PowerShell Scripting to Replicate Dropbox Data to MySQL

Write a simple PowerShell script to replicate Dropbox data to a MySQL database.

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

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

Dropbox uses the OAuth authentication standard. To authenticate using OAuth, you can use the embedded credentials or register an app with Dropbox.

See the Getting Started guide in the CData driver documentation for more information.

Collecting Dropbox Data

  1. Install the module:

    Install-Module DropboxCmdlets
  2. Connect to Dropbox:

    $dropbox = Connect-Dropbox
  3. Retrieve the data from a specific resource:

    $data = Select-Dropbox -Connection $dropbox -Table "Files"

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

    $data = Invoke-Dropbox -Connection $dropbox -Query 'SELECT * FROM Files WHERE Id = @Id' -Params @{'@Id'='1'}
  4. Save a list of the column names from the returned data.

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

Inserting Dropbox 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 Dropbox 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 Dropbox resource (Files) and to exist in the database.

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

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

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