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;OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;";
using (AzureADConnection connection = new AzureADConnection(connectionString)) {
  int rowsAffected;
  AzureADCommand cmd = new AzureADCommand("DELETE FROM DirectoryRoles WHERE Id = @myId", connection);
  cmd.Parameters.Add(new AzureADParameter("myId","Jq74mCczmFXk1tC10GB"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;"
Using connection As New AzureADConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New AzureADCommand("DELETE FROM DirectoryRoles WHERE Id = @myId", connection)
  cmd.Parameters.Add(New AzureADParameter("myId", "Jq74mCczmFXk1tC10GB"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
