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 = "AccessKey=myAccessKey;Account=myAccountName;";
using (AzureTablesConnection connection = new AzureTablesConnection(connectionString)) {
  int rowsAffected;
  AzureTablesCommand cmd = new AzureTablesCommand("DELETE FROM NorthwindProducts WHERE Id = @myId", connection);
  cmd.Parameters.Add(new AzureTablesParameter("myId","1"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "AccessKey=myAccessKey;Account=myAccountName;"
Using connection As New AzureTablesConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New AzureTablesCommand("DELETE FROM NorthwindProducts WHERE Id = @myId", connection)
  cmd.Parameters.Add(New AzureTablesParameter("myId", "1"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
