SELECT INTO ステートメントを使って、書式付きデータをファイルにエクスポートできます。

SQL クエリを使ったデータのエクスポート

次のクエリは、comma-separated values（CSV）ファイルフォーマットにデータをエクスポートします。

SELECT Key, Etag INTO [csv://Objects.txt] FROM [Objects] WHERE Bucket = 'testBucket'

ファイルURI で他のフォーマットを指定できます。利用可能な区切り文字はタブ、セミコロン、カンマです。デフォルトはカンマです。次の例は、tab-separated values（TSV）にエクスポートします。

SELECT Key, Etag INTO [csv://Objects.txt;delimiter=tab] FROM [Objects] WHERE Bucket = 'testBucket'

C#

String connectionString = "ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;";

using (IBMCloudObjectStorageConnection connection = new IBMCloudObjectStorageConnection(connectionString)) {
  IBMCloudObjectStorageCommand cmd = new IBMCloudObjectStorageCommand("SELECT Key, Etag INTO [csv://Objects.txt] FROM [Objects] WHERE Bucket = 'testBucket' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;" 

Using connection As New IBMCloudObjectStorageConnection(connectionString)
  Dim cmd As New IBMCloudObjectStorageCommand("SELECT Key, Etag INTO [csv://Objects.txt] FROM [Objects] WHERE Bucket = 'testBucket'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using

URI で他のファイルフォーマットを指定できます。以下の例は、tab-separated values（TSV）にエクスポートします。

C#

String connectionString = "ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;";

using (IBMCloudObjectStorageConnection connection = new IBMCloudObjectStorageConnection(connectionString)) {
  IBMCloudObjectStorageCommand cmd = new IBMCloudObjectStorageCommand("SELECT * INTO [Objects] IN [csv://filename=c:/Objects.csv;delimiter=tab] FROM [Objects] WHERE Bucket = 'testBucket'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "ApiKey=myApiKey;CloudObjectStorageCRN=MyInstanceCRN;Region=myRegion;OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;" 

Using connection As New IBMCloudObjectStorageConnection(connectionString)
  Dim cmd As New IBMCloudObjectStorageCommand("SELECT * INTO [Objects] IN [csv://filename=c:/Objects.csv;delimiter=tab] FROM [Objects] WHERE Bucket = 'testBucket'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
