PowerShell Scripting to Replicate Azure DevOps Data to MySQL

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

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

You can connect to your Azure DevOps account by providing the Organization and PersonalAccessToken.

Obtaining a Personal Access Token

To generate one, log in to your Azure DevOps Organization account and navigate to Profile -> Personal Access Tokens -> New Token. The generated token will be displayed.

If you wish to authenticate to Azure DevOps using OAuth refer to the online Help documentation for an authentication guide.

Collecting Azure DevOps Data

1. Install the module:

   Install-Module AzureDevOpsCmdlets

2. Connect to Azure DevOps:

   $azuredevops = Connect-AzureDevOps -AuthScheme $AuthScheme -Organization $Organization -ProjectId $ProjectId -PersonalAccessToken $PersonalAccessToken

3. Retrieve the data from a specific resource:

   $data = Select-AzureDevOps -Connection $azuredevops -Table "Builds"

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

   $data = Invoke-AzureDevOps -Connection $azuredevops -Query 'SELECT * FROM Builds WHERE Reason = @Reason' -Params @{'@Reason'='Manual'}

4. Save a list of the column names from the returned data.

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

Inserting Azure DevOps 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 Azure DevOps 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 Azure DevOps resource (Builds) and to exist in the database.

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

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

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

• If you wish to replicate the Azure DevOps 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-AzureDevOps 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')}
