PowerShell Scripting to Replicate Azure Table Data to MySQL

Write a simple PowerShell script to replicate Azure Table data to a MySQL database.

The CData Cmdlets for Azure Table offer live access to Azure Table 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 Azure Table and the CData Cmdlets for MySQL in PowerShell to replicate Azure Table data to a MySQL database.

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

Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

Collecting Azure Table Data

  1. Install the module:

    Install-Module AzureTablesCmdlets
  2. Connect to Azure Table:

    $azuretables = Connect-AzureTables -AccessKey $AccessKey -Account $Account
  3. Retrieve the data from a specific resource:

    $data = Select-AzureTables -Connection $azuretables -Table "NorthwindProducts"

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

    $data = Invoke-AzureTables -Connection $azuretables -Query 'SELECT * FROM NorthwindProducts WHERE ShipCity = @ShipCity' -Params @{'@ShipCity'='New York'}
  4. Save a list of the column names from the returned data.

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

Inserting Azure Table 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 Azure Table 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 Azure Table resource (NorthwindProducts) and to exist in the database.

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

You have now replicated your Azure Table data to a MySQL database. This gives you freedom to work with Azure Table 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 Azure Table and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

    Select-AzureTables -Connection $azuretables -Table "NorthwindProducts" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "NorthwindProducts" -Columns $columns -Values $values }
  • If you wish to replicate the Azure Table 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-AzureTables 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')}
