

I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad 10.5.0.41. It give me the following error:
ORA 12537 : TNS Connection closed
Thanks for your patience and help in advance.

Problem with java.sql.Clob and oracle.sql.CLOB

Hi,
I am using oracle9i and SAP web application server. I am getClob method and storing that in java.sql.Clob and using the getClass().getName() I am getting the class name as oracle.sql.CLOB. But when I am trying to cast this to oracle.sql.CLOB i am getting ClassCastException. The code is given below
java.sql.Clob lOracleClob = lResultSet.getClob(lColIndex + 1);
lPrintWriter = new PrintWriter(new BufferedWriter (((oracle.sql.CLOB) lOracleClob).getCharacterOutputStream()));
lResourceStatus = true;
can anybody please tell me the what is the problem with this and solution.
thanks,
Ashok.

Hi Ashok
You can get a "ClassCastException" when the JVM doesn't have access to the specific class (in your case, "oracle.sql.CLOB").
Just check your classpath and see if you are referring to the correct jar files.

Oracle SQL Developer error - "The file-based source procedure Name is not present in the database."

I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name> is not present in the database. Was it compiled?'
instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

Sounds like you do not have the correct privileges. What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest? If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
The role SELECT_CATALOG_ROLE
The system privilege SELECT ANY DICTIONARY
And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
The role EXECUTE_CATALOG_ROLE
The system privilege EXECUTE ANY PROCEDURE
Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.
Best wishes,
Gary

Can we use different Databases (Oracle & SQL Server) in one report?

Post Author: venki5star
CA Forum: .NET
Hi there.
Can we use different databases (Oracle & SQL Server) in a same report?
If possible how?
Another question,
Can we change the Provider Name at runtime of the given report. If so the above question is useless...
Thanks in Advance.

I tried this using Oracle Provider for OLEDB (the one that supplied by Oracle Client) and Crystal Reports 9. you can drag the column into designer but the image does not appear in preview.
I guess it's because CR does not recognized it as image, and there are no information that the blob data is an image at all.
