I'm in need of a functional OleDB data provider for PostgreSQL. It should be similar to the ODBC provider for MySQL. See http://dev.mysql.com/downloads/connector/odbc/5.1.html
The postgres software catalog has some providers on there.
dotConnect for PostgreSQL (from Devart) offers a pretty good one. It is fast and works. The free version will give you your basic ADO.net support, the pay offers everything else. ODBC doesn't have a free version.

Adding the direct link to the ODBC connector as it is on a separate page.
https://www.devart.com/odbc/postgresql/
If you want to check the last version of ODBC for PosgreSQL :
http://www.postgresql.org/ftp/odbc/versions/
Enter in the "msi" folder for the installer.
But be careful, when you are using ODBC, there is a 32bits and a 64bits version. So choose the right one.

Has anyone managed to use Postgresql as a datasource for SSAS? The Postgresql .NET connector seems promising, but the SSAS view wizard does not seem to be able to see the tables in the database.
Try using the ODBC connector. I've had success getting other tools to connect to PG using it. The EnterpriseDB installers not only include a well packaged, working version of PG for windows, they include working, correctly installed drivers.

try pg_bulkload for load from via c# & from mssql to pgsql
copy & bcp (ssis) for second direction (pgsql->ssas)

It is actually possible to hack the Postgresql .NET connector and implement a "MSSQL compatibility mode", where the [ and ] around tables and schema names are removed. Using this, the list of tables does not appear in MS SSAS, but it is possible to replace them by views.
I have installed Oracle 10g and now want to install 11g also...How can I do it?.. I know that ORACLE_HOME environment variable need to be configured for each "oracle"..
Can you describe me steps how to do this?
Thank you very much in previous.
Thank you It helped me so much...
The most important is that I should have chosen %ORACLE_HOME% like %ORACLE_BASE%...
Just %ORACLE_BASE% should be the same...And it works.
There's ususally not a lot of reasons why Oracle databases of different versions cannot run on the same machine, be it Windows or Linux/Unix. Reasons can be if you run Clustering software, which may not be of a lower version than any database version involved. Similar with Oracle Grid or Cloud. Other than that, I can't really think of reasons, but there may be excpetions, linked to specific OS. Usage of ORACLE_HOME's is how Oracle manages different databases and versions. The Oracle Homes should be different for each database, the Oracle Base should be the same, the central inventory must be shared, and the ownership (of Oracle Homes) may be shared or separated. Sharing Oracle Home is an option for advanced users only.
I am using 64-bit version of windows 7. The only option I have in it, for creating Data SOurce is for Microsoft SQL server 2005. Hence, I am not in position to create ODBC for oracle. Is there any other way by which I can create the ODBC Data Source. I need the same for JDBC. Thank You.
Just install the Oracle Instant Client from the Oracle website.
To make Data Source for Oracle in 64 Bit windows operating system, go to
C:\Windows\SysWOW64\
And use odbcad32.exe file. Double click it and the option to make dsn will come, even for Oracle.
I am having Oracle 10g installed on my laptop and have downloaded ojdbc14.jar driver for the same. The problem is, my operating system is Windows 7, and I'm not having option to create a Data Source for Oracle since I m not having oracles driver installed. I m having option to create a Data Source for SQL server 6, but I want to get connected to Oracle. Please Help.
By 'Data Sources', I'm guessing that you mean Data Sources (ODBC), under Control Panel > Administrative Tools. Is this correct?
I've set up ODBC Data Sources that connect to Oracle databases before, but to do that I've needed the Oracle client to be installed. However, if you're having the full database installed on your laptop (as your question suggests), you won't need the client - that's only used to connect to databases running on other machines. I believe the full database contains everything in the client, so you should be able to set up an ODBC Data Source pointing to the database on your laptop once the database has been installed.
The ojdbc14.jar just contains the JDBC classes to talk to an Oracle database, and only programs written in Java (and other languages that run on the JVM such as Scala, Groovy or Clojure) can use it. This jar on its own not enough to be able to set up an ODBC data source.
Oracle currently has 1 version that is certified for windows 7. That version is 11.2. They have indicated that they plan to certify 10.2.0.5 if this happens there will likely be a patch that will be needed.
This is probably why the Data Source does not work, either ODBC or OLEDB.
Another possibility is that you have installed the 32bit version of Oracle and your OS is 64bit then you would need to use the 32bit Data Source administrative tools.
I have figured out the solution for my problem. All that I needed to do is put ojdbc14.jar file in my class path and then I was able to use it. Though by doing so, I needed to make some change in the code. I was no more able to use Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") instead I needed to use Class.forName("oracle.jdbc.OracleDriver") also instead of using my data source as "jdbc:odbc:somename" I needed to use jdbc:oracle:thin:#localhost:1521:xe.
I'm looking for an ADO.net 2.0 or later provider for Sybase database which seems to be known as Sybase ASE. To clarify, I'm interested in ASE, and not SQL Anywhere. Hopefully the provider will be included with the database, or free.
I can find mention of an ADO.net 1.1 provider; that's not what I want.
I can find mention of ODBC drivers and OLEDB providers; that's not what I want.
I've found the DataDirect ADO.net providers which are paid for; I guess that's the fallback position.
Thanks for your help
Having recently been down this road myself, I can only suggest that you wont find the answer through searching the net. If you are connecting to an ASE server, then you have a customer technical contact. Use that person, asking them to download the earlier mentioned Sybase 15 #ESD10.
From my experience (which I freely admit, was a bad one);
Sybase makes this sort of developer resource available to paying customers only.
The download, once you have it, will include a whole bunch of extras that you wont need. I still think that PowerDesigner is a great utility, but I think that what is included is a trial version, of limited long term value. I believe that what you want from the set is the OpenClient install, selecting the ADO.NET features.
I found the whole experience, from acquiring the developer resources (just identifying the right download was a struggle), to isolating out the two files necessary from the hundreds of installed files, to the fact that the install broke my existing RapidSql and DbArtisan installs, and finally that the current version goes no further than ADO.NET 2 provider support (you wont get EF wiring for example), to be truly frustrating.
No surprise then that I have not been able to find much support for ASE using nHibernate or subsonic either.
This question is fairly old but it seems to have gotten easier to get the ADO Connector.
Download the "Get a Free "Developer" Edition" from
http://scn.sap.com/community/developer-center/oltp-db
Choose Custom Install when given the option.
Only install the .Net ADO package from the custom install.
Reference the Sybase.AdoNet4.AseClient.dll in your solution from where the install put the files.
You should then be able perform queries, updates etc. in .NET by following the directions from here:
http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.sdk_12.5.1.adonet/html/adonet/DAFJEFIF.htm
As an alternative to the SAP/Sybase driver, we developed our own ADO.NET Core driver for ASE:
https://github.com/DataAction/AdoNetCore.AseClient
.NET Core was a key technology for us - in particular for AWS Lambda - and there is still no ADO.NET Core driver available from SAP/Sybase.
Our driver supports most of the SAP/Sybase ADO.NET features, aims to be a drop in replacement to the SAP/Sybase one for easy transition, and supports all of the .NET Frameworks you would care about.
You can get it on Nuget:
https://www.nuget.org/packages/AdoNetCore.AseClient
Sybase 15 #ESD10 has support for ADO.NET 2.0, according to this link at Sybase:

From the sybase website:
Sybase support for ADO.NET, OLE DB, and ODBC
Adaptive Server version 15.0 contains new ODBC and OLE DB drivers developed by Sybase. The third-party rebranded ODBC and OLE DB Driver Kits included with previous versions are no longer shipped.
The retired ODBC Driver Kit was installed in %SYBASE%\ODBC, and registered with the ODBC Driver Manager as “Sybase ASE ODBC Driver”. The new ASE ODBC Driver by Sybase is installed in %SYBASE%\DataAccess\ODBC, and registered as “Adaptive Server Enterprise”. The version shipping with Adaptive Server and SDK 15.0 is version 15.0.0.50.
The retired OLE DB Driver Kit was installed in %SYBASE%\OLEDB, and used the provider short name of “Sybase.ASEOLEDBProvider” and the long name of “Sybase ASE OLE DB Provider”. The new ASE OLE DB Provider by Sybase is installed in %SYBASE%\DataAccess\OLEDB, and uses provider short name “ASEOLEDB”. The version shipping with SDK 15.0 is version 15.0.0.51.
Sybase recommends that you start your migration process the new ODBC and OLE DB drivers as soon as possible. New features introduced in Adaptive Server 15.0 are supported only by the new drivers.
See “New Features for OpenServer 15.0 and SDK 15.0 for Windows, Linux and UNIX”, for instructions on migrating to the new drivers.
