problems in inserting spanish words in oracle db - oracle

Is there a way to insert spanish words into the Oracle table - like 'España'.
When I try to insert it, it either takes the ASCII counterpart of it or replaces the 'ñ' with a '?'.
Has anyone done this before or knows a work around for it?
I found something while googling they told we have to mention spanish character set in init.ora file. I don't know how to do this and also setting nls_settings for client. I am using toad to connect to server which is located in UK.
Please help me in solving this problem.

First, you should check if the database was created with a character set that includes the Spanish characters that you want inserted. For versions of Oracle starting with 9i the wizards by default create the database using Unicode, so it shouldn't be a problem. But if the database wasn't created by you, this should be the first thing to check with the DBA that created it.
Which version of the Oracle server are you connecting to?
Which version of the Oracle client are you using? Which kind of Oracle client (OCI, JDBC, .NET)?
If the database was properly created it can be a problem related to the client platform.
And this is not simple to diagnose without information about the client OS, database client libraries that you are using and their configurations related to Natural Language Support.
So, I will point you to an Oracle FAQ related to this issue. It is a lot of material to read but it worths your time.

Is Oracle Database Supported in Joomla?

I would like to use Oracle database instead of MySQL in Joomla. Is this possible with Joomla, is there a workaround or a solution on how to implement Oracle database with Joomla? Any information will be greatly appreciated.
It is said that it can be done, but it is not a job for beginners and took those guys 3 working days to do it.
Here's why that combination doesn't work by default:
The database and table creation script does not work without modification.
The connection and the database class are written to connect to MySQL and not to Oracle (so they all use MySQL functions).
Some of the extensions use native MySQL functions directly, instead of connecting using the Joomla Database interface (class).
This is what they did to make it work:
We fix the SQL installation script to accommodate the Oracle database in case of a new installation. In case of an existing installation, we export all the database, as well as its data to a SQL file, and then we modify the SQL file (using find and replace) to make it work with an Oracle database.
We load the modified installation file or the modified exported SQL file into the Oracle database.
We then create a copy of the Joomla database class, and then we modify all the functions to work with Oracle instead of MySQL.
We ensure that the Oracle drivers are properly installed and loaded by the php.ini file.
We rename the original MySQL database (you will know in the next step why) to something like database_name_old.
We switch to the new database class and fully test the website to see if some extensions are not working. If an extension ceases to work then it is a sign that this extensions is calling the original MySQL database (which no longer exists because it was renamed) directly.
Hopefully, you aren't a beginner and those guidelines will help you do it. Otherwise, check how much it might cost by visiting the page.

SSIS 2008 R2 - Convert Oracle Character set data (with french accent)

I'm trying to extract data out of an Oracle database that is configured with the following:
NLS_CHARACTERSET EE8ISO8859P2
NLS_NCHAR_CHARACTERSET AL16UTF16
I'm working with SSIS 2008 R2 Standard (had to install Oracle 11g Client). Some accent are properly interpreted (e.g: é) but some are received as weird character and I can't find any way to convert them properly :( The Oracle database is used by our ERP that serves many countries around the world which probably explains the character set choice (I'm not debating if it's a good one or not, I'm a SQL Server guy, not Oracle).
I've tried different approach to extract the data from Oracle, none of which succeeded. I thought I could simply use something as:
SELECT CONVERT(FIELDNAME,'UTF8','EE8ISO8859P2') FROM xxx
Without success.. In my ERP I can see the following value:
"modèle" which is read "modcle" with the previous query through SSIS.
I kinda feel that there's no way I'm gonna get the proper data unless there's some magic formula that can be used. Any help would be appreciated.
Thank you.
All you need to do is set your NLS parameters using some ALTER SESSION commands.
Guess the parameter you need to change would be NLS_LANG
See this page for more information:

Strangely, I helped one of my teammates today to sort in Swedish using this. Hope it helps you too.

MS Access to Oracle database

I am developing an ASP.net application with Access database. I need to convert this Access database to Oracle. How can I do that?
I saw two options
Migrating the access database to Oracle through MIGRATION WIZARD in SQL developer
In Oracle, just creating a new connection with existing MS Access database and then converting to oracle.
Kindly let me know the best solution for this
thanks in advance,
Arjun
The two choices you proffer could be rewritten like this:
Use an automated tool written by experts
Do it the hard way and figure it out for myself
This is a personal, even philosophical, choice. Do you need to get the task done quickly? Or do you want to learn something along the way?
TRY IT and then tell us.
My experience integrating all things oracle with all things microsoft has always been complicated, and a lot of manual intervention was required.
It also depends on the complexity of your existing access database, if it's only one table, then you can grab that table sql, correct it for nvarchar -> varchar2 fields and datapump the data into oracle.
If Access has 1000+ tables I would suggest getting a professional to do it. Any reasonable dba should handle it no problem.
Please check the solution at Insert into from ms access to oracle db
You can customize the code based on your requirement. You can bundle the whole code into one class and prepare it as exe application.

Oracle Connection String With Windows Authentication

We have a requirement to make our products work on Oracle as well as SQL Server (around which they were originally built). Unfortunately we don't have any in house Oracle development experience to speak of but as a senior dev it has fallen to me to lead the project. So far I have managed to make our app connect to an Oracle database (I'm using Oracle XE 11.2) by using the following connection string:
Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=VS010-ORA11GR1)(PORT=1523))(CONNECT_DATA=(SERVICE_NAME=DEVORA)));User Id=dbo;Password=dbo;
The reason we decided to use this type of connection string is because we do not want to rely on changing tnsnames.ora on every client machine. However, as you can see this specifies an Oracle user and associated password. We also need to provide the ability to use the equivalent of SQL Server integrated security.
According to the literature I have read, to do this I simply need to specify / as the user id and then omit the password portion (as this is ignored anyway for Windows authentication). I also created the user in Oracle, making sure it matched the Windows user, with the following snippets:
CREATE USER "OPS$<DOMAIN>\<user>" IDENTIFIED EXTERNALLY;
GRANT CONNECT,RESOURCE TO "OPS$<DOMAIN>\<user>";
I also checked that the sqlnet.ora file on my local machine which hosts the XE instance and my dev environment contained the line:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
I understood that this would enable my app to connect to the Oracle database uing Windows Authentication. However what actually happens is that I get the following Oracle error message:
ORA-01005: null password given; logon denied
this doesn't make much sense because of course its null - it's supposed to be, according to the tutorials I've read.
The app targets .Net Framework 3.5, we are using the System.Data.OracleProvider and the actual connecting and so on is handled by Enterprise Library 5. Incidentally, I am aware of the deprecation of the OracleClient component but I just want this to work before I go into the extra complexities of changing providers.
Can anyone tell me what I'm missing? Have I chosen the wrong type of connection string? I apologise for any basic mistakes but I have always managed to avoid Oracle until now so my knowledge of it is close to zero.
Many thanks
I had the same problem and solved after adding this to conn. string:
Integrated Security=yes
To expand on the answer above by #Stikut. I tested this out with NHibernate 3.3.3.GA and it works.
user id=/;password=;Integrated Security=yes

How to retrieve Oracle server collation in order to set up linked server

After searching here and on the web, I finally decided to post the question. I am running an SQL 2000 server, and linked an Oracle 9i server. Everything works fine when I run queries, and even updates and inserts from and to the Oracle Linked server (using both Microsoft OLE DB driver and Oracle OLE DB driver) using the OPENQUERY approach.
The problem is that, in order to clean code a bit, I want to use four part names in my queries. I am doing this also when querying other SQL linked servers.
But when I run the queries against Oracle using four part names I get this error: ( I am translating the error message from spanish. Probably the original message in english id different)
ERROR: OLE DB 'MSDAORA' returned an invalid column definition.
Error Code: 7318
Digging a bit, I learned that this is probably related to nos having the right collation name set in the linked server properties.
Now... I am not an Oracle expert, so I need to find out what collation is the schema I connect to using in Oracle (apps... yes, I know, I know... )
So, the plain question is... How do I find out what collation Oracle is using? I have access to the Oracle server via Toad... is there any query I can run in order to find this out?
Thanks!
I think you're looking for the NLS settings, which you can find from these views:
V$NLS_PARAMETERS — "Current values"
NLS_DATABASE_PARAMETERS — What the database was created with.
NLS_INSTANCE_PARAMETERS — From changes by ALTER SYSTEM
NLS_SESSION_PARAMETERS — Combined, plus ALTER SESSION
V$PARAMETER — System parameters, where a lot of this is changed (contains all kinds of stuff)
The documentation is rather lacking here (or, quite likely, I couldn't find the right document), but this should get you what you want.
You will probably have to log in as SYSDBA to read some of these views.
