I open a table, when I use fetchall:=true - I can close it without any error.
When I set fetchall:=false I get a EMySQLException "Lost connection to mysql server during query".
I can´t send you a small program to reproduce that error but what can go wrong to get this error?

"I can´t send you a small program to reproduce that error but what can go wrong to get this error?"

Hey Tobias,
Thanks for getting back to us!

Please be informed, that such MyDAC behaviour may be casued to the specifics of working with with not fetched data.
You may only see the error "Lost connection to MySql server during query" if you run your application from the IDE.
Kindly note, that you should not see this error when you run the executable file of your application.

Please be aware that such MyDAC behavior may be due to the complexities of dealing with unfetched data.
