Replicate PreEmptive Analytics Data from PowerShell

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



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

You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating PreEmptive Analytics data to other databases. This article shows how to replicate PreEmptive Analytics 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 PreEmptive Analytics

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 URL property should be set to the host and port where the PreEmptive Analytics Workbench is running, for example, http://127.0.0.1:88. The authentication scheme will vary depending upon how the Workbench is hosted and the authentication schemes enabled. It is suggested that you contact the server administrator to obtain login credentials and authentication scheme information.

Connect to PreEmptive Analytics

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

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

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

Retrieve PreEmptive Analytics Data

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

Update PreEmptive Analytics Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE FeaturesSummary SET Time='01/01/2015' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Insert PreEmptive Analytics Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO FeaturesSummary SET Time='01/01/2015' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Delete PreEmptive Analytics Data

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