Replicate Oracle SCM Data from PowerShell

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

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

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

Create an ODBC Data Source for Oracle SCM

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.

The following connection properties are required to connect to Oracle SCM data.

• Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
• User: The username of your Oracle Cloud service account.
• Password: The password of your Oracle Cloud service account.

Connect to Oracle SCM

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

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

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

Retrieve Oracle SCM Data

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