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 ShipName, ShipCity INTO [csv://Orders.txt] FROM [Orders] WHERE ShipCountry = 'USA'

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 ShipName, ShipCity INTO [csv://Orders.txt;delimiter=tab] FROM [Orders] WHERE ShipCountry = 'USA'

C#

String connectionString = "Data Source=C:\\MyData;";

using (xBaseConnection connection = new xBaseConnection(connectionString)) {
  xBaseCommand cmd = new xBaseCommand("SELECT ShipName, ShipCity INTO [csv://Orders.txt] FROM [Orders] WHERE ShipCountry = 'USA' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Data Source=C:\\MyData;" 

Using connection As New xBaseConnection(connectionString)
  Dim cmd As New xBaseCommand("SELECT ShipName, ShipCity INTO [csv://Orders.txt] FROM [Orders] WHERE ShipCountry = 'USA'", 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 = "Data Source=C:\\MyData;";

using (xBaseConnection connection = new xBaseConnection(connectionString)) {
  xBaseCommand cmd = new xBaseCommand("SELECT * INTO [Orders] IN [csv://filename=c:/Orders.csv;delimiter=tab] FROM [Orders] WHERE ShipCountry = 'USA'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Data Source=C:\\MyData;" 

Using connection As New xBaseConnection(connectionString)
  Dim cmd As New xBaseCommand("SELECT * INTO [Orders] IN [csv://filename=c:/Orders.csv;delimiter=tab] FROM [Orders] WHERE ShipCountry = 'USA'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
