In this article, we will show you how to use MyDAC 9.0.2 Professional to create a simple MySQL database application in Delphi. We will use the sample database \"sakila\" that comes with MySQL server installation. You can also download it from https://dev.mysql.com/doc/index-other.html.

Step 1: Install MyDAC 9.0.2 Professional

To install MyDAC 9.0.2 Professional, you need to have RAD Studio 11 Alexandria installed on your computer. You can download a free trial version of RAD Studio from https://www.embarcadero.com/products/rad-studio/start-for-free.

After downloading the MyDAC installer from https://www.devart.com/mydac/, run it and follow the instructions on the screen. You can choose to install MyDAC for Delphi, C++Builder, or both. You can also select the components and demos that you want to install.

After the installation is complete, you can find the MyDAC components on the \"Devart\" page of the Tool Palette in RAD Studio.

Step 2: Create a New Project

Open RAD Studio and create a new VCL Application project in Delphi. Save the project as \"MyDACDemo\".

Add a TMyConnection component to the main form and name it \"MyConnection\". This component represents a connection to a MySQL server. Double-click on it to open the Connection Editor dialog box.

In the Connection Editor, enter the following parameters:

Host: The name or IP address of your MySQL server.

Port: The port number of your MySQL server (default is 3306).

User name: The user name for accessing your MySQL server.

Password: The password for accessing your MySQL server.

Database: The name of the database you want to use (in this case, \"sakila\").

Click on the \"Test Connection\" button to check if the connection is successful. If not, check your parameters and try again. If yes, click on the \"OK\" button to save the connection settings.

Step 3: Add Data Access Components

Add a TMyQuery component to the main form and name it \"MyQuery\". This component represents a SQL query that can be executed on the MySQL server. Double-click on it to open the SQL Editor dialog box.

In the SQL Editor, enter the following SQL statement:

select * from actor

This query will retrieve all records from the \"actor\" table in the \"sakila\" database. Click on the \"Execute\" button to run the query and see the results in the Data Grid tab.

Add a TDataSource component to the main form and name it \"DataSource\". This component provides an interface between a data-aware control and a dataset component (such as TMyQuery). Set its DataSet property to \"MyQuery\".

Add a TDBGrid component to the main form and name it \"DBGrid\". This component displays and edits data from a dataset component (such as TMyQuery) in a tabular format. Set its DataSource property to \"DataSource\".

Step 4: Run the Application

Save and run the application. You should see a window with a grid that shows the data from the \"actor\" table in the \"sakila\" database.

You can use the DBGrid component to browse, edit, insert, or delete records from the table. You can also use the MyQuery component to execute other SQL statements on the MySQL server.
