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

PowerShell Scripting to Replicate GitHub Data to MySQL

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

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

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

GitHub uses the OAuth 2 authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started chapter of the CData help documentation for an authentication guide.

Collecting GitHub Data

  1. Install the module:

    Install-Module GitHubCmdlets
  2. Connect to GitHub:

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

    $data = Select-GitHub -Connection $github -Table "Users"

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

    $data = Invoke-GitHub -Connection $github -Query 'SELECT * FROM Users WHERE UserLogin = @UserLogin' -Params @{'@UserLogin'='mojombo'}
  4. Save a list of the column names from the returned data.

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

Inserting GitHub 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 GitHub 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 GitHub 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 GitHub data to a MySQL database. This gives you freedom to work with GitHub 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 GitHub and MySQL in PowerShell, you can pipe command results to perform the replication in a single line:

    Select-GitHub -Connection $github -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 GitHub 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-GitHub 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')}
