- because it was written this way many years ago (before it became Firebird)
- because without original lowest-level error it is impossible to find a reason
for failure
- because in most cases it is obvious what Firebird did at failure moment
I agree that sometime more context from intermediate levels could help to
better
understand what happens. For example, when transliterate error happens it is
good
to know assignment destination (field or variable) name. I'm not sure it is
easy to
implement. But in the case of "CreateFile failed" when index is built... - i
see nothing
to add here, it is clear enough as for me...
