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 Id, TotalTax INTO [csv://Transactions.txt] FROM [Transactions] WHERE Code = '051349'

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 Id, TotalTax INTO [csv://Transactions.txt;delimiter=tab] FROM [Transactions] WHERE Code = '051349'

C#

String connectionString = "User=MyUser;Password=MyPassword;";

using (AvalaraConnection connection = new AvalaraConnection(connectionString)) {
  AvalaraCommand cmd = new AvalaraCommand("SELECT Id, TotalTax INTO [csv://Transactions.txt] FROM [Transactions] WHERE Code = '051349' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "User=MyUser;Password=MyPassword;" 

Using connection As New AvalaraConnection(connectionString)
  Dim cmd As New AvalaraCommand("SELECT Id, TotalTax INTO [csv://Transactions.txt] FROM [Transactions] WHERE Code = '051349'", 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 = "User=MyUser;Password=MyPassword;";

using (AvalaraConnection connection = new AvalaraConnection(connectionString)) {
  AvalaraCommand cmd = new AvalaraCommand("SELECT * INTO [Transactions] IN [csv://filename=c:/Transactions.csv;delimiter=tab] FROM [Transactions] WHERE Code = '051349'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "User=MyUser;Password=MyPassword;" 

Using connection As New AvalaraConnection(connectionString)
  Dim cmd As New AvalaraCommand("SELECT * INTO [Transactions] IN [csv://filename=c:/Transactions.csv;delimiter=tab] FROM [Transactions] WHERE Code = '051349'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
