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

To connect to Neo4j, you have the following options:

If you are connecting to Neo4j AuraDB, you must use the Query API.

If you are connecting to Self-hosted Neo4j you can choose between the Query API and the HTTP API, depending on your version.

Connecting to Self-hosted Neo4j

Query API

To connect to Neo4j instances via the Query API, set the following connection properties:

• API: Set this to Query.
• 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. Self-managed instances have a default port of 7474 for the Query API. 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.

HTTP API

To connect to Neo4j instances via the HTTP API, set the following connection properties:

• API: Set this to HTTP.
• 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.

Connecting to Neo4j AuraDB

Neo4j AuraDB

To connect to Neo4j Aura instances, the required properties will be the same as the Query API configuration above. Notes on finding property values are below.

• API: Set this to Query.
• Server: Found in Query API URL in the Inspect menu of the instance in the Neo4j Aura cloud console. Nothing after Neo4j.io should be provided.
• Port: Set this to 443.
• User: The username of the user using the Neo4j instance.
• Password: Provided only once when creating the instance or when a new user is invited.
• Database: Currently, Neo4j Aura deployments do not allow changing the database name from the default value of Neo4j.
