You can use the SELECT INTO statement to export formatted data to a file.

Data Export with an SQL Query

The following query exports data into a file formatted in comma-separated values (CSV):

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

You can specify other formats in the file URI. The possible delimiters are tab, semicolon, and comma with the default being a comma. The following example exports tab-separated values:

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

You can specify other file formats in the URI. The following example exports tab-separated values:

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
