Automate Google Calendar Integration Tasks from PowerShell

The CData Cmdlets for Google Calendar are standard PowerShell cmdlets that make it easy to accomplish data cleansing, normalization, backup, and other integration tasks by enabling real-time and bidirectional access to Google Calendar.

PowerShell Cmdlets or ADO.NET Provider?

The Cmdlets are not only a PowerShell interface to Google Calendar, but also an SQL interface; this tutorial shows how to use both to create, retrieve, update, and delete Google Calendar data. We also show examples of the ADO.NET equivalent, which is possible with the CData ADO.NET Provider for Google Calendars. To access Google Calendar data from other .NET applications, like LINQPad, use the CData ADO.NET Provider for Google Calendars.

Once you have acquired the necessary connection properties, accessing Google Calendar data in PowerShell can be enabled in three steps.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

PowerShell

1. Install the module:

   Install-Module GoogleCalendarCmdlets

2. Connect:

   $googlecalendar = Connect-GoogleCalendar 
   

3. Search for and retrieve data:

   $searchterms = "beach trip"
   $vacationcalendar = Select-GoogleCalendar -Connection $googlecalendar -Table "VacationCalendar" -Where "SearchTerms = `'$SearchTerms`'"
   $vacationcalendar
   

   You can also use the Invoke-GoogleCalendar cmdlet to execute SQL commands:

   $vacationcalendar = Invoke-GoogleCalendar -Connection $googlecalendar -Query 'SELECT * FROM VacationCalendar WHERE SearchTerms = @SearchTerms' -Params @{'@SearchTerms'='beach trip'}
   

ADO.NET

1. Load the provider's assembly:

   [Reflection.Assembly]::LoadFile("C:\Program Files\CData\CData ADO.NET Provider for Google Calendars\lib\System.Data.CData.GoogleCalendar.dll")
    

2. Connect to Google Calendar:

    
   $conn= New-Object System.Data.CData.GoogleCalendar.GoogleCalendarConnection("")
   $conn.Open()
   

3. Instantiate the GoogleCalendarDataAdapter, execute an SQL query, and output the results:

   $sql="SELECT Summary, StartDateTime from VacationCalendar"
   
   $da= New-Object System.Data.CData.GoogleCalendar.GoogleCalendarDataAdapter($sql, $conn)
   $dt= New-Object System.Data.DataTable
   $da.Fill($dt)
   
   $dt.Rows | foreach {
   	Write-Host $_.summary $_.startdatetime
   }
    

Update Google Calendar Data

PowerShell

Update-GoogleCalendar -Connection $GoogleCalendar -Columns @('Summary','StartDateTime') -Values @('MySummary', 'MyStartDateTime') -Table VacationCalendar -Id "MyId"

ADO.NET

$cmd = New-Object System.Data.CData.GoogleCalendar.GoogleCalendarCommand("UPDATE VacationCalendar SET SearchTerms='beach trip' WHERE Id = @myId", $conn)
$cmd.Parameters.Add((New-Object System.Data.CData.GoogleCalendar.GoogleCalendarParameter("@myId","10456255-0015501366")))
$cmd.ExecuteNonQuery()

Insert Google Calendar Data

PowerShell

Add-GoogleCalendar -Connection $GoogleCalendar -Table VacationCalendar -Columns @("Summary", "StartDateTime") -Values @("MySummary", "MyStartDateTime") 

ADO.NET

$cmd = New-Object System.Data.CData.GoogleCalendar.GoogleCalendarCommand("INSERT INTO VacationCalendar (SearchTerms) VALUES (@mySearchTerms)", $conn)
$cmd.Parameters.Add((New-Object System.Data.CData.GoogleCalendar.GoogleCalendarParameter("@mySearchTerms","beach trip")))
$cmd.ExecuteNonQuery()

Delete Google Calendar Data

PowerShell

Remove-GoogleCalendar -Connection $GoogleCalendar -Table "VacationCalendar" -Id "MyId"

ADO.NET

$cmd = New-Object System.Data.CData.GoogleCalendar.GoogleCalendarCommand("DELETE FROM VacationCalendar WHERE Id=@myId", $conn)
$cmd.Parameters.Add((New-Object System.Data.CData.GoogleCalendar.GoogleCalendarParameter("@myId","001d000000YBRseAAH")))
$cmd.ExecuteNonQuery()
