AWS Oracle SE One FireDAC接続TFDConnection[JAPAN] 毛利です。   AWSのRDSでOracle SE Oneデータベースを作成し接続するまでを試しました。 「開発/テスト」用に関しては無料枠があるようです。 インスタンスの仕様とセキュリティ、データベースの設定をします。 全ての設定を終えて数分待てばオラクルDBのインスタンスができます。   C++Builder 10.2 Tokyoを起動しVCLで新規プロジェクトを作成します。 TFDConnectionコンポーネントを使って接続してみます。
Using FireDAC Unidirectional property for fast, low memory selection set processing I often do large Oracle database queries using FireDAC to analyze registration data about our products and customers. Most of the time I am only processing through millions of rows to create a report or chart. One of the FDQuery properties that I forget to set True is the TDFQuery's "Unidirectional" sub-property found under the FetchOptions (TFDFetchOptions) property.  By default Unidirectional is set to false as some developers will want to put the data into a grid or other container and u...

Сколько DBA вам нужно?.. Один из "стандартных" вопросов, который мы слышим: "Зачем нам дополнительные инструменты, кроме тех, что поставляет производитель СУБД, мы и так справимся?" Я расскажу, а дальше вы думайте и решайте сами. В ИТ индустрии, как и в многих других, принято опираться на аналитические обзоры, исследования и мнения аналитиков-экспертов. Компании Gartner и Forrester, надеюсь, представлять не надо. Многие журналисты ведущих зарубежных и отечественных компьютерных изданий пристально следят за аналитичес...
