I hope someone can help me...
The connection to a Oracle DB from QGIS works without problems.
Also the integration from a table into the project is no problem.
But when I open the Attribute Table, there are no attributes for the 55k datasets.
Attribute Table without attributes
Why is there nothing shown?
I don´t know if there is something wrong with the conenction...
Oracle Conenction
Is there some further Information needed for the connection?
Thank´s for your support.

I recently installed Datagrip to view my Company's Postgres database, however I am currently unable to view the tables in the different schemas by clicking on the schema name:
In the image, I've clicked to open and show the ab-testing schema, however nothing appears below it. This behavior is consistent across all of the schemas in the database. I am able to use the query editor to query tables in the schemas (assuming i know the table names), yet I cannot see the names in the left-side panel. I am using datagrip 2020.2
Thanks!
I had the same problem with a MySQL database. As a test, I used the MariaDB driver instead of the MySQL driver as usual. This was intentional and not an oversight, but it was not a good idea!
The tables, views and server objects were not displayed. Although I was able to display the tables and views after activating Schema Properties -> Advanced -> "Introspect using JDBC metadata", the server objects were not displayed. Working with the displayed tables and views was not possible in the usual way.
Only when I used the MySQL driver again, everything worked correctly again. The tables, views and server objects were displayed correctly and the work with it was possible in the usual way.
As a small quintessence I would like to recommend to all who "struggle" with similar problems to check your chosen drivers. Maybe the problem is caused by choosing the wrong driver, as it was in my case.
Whick kind of message do you get when instrospecting the schema?
I had a java.io.CharConversionException caused by a not valid UTF-8 string.
If this is the case, you can add the following VM option -Ddb2.jcc.charsetDecoderEncoder=3.
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.
does anyone know how to set up default "seeing" of specific tables after connecting to the DB? E.g. we have tables A,B,C,D and after connecting to the DB I want to see TAB with table A and TAB with table B.
Thank you
Sorry, this isn't possible today in Oracle SQL Developer.
You could submit an enhancement request to My Oracle Support or put in an idea to sqldeveloper.oracle.com
Is there a way to make Entity Framework 4.1 Code First NOT to drop database or the tables, not even if its changed? Im suppose to upgrade a LIVE site and I cant because of this. I seen some NuGet classes I can get but its to not drop database but tables, recreate tables on change ect.. i just do not want to do anything to the database or the tables.
In the startup of your application add this:
Database.SetInitializer<YourContextType>(null);
This should remove any initialization strategy.
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.
