Consult the /tests/*.Tests.ps1 files in the repo for samples of how to use this module to build and deploy.

Each Function should have it's own helping headers... eventually. Currently only the ones that pertain to LocalDB install do.

The basic process is

  • Set up variables to build and deploy
  • Check if VS Build Tools 2017 is Installed and Install if not
  • Install Microsoft.Data.Tools.MSBuild.
  • Build sqlproj file
  • Deploy DACPAC

How To Install Prerequisites


Use either Get-LocalDb2016 or Get-LocalSB2016NuGet to download the LocalDB MSI to a working folder. Then pas MSI when executing Install-LocalDB2016.

All of these functions can be re-run, so if MSI already downloaded or LocalDB already installed then it won't re-try.

This test script includes a step to create a localdb instance to deploy to. Therefore this test script shouldrun without having to set up anything else.

MSBuild Tools

Use Install-VsBuildTools2017 to check if latest MSBuild Tools is installed. If not then function will download and install. Elevated permissions are required!

How To Build SSDT Project

Use Invoke-MsBuildSSDT, passing in the file path to the solution or the project. The path to Data.Tools.MSBuild is also required -

$WWI = Join-Path $PSScriptRoot "wwi-dw-ssdt"
$WWI_SLN = Join-Path $WWI "\WideWorldImportersDW.sqlproj"
$WWI_DAC = Join-Path $WWI "\Microsoft.Data.Tools.Msbuild\lib\net46"
Install-MicrosoftDataToolsMSBuild -WorkingFolder $WWI
Invoke-MsBuildSSDT -DatabaseSolutionFilePath $WWI_SLN -DataToolsFilePath $WWI_DAC 

The above sample set the path to the directory where the sqlproj file is, and also used this as the working directory to download the NuGet package. This means the dlls etc were local to the project.

How Do I Catch Errors From The Build?

Use $lastexitcode when invoking the function Invoke-MSBuildSSDT. This will tell you if the build is successful or not.

$WWI = Join-Path $PSScriptRoot "wwi-dw-ssdt"
$WWI_SLN = Join-Path $WWI "\WideWorldImportersDW.sqlproj"
$WWI_DAC = Join-Path $WWI "\Microsoft.Data.Tools.Msbuild\lib\net46"
Install-MicrosoftDataToolsMSBuild -WorkingFolder $WWI
Invoke-MsBuildSSDT -DatabaseSolutionFilePath $WWI_SLN -DataToolsFilePath $WWI_DAC 
if ($lastexitcode -ne 0){

How To Publish DACPAC

Use Publish-DatabaseDeployment, passsing in the location to the dac dll, the location of the dac dll, the publish file and the dacpac.

As of version 2, there are four new options on the function -

  • -GenerateDeploymentScript - boolean - determines whether Deployment Script is generated.
  • -GenerateDeployMentReport - boolean - determines whether Deployment Report is generated.
  • -ScriptPath - string - folder path where the scriptsa re goingto be created.
  • -ScriptOnly (optional, see How To Only Script Changes Instaead of Deploying? for more info)
$WWI = Join-Path $PSScriptRoot "wwi-dw-ssdt"
$WWI_DAC = Join-Path $WWI "\Microsoft.Data.Tools.Msbuild\lib\net46"
$WWI_DACFX = Join-Path $WWI_DAC "\Microsoft.SqlServer.Dac.dll"
$WWI_DACPAC = Join-Path $WWI "\bin\Debug\WideWorldImportersDW.dacpac"
$WWI_PUB = Join-Path $WWI "\bin\Debug\WideWorldImportersDW.publish.xml"

Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $false -GenerateDeployMentReport $false -ScriptPath $WWI #-getSqlCmdVars

Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $true -GenerateDeployMentReport $false -ScriptPath $WWI #-getSqlCmdVars

Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $false -GenerateDeployMentReport $true -ScriptPath $WWI #-getSqlCmdVars

Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $true -GenerateDeployMentReport $true -ScriptPath $WWI #-getSqlCmdVars

#script only
Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $true -GenerateDeployMentReport $false -ScriptPath $WWI -ScriptOnly #-getSqlCmdVars

Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $false -GenerateDeployMentReport $true -ScriptPath $WWI -ScriptOnly #-getSqlCmdVars

Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME -GenerateDeploymentScript $true -GenerateDeployMentReport $true -ScriptPath $WWI -ScriptOnly #-getSqlCmdVars

Above example again sets the location of the source folder and creates the relative paths.

How To Update SQLCMDVars in a Publish.XML File

If you have SqlCmdVariables that need updating, you can do this by including the 'getSqlCmdVars' switch when executing the Publish-DatabaseDeployment Function. By adding this swtich the function Get-SqlCmdVars is executed. This will attempt to resolve SQLCmd variables via matching powershell variables explicitly defined in the current context. So in the publish.xml file there is a SqlCmdVariable called "DeployTag" with a value of "OldValue". If I want to overwrite this then you will need a PowerShell variable $DeployTag with a new value. if a variable is not found with this value then it will fail if the Switch FailOnMissingVars is included. If there are any missing vars and this switch is not included it will simply write an info message and move on. My post on my blog shows how to Update XML With PowerShell With Elements.

$DeployTag = "NewValue"
Publish-DatabaseDeployment -dacfxPath $WWI_DACFX -dacpac $WWI_DACPAC -publishXml $WWI_PUB -targetConnectionString $svrConnstring -targetDatabaseName $WWI_NAME #-getSqlCmdVars

Update SQLCMDVars if calling Functions from a script

If you are using a script to import the module and execute the deployment using something like VSTS you may need to set the variables with the values to update the SQLCMDVars in the publish xml. The below script sets the parameters to global

param (
\s[parameter(Mandatory = $true)] $WorkingFolder,
 [parameter(Mandatory = $false)] $serverName,
 [parameter(Mandatory=$false)] [string] $sqlAdministratorLogin,
 [parameter(Mandatory=$false)] [String] $sqlAdministratorLoginPassword,
 [parameter(Mandatory=$false)] [String] $connectionString,
 [parameter(Mandatory = $true)] [string] $DatabaseName,
 [parameter(Mandatory = $true)] [string] $DacpacPath,
 [parameter(Mandatory = $true)] [string] $PublishProfile,
 [parameter(Mandatory = $false)] [switch] $getSqlCmdVars,
 [parameter(Mandatory = $true)] [string] $deploytag


Set-Variable -Name "daubbipassword" -Value $deploytag -Scope Global

if ($PSBoundParameters.ContainsKey('connectionString') -eq $false) {
[string] $connectionString = "Server=tcp:$($serverName),1433;Initial Catalog=$($DatabaseName);Persist Security Info=False;User ID=$($sqlAdministratorLogin);Password=$($sqlAdministratorLoginPassword);MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"
try {
 Find-Module -Name "PoshSSDTBuildDeploy"
catch {
 Write-Host "No PoshSSDTBuildDeploy, Installing from PSGallery."
    Install-PackageProvider -Name NuGet -Force -Scope CurrentUser
    Install-Module PoshSSDTBuildDeploy -Force -Scope CurrentUser
finally {
 Write-Host "Importing PoshSSDTBuildDeploy."
 Import-Module PoshSSDTBuildDeploy -Force

$dacFxFolder = Install-MicrosoftDataToolsMSBuild -WorkingFolder $WorkingFolder

$dacFX = Join-Path -Path $dacFxFolder -ChildPath "\Microsoft.SqlServer.Dac.dll"
New-Item -ItemType Directory -Force -Path "$WorkingFolder\deployScripts"

$PublishParams = @{
        dacfxPath                = $dacFX
        dacpac                   = (Resolve-Path $DacpacPath)
        publishXml               = (Resolve-Path $PublishProfile)
        targetConnectionString   = $connectionString
        targetDatabaseName       = $databaseName
        scriptPath               = $WorkingFolder
        GenerateDeploymentReport = $true
        GenerateDeploymentScript = $true
 if ($UserName) {
 $PublishParams.Add("SqlCredential", (New-Object System.Management.Automation.PSCredential ($UserName, $Password)))

if ($PSBoundParameters.ContainsKey('getSqlCmdVars') -eq $true) {
 $PublishParams.Add("GetSqlCmdVars", $true)

  Publish-DatabaseDeployment  @PublishParams

How To Only Script Changes Instead of Deploying?

Use the -ScriptOnly Flag on Publish-DatabaseDeployment. For this to work either -GenerateDeployMentReport or -GenerateDeploymentScript must be set to $true as well as -ScriptPath

Making Use Of GenerateDeployMentReport

If the GenerateDeployMentReport Switch is included, the Publish function will run Get-OperationSummary and Get-OperationTotal functions and output the changes to the console in the form of pscustomobjects. It is now easier to determine what changes are going to be made. IE in the case below we are creating and dropping a few objects -
