To delete information from a table, use DELETE statements.

DELETE Syntax

The DELETE statement requires the table name in the FROM clause and the row's primary key in the WHERE clause, as shown in the following example:

<delete_statement> ::= DELETE FROM <table_name> WHERE { Id = <expression> } [ { AND | OR } ... ]

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the number of affected rows, as shown in the following example:

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;ContentOwnerId=MyContentOwnerId;ChannelId=ChannelId;";
using (YouTubeAnalyticsConnection connection = new YouTubeAnalyticsConnection(connectionString)) {
  int rowsAffected;
  YouTubeAnalyticsCommand cmd = new YouTubeAnalyticsCommand("DELETE FROM Groups WHERE Id = @myId", connection);
  cmd.Parameters.Add(new YouTubeAnalyticsParameter("myId","S"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;ContentOwnerId=MyContentOwnerId;ChannelId=ChannelId;"
Using connection As New YouTubeAnalyticsConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New YouTubeAnalyticsCommand("DELETE FROM Groups WHERE Id = @myId", connection)
  cmd.Parameters.Add(New YouTubeAnalyticsParameter("myId", "S"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
