定義

名前空間:

Microsoft.SqlServer.Dts.Runtime

アセンブリ:

Microsoft.SqlServer.ManagedDTS.dll

指定したフォルダーが既にSQL Serverのインスタンスに存在するかどうかを示すブール型 (Boolean) の値を返します。

public:
 bool FolderExistsOnSqlServer(System::String ^ strFolderName, System::String ^ strServerName, System::String ^ strServerUserName, System::String ^ strServerPassword);

public bool FolderExistsOnSqlServer (string strFolderName, string strServerName, string strServerUserName, string strServerPassword);

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

Public Function FolderExistsOnSqlServer (strFolderName As String, strServerName As String, strServerUserName As String, strServerPassword As String) As Boolean

パラメーター

strFolderName

String

検索対象のフォルダーです。

strServerName

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。

strServerUserName

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。

strServerPassword

String

指定した strServerUserName のパスワードです。

戻り値

Boolean

SQL Serverの指定したインスタンスにフォルダーが存在する場合は true、フォルダーが存在しない場合は false。

例

次のコード例では、SQL Serverにフォルダーを作成し、名前を変更してから削除します。 また、FolderExistsOnSqlServer を使用して、フォルダーの存在の確認も行います。

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 pkg = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";  

            Application app = new Application();  
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", null, null);  

            // Verify that the folder was created.  
            Boolean ssFolder = app.FolderExistsOnSqlServer("\\myNewFolder", "yourserver", null, null);  
            Console.WriteLine("myNewFolderExists? " + ssFolder);  

            // Rename the myNewFolder to myRenamedFolder.   
            app.RenameFolderOnSqlServer("\\", "myNewFolder", "myRenamedFolder", "yourserver", null, null);  

            // Verify that the old folder does not exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myNewFolder", "yourserver", null, null);  
            Console.WriteLine("myNewFolderExists has been renamed but still exists? " + ssFolder);  

            // Verify that a folder with the new name does exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", null, null);  
            Console.WriteLine("myRenamedFolder now exists? " + ssFolder);  

            // Delete the folder.  
            app.RemoveFolderFromSqlServer("\\myRenamedFolder", "yourserver", null, null);  

            // Verify that the folder was removed.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", null, null);  
            Console.WriteLine("myRenamedFolder still exists? " + ssFolder);  
        }  

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 pkg 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()   
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the folder was created.  
            Dim ssFolder As Boolean =  app.FolderExistsOnSqlServer("\\myNewFolder","yourserver",Nothing,Nothing)   
            Console.WriteLine("myNewFolderExists? " + ssFolder)  

            ' Rename the myNewFolder to myRenamedFolder.   
            app.RenameFolderOnSqlServer("\\", "myNewFolder", "myRenamedFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the old folder does not exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myNewFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("myNewFolderExists has been renamed but still exists? " + ssFolder)  

            ' Verify that a folder with the new name does exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("myRenamedFolder now exists? " + ssFolder)  

            ' Delete the folder.  
            app.RemoveFolderFromSqlServer("\\myRenamedFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the folder was removed.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("myRenamedFolder still exists? " + ssFolder)  
End Sub  

サンプル出力:

myNewFolderExists? True

myNewFolderExists has been renamed but still exists? False

myRenamedFolder now exists? True

myRenamedFolder still exists? False
