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;BusinessUnitID=YourBusinessId;"; using (SalesforcePardotConnection connection = new SalesforcePardotConnection(connectionString)) { int rowsAffected; SalesforcePardotCommand cmd = new SalesforcePardotCommand("DELETE FROM Prospects WHERE Id = @myId", connection); cmd.Parameters.Add(new SalesforcePardotParameter("myId","600")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;BusinessUnitID=YourBusinessId;" Using connection As New SalesforcePardotConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New SalesforcePardotCommand("DELETE FROM Prospects WHERE Id = @myId", connection) cmd.Parameters.Add(New SalesforcePardotParameter("myId", "600")) rowsAffected = cmd.ExecuteNonQuery() End Using
