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

Access Oracle databases from virtually anywhere through a standard ODBC Driver interface.

Replicate Oracle Data from PowerShell


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



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

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

You can also write PowerShell code to execute create, read, update, and delete (CRUD) operations. See the examples below.

Create an ODBC Data Source for Oracle

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 Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

  • Port: The port used to connect to the server hosting the Oracle database.
  • User: The user Id provided for authentication with the Oracle database.
  • Password: The password provided for authentication with the Oracle database.
  • Service Name: The service name of the Oracle database.

Connect to Oracle

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

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

Back Up Oracle 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 " + $Customers $cmd = New-Object System.Data.Odbc.OdbcCommand($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 Oracle 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 CRUD commands to Oracle through the .NET Framework Provider for ODBC:

Retrieve Oracle Data

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

Update Oracle Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Customers SET Country='US' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Insert Oracle Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Customers SET Country='US' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Delete Oracle Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("DELETE FROM Customers WHERE Id = @myid", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()
