Come automatizzare la generazione di script tramite SMO in SQL Server?

Question

Vorrei automatizzare la generazione di script (in SSMS -> Attività -> Genera script) in SSMS 2008. Ho letto che SQL Server 2008 non supporta la Pubblicazione guidata database (incluso SQLPUBWIZ SCRIPT) ma questa automazione può essere eseguita usando SMO in SQL Server 2008. Non ho idea di SMO e di come farlo usando SMO, quindi potresti darmi qualche consiglio (risorse ecc.) come iniziare?

Answer 1

La chiave dello scripting SMO è la classe Scripter. Tutti gli altri strumenti (come SSMS) usano questa classe per generare script di creazione di oggetti. V'è un esempio di utilizzo su MSDN:

{ 
    //Connect to the local, default instance of SQL Server. 
    Server srv = new Server(); 

    //Reference the AdventureWorks2008R2 database. 
    Database db = srv.Databases["AdventureWorks2008R2"]; 

    //Define a Scripter object and set the required scripting options. 
    Scripter scrp = new Scripter(srv); 
    scrp.Options.ScriptDrops = false; 
    scrp.Options.WithDependencies = true; 

    //Iterate through the tables in database and script each one. Display the script. 
    //Note that the StringCollection type needs the System.Collections.Specialized namespace to be included. 
    Microsoft.SqlServer.Management.Sdk.Sfc.Urn[] smoObjects = new Microsoft.SqlServer.Management.Sdk.Sfc.Urn[1] ; 
    foreach (Table tb in db.Tables) { 
     smoObjects[0] = tb.Urn; 
     if (tb.IsSystemObject == false) { 
     System.Collections.Specialized.StringCollection sc; 
     sc = scrp.Script(smoObjects); 
     foreach (string st in sc) { 
      Console.WriteLine(st); 
     } 
     } 
    } 
}

C'è alcuni modi di scripting tutti gli oggetti nel database, ma uno dei più facili è a voi la classe tranfer SMO. Ecco qualche codice PowerShell allo script fuori tutti gli oggetti:

add-type -AssemblyName "Microsoft.SqlServer.ConnectionInfo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" 
add-type -AssemblyName "Microsoft.SqlServer.Smo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" 
add-type -AssemblyName "Microsoft.SqlServer.SMOExtended, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" 

$sourceSrv = "$env:computername\sql2k8" 
$sourceDb = "Northwind" 

$server = new-object ("Microsoft.SqlServer.Management.Smo.Server") $sourceSrv 
$db = $server.Databases[$sourceDb] 

$transfer = new-object ("Microsoft.SqlServer.Management.Smo.Transfer") $db 
$transfer.CopyAllObjects = $true 
$transfer.DropDestinationObjectsFirst = $true 
$transfer.CopySchema = $true 
$transfer.Options.IncludeIfNotExists = $true 

$transfer.ScriptTransfer()

Anche se la questione è stata accuratamente risposto, ho lottato per un paio di giorni per mettere insieme uno script che script fuori tutti gli oggetti che mi interessava su un server di database. Ecco il mio codice nel caso in cui a un certo punto sia utile a qualcun altro.
