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://Portals.txt] FROM [Portals] WHERE Id = '123456'

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://Portals.txt;delimiter=tab] FROM [Portals] WHERE Id = '123456'

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;";

using (ZohoProjectsConnection connection = new ZohoProjectsConnection(connectionString)) {
  ZohoProjectsCommand cmd = new ZohoProjectsCommand("SELECT Id, Name INTO [csv://Portals.txt] FROM [Portals] WHERE Id = '123456' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;" 

Using connection As New ZohoProjectsConnection(connectionString)
  Dim cmd As New ZohoProjectsCommand("SELECT Id, Name INTO [csv://Portals.txt] FROM [Portals] WHERE Id = '123456'", 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 = "InitiateOAuth=GETANDREFRESH;";

using (ZohoProjectsConnection connection = new ZohoProjectsConnection(connectionString)) {
  ZohoProjectsCommand cmd = new ZohoProjectsCommand("SELECT * INTO [Portals] IN [csv://filename=c:/Portals.csv;delimiter=tab] FROM [Portals] WHERE Id = '123456'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;" 

Using connection As New ZohoProjectsConnection(connectionString)
  Dim cmd As New ZohoProjectsCommand("SELECT * INTO [Portals] IN [csv://filename=c:/Portals.csv;delimiter=tab] FROM [Portals] WHERE Id = '123456'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
