PowerShell Scripting to Replicate Amazon Marketplace Data to MySQL

The CData Cmdlets for Amazon Marketplace offer live access to Amazon Marketplace data from within PowerShell. Using PowerShell scripts, you can easily automate regular tasks like data replication. This article will walk through using the CData Cmdlets for Amazon Marketplace and the CData Cmdlets for MySQL in PowerShell to replicate Amazon Marketplace data to a MySQL database.

After obtaining the needed connection properties, accessing Amazon Marketplace data in PowerShell and preparing for replication consists of four basic steps.

To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.

Collecting Amazon Marketplace Data

1. Install the module:

   Install-Module AmazonMarketplaceCmdlets

2. Connect to Amazon Marketplace:

   $amazonmarketplace = Connect-AmazonMarketplace -AWS Access Key Id $AWS Access Key Id -AWS Secret Key $AWS Secret Key -MWS Auth Token $MWS Auth Token -Seller Id $Seller Id -Marketplace $Marketplace

3. Retrieve the data from a specific resource:

   $data = Select-AmazonMarketplace -Connection $amazonmarketplace -Table "Orders"

   You can also use the Invoke-AmazonMarketplace cmdlet to execute pure SQL-92 statements:

   $data = Invoke-AmazonMarketplace -Connection $amazonmarketplace -Query 'SELECT * FROM Orders WHERE IsReplacementOrder = @IsReplacementOrder' -Params @{'@IsReplacementOrder'='True'}

4. Save a list of the column names from the returned data.

   $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name

Inserting Amazon Marketplace Data into the MySQL Database

With the data and column names collected, you are ready to replicate the data into a MySQL database.

1. Install the module:

   Install-Module MySQLCmdlets

2. Connect to MySQL, using the server address and port of the MySQL server, valid user credentials, and a specific database with the table in which the data will be replicated:

   $mysql = Connect-MySQL -User $User -Password $Password -Database $Database -Server $Server -Port $Port

3. Loop through the Amazon Marketplace data, store the values, and use the Add-MySQL cmdlet to insert the data into the MySQL database, one row at a time. In this example, the table will need to have the same name as the Amazon Marketplace resource (Orders) and to exist in the database.

   $data | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Orders" -Columns $columns -Values $values }

You have now replicated your Amazon Marketplace data to a MySQL database. This gives you freedom to work with Amazon Marketplace data in the same way that you work with other MySQL tables, whether that is performing analytics, building reports, or other business functions.

Notes

• Once you have connected to Amazon Marketplace and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

  Select-AmazonMarketplace -Connection $amazonmarketplace -Table "Orders" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Orders" -Columns $columns -Values $values }

• If you wish to replicate the Amazon Marketplace data to another database using another PowerShell module, you will want to exclude the Columns, Connection, and Table columns from the data returned by the Select-AmazonMarketplace cmdlet since those columns are used to help pipe data from one CData cmdlet to another:

  $columns = ($data | Get-Member -MemberType NoteProperty | Select-Object -Property Name).Name | ? {$_ -NotIn @('Columns','Connection','Table')}
