DYNAMIC EDatabaseError* __fastcall AccessError(const System::UnicodeString TypeName);
Description
Creates en error message and returns an EDatabaseError exception.
The AccessError method creates an error message customized according to the data type name passed as parameter, and returns an EDatabaseError exception containing the error message. The exceptions are raised by the protected setter and getter methods of the properties in the TField class.
For example, when attempting to set the AsAnsiString property, an exception is raised. That is because those methods are to be implemented in subclasses of TField.
