Chris,

in FDB, all Firebird errors are reported as Python exceptions. For more
details about FDB you can use KInterbasDB documentation at
http://www.firebirdsql.org/file/documentation/drivers_documentation/python/3.3.0

While there are differences between these drivers, FDB is developed as
direct replacement for KInterbasDB, so it follows the KDB interface and
functionality as close as possible.
