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 UUID, Name INTO [csv://Clients.txt] FROM [Clients] WHERE Name = 'Bob'

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 UUID, Name INTO [csv://Clients.txt;delimiter=tab] FROM [Clients] WHERE Name = 'Bob'

C#

String connectionString = "OAuthClientID=myClientID;OAuthClientSecret=myClientSecret";

using (XeroWorkflowMaxConnection connection = new XeroWorkflowMaxConnection(connectionString)) {
  XeroWorkflowMaxCommand cmd = new XeroWorkflowMaxCommand("SELECT UUID, Name INTO [csv://Clients.txt] FROM [Clients] WHERE Name = 'Bob' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "OAuthClientID=myClientID;OAuthClientSecret=myClientSecret" 

Using connection As New XeroWorkflowMaxConnection(connectionString)
  Dim cmd As New XeroWorkflowMaxCommand("SELECT UUID, Name INTO [csv://Clients.txt] FROM [Clients] WHERE Name = 'Bob'", 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 = "OAuthClientID=myClientID;OAuthClientSecret=myClientSecret";

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

VB.NET

Dim connectionString As [String] = "OAuthClientID=myClientID;OAuthClientSecret=myClientSecret" 

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