2.3.20.1 NdbError::Classification

Description.  This type describes the type of error, or the logical group to which it belongs.

Enumeration values.  Possible values are shown, along with descriptions, in the following table:

Value Description
NoError Indicates success (no error occurred)
ApplicationError An error occurred in an application program
NoDataFound A read operation failed due to one or more missing records.
ConstraintViolation A constraint violation occurred, such as attempting to insert a tuple having a primary key value already in use in the target table.
SchemaError An error took place when trying to create or use a table.
InsufficientSpace There was insufficient memory for data or indexes.
TemporaryResourceError This type of error is typically encountered when there are too many active transactions.
NodeRecoveryError This is a temporary failure which was likely caused by a node recovery in progress, some examples being when information sent between an application and NDB is lost, or when there is a distribution change.
OverloadError This type of error is often caused when there is insufficient logfile space.
TimeoutExpired A timeout, often caused by a deadlock.
UnknownResultError It is not known whether a transaction was committed.
InternalError A serious error has occurred in NDB itself.
FunctionNotImplemented The application attempted to use a function which is not yet implemented.
UnknownErrorCode This is seen where the NDB error handler cannot determine the correct error code to report.
NodeShutdown This is caused by a node shutdown.
