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 = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';";
using (QuickBaseConnection connection = new QuickBaseConnection(connectionString)) {
  int rowsAffected;
  QuickBaseCommand cmd = new QuickBaseCommand("DELETE FROM [CData].[QuickBase].SampleTable_1 WHERE Id = @myId", connection);
  cmd.Parameters.Add(new QuickBaseParameter("myId","6"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';"
Using connection As New QuickBaseConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New QuickBaseCommand("DELETE FROM [CData].[QuickBase].SampleTable_1 WHERE Id = @myId", connection)
  cmd.Parameters.Add(New QuickBaseParameter("myId", "6"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
