Description

The event fires if an error occurs while the script engine is communicating with a DBMS.

The event handler of OnError receives the following parameters:

• ASender is the script.
• AInitiator is the object that raises the exception.
• AException is the exception. It is usually an instance of EFDDBEngineException.

You can handle OnError to analyze and modify an exception raised while the script engine is communicating with a DBMS. You can even create a new exception object and assign it to AException; if you do so, you must free the original exception object.

This event should not be used to produce an end-user output regarding the exceptions.
