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

PowerShell Scripting to Replicate Bullhorn CRM Data to MySQL

Write a simple PowerShell script to replicate Bullhorn CRM data to a MySQL database.

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

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

Begin by providing your Bullhorn CRM account credentials in the following:

If you are uncertain about your data center code, codes like CLS2, CLS21, etc. are cluster IDs that are contained in a user's browser URL (address bar) once they are logged in.

Example: indicates that the logged in user is on CLS21.

Authenticating with OAuth

Bullhorn CRM uses the OAuth 2.0 authentication standard. To authenticate using OAuth, create and configure a custom OAuth app. See the Help documentation for more information.

Collecting Bullhorn CRM Data

  1. Install the module:

    Install-Module BullhornCRMCmdlets
  2. Connect to Bullhorn CRM:

    $bullhorncrm = Connect-BullhornCRM -DataCenterCode $DataCenterCode -OAuthClientId $OAuthClientId -OAuthClientSecret $OAuthClientSecret
  3. Retrieve the data from a specific resource:

    $data = Select-BullhornCRM -Connection $bullhorncrm -Table "Candidate"

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

    $data = Invoke-BullhornCRM -Connection $bullhorncrm -Query 'SELECT * FROM Candidate WHERE CandidateName = @CandidateName' -Params @{'@CandidateName'='Jane Doe'}
  4. Save a list of the column names from the returned data.

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

Inserting Bullhorn CRM 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 Bullhorn CRM 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 Bullhorn CRM resource (Candidate) and to exist in the database.

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

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

    Select-BullhornCRM -Connection $bullhorncrm -Table "Candidate" | % { $row = $_ $values = @() $columns | % { $col = $_ $values += $row.$($col) } Add-MySQL -Connection $mysql -Table "Candidate" -Columns $columns -Values $values }
  • If you wish to replicate the Bullhorn CRM 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-BullhornCRM 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')}
