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 = "MWSAuthToken=myMWSAuthToken;SellerId=mySellerId;Marketplace=United States;Schema=Marketplace;";
using (AmazonMarketplaceConnection connection = new AmazonMarketplaceConnection(connectionString)) {
  int rowsAffected;
  AmazonMarketplaceCommand cmd = new AmazonMarketplaceCommand("DELETE FROM Orders WHERE Id = @myId", connection);
  cmd.Parameters.Add(new AmazonMarketplaceParameter("myId","6"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "MWSAuthToken=myMWSAuthToken;SellerId=mySellerId;Marketplace=United States;Schema=Marketplace;"
Using connection As New AmazonMarketplaceConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New AmazonMarketplaceCommand("DELETE FROM Orders WHERE Id = @myId", connection)
  cmd.Parameters.Add(New AmazonMarketplaceParameter("myId", "6"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
