PowerShell Scripting to Replicate Veeva Data to MySQL

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

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

You are ready to connect after specifying the following connection properties:

• Url: The host you see in the URL after you login to your account. For example: https://my-veeva-domain.veevavault.com
• User: The username you use to login to your account.
• Password: The password you use to login to your account.

Collecting Veeva Data

1. Install the module:

   Install-Module VeevaVaultCmdlets

2. Connect to Veeva:

   $veevavault = Connect-Veeva -User $User -Password $Password -Server $Server -Database $Database

3. Retrieve the data from a specific resource:

   $data = Select-Veeva -Connection $veevavault -Table "NorthwindProducts"

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

   $data = Invoke-Veeva -Connection $veevavault -Query 'SELECT * FROM NorthwindProducts WHERE CategoryId = @CategoryId' -Params @{'@CategoryId'='5'}

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

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

Inserting Veeva 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 Veeva 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 Veeva resource (NorthwindProducts) and to exist in the database.

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

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

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

• If you wish to replicate the Veeva 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-Veeva 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')}
