PowerShell Scripting to Replicate Jira Data to MySQL

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

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

To connect to JIRA, provide the User and Password. Additionally, provide the Url; for example, https://yoursitename.atlassian.net.

Collecting Jira Data

1. Install the module:

   Install-Module JIRACmdlets

2. Connect to Jira:

   $jira = Connect-JIRA -User $User -Password $Password -Url $Url

3. Retrieve the data from a specific resource:

   $data = Select-JIRA -Connection $jira -Table "Issues"

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

   $data = Invoke-JIRA -Connection $jira -Query 'SELECT * FROM Issues WHERE ReporterDisplayName = @ReporterDisplayName' -Params @{'@ReporterDisplayName'='Bob'}

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

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

Inserting Jira 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 Jira 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 Jira resource (Issues) and to exist in the database.

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

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

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

• If you wish to replicate the Jira 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-JIRA 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')}
