TMySQL57Connection
Note: Instead of using a TMySQL57Connection a proxy-like TSQLConnector may be used to create more generic database applications
TMySQL57Connection 
is the database connection component for use with an installed MySQL version 5.7 client library. However, the server SQL-version may be different from the client. The component is found on SQLdb tab of the Component Palette.
On linux it may be necessary to install libmysqlclient20 to provide the required libmysqlclient.so.20
