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=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber";
using (TableauCRMConnection connection = new TableauCRMConnection(connectionString)) {
  int rowsAffected;
  TableauCRMCommand cmd = new TableauCRMCommand("DELETE FROM Dataset_Opportunity WHERE Id = @myId", connection);
  cmd.Parameters.Add(new TableauCRMParameter("myId","25"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyConsumerKey;OAuthClientSecret=MyConsumerSecret;CallbackURL=http://localhost:portNumber"
Using connection As New TableauCRMConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New TableauCRMCommand("DELETE FROM Dataset_Opportunity WHERE Id = @myId", connection)
  cmd.Parameters.Add(New TableauCRMParameter("myId", "25"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
