DELETE ステートメント

テーブルから情報を削除するには、DELETE ステートメントを使用します。

DELETE 構文

DELETE ステートメントには、次の例に示すように、FROM 句のテーブル名とWHERE 句の行の主キーが必要です。

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

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

次の例に示すように、ExecuteNonQuery メソッドを使って、データ操作コマンドを実行し影響を受ける行数を取得できます。

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'";
using (AsanaConnection connection = new AsanaConnection(connectionString)) {
  int rowsAffected;
  AsanaCommand cmd = new AsanaCommand("DELETE FROM projects WHERE Id = @myId", connection);
  cmd.Parameters.Add(new AsanaParameter("myId","1128092964672848"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CallbackURL='http://localhost:33333'"
Using connection As New AsanaConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New AsanaCommand("DELETE FROM projects WHERE Id = @myId", connection)
  cmd.Parameters.Add(New AsanaParameter("myId", "1128092964672848"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
