Viewing MariaDB データ in RAD Studio Data Explorer

How to view MariaDB データ in RAD Studio Data Explorer using the CData ODBC Driver for MariaDB.

最終更新日：2023-06-12

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for MariaDB, you gain access to live MariaDB データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update MariaDB データ. This article will walk through connecting to MariaDB using the Data Explorer.

Configure a Connection to MariaDB

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.

接続には、MariaDB サーバーのServer およびPort プロパティを設定します。IntegratedSecurity をFALSE に設定する場合、User およびPassword プロパティが必要になります。Database は設定すればデータベースの指定が可能です。設定しない場合には全データベースが使えます。

Connecting to MariaDB データ Using Data Explorer

You can create a simple application for displaying MariaDB データ by utilizing the CData FireDAC Components for MariaDB and a new VCL Forms Application:

Open the Data Explorer in RAD Studio and expand FireDAC.
Right-click the ODBC Data Source node in the Data Explorer.
Click Add New Connection.
Enter a name for the connection.
In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for MariaDB.
Back in the Data Explorer, expand the tables for the connection.
Create a new VCL Forms application and drag a table (for example: Orders) onto the form.
Select the OrdersTable object on the form and set the Active property to true.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).
Arrange the TStringGrid on the form and run the application to see the Orders data.
