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, Name INTO [csv://Accounts.txt] FROM [Accounts] WHERE Type = 'Bank'

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, Name INTO [csv://Accounts.txt;delimiter=tab] FROM [Accounts] WHERE Type = 'Bank'

C#

String connectionString = " If using an online instance: OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CompanyFileId=yourCompanyFileId;CallbackURL=http://localhost:33333;User=companyFileUser;Password=companyFilePassword; If using an on premise instance: InitiateOAuth=OFF;URL=http://localhost:8080/accountright;CompanyFileId=327eed10-9615-4e5e-bd9e-ae2cc00e2c70;User=companyFileUser;Password=companyFilePassword;";

using (MYOBConnection connection = new MYOBConnection(connectionString)) {
  MYOBCommand cmd = new MYOBCommand("SELECT Id, Name INTO [csv://Accounts.txt] FROM [Accounts] WHERE Type = 'Bank' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = " If using an online instance: OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CompanyFileId=yourCompanyFileId;CallbackURL=http://localhost:33333;User=companyFileUser;Password=companyFilePassword; If using an on premise instance: InitiateOAuth=OFF;URL=http://localhost:8080/accountright;CompanyFileId=327eed10-9615-4e5e-bd9e-ae2cc00e2c70;User=companyFileUser;Password=companyFilePassword;" 

Using connection As New MYOBConnection(connectionString)
  Dim cmd As New MYOBCommand("SELECT Id, Name INTO [csv://Accounts.txt] FROM [Accounts] WHERE Type = 'Bank'", 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#
