PowerShell Scripting to Replicate Pinterest Data to MySQL

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

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

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

Pinterest authentication is based on the standard OAuth flow. To authenticate, you must initially create an app via the Pinterest developer platform where you can obtain an OAuthClientId, OAuthClientSecret, and CallbackURL.

Set InitiateOAuth to GETANDREFRESH and set OAuthClientId, OAuthClientSecret, and CallbackURL based on the property values for the app you created.

See the Help documentation for other OAuth authentication flows.

Collecting Pinterest Data

  1. Install the module:

    Install-Module PinterestCmdlets
  2. Connect to Pinterest:

    $pinterest = Connect-Pinterest -OAuthClientId $OAuthClientId -OAuthClientSecret $OAuthClientSecret -CallbackURL $CallbackURL
  3. Retrieve the data from a specific resource:

    $data = Select-Pinterest -Connection $pinterest -Table "Users"

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

    $data = Invoke-Pinterest -Connection $pinterest -Query 'SELECT * FROM Users WHERE FirstName = @FirstName' -Params @{'@FirstName'='Jane'}
  4. Save a list of the column names from the returned data.

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

Inserting Pinterest 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 Pinterest 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 Pinterest resource (Users) and to exist in the database.

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

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

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