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 Neo4j

CData ODBC Driver for Neo4j supports connections to self-managed Neo4j instances via the HTTP API. To connect, set the following connection properties:

• Server: The server hosting the Neo4j instance. An HTTP or HTTPS protocol prefix may be optionally prepended to the server name or address.
• Port: The port on which the Neo4j service is running. The provider connects to HTTP (7474) port by default. If connecting over HTTPS, supply the HTTPS port for the Neo4j instance specified in Server.
• User: The username of the user using the Neo4j instance.
• Password: The password of the user using the Neo4j instance.
• Database: The database to target in the Neo4j instance. Defaults to "Neo4j".

Note that the CData ODBC Driver for Neo4j does not support connections to cloud Neo4j instances like those of AuraDB and AuraDS.
