SQL Azure and Powershell for DACPAC deploy

Question

I am deploying a dacpac built on visual studio 2012 to SQL Azure using powershell and running into issues which I think could be related to some version incompatiblity. The publish works fine when I do it from visual studio but throws an exception when I do it using powershell.

Here is what I am doing in Powershell

[System.Reflection.Assembly]::Load("Microsoft.SqlServer.Management.Sdk.Sfc, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") | out-null
[System.Reflection.Assembly]::Load("Microsoft.SqlServer.Smo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") | out-null
[System.Reflection.Assembly]::Load("Microsoft.SqlServer.ConnectionInfo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") | out-null
[System.Reflection.Assembly]::Load("Microsoft.SqlServer.Management.Dac, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91") | out-null

Trap 
{  
  PrintException($_.Exception);
  $fileStream.Close()  
  return;  
}

$sqlServerFullName = $sqlServerName + ".database.windows.net"
$serverConnection = New-Object Microsoft.SqlServer.Management.Common.ServerConnection($sqlServerFullName, $adminLogin, $admingPwd)
$serverconnection.Connect()

$dacstore = New-Object Microsoft.SqlServer.Management.Dac.DacStore($serverConnection)
$fileStream = [System.IO.File]::Open($dacpacPath,[System.IO.FileMode]::OpenOrCreate)

Write-Host "Reading contents from $dacpacPath..."
$dacType = [Microsoft.SqlServer.Management.Dac.DacType]::Load($fileStream)

The last line in the code above is what is crashing with the following error (inner exception value) and not proceeding further

The stream cannot be read to construct the DacType.

There is an error in XML document (2, 2).

<DacType xmlns='http://schemas.microsoft.com/sqlserver/dac/Serialization/2012/0
2'> was not expected.

Here is the $PSVersionTable from powershell ISE that I am using

Name                           Value

SerializationVersion           1.1.0.1     

Wondering what could cause this issue when I deploy using Powershell when it works fine when I deploy it using visual studio 2012

P.S. - The powershell deploy works fine using the same script with a dacpac file that I found on the internet which was apparently targeted for a SQL 2005 version

Answer 1

If you installed latest SSDT 2015 (https://msdn.microsoft.com/en-us/mt186501). I highly recommended it because it has a lot of useful options for the Publish profile, which can be generated using Visual Studio.

You can use the following to publish your file to Azure using Powershell

$sqlpackage = "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\120\sqlpackage.exe"

$dbserver = "<Azure DB Location>"  
$database = "<name of DB on Server>"

# UNC Paths

$dbProfile = "<Path to your Publish Profile>"
$mydacpac = "<location of the dacpac>" 

# Publish Command

& $sqlpackage /Action:Publish /tsn:$dbServer /tdn:$database /sf:$mydacpac/pr:$dbProfile /variables:myVariable=1

PS : & works like Invoke-Expression mentioned by Pradebban

Answer 2

Try publishing with sqlpackage.exe and Publish.xml

Invoke-Expression = "C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe /Action:Publish /Sourcefile:<.dacpac file_path> /pr:'<Publish.xml>'"
