PowerShell Scripting to Replicate PowerShell Scripts to MySQL

Write a simple PowerShell script to replicate PowerShell scripts to a MySQL database.

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

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

The ScriptLocation, under the Data section, must be set to a valid script location.

Collecting PowerShell Scripts

  1. Install the module:

    Install-Module PowerShellCmdlets
  2. Connect to PowerShell:

    $powershell = Connect-PowerShell -ScriptLocation $ScriptLocation -ExecuteQuery $ExecuteQuery
  3. Retrieve the data from a specific resource:

    $data = Select-PowerShell -Connection $powershell -Table "Process"

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

    $data = Invoke-PowerShell -Connection $powershell -Query 'SELECT * FROM Process WHERE ProcessName = @ProcessName' -Params @{'@ProcessName'='RemoteConnectorService'}
  4. Save a list of the column names from the returned data.

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

Inserting PowerShell Scripts 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 PowerShell scripts, 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 PowerShell resource (Process) and to exist in the database.

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

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

    Select-PowerShell -Connection $powershell -Table "Process" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Process" -Columns $columns -Values $values }
  • If you wish to replicate the PowerShell scripts 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-PowerShell 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')}
