PowerShell Using **DacServices** With SQLCMD Variables To Deploy A DACPAC

In PowerShell I'm using Microsoft.SqlServer.Dac.DacServices and Microsoft.SqlServer.Dac.DacDeployOptions to deploy/update a database DACPAC. The problem I am having is finding where to set the SQLCMD Variables the package requires.

Abbreviated Sample

# Create a DacServices object, which needs a connection string 
$dacsvcs = New-Object Microsoft.SqlServer.Dac.DacServices "server=$sqlserver"

# Load dacpac from file
$dp = [Microsoft.SqlServer.Dac.DacPackage]::Load($dacpac) 

# Deploy options
$deployOptions = New-Object Microsoft.SqlServer.Dac.DacDeployOptions
$deployOptions.IncludeCompositeObjects = $true

I know I can input these just fine with SqlPackage.exe, and maybe that's what I should do. But no where in the documentation or web grok can I find an example of DacServices usage with SQLCMD variables as an option--SQLCMD variables as required parameters for my project's DACPAC.

I have another code snippet to share in relation to this, a method of processing multiple variables from a Powershell script argument;

param(
[hashtable] $SqlCmdVar
)

$deployOptions = New-Object Microsoft.SqlServer.Dac.DacDeployOptions

# Process the Sql Command Variables
#
if ($SqlCmdVar -ne $null)
{
    foreach($key in $SqlCmdVar.keys)
    {
        Write-Verbose -Message "Adding Sql Command Variable ""$key""..."

        $deployOptions.SqlCommandVariableValues.Add($key,$SqlCmdVar[$key])
    }
}

You would call the script like this;

myscript.ps1 -SqlCmdVar @{ variable1 = "my first value"; variable2 = "my second value"; variableetc = "more values"}

You should set options in the $deployOptions.SqlCommandVariableValues property. This is an updateabase Dictionary - you can't assign a new dictionary but you can update the key/value pairs inside it. For example to set a variable "MyDatabaseRef" to "Database123" use 

$deployOptions.SqlCommandVariableValues.Add("MyDatabaseRef", "Database123");

The API reference is here.
