¿Es posible crear una base de datos en SQL Server con powershell?

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"

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

I had to add [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') to get this to work but thanks - Cámaras Mortales

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)
}

found out how to do this here http://msdn.microsoft.com/en-us/library/ms162577.aspx

Mi código ahora:

[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"

#Create a new database
$db = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Database -argumentlist $server, "Test_SMO_Database"
$db.Create()

#Reference the database and display the date when it was created. 
$db = $server.Databases["Test_SMO_Database"]
$db.CreateDate

Far too much hassle above if you ask me, this works just fine:

$s = New-PSSession -ComputerName SQLDB -Credential DOMAIN\USER

Invoke-Command -Session $s -ScriptBlock {Invoke-Sqlcmd -ServerInstance SQLDB\INSTANCE -InputFile C:\Users\USER\Downloads\CREATEDB.sql}

Only thing is - you will need to have your DB script already formed and called from thus said location. This is easier for me though due to this being a small part of a bigger script - i dont want to bloat my script if i dont have to and can call SQL scripts from a repo.

I don't think creating the database with the SMO is the right choice as it requires to have SMO installed. Much better is to use only powershell tools to do it.

Consulta este module. It expose most useful commands. One of them is New-SQLDatabase which will be perfect in your situation.

Ejemplo:

New-SQLDatabase -SqlInstance "localost" -DatabaseName "NewDatabase" -Path "D:\pathToFiles\"

Creating new database with powershell

Yes, I am using this in *.ps1 script

$ConnectionString = "Data Source=.\SQLEXPRESS;initial catalog=master;Integrated Security=True;"
$NewDatabaseName = "MyDatabase"

$con = New-Object Data.SqlClient.SqlConnection;
$con.ConnectionString = $ConnectionString;
$con.Open();

# create the database.
$sql = "CREATE DATABASE [$NewDatabaseName] COLLATE SQL_Latin1_General_CP1_CI_AS;"
$cmd = New-Object Data.SqlClient.SqlCommand $sql, $con;
$cmd.ExecuteNonQuery();     
Write-Host "Database $NewDatabaseName is created!";

# close & clear all objects.
$cmd.Dispose();
$con.Close();
$con.Dispose();
