指定したパッケージがSQL Serverのインスタンスに存在するかどうかを示すブール値を返します。

public:
 bool ExistsOnSqlServer(System::String ^ packagePath, System::String ^ serverName, System::String ^ serverUserName, System::String ^ serverPassword);

public bool ExistsOnSqlServer (string packagePath, string serverName, string serverUserName, string serverPassword);

member this.ExistsOnSqlServer : string * string * string * string -> bool

Public Function ExistsOnSqlServer (packagePath As String, serverName As String, serverUserName As String, serverPassword As String) As Boolean

パラメーター

packagePath

String

検索対象のパッケージです。

serverName

String

パッケージを検索する SQL Server のインスタンスの名前です。

serverUserName

String

SQL Server のインスタンスに対して認証するユーザー名です。

serverPassword

例

次のコード例では、SQL Server フォルダーを作成し、そのフォルダーが存在することを確認してから、そのフォルダーを削除し、その存在を再確認します。 また、パッケージを保存し、ExistsOnSqlServer メソッドを使用して、そのパッケージが保存されたことも確認します。

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  

サンプル出力:

Folder exists? True

Package exists? True

Folder exists? False
