Hello.

MyDAC distribution includes a demo project located in the "MyDacDemo" folder in Demos of MyDAC. Please check if the problem can be reproduced on this demo project.

Hello.

In this case the 'Lost connection to MySQL server during query' error is an internal MyDAC error that is used for internal purposes.
Such MyDAC behaviour is correct, it is caused by specificity of working with not fetched data.
You will see the 'Lost connection to MySql server during query' error only if you run your application from the IDE.
You will not see this error when you run the executable file of your application.
