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 = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;";
using (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(connectionString)) {
  int rowsAffected;
  ReckonAccountsHostedCommand cmd = new ReckonAccountsHostedCommand("DELETE FROM Customers WHERE Id = @myId", connection);
  cmd.Parameters.Add(new ReckonAccountsHostedParameter("myId","10456255-0015501366"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;"
Using connection As New ReckonAccountsHostedConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ReckonAccountsHostedCommand("DELETE FROM Customers WHERE Id = @myId", connection)
  cmd.Parameters.Add(New ReckonAccountsHostedParameter("myId", "10456255-0015501366"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
