Neo4J Icon Neo4J ODBC Driver

The Neo4J ODBC Driver is a powerful tool that allows you to connect with live data from Neo4J, directly from any applications that support ODBC connectivity.

Access Neo4J data like you would a database - read Neo4J data through a standard ODBC Driver interface.

Replicate Neo4J Data from PowerShell


Write a quick PowerShell script to query Neo4J data. Use connectivity to the live data to replicate Neo4J data to SQL Server.



The CData ODBC Driver for Neo4J enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real Neo4J data with PowerShell.

You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating Neo4J data to other databases. This article shows how to replicate Neo4J data to SQL Server in 5 lines of code.

You can also write PowerShell code to download Neo4J data. See the examples below.

Create an ODBC Data Source for Neo4J

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To connect to Neo4j, set the following connection properties:

  • Server: The server hosting the Neo4j instance.
  • Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
  • User: The username of the user using the Neo4j instance.
  • Password: The password of the user using the Neo4j instance.

Connect to Neo4J

The code below shows how to use the DSN to initialize the connection to Neo4J data in PowerShell:

$conn = New-Object System.Data.Odbc.OdbcConnection $conn.ConnectionString = "DSN=CData Neo4j Source x64"

Back Up Neo4J Data to SQL Server

After you enable caching, you can use the code below to replicate data to SQL Server.

Set the following connection properties to configure the caching database:

  • CacheProvider: The name of the ADO.NET provider. This can be found in the Machine.config for your version of .NET. For example, to configure SQL Server, enter System.Data.SqlClient.

  • CacheConnection: The connection string of properties required to connect to the database. Below is an example for SQL Server:

    Server=localhost;Database=RSB;User Id=sqltest;Password=sqltest;

The SQL query in the example can be used to refresh the entire cached table, including its schema. Any already existing cache is deleted.

$conn.Open() # Create and execute the SQL Query $SQL = "CACHE DROP EXISTING SELECT * FROM " + $ProductCategory $cmd = New-Object System.Data.Odbc.OdbcCommand($sql,$conn) $count = $cmd.ExecuteNonQuery() $conn.Close()

The driver gives you complete control over the caching functionality. See the help documentation for more caching commands and usage examples. See the help documentation for steps to replicate to other databases.

Other Operations

To retrieve Neo4J data in PowerShell, call the Fill method of the OdbcDataAdapter method. To execute data manipulation commands, initialize the OdbcCommand object and then call ExecuteNonQuery. Below are some more examples commands to Neo4J through the .NET Framework Provider for ODBC:

Retrieve Neo4J Data

$sql="SELECT CategoryId, CategoryName from ProductCategory" $da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn) $dt= New-Object System.Data.DataTable $da.Fill($dt) $dt.Rows | foreach { $dt.Columns | foreach ($col in dt{ Write-Host $1[$_] } }
