Exemples

L’exemple de code suivant crée un dossier SQL Server, vérifie qu’il existe, puis supprime le dossier et revérifie son existence. Il enregistre également un package et vérifie que le package a été enregistré à l’aide de la ExistsOnSqlServer méthode.

static void Main(string[] args)  
        {  
            // The variable pkg points to the location  
            // of the ExecuteProcess package sample   
            // that is installed with the SSIS samples.  
            string p = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";  

            Application app = new Application();  

            // Create a folder on SQL Server in the msdb database.  
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", null, null);  

            // Verify that the folder exists by using ExistsOnSqlServer method.  
            Boolean folderExists = app.FolderExistsOnSqlServer("myNewFolder", "yourserver", null, null);  
            Console.WriteLine("Folder exists? {0}", folderExists);  

            // Load a package and save it.  
            Package pkg = app.LoadPackage(p, null);  
            app.SaveToSqlServerAs(pkg, null, "newPkg", "yourserver", null, null);  

            // Verify that the package was saved.  
            Boolean packageExists = app.ExistsOnSqlServer("newPkg", "yourserver", null, null);  
            Console.WriteLine("Package exists? {0}", packageExists);  

            //Remove the folder.  
            app.RemoveFolderFromSqlServer("myNewFolder", "yourserver", null, null);  

            // Verify that the folder was removed by using the ExistsOnSqlServer method.  
            folderExists = app.FolderExistsOnSqlServer("myNewFolder", "yourserver", null, null);  
            Console.WriteLine("Folder exists? {0}", folderExists);  
        }  

Sub Main(ByVal args() As String)  
            ' The variable pkg points to the location  
            ' of the ExecuteProcess package sample   
            ' that is installed with the SSIS samples.  
            Dim p As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx"   

            Dim app As Application =  New Application()   

            ' Create a folder on SQL Server in the msdb database.  
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the folder exists by using ExistsOnSqlServer method.  
            Dim folderExists As Boolean =  app.FolderExistsOnSqlServer("myNewFolder","yourserver",Nothing,Nothing)   
            Console.WriteLine("Folder exists? {0}", folderExists)  

            ' Load a package and save it.  
            Dim pkg As Package =  app.LoadPackage(p,Nothing)   
            app.SaveToSqlServerAs(pkg, Nothing, "newPkg", "yourserver", Nothing, Nothing)  

            ' Verify that the package was saved.  
            Dim packageExists As Boolean =  app.ExistsOnSqlServer("newPkg","yourserver",Nothing,Nothing)   
            Console.WriteLine("Package exists? {0}", packageExists)  

            'Remove the folder.  
            app.RemoveFolderFromSqlServer("myNewFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the folder was removed by using the ExistsOnSqlServer method.  
            folderExists = app.FolderExistsOnSqlServer("myNewFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("Folder exists? {0}", folderExists)  
End Sub

Exemple de sortie :

Folder exists? True

Package exists? True

Folder exists? False
