How can I install ms sql client on my windows 7 machine ?
Because without this driver error is "Provider cannot be found"
I am using mssql server 2005 on my Win XP, I am fail to install dot net framework 2 on windows 7 client.
Microsoft SQL Server Native Client contains the SQL OLE DB provider and SQL ODBC driver in one native dynamic link library (DLL) supporting applications using native-code APIs (ODBC, OLE DB and ADO) to Microsoft SQL Server.

Despite that OLE DB and ADO.NET are newer than ODBC potentially, I've heard that ODBC connections to Oracle are potentially faster within SSIS.
I'm trying to set up a simple ODBC connection to an Oracle DB in SSIS
The OLE DB / ADO.Net connections were easy. I entered the credentials and boom, connected.
ODBC proves very difficult. I'm running Windows 10 64 bit. Visual Studio 2015 (I believe the designer for SSIS was only meant to initially play with 32-bit ODBC connections). Oracle is version 12c.
So ... I did the convoluted Oracle driver install. Downloaded Oracle basic light express + ODBC. Put them in the same directory. Ran odbc.install.exe WITH admin privileges. Finally got the Oracle driver to show up in Microsoft ODBC (32 or 64, ended up downloading both eventually). I test the connection in Microsoft ODBC setup? Success!! NOOOOW. .. enter Visual studio. Set up connection --- test --- FAIL! Some cryptic error .... 127 ... the "oracle" in quora32.dll can't be found.
Are Microsoft Drivers for Oracle still available for download?
32-bit vs 64-bit
I think that the main cause of the problem is that Visual studio is a 32-bit application and the ODBC driver installed is 64-bit. On the other hand the operating system is 64-bit then it will work normally. Check the following links for more information:

Attunity connectors
I really didn't tried connecting to Oracle using ODBC, but if your goal is to achieve higher performance then the fastest way to connect to Oracle from SSIS is using Attunity high speed connectors for Oracle that have been selected by Microsoft to be included with SQL Server Integration Services (SSIS).
Check the following links for more information:

Oracle provider for Oledb missing in VS 2015 Shell
SSIS not running in parallel with OraOLEDB.Oracle.1 Provider
As noted in various ways on this question, the VS IDE (and its typical testing environment) is 32-bit, even when installed/running on 64-bit Windows, or when building for use/deployment on 64-bit Windows. My employer has a knowledgebase article discussing this.
Also, SQL Server, SSIS, and VS are always OLE DB or ADO.NET clients; they don't actually speak ODBC directly. When you tell either SQL Server, SSIS, or VS to connect to an ODBC driver or ODBC DSN, they invisibly use the Microsoft OLE DB [Bridge] Provider for ODBC Drivers for that connection.
The easiest way to work around all this, given that you explicitly want to use ODBC, is to install both 32-bit and 64-bit variants of all OLE DB (including the Bridge Provider) and ODBC components (and any libraries on which they depend, such as OCI or Oracle Instant Client), and to configure a pair of ODBC System DSNs (not User DSNs, for several reasons), one each 32-bit and 64-bit, which are named and configured identically excepting only the driver library.
This strategy works whether you're using ODBC drivers from my employer (which might be the "12-15x faster" ones referenced previously? if so, it's important to note that Enterprise Edition "concurrent users" is about actively connected clients, not installed seats), from another third-party, or from Oracle themselves.
I have installed the vb6 and oracle 11 g client(instantclient_11_2) on windows 10.
I created one odbc connection and now trying to connect oracle db but its giving error while connecting the db using vb6 form.
Error :"Error while trying to retrieve text for error ORA-01019"
I am using the connection string like :
sconnstring = "DRIVER={Microsoft ODBC for Oracle};SERVER = servername;uid = user id;pwd= password}"
When creating the ODBC connection use ODBC 32 ...under windows\sysWow
The Microsoft ODBC driver "Microsoft ODBC for Oracle" is deprecated for ages, you should not use it anymore.
Download and install the "ODBC Package" from Instant Client Downloads for Microsoft Windows 32-bit, then it should work.
instant client for microsoft odbc is not available for Windows-10 operating system.
Then in that case for windows-10 we need to use Oracle ODBC client 12 version for odbc connection.Its working for me.
Newbi to oracle and its versions and .NET providers, but did some investigation.
I'm trying to add Oracle connection to the visual studio server Explorer (before setting up the Entity Framework 6 for oracle).
System preferences:
Windows 10 enterprise - 64 bit operating system
Visual Studio 2015
Oracle Data Access Components (ODAC) which includes Oracle developer Tools for Visual Studio: ODAC12C - 12.2.0.1 - it is suitable to 64 bit !
The DB is located in a remote machine and I can see the DB objects using the Oracle SQL developer. It uses the TNSNames file to locate the DBs.
when trying to "add connection" in the visual studio server explorer:
Select Data Source: Oracle DataBase
Data Provider:.NET framework data provider for Oracle.
It claims that:
"This provider is deprecated and should not be used. Instead download
Oracle Developer tools for visual studio for comprehensive integration
with Oracle database."
The problem is that the mentioned above reference links to a 32-bit Oracle Data Access Components (ODAC) bundle which includes "Oracle Developer Tools for Visual Studio". The same shXX happens when choosing .NET framework data provider for OLEDB.
Either I don't see the relevant provider in the list or there is a problem.
After inserting Server name, User name and Password in the "Add connection" dialog box, I get this error message:
"Attempt to load Oracle Client libraries threw BadImageFormatException.
This problem will occur when running 64 bit mode with the 32 bit Oracle Client components installed"
What am I doing wrong ?
Is this the way of defining connection string when I have a TNSNames file ?
Microsoft .NET Framework Data Provider for Oracle is different to Microsoft OLE DB Provider for Oracle which is different to Oracle Data Access (which can be Oracle Data Provider for .NET or Oracle Data Provider for .NET Managed Driver or Oracle Provider for OLE DB, depending on which one you installed), see How to connect to Oracle 11 database from . net
Visual Studio 2015 is 32-bit, when you like to connect to an Oracle database directly from Visual Studio Explorer then you have to download/install the 32-bit version of ODAC - and also install 32-bit Oracle Client.
In case you like to use also 64-bit Oracle Client and drivers follow this instruction: BadImageFormatException. This will occur when running in 64 bit mode with the 32 bit Oracle client components installed
I have server under Windows Server 2003 with Oracle 10 32bit. There are several ODBC data sources configured in ODBC Data Source Administrator.
Now I need to move all that system to Windows Server 2008 R2 x64.
I've installed OS, Oracle server 12c x64, Oracle client 12 x64.
Now I need to configure my ODBC data sources, but there is no Microsoft ODBC for Oracle driver.
Where can I find this driver to configure ODBC data source?
(I've tried 32bit tool from SystemWOW64, it has this driver but shows me exception "The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle version 7.3 (or greater) clien costware installation." As far as I could say it looks for 32bit client, but there is no such)
"Microsoft ODBC for Oracle" does not exist for 64 bit. Microsoft provides only a 32-bit version.
You have to download and install the driver from Oracle: ODBC
Developer Center or
64-bit Oracle Data Access Components (ODAC) Downloads
The 32-bit ODBC driver (no matter if from Microsoft or from Oracle) does not work together with an 64-bit Oracle Client, the architectures have to match.
I have MS VS 2010 installed on my Windows 7 but, I don't have the SQL Server Native client installed in it.
After loading Visual Studio I do click menu Data / Transact-SQL Editor / New Query Connection.
The SQL Server 2008 R2 login dialog will show up, I type server name, select SQL Server authentication, type username and password and click connect. The connection is established and an editor window shows up and I'm ready to query!
I understand the SQL Server 2008 native client files are sqlncli10.dll, sqlnclir10.rll. I did search for these files in my entire hard drive and they weren't found.
So, how is Visual Studio 2010 connecting to SQL Server 2008 if I don't have the native client installed?
Is VS 2010, when connecting to SQL Server 2008, using .NET Framework assemblies?
The .NET Framework already contains the Sql Server (and other) Database clients.
Have a look at System.Data.SqlClient
If NO native client is installed, Visual Studio 2010 is using the .NET Framework version 4.0 to connect to SQL Server 2008 R2 when connecting through menu Data/Transact-SQL Editor/New Query Connection.
I verified and it is loading assembly System.Data.dll (located under C:\Windows\Microsoft.NET\Framework\v4.0.30319) to establish the connection to the server.
I have not installed the Native client 10.0 for SQL Server 2008 R2 and I'm not using it right now but, if installed, the native client files (sqlncli10.dll, sqlnclir10.rll, and s10ch_sqlncli.chm) should be found under
%SYSTEMROOT%\system32\
which are installed as part of the SQL Server installation.
There is also a redistributable installation program named sqlncli.msi, which should be found on the SQL Server installation CD under
%CD%\Setup\
The reference for installation details
http://msdn.microsoft.com/en-us/library/ms131321.aspx
And the reference for the SQL Server 2008 R2 Native Client Features
http://msdn.microsoft.com/en-us/library/ms131456.aspx
The key piece of information here is:
You do not need to install SQL Server Native Client on your client machine (in this case your dev box where Visual Studio is), in order for an application using ADO.Net, to connect to SQL Server.
The reason is as #dknaack said: the .Net framework contains the code required to make the connection. This is contained in System.Data.SqlClient.
SQL Native Client on the other hand is used by unmanaged applications to connection to SQL Server via either OleDB or ODBC providers.
In short:
System.Data.SqlClient - used for connections from managed code to SQL Server i.e an ADO.Net connection
SQL Server Native Client - used for connections from unmanaged code to SQL Server
Whilst you CAN connect to SQL Server from a managed app using SQL Server Native Client, it is not a recommended practice:
If you are developing a new application, it is recommended that you
consider using ADO.NET and the .NET Framework Data Provider for SQL
Server instead of SQL Server Native Client to access all the new
features of recent versions of SQL Server.
