ノーコードでクラウド上のデータとの連携を実現。
詳細はこちら →Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Greenplum, you gain access to live Greenplum データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Greenplum データ. This article will walk through connecting to Greenplum and creating a simple VCL application with the Form Designer.
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Greenplum に接続するには、Server、Port (デフォルトポートは5432)、およびDatabase 接続プロパティを設定して、サーバーへの認証に使用するUser とPassword を設定します。Database プロパティが指定されていない場合、CData 製品はユーザーのデフォルトデータベース(ユーザーと同じ名前になります)に接続します。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Greenplum データ.
Follow the procedure below to start executing queries to Greenplum データ from a simple VCL application that displays the results of a query in a grid.
Drop a TFDConnection component onto the form and set the following properties:
Drop a TFDQuery component onto the form and set the properties below:
SQL: Click the button in the SQL property and enter a query. For example:
SELECT Freight, ShipName FROM Orders WHERE ShipCountry = USA
Drop a TDataSource component onto the form and set the following property:
Drop a TDBGrid control onto the form and set the following property:
You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
