The ODBC driver lets you define information for connecting to databases in SQL Server, including the directory source name (DSN), directory, driver of the database, and the ID and password of the user.

There are ODBC drivers for Microsoft ® SQL Server™, Microsoft Access, Oracle ® and many others.

Therefore, both ODBC Administrator tools display all user DSNs.įor more information about registry redirection, see Registry Redirector.Create an ODBC data source on 64-bit computersĪn ODBC Open Database Connectivity driver is a software standard that lets different applications share data. Registry redirection is not enabled for this registry subkey. User DSNs are stored in the following registry subkey:
Similarly, the 32-bit ODBC Administrator tool does not display system DSNs that use 64-bit drivers. Also, the 64-bit ODBC Administrator tool does not display system DSNs that use 32-bit drivers. Similarly, the 32-bit ODBC Administrator tool does not display system DSNs that are created by the 64-bit ODBC Administrator tool. The 64-bit ODBC Administrator tool does not display system DSNs that are created by the 32-bit ODBC Administrator tool. Therefore, system DSNs for 32-bit drivers and for 64-bit drivers are separated. Registry redirection is enabled for this registry subkey. HKEY_LOCAL_MACHINE\Software\ODBC\ODBC.INI System DSNs are stored in the following registry subkey: You can use the 32-bit ODBC Administrator tool to manage user DSNs and system DSNs that are used by WOW64 processes. You must directly invoke the 32-bit ODBC Administrator tool from the SysWoW64 folder. On a 64-bit operating system, the 32-bit ODBC Administrator tool is used for Windows on Windows 64 (WOW64) processes. The 64-bit ODBC Administrator tool can be invoked from Control Panel to manage user DSNs and system DSNs that are used by 64-bit processes. To indicate the type of DSN, you can add '_32' to the 32-bit user DSNs and '_64' to the 64-bit user DSNs. If you build and then run an application as a 32-bit application on a 64-bit operating system, you must create the ODBC data source by using the ODBC Administrator tool in %windir%\SysWOW64\odbcad32.exe. To work around this problem, use the appropriate version of the ODBC Administrator tool. To maintain backward compatibility, no resolution for this problem is currently available. Therefore, user DSNs are visible in both the 32-bit and 64-bit versions of the ODBC Administrator tool. The user DSNs are stored under the following registry subkey:
However, if you make a connection through this 32-bit user DSN, you receive the error message that is mentioned earlier in this section. The SQLDataSources function that is called in a 64-bit application returns this 32-bit user DSN. This driver does not have a corresponding 64-bit version.
You create a user DSN for the 32-bit driver 'Microsoft Access Driver (*.mdb)'. Therefore, if the application makes a connection by using a user DSN that is returned from the SQLDataSources function, you may receive the following error message:ĭata source name not found and no default driver specifiedįor example, consider the following scenario. Similarly, the SQLDataSources function that is called in a 64-bit application returns only system DSNs for 64-bit drivers but returns user DSNs for both 32-bit drivers and 64-bit drivers.
The SQLDataSources function that is called in a 32-bit application returns only system DSNs for 32-bit drivers but returns user DSNs for both 32-bit drivers and 64-bit drivers. The SQLDataSources function returns all versions of user DSNs, regardless of the architecture of the application. The 64-bit version of the ODBC Administrator tool displays 64-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs. The 32-bit version of the ODBC Administrator tool displays 32-bit system DSNs, 32-bit user DSNs, and 64-bit user DSNs. The Odbcad32.exe file displays the following types of data source names (DSNs):
