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 DslAddressDatabase, Type INTO [csv://Tables.txt] FROM [Tables] WHERE Name = 'FactProductInventory'

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 DslAddressDatabase, Type INTO [csv://Tables.txt;delimiter=tab] FROM [Tables] WHERE Name = 'FactProductInventory'

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;";

using (AzureDataCatalogConnection connection = new AzureDataCatalogConnection(connectionString)) {
  AzureDataCatalogCommand cmd = new AzureDataCatalogCommand("SELECT DslAddressDatabase, Type INTO [csv://Tables.txt] FROM [Tables] WHERE Name = 'FactProductInventory' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;" 

Using connection As New AzureDataCatalogConnection(connectionString)
  Dim cmd As New AzureDataCatalogCommand("SELECT DslAddressDatabase, Type INTO [csv://Tables.txt] FROM [Tables] WHERE Name = 'FactProductInventory'", 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 = "InitiateOAuth=GETANDREFRESH;";

using (AzureDataCatalogConnection connection = new AzureDataCatalogConnection(connectionString)) {
  AzureDataCatalogCommand cmd = new AzureDataCatalogCommand("SELECT * INTO [Tables] IN [csv://filename=c:/Tables.csv;delimiter=tab] FROM [Tables] WHERE Name = 'FactProductInventory'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;" 

Using connection As New AzureDataCatalogConnection(connectionString)
  Dim cmd As New AzureDataCatalogCommand("SELECT * INTO [Tables] IN [csv://filename=c:/Tables.csv;delimiter=tab] FROM [Tables] WHERE Name = 'FactProductInventory'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
