Please be advised that the error message "Lost connection to
MySql server during
query" during debugging in the
IDE is not a bug. These are the features of the scenario of our components' operation.
In order to be able to suppress this
exception and at the same time not affect other exceptions that notify real issues, we will add a new class - EMySqlNetException = class(EMySqlException) for the MySqlNet module for generating internal errors.
This will allow us to suppress the output of this error message (which can occur when FetchAll = False and is then correctly processed by us, but is issued as an
exception in the
IDE) for the new
exception class while leaving accessible all other important
exception classes (messages about a real issue) for display.
Könnte eventuell auch für andere hilfreich sein.
