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 UserKey, Email INTO [csv://Users.txt] FROM [Users] WHERE UserKey = 'agxzfm1haWxmb29nYWVyLAsSDE9yZ2FuaXphdGlvbiIJY2RhdGEuY29tDAsSBFVzZXIYgICs35ruuwkM'

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 UserKey, Email INTO [csv://Users.txt;delimiter=tab] FROM [Users] WHERE UserKey = 'agxzfm1haWxmb29nYWVyLAsSDE9yZ2FuaXphdGlvbiIJY2RhdGEuY29tDAsSBFVzZXIYgICs35ruuwkM'

C#

String connectionString = "ApiKey=8c84j9b4j54762ce809ej6a782d776j3;";

using (StreakConnection connection = new StreakConnection(connectionString)) {
  StreakCommand cmd = new StreakCommand("SELECT UserKey, Email INTO [csv://Users.txt] FROM [Users] WHERE UserKey = 'agxzfm1haWxmb29nYWVyLAsSDE9yZ2FuaXphdGlvbiIJY2RhdGEuY29tDAsSBFVzZXIYgICs35ruuwkM' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "ApiKey=8c84j9b4j54762ce809ej6a782d776j3;" 

Using connection As New StreakConnection(connectionString)
  Dim cmd As New StreakCommand("SELECT UserKey, Email INTO [csv://Users.txt] FROM [Users] WHERE UserKey = 'agxzfm1haWxmb29nYWVyLAsSDE9yZ2FuaXphdGlvbiIJY2RhdGEuY29tDAsSBFVzZXIYgICs35ruuwkM'", 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=8c84j9b4j54762ce809ej6a782d776j3;";

using (StreakConnection connection = new StreakConnection(connectionString)) {
  StreakCommand cmd = new StreakCommand("SELECT * INTO [Users] IN [csv://filename=c:/Users.csv;delimiter=tab] FROM [Users] WHERE UserKey = 'agxzfm1haWxmb29nYWVyLAsSDE9yZ2FuaXphdGlvbiIJY2RhdGEuY29tDAsSBFVzZXIYgICs35ruuwkM'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "ApiKey=8c84j9b4j54762ce809ej6a782d776j3;" 

Using connection As New StreakConnection(connectionString)
  Dim cmd As New StreakCommand("SELECT * INTO [Users] IN [csv://filename=c:/Users.csv;delimiter=tab] FROM [Users] WHERE UserKey = 'agxzfm1haWxmb29nYWVyLAsSDE9yZ2FuaXphdGlvbiIJY2RhdGEuY29tDAsSBFVzZXIYgICs35ruuwkM'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
