Is it possible to create a Database in SQL Server with powershell?

Question

I am trying to create a empty database in SQL server using powershell and SMO but cannot seem to find a way of doing it. Is this possible?

Connection script for sql server:

[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null

$serverName = "localhost"

$server = new-object ('Microsoft.SqlServer.Management.Smo.Server') $serverName

$server.ConnectionContext.LoginSecure=$false;
$credential = Get-Credential
$loginName = $credential.UserName -replace("\\","")
$server.ConnectionContext.set_Login($loginName);
$server.ConnectionContext.set_SecurePassword($credential.Password)
$server.ConnectionContext.ApplicationName="SQLDeploymentScript"

Answer 1

SMO certainly supports a database create method - the linked MSDN page includes a powershell example:

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database($srv, "Test_SMO_Database")
$db.Create()
Write-Host $db.CreateDate

Answer 2

In my go.bat script, that sets up the environment for the service, I check if the db exists, and if it doesn't, I create one.

[reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
$server = new-object ("Microsoft.SqlServer.Management.Smo.Server") .

$dbExists = $FALSE
foreach ($db in $server.databases) {
  if ($db.name -eq "Db") {
    Write-Host "Db already exists."
    $dbExists = $TRUE
  }
}

if ($dbExists -eq $FALSE) {
  $db = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Database -argumentlist $server, "Db"
  $db.Create()

  $user = "NT AUTHORITY\NETWORK SERVICE"
  $usr = New-Object -TypeName Microsoft.SqlServer.Management.Smo.User -argumentlist $db, $user
  $usr.Login = $user
  $usr.Create()

  $role = $db.Roles["db_datareader"]
  $role.AddMember($user)
}
