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 No, Contact INTO [csv://Customer.txt] FROM [Customer] WHERE Name = 'CData, Inc.'

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 No, Contact INTO [csv://Customer.txt;delimiter=tab] FROM [Customer] WHERE Name = 'CData, Inc.'

C#

String connectionString = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;";

using (DynamicsNAVConnection connection = new DynamicsNAVConnection(connectionString)) {
  DynamicsNAVCommand cmd = new DynamicsNAVCommand("SELECT No, Contact INTO [csv://Customer.txt] FROM [Customer] WHERE Name = 'CData, Inc.' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;" 

Using connection As New DynamicsNAVConnection(connectionString)
  Dim cmd As New DynamicsNAVCommand("SELECT No, Contact INTO [csv://Customer.txt] FROM [Customer] WHERE Name = 'CData, Inc.'", 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 = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;";

using (DynamicsNAVConnection connection = new DynamicsNAVConnection(connectionString)) {
  DynamicsNAVCommand cmd = new DynamicsNAVCommand("SELECT * INTO [Customer] IN [csv://filename=c:/Customer.csv;delimiter=tab] FROM [Customer] WHERE Name <> 'CData, Inc.'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;" 

Using connection As New DynamicsNAVConnection(connectionString)
  Dim cmd As New DynamicsNAVCommand("SELECT * INTO [Customer] IN [csv://filename=c:/Customer.csv;delimiter=tab] FROM [Customer] WHERE Name <> 'CData, Inc.'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
