I have a Microsoft Access database (.accdb extension) that I would like to query with SQL developer version 19.4. Is this possible? and how do I achieve this?
I am not planning on migrating the database, I would just like to be able to query it with SQL (as I am not familiar with Access).
When I create a new connection I don't have the possibility to select Access in a tab with this version of SQL developer. When I use an older version it is there, but it doesn't support the extension of my Access database.
I found this as well: Connecting MS Access to Oracle SQLDeveloper
But the suggestions done there are not suitable for me unfortunately.
No it's not possible.
We used to offer this functionality via a odbc-jdbc bridge, but that went away with Java 7 I believe.
We've not built native support for an Access JDBC driver.
If you can find a copy of SQL Developer version 3, you can do what you want, out-of-the-box.
FYI, sql developer 4.0.3 also has Access and can open Oracle 19c.
You may need the driver:
Microsoft Access Database Engine 2016 Redistributable
Then you can create a Linked Server using your accdb file as source.

With Visual Studio 2008 I'm trying to connect to an Oracle database using Oracle Provider to OLE DB (the only Oracle driver available in dropdown), and I'm having issues with it. So I'm trying to add other drivers to that VS2008 "Connection Manager" dropdown. Unfortunately, I only see the ones in this screenshot
How can I add other drivers to this dropdown? When I create an ODBC driver, I see several other Oracle drivers to choose from that I don't see in the VS2008 dropdown.
You installed more than one Oracle Client, this is always a bad idea. Usually there is no reason to install more than one Oracle Client, i.e. one each for 32-bit and 64-bit.
For OLE DB you cannot install more than one driver (per architecture), see Installation Considerations for Oracle Database Client:
You can install all Oracle components in multiple Oracle homes on the
same computer. However, some components can only support one active
instance at a time. This means that the current (latest) installation
renders the previous one inactive. These components are:
Oracle Administration Assistant for Windows
Oracle Provider for OLE DB
This is a limitation in COM. So, you cannot add other providers, at least no other Oracle Provider for OLE DB
You could use the Microsoft OLE DB Provider for Oracle (MSDAORA), however this has been deprecated for ages and it is really not recommended to use it.
Instead of OLE DB you could also use ODBC or use the Oracle Data Provider for .NET, you can download and install it from here: 32-bit Oracle Data Access Components (ODAC)
As far as I know Visual Studio 2008 supports only .NET Framework only up to version 3.5, thus you would have to use the Oracle Data Provider for .NET 2.0, version 4 will not work.
Maybe this list provides an overview for you: How to connect to Oracle 11 database from . net
If you like to get a list of all OLE DB providers which are installed on your machine, check this one: How to check the version of oracle provider for ole-db. OraOLEDB.Oracle provider
I am trying to install Oracle Developer Tools for Visual Studio 2015 so that I can connect to a remote 11g database from SSRS/Visual Studio Projects in general, from my dev machine. When I go to the downloads page, I see this:
So I went to Visual Studio to determine whether I already had ODT, and found this:
However, I don't think I installed this ODP, and it just came with the Visual Studio installation. Is there a way to uninstall this provider, or am I OK to just install the new ODT over top? Lastly, as I did more research for this post I became a little more unsure: does ODAC include ODP.net?
Thanks.
Microsoft OLE DB Provider for Oracle and .NET Framework Data Provider for Oracle are providers from Microsoft, i.e. they are part of your Windows installation.
Indeed, they are deprecated from many years, however there is no reason to remove them. They are just two little DLL's.
It is no problem to install Oracle Provider for OLE DB and Oracle Data Provider for .NET (ODP.NET) from Oracle, the drivers from Oracle and the drivers from Microsoft do not interfere with each other.
Yes, ODAC (Oracle Data Access Components) is a collection of various drivers, ODP.NET, OLE DB, ODBC and a few more.
Just a note, unless you use the ODP.NET Managed Driver all drivers mentioned above require an Oracle Client installation, typically an Oracle Instant Client. I think the Oracle Instant Client is also included in the ODAC package.
Maybe have a look at this post to get a little overview: How to connect to Oracle 11 database from . net
This might be a really dumb question... but in VS2013 when trying to add a local database to my Windows Forms Application Project the option is now shown in the C# items menu. The only DB that is available is a Service-Based DB. From what I understand, this is related to SQL Compact Edition but I do have SQL Server 2012 installed. Any ideas? Or are there any significant differences between the Local DB and Service-Based DB?
A service-based database is a database that is only accessed through a server. It uses an MDF data file, which is SQL Server format. To be able to connect to a SQL Server database the SQL Server service must be running, because it's that that processes your requests and access the data file.
A local database is one that is local to your application only. It uses an SDF data file, which is SQL Server CE (Compact Edition) format. There is no need to install a server to access an SDF database. You simply distribute the DLLs that constitute SSCE along with your app and access the data file directly.
You'd normally only use SSCE if the data was to be accessed by your app only and there was a relatively small amount of data. For your project you would use SQL Server. For testing purposes you can use the free Express Edition. When deployed you might still use SSEE or you might use a full version of SQL Server. Note that Microsoft include SSEE with their own RMS POS software. SSEE is limited to databases of 4GB though, so even if you start out with SSEE and it can handle the load, you may still have to upgrade at some point in the future based on data capacity.

for help on creating the database have a look at this tutorial it may be of some help.
Hope this info helps you :)
It turns out VS2013 dropped the .sdf format.
Is Microsoft dropping support for SDF database files in Visual Studio?
The answer is yes: Microsoft is silently dropping support (as usual IMHO) to Sql Compact Edition.
It started abandoning Sql CE 3.5 in Vs2012 It continued dropping Sql CE in Sql Management Studio 2012 and finally in VS2013
You can use CompactView or install SQL Server Compact Toolbox extension in VS2013 or (my prefered solution) use Sql management Studio 2008
UPDATE thanks to Nicolas' comment
As stated by Microsoft:
SQL Server compact edition is in deprecation mode with no new releases planned near future. Last release SQL CE 4.0SP1 (and earlier releases that are still in the support cycle) will continue to be supported through its lifecycle and Microsoft is committed to fix any major, production blocking issues found in these releases.
Have you tried adding your local database from inside the project? Have a look and see if you can add your database from datasources.
How do I connect to an Oracle Database that is not hosted on my loacal machine from visual studio. There seem to samy many different ways that I am getting confused. What kind of information would I need about the host machine and the database before I can proceed? Would I use ODBC or something else? Please help me out with this because I have spent weeks trawling the web and its very confusing.
You can use ODP.net which is Oracle's official middleware for .net applications.
Once installed, you can connect to a server by using one of the various connection mechanisms that Oracle supports: EZConnect, LDAP, TNSNames...
Once you can access the databases, you can use VS's server explorer to access the db objects
I've created an empty console application in Visual Studio 2010 and I'm attempting to add an Oracle (10g XE ) Data Connection via the Server Explorer. I'm using Oracle ODP .NET as the connector and I get the following error:
ORA-12560: TNS: Protocol Adapter Error
I can access Oracle without issue via the web interface or a console, but continually get this generic connection error in VS. I'm using the default installation of Oracle XE and running it locally.
Any suggestion on how to get this set up correctly ? Every tutorial I find works on the understanding that this connection succeeds. As such I'm struggling to find where to begin to troubleshoot. I'm comfortable with VS2010, but new to the way Oracle does things with their DB.
EDIT 1
While troubleshooting I've found this only happens with the Oracle Data Provider for .NET. Using the .NET Framework Data Provider for Oracle I am able to successfully connect.
EDIT 2
I cleaned up everything and installed 11g XE and the ODAC tools again and continue to get the same message. I realize the error is somewhat generic, I'd be happy to post more information if anyone thinks it helpful. The database is run locally, I can't imagine what kind of 'configuration' an express database would even need...
EDIT 3
The ODAC tools appear to install a 'production' version of Oracle 11 instead of the BETA version that I installed first. Almost appears as if the tool is installing another database ? I also appear to have two ORACLE_BASE locations and two TNSNAMES in what appear to be very similar folder hierarchies. Perhaps a more straightforward tutorial is the answer, Oracle's isn't very descriptive.
Oracle 10g XE seemed to be the problem. A full install of 11g (Full, not Express) took care of the problem entirely.
From here:
Possible fixes for the TNS-12560
include:
Get the latest patches for the SQL*Net client software.
Check your $ORACLE_HOME and $Path variables.
Check File permissions on the PC client.
Ensure that TNS_ADMIN is set correctly.
Check for firewall issues.
Check that the Windows database service is started. Verify teh
ORACLE_SID parameter is set correctly
in the registry.
Wow. I finally got this syntax to work.
I'm a Sql Server guy. I used Oracle back in the da day.
But I'm trying to do some Entity Framework and I said "You're not going to bed until you get Visual Studio 2012 and a edmx file to talk to Oracle.
Geeze.
Here is what I came up with:
Data Source:
Oracle Database (Oracle ODP.NET)
Data Source Name:
localhost:1521/orcl
User Name:
SYSTEM
change the default data source name to localhost.
