sqlapi.exceptions
...
- DB-API exceptions.
-
C
DataError

the processed data like division by zero, numeric value
out of range, etc. It must be a subclass of DatabaseError.
-
C
InterfaceError

- Exception raised for errors that are related to the
database interface rather than the database itself. It
must be a subclass of Error.
-
C
InternalError
...
- Exception raised when the database encounters an internal
error, e.g. the cursor is not valid anymore, the
transaction is out of sync, etc. It must be a subclass of
DatabaseError.

database's operation and not necessarily under the control
of the programmer, e.g. an unexpected disconnect occurs,

be processed, a memory allocation error occurred during
processing, etc. It must be a subclass of DatabaseError.
-
C
Error
...
- Exception that is the base class of all other error
exceptions. You can use this to catch all errors with one

be a subclass of the Python StandardError (defined in the
module exceptions).

...
- Exception raised for errors that are related to the
