Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
3. Click the System DSN tab.
4. Select the system data source and click Configure.
5. Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Ensuring Registry Access

The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:

1. Run the calling application as an administrator.
2. Connect via a User DSN instead of a System DSN.

Connecting to Azure Table Storage APIs

The driver will connect to the Azure Table Storage account specified by Account. By default, connections to the Azure Table Storage are secured via SSL, though this can be controlled through UseSSL. The authentication method to the Azure Table Storage is determined by the AuthScheme property.

Authenticating to Azure Table Storage

The following mechanisms may be used to authenticate.

Access Key

Set Account to the storage account name and set the AccessKey of the storage account to connect. Follow the steps below to obtain these values:

If using Storage as the Backend (default):

1. Log into the Azure portal and select Storage Accounts in the services menu on the left.
2. If you currently do not have any storage accounts, create one by clicking the Add button.
3. Click the link for the storage account you want to use and select Access Keys under Settings. The Access Keys window contains the storage account name and key (you can use either key1 or key2 to connect) that you will need to use in the driver. These properties map to the Account and AccessKey driver connection properties respectively.

If using CosmosDB as the Backend:

1. Log into the Azure portal and select Cosmos DB in the services menu on the left.
2. Click the link for the Cosmos DB account you want to use and select Connection String under Settings. The Connection String window contains the Cosmos DB account name and primary key that you will need to use in the driver. These properties map to the Account and AccessKey driver connection properties respectively.

Shared Access Signature

Set Account to the storage account name and set the SharedAccessSignature to a valid signature of a resource to connect to. The SharedAccessSignature may be generated with a tool such as Azure Storage Explorer.

Typically when SharedAccessSignature is used, the specific table to work with must also be specified via the Tables connection property. If no table is specified, a table listing will be attemped, but may fail due to a lack of permissions.
