Google Directory Cmdlets

An easy-to-use set of PowerShell Cmdlets offering real-time access to Google Directory data. The Cmdlets allow users to easily read, write, update, and delete live data - just like working with SQL server.

Write a simple PowerShell script to replicate Google Directory data to a MySQL database.

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

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

Google uses the OAuth authentication standard. You can authorize the data provider to access Google Spreadsheets as an individual user or with a Google Apps Domain service account. See the Getting Started section of the data provider help documentation for an authentication guide.

Collecting Google Directory Data

  1. Install the module:

    Install-Module GoogleDirectoryCmdlets
  2. Connect to Google Directory:

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

    $data = Select-GoogleDirectory -Connection $googledirectory -Table "MyTable"

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

    $data = Invoke-GoogleDirectory -Connection $googledirectory -Query 'SELECT * FROM MyTable WHERE Status = @Status' -Params @{'@Status'='confirmed'}
  4. Save a list of the column names from the returned data.

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

Inserting Google Directory 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 Google Directory 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 Google Directory resource (MyTable) and to exist in the database.

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

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


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

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